Abstract
Brackish water is being progressively utilized in livestock farming across the globe where freshwater is scarce, potentially leading to detrimental consequences for animal health and performance. This study was conducted to determine effects of different brackish groundwater types on water and feed intake, nutrient utilization, ruminal fluid characteristics, and blood constituent concentrations in different breeds of goats and sheep in a 6 (animal types; AT) × 6 (water treatments; WT) Latin square design. Six AT (Boer, Spanish, and Tennessee Stiff-Leg does and Dorper, Katahdin, and St. Croix ewes) consumed drinking water differing in total dissolved solids (TDS) and mineral composition. Six WT were fresh water (FRW; 287 mg TDS/kg), a natural brackish water (BR) alone (100-BR; 5734 mg TDS/kg), BR with concentrations of all minerals increased by about 100 % (200-BR; 10,603 mg TDS/kg), FRW added with NaCl having similar TDS level (6654 mg/kg) as 100-BR (100-SL), FRW added with NaCl having similar TDS (12,197 mg/kg) as 200-BR (200-SL), and water with similar TDS (10,643 mg/kg) level as 200-BR by adding NaCl to 100-BR (200-BR/SL). Water treatment only affected (P < 0.05) water intake, total volatile fatty acids in ruminal fluid, blood phosphorus, blood aldosterone, and plasma osmolality. Water intake was greater (P < 0.05), but total ruminal volatile fatty acid concentrations were lower (P < 0.05) for 200-SL than other WT. Plasma osmolality and aldosterone concentrations were lower (P < 0.05) for 200-SL and 200-BR/SL than FRW. There were no significant interactions between WT and AT for any variable. Water and feed intake, digestibilities, ruminal ammonia concentration, and methane emission were similar among AT (P > 0.05). There were differences (P < 0.05) among AT for many ruminal fermentation and blood characteristics. Although there were some differences among WT, no AT seemed adversely affected by water with a TDS level near or slightly above 10,000 mg/kg regardless of mineral sources.

Effect of increased intake of concentrates and sodium butyrate supplementation on reticulorumen macroanatomy and reticulorumen fermentation in growing rams. Animal 2023; 17:100899. [PMID: 37558584 DOI: 10.1016/j.animal.2023.100899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 06/16/2023] [Accepted: 06/19/2023] [Indexed: 08/11/2023] Open
Abstract
Increased ruminal butyrate production is considered to have mostly positive impacts on rumen macro- and microanatomy and its functions. However, excessive ruminal butyrate production may also affect the rumen negatively. Forty-two growing rams were allocated into six treatments and fed a diet with low (22.5% of diet DM; LOW) or high (60% of diet DM; HIGH) inclusion of concentrates in combination with no, low (1.6% of diet DM) or high (3.2% of diet DM) sodium butyrate (SB) supplementation to obtain low or high reticuloruminal (RR) pH with different concentrations of butyrate. Both absolute (L/day) and relative (% of BW) water intake increased linearly with increasing dose of SB (P ≤ 0.02). The RR fluid pH was lower for HIGH compared to LOW treatments (P < 0.01) but was not affected by SB supplementation (P = 0.35). Total short-chain fatty acid concentration, propionate and valerate concentrations in the RR fluid were higher for HIGH compared to LOW treatments (P ≤ 0.01), but were not affected by SB supplementation (P ≥ 0.22). Reticuloruminal butyrate was higher for HIGH compared to LOW treatments and increased linearly with increasing dose of SB (P < 0.01). High concentrate inclusion in the diet (P < 0.01) decreased and SB supplementation tended to (P = 0.10) decrease fibrolytic activity in the RR. Increasing doses of SB linearly decreased acetate, isovalerate and NH3-N concentrations in RR fluid, and RR digesta DM weight (g DM/kg BW; P ≤ 0.02). Relative RR and rumen tissue weights (g/kg BW) were higher for LOW compared to HIGH (P ≤ 0.03) treatments but were not affected by SB inclusion in the diet (P ≥ 0.35). Also, there was no impact of concentrates or SB inclusion in the diet on ruminal epithelium DM weight (mg/cm2), either in the ventral or dorsal sac of the rumen (P ≥ 0.14). Under conditions of the current study, SB supplementation in the diet decreased RR digesta DM concentration and weight, acetate, isovalerate and NH3-N concentration in the RR fluid, and tended to reduce fibrolytic activity in the RR. At least part of this response could be due to increased intake of water, and consequently passage of digesta from the RR to lower regions of the gastrointestinal tract.

