Regulation of the growth performance and the gastrointestinal microbiota community by the addition of defective pear fermentation to feed of small-tailed Han sheep. Front Microbiol 2024; 15:1358033. [PMID: 38638905 PMCID: PMC11024308 DOI: 10.3389/fmicb.2024.1358033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 03/18/2024] [Indexed: 04/20/2024] Open
Abstract
This study investigated the effects of defective pear fermentation (DPF) diets on growth performance and gastrointestinal microbial communities in 60 healthy male small-tailed Han sheep, aged 90 days. The sheep were randomly divided into four groups, each consisting of three replicates with five sheep per replicate. Initially, all groups received a basal diet for seven days during the adaptation stage. Subsequently, for 60 days, group C (control) was fed a basal diet, group X received a basal diet with 2% DPF, group Y had a basal diet with 4% DPF, and group Z was fed a basal diet with 6% DPF. The results indicated that group Y experienced a significant increase in average daily gain (ADG) and average daily feed intake (ADFI). The addition of DPF significantly elevated the levels of GSH-Px and notably reduced MDA content compared to group C. Analysis of gastrointestinal microbiota showed that groups receiving DPF had increased relative abundances of Lachnospiraceae_NK3A20_group, norank_f p-2534-18B5_gut_group, Acetitomaculum, Actinobacteriota, Bacteroidota and Ruminococcus_gauvreauii_group, and decreased abundances of Proteobacteria, Prevotella, Staphylococcus, and Psychrobacter compared to group C. Group X exhibited the highest relative abundance of Olsenella, while group Y showed a significant increase in unclassified_f Lachnospiraceae compared to the other groups. Bacterial function prediction indicated that pathways related to energy metabolism were more prevalent in group X and Y. This study preliminarily confirms the feasibility of using DPF as feed additives, providing a foundation for further research and evaluation of DPF's application in animal production.

Abstract
Traditional sheep grazing is the pillar industry and the main source of income for local herders in the Inner Mongolia Autonomous Region of China. However, grazing sheep often suffer from mineral deficiency. In the present study, the feeding experiment was performed on 84 grazing Wu Ranke sheep. After being divided into calcium (Ca), zinc (Zn), copper (Cu), cobalt (Co), manganese (Mn), and selenium (Se) treatment groups, they were fed with a mineral deficient diet for 60 days and then a mineral supplement diet for 41 days. Serum samples were collected three times, 10 concentrations of essential mineral elements and 15 concentrations/activity of biochemical parameters were measured to assess the effects of mineral deficiency and supplementation on the physical health of sheep. The results revealed that the sheep showed mineral Ca, Cu, Co, Mn, and Se deficiencies after feeding their respective mineral deficient diet. Deficiency in dietary Ca, Zn, Cu, Co, Mn, and Se may adversely affect the liver, myocardium and pancreas of sheep. The prompt supplementation of dietary Zn, Cu, Co, Mn, and Se may alleviate the damage caused to the liver, myocardium and pancreas, while that of dietary Ca improved energy generation. In conclusion, the adequate supplementation of dietary Ca, Zn, Cu, Co, Mn, and Se is essential for avoiding the impairment caused to the liver, myocardium and pancreas function of sheep by the deficiency in essential dietary minerals.

Abstract
This research is to study the effects of nano-Cu2O on blood parameters, growth performance, and wool yield in the Cu-stripped ranches, and provide reference for further study on prevention and treatment in Cu-deficient Chinese Merino sheep. We selected twenty Chinese Merino sheep from Cu-deficient and normal ranch, respectively. The results have shown that the Cu content in the soils, forages, blood, and wool from Cu-deficient ranches was significantly lower than those from normal ranches (P < 0.01). There were no significant differences in the contents of other elements. Treatment experiments of nano-Cu2O were carried out for 50 days. We found that the Cu content in the blood was increased continuously in the sheep after adding nano-Cu2O, and reached the highest level at 40 days. The levels of Hb, RBC, PCV, MCV, and MCH in the nano-Cu2O-fed animals were remarkably higher than those in the control animals (P < 0.01). The daily gain and wool yield in the nano-Cu2O-fed animals were also significantly higher than those in the control sheep (P < 0.01). Therefore, adding nano-Cu2O not only remarkably increases the Cu content in the blood, but also greatly improves the daily gain and wool yield in Cu-deficient animals.

Supplementary Feeding of Grazing Inner Mongolian Cashmere Goats during Pregnancy-Based on "Nutrient Requirements of Cashmere Goats". Animals (Basel) 2023; 13:ani13030473. [PMID: 36766362 PMCID: PMC9913870 DOI: 10.3390/ani13030473] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 01/23/2023] [Accepted: 01/26/2023] [Indexed: 02/01/2023] Open
Abstract
This study aimed to conduct precise supplementation for pregnant cashmere goats under grazing based on the feeding standard. Eight Inner Mongolian pregnant cashmere goats of near-average body weight were selected at early gestation (44.41 ± 4.03 kg) and late gestation (46.54 ± 4.02 kg) to measure their nutrient intake. Then, two pregnant cashmere goat flocks, No. 10 (control group, on-farm supplement) and No. 11 (supplemented group, supplement based on standard), with the same goat herd structure and grassland type, were chosen to conduct the supplemental feeding experiment. The results showed that pregnant cashmere goats lacked daily the intake of dry matter, digestive energy, crude protein and most essential mineral elements under grazing. After supplemental feeding, the supplementation based on the feeding standard increased the cashmere length and cashmere length growth volume and decreased the cashmere fineness, with no statistical significance. The goat cashmere yield, goat weight after shearing, single and twin-birth kid weight and kids' mature secondary hair follicle density were significantly higher in the supplemented group (p < 0.05). In conclusion, supplementation in accordance with "Nutrient Requirements of Cashmere Goats" can enhance pregnant cashmere goats' fiber production, growth performance, fertility and kids' secondary hair follicles development, which is of great importance for the healthy and precise nutrition and management of cashmere goats.

