Zheng W, Duan H, Cao L, Mao S, Shen J. Acid-base properties of non-protein nitrogen affect nutrients intake, rumen fermentation and antioxidant capacity of fattening Hu sheep. Front Vet Sci 2024; 11:1381871. [PMID: 38596467 PMCID: PMC11002212 DOI: 10.3389/fvets.2024.1381871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Accepted: 03/14/2024] [Indexed: 04/11/2024] Open
Abstract
This study conducted a comparison of the effects of non-protein nitrogen with different acid-base properties on feed intake, rumen fermentation, nutrient digestion and antioxidant capacity in fattening Hu sheep. Sixteen fattening male sheep (31.43 ± 2.41 kg) with permanent rumen cannulas were randomly assigned to two dietary treatments: 1% urea and 1.78% ammonium chloride (NH4Cl, AC). A 42 days experimental period was conducted, with 14 days for adaptation and 28 days for treatment. Daily feed intake was recorded and various samples including feed, feces, rumen fluid, and blood were collected at different time points during the final week. The results indicated that the urea group had significantly higher dry matter intake, average daily gain, and gain efficiency in comparison to the AC group (p < 0.01). There was no difference in rumen pH and concentration of ammonia nitrogen between different groups (p > 0.05), but the rumen pH of urea group was higher than that of the AC group at 1 and 3 h after feeding (p < 0.05). The urea group exhibited higher concentrations of total volatile fatty acids (VFA) and individual VFAs compared to the AC group at all-time points (p < 0.01). Compared to the urea group, the intake of all nutrients decreased in the AC group (p < 0.01), but the digestibility of dry matter and organic matter increased significantly (p < 0.01), and the digestibility of CP had an increasing trend (p = 0.06) in the AC group. Additionally, the urea group had lower levels of serum glucagon-like peptide-1, peptide YY, Cl, total protein and globulin than the AC group (p < 0.05). The overall levels of HCO3-, superoxide dismutase, glutathione peroxidase, catalase, albumin/globulin, blood urea nitrogen and total cholesterol in the urea group increased significantly compared to the AC group (p < 0.05). It was concluded that adding urea to the high-concentrate diet resulted in increased rumen pH and improved rumen fermentation and growth performance in fattening sheep compared to NH4Cl addition. Furthermore, urea addition improved sheep's antioxidant capacity and maintained their acid-base balance more effectively as compared to NH4Cl.

Abstract
Environmental heat stress creates a detriment to the welfare and performance in broiler chickens. While there are some dietary mineral and vitamin supplements that mitigate this condition, a rapid, plasma-based detection method would improve management response and broaden the scientific understanding of heat stress. A total of 960 broilers were used to determine the effect of heat stress and dietary electrolyte balance on blood biochemistry. Sex sorted chicks were allocated to 48 pens with 20 chicks per pen creating 6 treatments (3 diets x 2 house environments) with eight replicates and fed one of three dietary treatments: a control containing primarily sodium chloride (NaCl), a heat stress formulation containing bicarbonate (NaHCO3), or heat stress fortified with 200 ppm vitamin C and E (NaHCO3 Fortified). Birds were housed in two different temperature-controlled environments either a thermoneutral (Control) or heat stressed (Heat Stress) environment. At day 28, 35 and 42 venous blood was collected and analyzed using rapid detection methods followed by post-mortem veterinary evaluations. Performance was measured at weekly intervals. Mortality was significantly higher in broilers exposed to heat stress as compared to thermoneutral, while broilers that received dietary sodium chloride also had higher mortality than bicarbonate fed birds. Heat stress significantly impacted potassium, hematocrit, uric acid, total protein, globulin, hematocrit, lymphocytes, sodium, and glucose. This study demonstrates that blood biochemistry of broiler chickens is influenced by dietary intervention and changing environmental conditions. This pattern suggests a blood biomarker footprint of sub-optimal nutrition or poor environmental conditions that may provide valuable information into physiological changes in response to dietary electrolytes, vitamins, and heat stress. Furthermore, this footprint may potentiate the development of diagnostic tools, combining biomarkers to determine nutrition and health status of individual broiler flocks, for nutritionists, veterinarians, and live production managers to manage flocks for environmental, humane, and productive purposes.

Abstract
The increasing demand of wood shavings (WS) and sawdust (SD) by other industries and growing concerns of potential chemical contaminants from wood products have amplified research interest in alternative bedding materials for commercial poultry. Several alternative materials-corn cob (CC), straws (ST) and hays (HA), sand (SA), shredded papers (SP), rice hulls (RH), peanut hulls (PH), and gypsum (CaSO4.2H2O2)-can replace conventional ones in poultry houses, depending on availability, cost, and ability to absorb and adsorb moisture and provide the birds enough room to exhibit their natural behaviors. Alternative materials hold a brighter future as bedding materials, but more studies about their physicochemical properties and litter management practices for optimum poultry welfare are recommended.