Abstract
Background and Aim Climate change challenges with incremental sea level cause saltwater intrusion, which has affected the quality of freshwater and groundwater in coastal provinces, particularly the Mekong River Delta provinces of Vietnam. Interestingly, Bach Thao goats are predominant in this area and well adapted to saline water under tropical conditions. Therefore, this study investigated the salt tolerance threshold of Bach Thao goats drinking diluted seawater (DSW). Materials and Methods The experiment was performed using seven Bach Thao male goats (20.60 ± 1.12 kg) and divided into two phases. In Phase 1 (control, C), all goats were provided fresh water (FW) for 7 days from two identical buckets, and daily water intake (WI) was recorded from both buckets. In Phase 2 (preference test, PT), each goat was provided FW from the first bucket and DSW from the second bucket or vice versa. The concentration of DSW for the preference test was 0.5%-2.0%. Results Body weight and dry matter intake showed no differences according to DSW consumption; however, WI was significantly lower during Phase 2 (p < 0.05), which was due to the lower WI with 1.5% and 2% of DSW (p < 0.05). Goats showed a similar preference for fluid intake between FW and DSW at 0.0%-1.0% levels and began avoiding DSW at 1.5% and rejected at 2.0% of DSW. Goats consuming 1.5% of DSW showed increased respiration rate from 13:00 to 19:00 h and rectal temperature at 13:00 h (p < 0.05). Conclusion Goats can tolerate up to 1.0% of DSW. Shifting to FW activated aversive drinking to 1.5% and 2.0% of DSW. This behavioral response was prominent at 0.5% DSW. Moreover, goats that drank 1.5% of DSW had decreased thermoregulation.

Abstract
ABSTRACT The aim of the study was to evaluate whether supplementation with different levels of selenium (Se) can change the biochemical and electrolytic components of semen, causing an improvement in seminal quality in rams. Thirty animals were kept in an intensive pen system, fed with hay and commercial ration, allocated into five groups (six animals/pen) and supplemented with a mineral mixture containing 0mg (G1), 5mg (G2), 10mg (G3), 15mg (G4) and 20mg (G5) of Se/kg. Each group received a different treatment every 56 days and treatments were rotated between groups following a dynamic sequence. Semen samples were collected by electroejaculation after the end of each treatment to evaluate the levels of fructose, citric acid, potassium (K), sodium (Na), calcium (Ca), Se, zinc (Zn), manganese (Mn), sulfur (S) and lead (Pb). The statistical design was a 5x5 Latin square. The different levels of Se supplementation evaluated maintained the concentrations of electrolytes and minerals in the semen at the required levels and did not change the sperm quality, concluding that higher intakes of Se do not cause antagonistic effects on the absorption and subsequent action of other essential minerals supplied to the animals and still maintains electrolyte balance.

Abstract
Horses lose high amounts of Na through excessive sweating. These fluid losses can often not be replaced completely by voluntary water intake, requiring saline solutions as rehydration therapy to regain electrolyte balance. The experiment aimed to evaluate the sensitivity and tolerance of Shetland ponies towards different Na concentrations in their drinking water and contained three phases: (1) control: only fresh water provided; (2) pairwise-preference test: choice between fresh water and saline solution with stepwise increasing sodium chloride (NaCl) concentration (0.25%, 0.5%, 0.75%, 1.0%, 1.25%, or 1.5%); and (3) free-choice test: six simultaneously provided buckets containing NaCl concentrations of 0%, 0.25%, 0.5%, 0.75%, 1.0%, or 1.25%. During the pairwise test, the ponies did not distinguish between fresh and 0.25% NaCl-water but demonstrated clear preference for 0.5%, whereas >0.75% NaCl was avoided/rejected. During the free-choice test, a pronounced preference of fresh over saline water was exhibited. The Na intake via salt lick was not reduced as response to higher Na intakes via water. The ponies exhibited a remarkable sensory discrimination capacity to detect different NaCl concentrations in their drinking water. The acceptance of solutions with low NaCl levels (0.25/0.5%) without adverse effects demonstrates potential as rehydration solution for voluntary intake.