Abstract
The land application of biosolids can result in the unacceptable accumulation of Trace Elements (TEs) in agricultural soil and potentially introduce xenobiotics and pathogens into the food chain. Phytoremediation of biosolids aims to minimize this risk, while producing valuable biomass. Willows, well known to accumulate zinc (Zn), are used extensively in farming systems for soil conservation, shelter and as feed supplements with demonstrable health benefits. Potentially, biosolids phytoremediation could occur on marginal lands adjacent to farmlands where willows are grown for supplementary fodder. We aimed to determine the uptake and distribution of Zn and other TEs in willows grown on soils amended with biosolids and biosolids blended with biochar, with a view to their use as stock fodder. In the Canterbury Region, New Zealand, we grew Salix 'tangaio' (S. matsudana X S. alba) in a greenhouse trial and field study. The biomass production of the willows was unaffected by biosolids and increased by the biosolids+biochar mixture. The addition of 4% biosolids (w/w) to the soil resulted in a foliar Zn concentration of 600-1000 mg kg-1, some 25 times higher than the average New Zealand pasture. Zinc concentrations were highest in the bottom leaves and increased throughout the season. Biosolids addition doubled the copper (Cu) concentration to 10 mg kg-1. Adding biochar to the system reduced the plant uptake of Cu and to a lesser extent Zn, while cadmium (Cd) uptake was unaffected. For Cd, Cu, and Zn, plant uptake was a function of the Ca(NO3)2-extractable concentration, both in greenhouse experiments and the field trial. Future work should determine the changes in plant TE uptake over several growing seasons.

Abstract
The study was implemented for exploring influences of nano-K2MoO4 on the daily gain and antioxidant function of Chinese merino sheep in the native pasture, Xinjiang Uygur Autonomous Region, Northwest of China. Eighty of the sheep, weight of (45.56 ± 2.35) kg, were randomly distributed to the tested areas for 90 days, 20 sheep/group. The findings showed that the contents of Mo and N in the forage of applying nano-K2MoO4 were extremely higher than those in the control pastures (P <0.01). The daily gain in the fertilized groups were remarkably lower than that in the control group (P <0.01). The harvest of forage in the fertilized pastures were significantly higher than those in control (P <0.01). The contents of Mo in blood and liver in grazing the Chinese merino sheep were extremely higher than those from the control group (P <0.01). The contents of Cu in blood and liver in grazing the Chinese merino sheep were extremely lower than those in the unfertilized pastures (P <0.01). The levels of hemoglobin (Hb), blood platelet (PLT), and erythrocyte count (RBC) in animals from the fertilized pastures were extremely lower than those in the control pastures (P < 0.01). The activities of SOD, GSH-Px, and CAT in serum were significantly lower than those in group C. The serum MDA levels were significantly higher than those in the control group (P < 0.01). In conclusion, the application of nano-K2MoO4 in pastures can greatly improve the yield of forage, but strikingly decreased the daily gain and antioxidant function in grazing the Chinese merino sheep.

Novel organic selenium source hydroxy-selenomethionine counteracts the blood-milk barrier disruption and inflammatory response of mice under heat stress. Front Immunol 2022; 13:1054128.

Abstract
Heat stress (HS) in summer has caused huge economic losses to animal husbandry production recently. When mammary gland is exposed to high temperatures, it will cause blood-milk barrier damage. Hydroxy-selenomethionine (HMSeBA) is a new selenium source with better guarantee of animals' production performance under stress, but whether it has protective effect on heat stress-induced blood-milk damage is still unclear. We established mammary epithelial cells and mice heat stress injury models to fill this research gap, and hope to provide theoretical basis for using HMSeBA to alleviate heat stress damage mammary gland. The results showed that (1) Heat stress significantly decreases in vitro transepithelial electrical resistance (TEER) and cell viability (P < 0.01), and significantly decreases clinical score, histological score, and total alveoli area of mice mammary gland tissue (P < 0.01). (2) HMSeBA significantly increases TEER and fluorescein sodium leakage of HS-induced monolayer BMECs (P < 0.01), significantly improves the milk production and total area of alveoli (P < 0.01), and reduces clinical score, histological score, mRNA expression of heat stress-related proteins, and inflammatory cytokines release of heat-stressed mice (P < 0.01). (3) HMSeBA significantly improves tight junction structure damage, and significantly up-regulated the expression of tight junction proteins (ZO-1, claudin 1, and occludin) as well as signal molecules PI3K, AKT, and mTOR (P < 0.01) in heat-stressed mammary tissue. (4) HMSeBA significantly increases glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), and superoxide dismutase release (SOD) (P < 0.01) and significantly reduce malondialdehyde (MDA) expression (P < 0.01) in heat-stressed mammary tissue. In conclusion, this study implemented heat-stressed cell and mice model and showed that HMSeBA significantly regulate antioxidant capacity, inhibited inflammation, and regulate tight junction proteins expression in blood-milk barrier via PI3K/AKT/mTOR signaling pathway, so as to alleviate mammary gland damage and ensure its structure and function integrity.

Abstract
The purpose of this study is to investigate the effects of molybdenosis on antioxidant capacity in endangered Przewalski's gazelles (Procapra przewalskii) in the animal rescue center in the Qinghai Lake National Nature Reserve in Northwestern China. Ten P. przewalskii in molybdenosis were selected and treated orally with copper sulfate (CuSO4) at a dose of 20 g/animal/5 days for 20 days. Ten healthy P. przewalskii were also selected and allocated to healthy pastures for 20 days. Samples of soil, forage, and animal tissue were collected. The values of mineral and hematological parameters were measured. Results showed levels of molybdenum (Mo) in soil and forage were significantly higher than those in healthy ranches (P < 0.01). The Mo content of blood and hair in gazelles from the rescue center was also significantly higher than those in the healthy ranches animals (P < 0.01). The copper (Cu) contents in blood and hair from the rescue center were significantly lower than those from the healthy pasture (P < 0.01). Hemoglobin (Hb) and red cell volume (PCV) in the gazelles from the animal rescue center were significantly lower than those from animals in healthy ranches (P < 0.01). Aspartate aminotransferase (AST), lactate dehydrogenase (LDH), phosphocreatine kinase (CPK), and alkaline phosphatase (ALP) were significantly higher than those from gazelles in healthy ranches (P < 0.01). The antioxidant capacity in gazelles from the animal rescue center was significantly lower than that of gazelles in healthy ranches. Supplementing CuSO4 significantly decreased the Mo content of blood and cured molybdenosis in gazelles. In summary, the Mo content of soil and forage was very excessive for gazelles in the animal rescue center. The antioxidant capacity of P. przewalskii has been seriously affected by molybdenosis.

Abstract
To study the effects of the seleno-chitosan on daily gain, wool yield, and blood parameters in the Chinese merino sheep in the selenium (Se)-deficient pastures. The samples of soils, forages, and tissues had been collected in the Southern Xinjiang of Northwest China. Our findings indicated that the Se contents in soils and forages from affected pastures were remarkably lower than those unaffected by the pastures (P < 0.01). The Se contents in the blood and the wool from affected Chinese merino sheep were extremely lower than those from healthy sheep. Meanwhile, the values of Hb, PCV, and PLT in affected sheep were significantly decreased (P < 0.01). The yield of wool and the growth rate in affected sheep were also remarkably reduced (P < 0.01). The affected Chinese merino sheep were orally treated by seleno-chitosan for 150 days; the Se contents in blood were remarkably increased and reached the healthy range on day 5. The blood parameters soon recovered to a healthy range on day 10. The growth rate of sheep in the treated group was remarkably higher than that in the control animals. The yield of the wool was also significantly increased in the treated group. Consequently, the Se-deprived environment caused a threat to daily gain, wool yield, and blood parameters in the Chinese merino sheep. The seleno-chitosan could not only markedly increase the Se contents blood contents, but also significantly increase the production performance (daily gain and wool yield), and release the symptoms of anemia in the Se-deprived animal.

Abstract
The aims of this study were to investigate the impact of different levels of nano-potassium molybdate (nano-K2MoO4) fertilization on the copper (Cu) metabolism in grazing the Pishan red sheep in the natural pasture. The fertilization and grazing experiments were conducted on the Pishan farm in Southern Xinjiang, China. The natural pastures of 16 hm2 were randomly divided into four groups (4 hm2/group), consisting of group C (no fertilized), group I, group II, and group III. The fertilizing amount of Mo from nano-K2MoO4 was 0, 7, 8, and 9 kg/hm2 for group C, group I, group II, and group III, respectively. The 40 Pishan red sheep were randomly distributed to the tested pastures for 90 days, and the 10 sheep/group. The results showed that the contents of Mo and N in forage from the fertilized pastures were extremely increased (P < 0.01). The yield and dry matter digestibility of forage in fertilized pastures were significantly higher than those in no fertilized pasture (P < 0.01). The values of crude protein (CP) and crude fat (EE) in forage from fertilized pastures were significantly increased (P < 0.01). The Mo contents in the blood and liver in the Pishan red sheep from fertilized pastures were greatly increased (P < 0.01). The Cu contents in the blood and liver in the Pishan red sheep from the fertilized pastures were greatly decreased (P < 0.01). The activities of serum superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and total antioxidant capacity (T-AOC) in group I, group II, and group III were extremely lower than those in group C (P < 0.01), and the contents of serum malondialdehyde (MDA) in group I, group II, and group III were greatly higher than those from group C (P < 0.01). In summary, the application of nano-K2MoO4 improved the nutritive values and the yield of forage, but overuse will remarkably reduce the Cu contents of blood and greatly interfere with the Cu metabolism, leading to the Cu deficiency and low antioxidant capacity in grazing the ruminants.

Abstract
The Procapra przewalskii inhabits in a selenium (Se)-deprived environment in long-term, but they have no pathological manifestations due to the Se deprivation. This study aimed to reveal the underlying adaptation induced by Se deprivation. In the analysis, a total of 93 significantly changed metabolites were identified in positive and negative ion modes, including 46 upregulated and 47 downregulated compounds in the Se-deprived group. The differential metabolites were annotated as the major molecules in bile acid biosynthesis, biosynthesis of unsaturated fatty acids, and pyrimidine metabolism, respectively. This study systematically analyzed the serum metabolomics characteristics of P. przewalskii under Se-deprived conditions for the first time, providing a basis for further understanding of the metabolic mechanism of P. przewalskii in the Se-deprived environment.