Abstract
The chronic exposure of livestock to lead (Pb) pollution in historical mining areas may represent significant and unnecessary costs for farmers and primary producers, in addition to important food safety risks. Here, we evaluate the effect of mineral supplements, in the form of a commercial mineral block (MB), to reduce Pb bioavailability and toxicity in sheep through an experimental approach under real farming conditions in an abandoned mining area. Blood, fecal Pb levels, and soil ingestion, along with different blood and plasma biomarkers were studied. Experiment 1 was carried out with 3-months-old female lambs, n = 54, fenced in two contiguous MB and non-MB-supplemented plots. After 20 days of treatment, blood Pb level was lower in MB-supplemented sheep than in those that were non-MB-supplemented. Experiment 2 was carried out with 2-months-old female lambs, n = 34, fenced in a single plot and MB-supplemented during the first 20 days of experiment. After MB supplementation, blood Pb level in sheep was also reduced by almost half, falling below the threshold of subclinical intoxication, and then increased again after 20 days without MB. Experiment 3 was carried out with adult rams, n = 10, fenced in a single MB-supplemented plot during the first 20 days of experiment. In this case, blood Pb level decreased by day 40. Soil ingestion was not reduced by MB supplementation in any of the experiments. MB supplementation favored antioxidant status by increasing SOD activity and reducing GPX activity and MDA levels. In conclusion, the MB supplementation seemed to reduce Pb bioavailability by increasing its fecal excretion, but renal excretion and bone deposition may also have favored the reduction of blood Pb concentration. Mineral supplements may be a new easy-to-apply and cost-effective way to reduce livestock exposure in Pb polluted sites.

Abstract
To examine the adaptive physiological responses to increasing salinity of drinking water in a choice situation, twelve female non-lactating Boer goats were used. After a control period with fresh water, in phase 2 the choice between different salt concentrations (0.25, 0.5, 0.75, 1.0, 1.25 and 1.5% NaCl) and tap water was offered for two weeks. Subsequently, goats were stepwise habituated to saline water by only offering the choice between salted water with different increasing concentrations (up to 1.5% NaCl) for four weeks. In phase 4 the procedure of phase 2 was repeated. BW was not affected by saline water intake, whereas BCS decreased. Total water intakes differed between ages (P < .001), and increased (P < .001) from 91.6 to 118.0 g/kg BW0.82/day and from 105.5 to 142.9 g/kg BW0.82/day in young and old goats in phase 3, respectively. In adult goats, rumen temperature decreased (P < .05) with prolonged saline water intake, while it remained unaffected in young goats. Increasing consumption of saline water decreased plasma concentrations of magnesium (from 0.95 to a minimum of 0.80 mmol/L in phase 3, P < .001). Creatinine increased from 82.92 to 93.39 μmol/L in the post-trial period 4 (P < .02) and potassium concentration increased from phase 2 (P < .001). ALT, AST, glucose, urea, calcium, sodium, osmolality were unaffected. All measured blood parameters remained within reference ranges, indicating that the stepwise adaptation to saline drinking water applying concentrations up to 1.5% across 4 weeks caused no harmful effects. Young animals were less resistant to salt toxicity compared to older ones.