Abstract
We have found that the Reclamation merino sheep in Southern Xinjiang, China, showed emaciation, stiff limbs, instability, and sudden death, which is related to the impairment of immune function and antioxidant capacity caused by selenium (Se) deficiency. The experiments were to study the effects of Se-enriched malt on the immune and antioxidant function in Se-deprived Reclamation merino sheep in Southern Xinjiang, China. The samples of soil and forage had been collected from tested pastures, and animal tissues were also collected in tested animals. The mineral content of soil, forage, and animal tissues was measured in the collected samples. Hematological indexes and biochemical values were also examined. The findings showed that the Se contents were extremely lower in affected soil and forage than those from healthy soil and forage (P < 0.01). The Se contents in affected blood and wool were also extremely lower than those from healthy blood and wool (P < 0.01). The values in glutathione peroxidase and total antioxidant capacity in affected serum samples were also extremely lower than those from healthy serum samples, and levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide were extremely higher in affected serum samples than those from healthy serum samples (P < 0.01). Meanwhile, the values of hemoglobin, packed cell volume, and platelet count from affected blood were extremely lower than those from healthy blood (P < 0.01). The levels of interleukin (IL)-1β, IL-2, tumor necrosis factor-alpha, immunoglobulin A, and immunoglobulin G in serum were extremely decreased in the affected Reclamation merino sheep (P < 0.01). The levels of IL-6 and immunoglobulin M in serum were extremely reduced in the affected Reclamation merino sheep compared to healthy animals (P < 0.01). The animals in affected pastures were orally treated with Se-enriched malt, and the Se contents in blood were extremely increased (P < 0.01). The immune function and antioxidant indicator returned to within the healthy range. Consequently, our findings were indicated that the disorder of the Reclamation merino sheep was mainly caused by the Se deficiency in soil and forage. The Se-enriched malt could not only markedly increase the Se content in blood but also much improve the immune function and the antioxidant capacity in the Se-deprived Reclamation merino sheep.

Abstract
Kazakh sheep are vital to the production system of the Barkol prairie. The purpose of this study was to determine the effect of nano-copper oxide (Nano-Cu2O) on the antioxidant system of Cu-deficient Kazakh sheep in the Barkol prairie in Xinjiang, China. We analyzed mineral contents in soil, forage, and animal tissues. Blood parameters were also measured at the same time. The results showed that compared with healthy grassland, the Cu content in the soil and forage in Cu-deficient pastures was significantly lower than that in healthy grassland (P < 0.01). The Cu content in the blood, wool, and liver of Cu-deficient Kazakh sheep was significantly lower than that of healthy animals (P < 0.01). After Kazakh sheep were supplemented with Nano-Cu2O or CuSO4, the blood Cu concentration increased significantly (P < 0.01). From the 5th day, the Cu content of the Nano-Cu2O group was significantly higher than that of the CuSO4 group. The levels of hemoglobin (Hb), erythrocyte count (RBC), and packed cell volume (PCV) in the two experimental groups were significantly higher than those in Cu-deficient Kazakh sheep (P < 0.01). Compared with Cu-deficient Kazakh sheep, the serum ceruloplasmin (Cp) level of the two experimental groups increased significantly (P < 0.01), while the serum lactate dehydrogenase (LDH), alkaline phosphatase (AKP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) decreased significantly (P < 0.01). Compared with Cu-deficient Kazakh sheep, the activities of serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and total antioxidant capacity (T-AOC) in Nano-Cu2O and CuSO4 groups increased significantly (P < 0.01), while the level of serum malondialdehyde (MDA) decreased significantly (P < 0.01). Therefore, Nano-Cu2O could not only significantly increase the Cu content in the blood of Cu-deficient Kazakh sheep, but also greatly improve the antioxidant capacity.

Abstract
The experiments were to study the effects of Se-yeast on immune and antioxidant in Selenium(Se)-deprived Pishan red sheep in Southern Xinjiang, China. The samples of soil, forage, and animal tissues were collected, and used for measuring mineral content, physiological parameter, and biochemical values. These findings showed that the Se contents in affected soil and forage were markedly lower than those from unaffected soil and forage (P < 0.01). Se in affected blood and wool were also extremely lower than those from healthy Pishan red sheep (P < 0.01). The hemoglobin, packed cell volume, platelet count, Glutathione peroxidase, and total antioxidant capacity in the affected Pishan red sheep were markedly lower than those from healthy ones too (P < 0.01). The levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide in Pishan red sheep from affected pastures were extremely higher than those from healthy ones (P < 0.01). The levels of interleukin (IL)-1β, Interleukin-2, tumor necrosis factor-α and interleukin-6 from serum were markedly decreased in affected Pishan red sheep(P < 0.01). The Pishan red sheep in Se-deprived pasture were treated by orally with Se-yeast, the amount of Se in the blood markedly increased in treated animals. Meanwhile, the immune and antioxidant indicator was returned to the healthy values. Consequently, our findings were indicated that Se-deprived forage caused oxidative damage, and a serious threat to the immune function in animals. The Se-yeast is more effective in the Se-deficient Pishan red sheep including blood Se content, immune function and the antioxidant capacity.