Abstract
Simple Summary With the recent negative public opinion on chemical-based feed additive in many nations of the world (for the health implication and environmentally hazard it posed), naturally occurring feed additive are urgently needed to replace and support the sustainable development in livestock production. The potential of Fossil shell flour as performance enhancer was investigated in this study. The major finding was that fossil shell flour increased growth performance, apparent nutrient digestibility, N retention and make minimum use of water in Dohne-Merino wethers. Hence it could be an alternative to chemical-based feed additive in livestock production. Abstract This study was carried out to determine the effect of varying levels of Fossil shell flour (FSF) supplementation on growth performance, water intake, digestibility and N retention in Dohne Merino sheep pursuant to establishing the optimum inclusion rate of this supplement in Dohne Merino diets. Sixteen Dohne-Merino wethers (18 ± 1.5 kg body weight) were used in a complete randomized design with four animals per treatment. Sheep were fed a basal diet without FSF addition (control, T1), or with the addition of FSF (2%, T2), (4%, T3) or (6%, T4) of the diet for 105 days. Treatment 3 (4% FSF) has the highest values of dry matter intake, total weight gain, N retention and for most of the apparent digestibility nutrients (CP, EE and Ash) compared to treatment T1, T2 and T4(p < 0.05). The urinary and fecal N excretion also significantly decreased in the FSF treated diets compared to the control (p < 0.05). Water intake values were highest in control and were significantly (p < 0.05) different from those in treatments 2 and 4, but not to treatment 3. It is concluded that 4% inclusion rate of FSF will give the best improvement on growth performance, diet digestibility and N retention of Dohne-Merino sheep. Also, the addition of FSF in the diets of sheep is a safe natural additive that can help to reduce environmental pollution by reducing fecal and urinary N excretion.

Abstract
The aim of this study was to determine the effect of exogenous butyrate on the structure and selected functions of the stomach in sheep. Eighteen rams (30.8 ± 2.1 kg; 12 to 15 mo of age) were allocated to the study and fed a diet for 14 d without (CTRL) or with sodium butyrate (BUT; 36 g/kg of offered DM). Neither DMI nor initial BW differed between treatments (P ≥ 0.61), but final BW was greater for BUT compared with CTRL (P = 0.03). Butyrate concentration in the reticuloruminal fluid and abomasal digesta was greater for BUT compared with CTRL (P ≤ 0.01), but total short-chain fatty acids (SCFA) concentration, as well as concentration of other SCFA, did not differ between treatments (P ≥ 0.07). Relative to BW, reticuloruminal tissue mass tended (P = 0.09) to be greater and omasal digesta was less (P = 0.02) for BUT compared with CTRL. Dietary butyrate did not affect ruminal papillae length, width, and density nor did it affect ruminal epithelium thickness (P ≥ 0.12) in the ventral sac of the rumen. However, the DM of ruminal epithelium (mg/cm2) tended (P = 0.06) to be greater for BUT compared with CTRL. Omasal and abomasal epithelium thicknesses were greater (P ≤ 0.05) for BUT compared with CTRL. Mitosis-to-apoptosis ratio in the abomasal epithelium was less for BUT compared with CTRL (P = 0.04). Finally, the mRNA expression of peptide transporter 1 in the omasal epithelium was less (P = 0.02) and mRNA expression of monocarboxylate transporter 1 in the abomasal epithelium tended (P = 0.07) to be greater for BUT compared with CTRL. It can be concluded that exogenous butyrate supplementation affected not only the rumen but also omasum and abomasum in sheep.