Abstract
Copper (Cu) is an essential trace element, but excessive Cu intake can induce poor performance and Cu poisoning and result in various health problems. Cu and molybdenum (Mo) antagonize each other in vivo. Therefore, Mo can reduce the absorption and utilization of Cu. The aims of this study were to investigate the impacts of Mo fertilization on antioxidant capacity of grazing Nanjiang brown goat on Cu-polluted meadow and explore the control methods of Cu pollution in natural pasture. Fertilization and grazing experiments were carried out in Liangshan Yi Nationality Prefecture of the Western Sichuan Plateau, Sichuan Province, Southwest China. Cu-polluted meadows of 12 hm2 were fenced, and randomly divided into two groups (3 replications/group, 2 hm2/replication), control group and treatment group, fed with basic diets supplemented with 0 and 3 kg Mo/hm2 [ammonium molybdate tetrahydrate, (NH4)6Mo7O24·4H2O], respectively. In the current study, 36 healthy Nanjiang brown goats (1 year old, 32.8 ± 1.1 kg) were randomly divided into two groups (3 replications/group, 6 goats/replication) and assigned to the experimental pastures. The grazing experiment lasted for 60 days. The results showed that the concentration of Mo in soil in treatment group was 96.28 mg/kg, far exceeding the normal levels. At days 30 and 60, the levels of Hb, RBC, and PCV in blood in treatment group and the activities of serum SOD, GSH-Px, T-AOC, CAT, and Cp were higher than those in control group (P < 0.01). The MDA content in treatment group was lower than that in control group (P < 0.01). The contents of Cu in blood and liver in treatment goats were lower than those in control animals (P < 0.01). The contents of Zn and Mo in blood and liver in treatment goats were higher than those in control animals (P < 0.01). The Mn content in liver in treatment group was higher than that in control animals (P < 0.01). These results indicated that fertilization of (NH4)6Mo7O24 not only markedly influenced the mineral contents in blood and liver, but also extremely improved antioxidant capacity of grazing Nanjiang brown goat from fertilized pastures and relieved the damage caused by Cu pollution.

Abstract
The fencing device on pasture has seriously restricted the foraging range in grazing animals. As a result, the incidence of selenium (Se) deficiency is rising in grazing Choko yaks in the Shouqu prairie in Northwest China. To study the effect of Se deprivation on antioxidant capacity in the Choko yaks, the mineral contents in soil, forage, blood, and liver have been analyzed. The parameters of physiology and biochemistry in animal were also measured. The tested results showed that Se contents in soil and forage from tested pastures were very greatly lower than those in the control ranges (P < 0.01), and there were no extreme differences in other elements. Se contents in blood and the liver in tested animals were very extremely lower than those in the control yaks (P < 0.01). Levels of hemoglobin (Hb), erythrocyte (RBC), and hematocrit (HCT) were very extremely less than those in the control group (P < 0.01). Activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT), and total antioxidant capacity (T-AOC) in blood from the tested yaks were very much lower than those in the control animals (P < 0.01). Contents of malondialdehyde (MDA) in tested yaks were extremely higher than those in the control animals (P < 0.01). Therefore, it is suggested that Se-deficient forage in natural habitat not only influenced mineral contents in the blood and the liver but also causes serious harm to antioxidant function in the Choko yaks.

Abstract
The Wumeng semi-fine wool sheep is vital to the production system in Southwest China. To study the effects of nano-selenium (Nano-Se) poisoning in the Wumeng semi-fine wool sheep, poisoning model was established. A total of 20 animals with an average initial body weight (BW) of 35.57 ± 3.31 kg were used in this study. After 1-week-long acclimatization period, all animals were randomly divided into two groups: (1) control, with no any treatment; (2) Nano-Se group, orally administered 5 mg Nano-Se (BW/kg/day). There were 10 replications/group and one sheep/replication. The experiment lasted for 30 days. Compared with the control, hemoglobin, erythrocyte count, and packed cell volume in Nano-Se group markedly decreased (P < 0.01), and the activities of serum lactate dehydrogenase, glutamic oxaloacetic transaminase, cereal third transaminase, and alkaline phosphatase in Nano-Se group significantly increased (P < 0.01). T3 and FT3 in serum in Nano-Se group were greatly lower than those in the control (P < 0.01). Contents of T4, FT4, and TSH in serum in Nano-Se group were extremely higher than those in the control (P < 0.01). Levels of IgG, IgM, IgA, interleukin 2 (IL-2), and tumor necrosis factor-alpha (TNF-α) in Nano-Se group were much lower than those of the control (P < 0.01), but levels of interleukin 6 (IL-6) and interleukin-1β (IL-1β) were greatly higher than those in the control (P < 0.01). Compared with the control, serum superoxide dismutase, glutathione peroxide, total antioxidant capacity, and catalase from Nano-Se group extremely decreased (P < 0.01), and content of serum malondialdehyde in Nano-Se group markedly increased (P < 0.01). The current results indicated that the blood parameters in the Wumeng semi-fine wool sheep were affected by Nano-Se poisoning, and the immune function and antioxidant capacity were greatly reduced too.

Abstract
Guizhou black goats are essential to the production system in the Wumeng prairie in the Western China. This study aimed to determine the influence of nano-copper on antioxidant system in copper-deprived Guizhou black goats. We analyzed mineral contents in soil, forage, and goats' tissues. Blood parameters were also determined. The results showed that copper concentrations in soil and forage were significantly lower, and the iron content was significantly higher in affected compared with healthy area (P < 0.01). Copper concentrations in animal tissues (blood, liver, and hair) were significantly lower and iron content was significantly higher in affected compared with healthy goats (P < 0.01). After supplementation of nano-copper or copper sulfate, copper concentration in blood was significantly increased and iron content was significantly lower (P < 0.01). Compared with nano-copper group, the effect of copper sulfate was slower. Hemoglobin levels, erythrocyte count, and packed cell volume from nano-copper and copper sulfate groups were significantly higher than those in copper-deprived goats (P < 0.01). Compared with the copper-deprived Guizhou black goats, serum ceruloplasmin levels in nano-copper and copper sulfate groups were significantly increased, while serum lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and creatinine were significantly decreased (P < 0.01). Compared with the copper-deprived animals, serum superoxide dismutase, glutathione peroxidase, catalase, and total antioxidant capacity in nano-copper and copper sulfate groups were significantly higher, while serum malondialdehyde content was significantly lower (P < 0.01). The effect of copper sulfate group was significantly lower than that in nano-copper group (P < 0.01). Consequently, nano-copper could not only markedly increase the copper content in blood in copper-deprived Guizhou black goats but also much improves the antioxidant capacity.

Abstract
Selenium (Se) is an essential mineral nutrient for animals. Se deprivation can lead to many disorders and even death. This study investigated the response of Przewalski's gazelle (P. przewalskii) to Se-deprived environment. We found that Se deprivation in soil and forage not only influenced the mineral contents of the blood and hair in P. przewalskii, but also severely disrupted their blood parameters. We identified significant changes in the abundance of 146 proteins and 25 metabolites (P < 0.05) in serum, including the selenoproteins L8IG93 (glutathione peroxidase) and F4YD09 (Cu/Zn superoxide dismutase). Furthermore, the major known proteins and metabolites associated with the Se stress response in P. przewalskii were Cu/Zn superoxide dismutase, the vitamin K-dependent protein C, the C4b-binding protein alpha chain, complement component C7, lipase linoleic acid, peptidase D, thymidine, pseudo-uridine, L-phenylalanine, L-glutamine, PGA1, and 15-deoxy-delta-12,14-PGJ2. The main signaling pathways involved included complement and coagulation cascades, metabolic pathways, and stress granule formation. Our results indicate that the intake of Se-deficient forage elicited an oxidative stress response in P. przewalskii. These findings provide insights into the response mechanisms of this threatened gazelle to Se stress, and enable the development of conservation strategies to protect populations on the Qinghai-Tibetan Plateau. SIGNIFICANCE: This study is the first to point out the presence of oxidative stress in P. przewalskii in selenium-deficient areas through proteomics and metabolomics studies. These findings should prove helpful for conservation efforts aimed at P. przewalskii populations and maintenance of the integrity of their ecological environment.

Abstract
Tibetan gazelle (Procapra picticaudata) is an endangered ungulate in the Qinghai-Tibet Plateau, China. This study aimed to determine the influence of nano-Se on antioxidant system in Se-deprived P. picticaudata. We analyzed contents of mineral elements in soil, forage, and animal tissue. Blood parameters and antioxidant indexes were also determined. The results showed that Se concentrations in the soil and forage from affected pasture were significantly lower than those in healthy area (P < 0.01). Se concentrations in blood and hair from affected P. picticaudata were also significantly lower than those in healthy animals (P < 0.01). Meanwhile, the levels of Hb, RBC, and PCV in affected gazelle were significantly lower than those in healthy animal (P < 0.01). The activities of AST, ALT, LDH, CK, and UA content in affected animal were significantly lower than those in healthy gazelles (P < 0.01). The levels of SOD, GSH-Px, CAT, and T-AOC in serum were significantly lower and the MDA content was significantly higher in affected compared with healthy gazelle (P < 0.01). Affected P. picticaudata were treated orally with nano-Se, Se concentration in blood significantly increased and serum antioxidant indexes greatly returned to within the healthy range. Consequently, nano-Se could not only markedly increase the Se content in blood in Se-deprived P. picticaudata but also much improves the antioxidant capacity.

Abstract
To research responses of Chinese Merino Sheep (Junken type) to copper-deprived natural pasture, we analyzed mineral contents in soil, forage, and sheep tissues. Physiological and biochemical parameters were also determined. Results showed that copper concentrations in soil and forage from affected pastures were significantly lower than those in healthy ranges (P < 0.01). Copper contents in animal tissues (blood, liver, and wool) from affected Chinese Merino Sheep were also significantly lower than those in healthy sheep (P < 0.01). Hemoglobin levels, packed cell volume, mean corpuscular volume, and mean corpuscular hemoglobin from affected Chinese Merino Sheep were significantly lower than those in healthy animals (P < 0.01). Serum ceruloplasmin was significantly lower in affected Chinese Merino Sheep than that in healthy animals, while activities of lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase in serum were significantly higher in affected compared with healthy animals (P < 0.01). The levels of superoxide dismutase, glutathione peroxidase, total antioxidant capacity, and catalase in serum were significantly lower, and the malondialdehyde content was significantly higher in affected compared with healthy sheep (P < 0.01). The levels of interleukin-2, interleukin 6, interleukin-1β, immunoglobulin A, immunoglobulin M, and immunoglobulin G in copper-deprived sheep were significantly lower than those in healthy animals (P < 0.01). Copper deprivation in forage not only influenced the mineral content in blood but also severely disrupted blood parameters (physiology, biochemistry, immunity, and antioxidant) in Chinese Merino Sheep.