Abstract
Salinization of groundwater and soil is a prevalent global issue with serious consequences on animal health and production. The present study was conducted to investigate the capacity of Boer goats to adjust their salt intake from saline drinking water in a free-choice system. In total, 12 non-pregnant Boer goats aged between 1 and 8 years with an average BW of 46.4±8.3 kg were kept in individual pens for 4 weeks. In the control phase (1 week), only fresh water was supplied in five identical buckets for each pen. During the subsequent treatment phase (3 weeks), fresh water and four different concentrations (0.75, 1.0, 1.25 and 1.5% NaCl) of saline water were offered simultaneously in a free-choice system. The positions of the concentrations were changed daily at random. Cut hay and water were provided ad libitum, and a mineral supplement was allocated. Feed and water intake, mineral supplement intake, ambient temperature and relative humidity were recorded daily, whereas BW and body condition score were measured weekly. Dry matter intake, total water intake and total sodium intake were significantly (P<0.001) higher during the treatment phase. Body weight and body condition were not affected by saline water intake. Across the treatment phase, saline water consumption was significantly (P<0.001) lower in young (19.6±27.1 g/kg BW0.82 per day) than in adult goats (27.9±31.5 g/kg BW0.82 per day), indicating that young goats were more sensitive towards the saline water. All goats had a significant preference for fresh water (0% salt) over saline water. At the first offering of the simultaneous choice situation (week 2), animals did not differentiate between the salt concentration of 0.75% and 1.0%. However, with successive treatment (weeks 3 and 4), animals distinguished between saline water concentrations and preferred the 0.75% salt concentration. Salt concentrations of 1% to 1.5% were avoided. The total sodium intake of the goats ranged between 0.37 and 0.55 g /kg BW0.75 per day during the treatment phase, being 8- to 11-fold higher than the daily requirements of sodium for body maintenance. The results suggest that goats are able to differentiate between saline water concentrations and to adjust their sodium intake by quick adjustments in self-selection in a free-choice system. Compared with two-choice preference tests, the present free-choice situation allows evaluating changes in saline water acceptance with prolonged exposure.

Vascular Response to Graded Angiotensin II Infusion in Offspring Subjected to High-Salt Drinking Water during Pregnancy: The Effect of Blood Pressure, Heart Rate, Urine Output, Endothelial Permeability, and Gender. Int J Vasc Med 2014; 2014:876527.

Abstract
Introduction. Rennin-angiotensin system and salt diet play important roles in blood pressure control. We hypothesized that the high-salt intake during pregnancy influences the degree of angiotensin-dependent control of the blood pressure in adult offspring. Methods. Female Wistar rats in two groups (A and B) were subjected to drink tap and salt water, respectively, during pregnancy. The offspring were divided into four groups as male and female offspring from group A (groups 1 and 2) and from group B (groups 3 and 4). In anesthetized matured offspring mean arterial pressure (MAP), heart rate and urine output were measured in response to angiotensin II (AngII) (0-1000 ng/kg/min, iv) infusion. Results. An increase in MAP was detected in mothers with salt drinking water (P < 0.05). The body weight increased and kidney weight decreased significantly in male offspring from group 3 in comparison to group 1 (P < 0.05). MAP and urine volume in response to AngII infusion increased in group 3 (P < 0.05). These findings were not observed in female rats. Conclusion. Salt overloading during pregnancy had long-term effects on kidney weight and increased sex-dependent response to AngII infusion in offspring (adult) that may reveal the important role of diet during pregnancy in AngII receptors.

Abstract
Industries based on small ruminants are major contributors to world food supply but, in extensive grazing systems, reproductive technology is not directly relevant to most enterprises. More important is the need to respond to demand in high-profit export markets for products that are 'clean, green and ethical' (CGE). This combination of issues led to the concept of CGE management of reproduction that is based on scientific evidence but does not require complex technology. Nutrition is the major challenge because we are limited primarily to the grazing of forages and pastures, but responding to this challenge opens up opportunities-new forages can supply energy and protein whilst improving animal health and welfare, and reducing carbon emissions. A second major factor is the need for accurate coordination of nutritional inputs with reproductive events to ensure that the metabolic signals are appropriate. To control of the timing of reproduction, we need to move beyond simply managing the presence of the male and seek more precision. Our ultimate CGE package is thus based on manipulation of male socio-sexual signals as well as nutrition, in combination with greater use of ultrasound and birth-site management to prevent neonatal mortality. Finally, genetics is critical in the development of the CGE package.It would be difficult to incorporate the entire package in one hit-adaptations are needed to cover variations in genotype and the geographical and socio-economic environment, and some concepts need research and development. Therefore, we have suggested staged introduction of the elements of the package.CGE management can be simple and cost-effective, and improve productivity whilst safeguarding the future of the industries in society and the marketplace. Reproductive technology might not be used by many farmers but it will be an essential tool for realizing the vision because it underpins the acceleration of genetic progress in otherwise tardy grazing industries. Finally, we suggest that the socio-economic drivers and the scientific principles of CGE management are also applicable to smallholders in developing economies.