Abstract
Qianbei-pockmarked goats are vital to the production system of western China. This study aimed to determine the influence of nano-zinc on immune function in zinc-deprived goats. We analyzed the mineral concentrations in soil, forage, and animal tissue. Blood parameters and immune indexes were also determined. Results showed that the zinc concentrations in soil and forage from affected area were significantly lower than those in control area (P < 0.01). Zinc contents in tissues (blood and hair) from affected Qianbei-pockmarked goats were also significantly lower than those in healthy animals (P < 0.01). Levels of hemoglobin, erythrocyte count, and packed cell volume from affected animals were markedly lower than those in healthy animals (P < 0.01). Levels of lactate dehydrogenase, alkaline phosphatase, superoxide dismutase, glutathione peroxide, catalase, and total antioxidant capacity in serum in affected animals were significantly lower, and aspartate aminotransferase, alanine transaminase, malondialdehyde in serum were significantly higher than those in healthy goats (P < 0.01). The contents of immunoglobulin A, immunoglobulin M, immunoglobulin G, interleukin-2, interleukin 6, and interleukin-1β from affected animals were significantly lower than those in healthy animals (P < 0.01). The affected Qianbei-pockmarked goats were treated orally with nano-zinc, the concentration of zinc in blood significantly increased, and serum immune indexes greatly returned to that within the healthy range. It was concluded that nano-zinc could not only markedly increase the zinc content in blood of zinc-deprived goats but also much improve the immune function.

Abstract
To study responses of Procapra przewalskii to zinc (Zn) nutrition in physical habitat, we analyzed the content of mineral elements in soil, forage, and animal tissues. Physiological and biochemical indexes were also determined. The results showed that Zn contents in the soil and forage from affected pasture were significantly lower (P < 0.01) than those in unaffected areas. Zn concentrations in the blood, liver, and hair from affected P. przewalskii were also significantly lower (P < 0.01) than those in healthy animals. The levels of hemoglobin, erythrocyte count, and packed cell volume from affected P. przewalskii were significantly lower (P < 0.01) than those in healthy animals. Serum aspartate aminotransferase and alanine transaminase activities were significantly lower (P < 0.01) in affected P. przewalskii than in healthy animals, while serum lactate dehydrogenase and alkaline phosphatase levels were significantly higher (P < 0.01) in affected compared with healthy animals. The activities of superoxide dismutase, glutathione peroxidase, and catalase in serum were significantly lower and the malondialdehyde content was significantly higher (all P < 0.01) in affected compared with healthy animals. Affected P. przewalskii were treated orally with ZnSO4. The Zn content in the blood increased gradually and serum antioxidant indexes gradually returned to within the healthy range. Zn deprivation in forage thus not only influenced the blood mineral content but also severely disrupted blood parameters and antioxidant function in P. przewalskii.

Abstract
The Wumeng semi-fine wool sheep is vital to the production system of the Wumeng mountainous area in Southwest China. To study the effect of nano-copper poisoning in the Wumeng semi-fine wool sheep, nano-copper poisoning model was established in sheep. We determined blood physiological and biochemical parameters, immune indexes, and antioxidant indicators. The results showed that Hb, RBC, and PCV levels in blood from the nano-copper group were markedly lower (P < 0.01) than those in the control group. Serum LDH, AST, ALT, CPK, and Cp from the nano-copper group were significantly higher (P < 0.01) than those in control animals. Serum SOD, GSH-Px, CAT, and T-AOC from the nano-copper group were significantly lower (P < 0.01) than those in control sheep, and MDA content in serum from the nano-copper group were markedly higher (P < 0.01) than those in control sheep. The levels of IL-2, IL-6, IL-1β, IgA, IgM, and IgG from the nano-copper group were significantly lower (P < 0.01) than those in the control group. It was concluded that nano-copper poisoning could not only affect the immune function of Wumeng semi-fine wool sheep but also reduce the antioxidant capacity.

Abstract
Many environmental accidents have led to worldwide heavy metal pollution, raising concern about heavy metal toxicity in Southwest China. To study the effects of Cd and Pb in the environment on antioxidant function in Wumeng semi-fine wool sheep, contents of Cu, Zn, Mn, Mo, Fe, Se, Cd, and Pb were measured in irrigation water, soil, herbage, and animal tissues. Hematological and biochemical parameters were also determined. The concentrations of Cu, Zn, Cd, and Pb in affected samples of irrigation water, soil, herbage, and tissues were significantly higher than those in the control (P < 0.01). There was no significant difference in other element contents between affected pastures and control areas. The occurrence of anemia affected Wumeng semi-fine wool sheep. The activities of SOD, CAT, and GSH-Px in affected animals were significantly decreased than those in the control (P < 0.01). Content of MDA in serum in affected animals was significantly increased than that in control (P < 0.01). Serum T-AOC in affected animal was significantly lower than that in control (P < 0.01). Consequently, it is suggested that heavy metal contamination in natural habitat caused serious harm to antioxidant function in Wumeng semi-fine wool sheep.

Abstract
Przewalski's gazelle (Procapra przewalskii) is an endangered ungulate in the Qinghai-Tibet Plateau of China. This study aimed to determine the influence of selenium (Se) deprivation in the natural habitat on the immune index and antioxidant capacity of P. przewalskii. Samples of soil and forage were collected from affected and healthy areas, and animal tissues were collected from affected and healthy P. przewalskii. The samples were used for measuring mineral content and for hematological and biochemical analyses. The results showed that Se concentrations were significantly lower in the soil and mixed forage samples from the affected area than in those from the healthy area. The Se concentrations were significantly lower in blood and hair samples from affected P. przewalskii than in those from healthy P. przewalskii. Meanwhile, hemoglobin, packed cell volume, and platelet count of affected P. przewalskii were significantly lower than those of healthy P. przewalskii. The serum level of glutathione peroxidase and total antioxidant capacity were significantly lower and the serum levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide were significantly higher in affected P. przewalskii. The serum levels of interleukin (IL)-1β, IL-2, tumor necrosis factor-alpha, immunoglobulin A (IgA), and IgG significantly decreased and the serum levels of IL-6 and IgM significantly reduced in affected P. przewalskii compared with healthy P. przewalskii. Therefore, the findings indicated that Se deprivation in soil and forage caused oxidative stress damage and posed a serious threat to the immune function of P. przewalskii.

Abstract
As a consequence of contracted and fenced grassland, the incidence of edema pathema in the Hequ horse is rising. The main pathological symptoms are edema, emaciation, anemia, heterophilia, inappetence, and dyskinesia. To study the cause of edema disease in Hequ horse, the Hequ horse farm with a high incidence was chosen as the experimental pasture, and the Azi husbandry experimental station without edema disorder was the control pasture. The research methods in this paper are included: (1) The mineral contents in soil, forage, blood, and liver were analyzed. (2) Routine parameters and biochemical values in blood were also measured. (3) Conduct a prevention trial and a treatment experiment. The results showed that Se contents in soil and forage was much significantly lower than that in the control group (P < 0.01), and there was no significant difference in other elements. Se contents in blood and liver in affected animals were very significantly lower than those of the control group (P < 0.01). Hb, HCT, MCV, and MCH were greatly significantly lower than those in the control group (P < 0.01). Activities of GSH-Px in blood were very significantly lower than those of the control group (P < 0.01). Before the onset season of the disorder in the affected area, Na2SeO3 was used to conduct a prevention trial on 1576 Hequ horses. A dose of 0.03 mg Na2SeO3 was given orally per kilogram of body weight, once every 15 days and twice continuously. There was no edema illness that year. In the treatment experiment, 235 horses were administered Na2SeO3 orally at 0.04 mg per kilogram of body weight, once every 3 days for 4 consecutive times, and 198 horses were cured, with a cure rate of 84.26%. Therefore, it is possible that Hequ horse edema pathema is caused by Se deficiency in soil and forage.

Abstract
A study of the seasonal dynamics of copper (Cu) deficiency and its effects on the antioxidant system in Wumeng semi-fine wool sheep in Weining county was conducted. In addition, the concentrations of mineral elements in soil, grass, and blood of affected and healthy Wumeng semi-fine wool sheep were determined, and blood indices were measured. The results showed that Cu contents in soil, grass, and sheep blood from the experimental pasture were significantly lower than those from the control pasture (P < 0.05), while the Mo content in the samples from the experimental pasture were higher than those from the control pasture (P < 0.05). Hb, RBC, PCV, and MDA values in the blood of affected sheep were significantly higher than those of healthy sheep, the content of TP was significantly lower (P < 0.05), and the activities of CAT, GSH-Px, CP, SOD, POD, and TP in the blood of affected sheep were lower than those in healthy sheep (P < 0.05). A comparison of different months showed that the Cu content in soil was higher in November than in June and September. Hb, RBC, PCV, WBC, and the content of MDA in the blood of affected sheep was higher in November than in June and September; however, the change in CP, CAT, GSH-Px, POD, and TP showed the opposite trend. The content of Cu and Mo in soil, grass, and blood showed seasonal changes. Therefore, it is concluded that the seasonal dynamics of Cu deficiency in Wumeng semi-fine wool sheep in Weining was due to the content of Mo and Cu in soil and grass in different seasons, and high Mo concentration in grass affected Cu deficiency in sheep. The function of the antioxidant system of Wumeng semi-fine wool sheep was reduced as a result.

Abstract
Determination of wool mineral content to assess the animal' mineral status has been extensively used, but the results are controversial. One of the possible contributing factors is that the sampling material in previous studies was collected from a long staple, a fact that could mask the response to recent differences in mineral intake. Therefore, the aim of the present study was to test the sensitiveness of newly grown wool to different dietary mineral intake. Twenty Tsigai ewes were allocated into five dietary treatments with similar hay and concentrate intake but different premix inclusion rates in the concentrate (3, 4, 5, 6, and 7%). Wool was sampled on the left side from a 5 × 5 cm area using bent scissors at the beginning of the trial and from the very same area 28 days later. Samples after cleaning and mineralization were analyzed with ICP-OES (Perkin-Elmer, Optima 3300 DV) for calcium, phosphorus, magnesium, sodium, selenium, zinc, copper, and sulfur content. Long fleeces had significantly lower Ca and Se content compared to the newly grown wool samples of the group at the premix manufacturer's suggested level of supplementation (5%). Macrominerals in fresh wool did not respond to increased dietary supplementation. Se and Zn content of wool had a strong relationship with the daily intake (R2 = 0.95 and R2 = 0.97, respectively.) In conclusion, the mineral content of long fleeces can be different compared to recently developed wool fiber. This indicates that, in some cases, analyzing long staples for mineral status can be misleading. Our results showed that wool could be a sensitive indicator of low selenium and high zinc intake. Mineral interactions can significantly affect the actual availability of trace minerals; therefore, a more careful design of premixes is needed. The described method seems to be applicable in livestock farming, but the mineral interactions that may alter the results need to be further explored.