The effect of different dietary levels of sodium and chloride on performance, blood parameters and excreta quality in goslings at 29 to 70 days of age. J Anim Physiol Anim Nutr (Berl) 2021; 106:98-109. [PMID: 33844875 DOI: 10.1111/jpn.13541] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 03/03/2021] [Accepted: 03/04/2021] [Indexed: 01/09/2023]
Abstract
The purpose of this study was to ascertain the appropriate levels of dietary sodium (Na+ ) and chloride (Cl- ) for 29- to 70-day-old goslings and to investigate the effects of different levels of Na+ and Cl- on the growth performance, water consumption, blood parameters and excreta quality of goslings to provide a reference for the healthy production of goslings. In Experiment 1, a total of 432 29-day-old male Jiangnan White goslings were randomly allotted to nine treatments according to a 3 × 3 factorial design, with six pens containing eight birds per treatment. The goslings were fed diets with three concentrations of Na+ (0.10%, 0.15% and 0.20%) and three concentrations of Cl- (0.15%, 0.20% and 0.25%). The experimental period was 42 days. In Experiment 2, a total of 24 70-day-old Jiangnan White goslings were selected for four treatments (0.10% Na+ × 0.15% Cl- ; 0.10% Na+ × 0.25% Cl- ; 0.20% Na+ × 0.15% Cl- and 0.20% Na+ × 0.25% Cl- ) and housed separately in metabolic cages. The faeces were collected for 3 consecutive days. In Experiment 1, the average daily feed intake (ADFI), average daily gain (ADG) and feed/gain (F/G) ratio of goslings were unaffected by the treatments. However, low levels of Na+ and Cl- significantly reduced the water consumption of goslings in the later growth period (p < 0.05). The average water consumption of goslings fed with 0.10% Na+ × 0.15% Cl- was significantly lower than that of the goslings fed with 0.20% Na+ × 0.25% Cl- (56 days, 1304.2 ml vs. 1471.7 ml; 63 days, 1452.8 ml vs. 1610.8 ml; 70 days, 1540.0 ml vs. 1775.4 ml; p < 0.05). The interaction between Na+ and Cl- (Na+ × Cl- ) had a significant impact on the blood haemoglobin (HGB) and haematocrit (HCT) levels in the goslings (p < 0.05). HGB increased linearly with increasing levels of Na+ . HGB and HCT first increased and then decreased with increasing levels of Cl- . In Experiment 2, Na+ and Cl- levels had significant effects on the excreta moisture content (p < 0.05). Goslings fed with 0.10% Na+ × 0.15% Cl- had a low moisture content of 5.58% compared to the goslings fed with 0.20% Na+ × 0.25% Cl- (87.51% vs. 93.09%; p < 0.05). The levels of dietary Na+ had a significant effect on the retention ratio of Na (p < 0.05), with the value for the 0.20% Na+ group being significantly higher than that for the 0.10% Na+ group (p < 0.05). In summary, different levels of Na+ and Cl- did not affect the growth of goslings. To reduce the water consumption and moisture content of excreta, the Na+ and Cl- levels in the diet can be as low as 0.10% and 0.15%, respectively.

Abstract
Globally, the poultry industry is gaining significant importance among the agricultural and its allied sectors. However, heat stress was found to negatively affect the poultry production particularly in the tropical regions. This review is therefore an attempt to generate information pertaining to the impacts of heat stress on poultry production and its amelioration. Heat stress reduces the growth, reproductive performance, and egg production in poultry birds. The reduction in productive potential of poultry birds on exposure to heat stress may be attributed to the deviation of energy resources from production to adaptation pathway. There are different approaches pertaining to relieving the adverse impacts of heat stress on poultry production. These approaches can be broadly categorized under genetic, management, and nutritional strategies. These approaches may reduce the negative effects of heat stress and enhance the productive performance of poultry birds. The management strategies include appropriate shelter design, providing shade, using sprinklers, implementing cooling devices, and using fans and ventilation systems. The recommended floor space for mature birds weighing 1.7 kg is 0.06 m2/bird while it is 0.13 m2/bird for the birds weighing 3.5 kg with 27.8 kg/m2 bird density in either case. The nutritional interventions comprise ration balancing and providing essential micronutrients to improve the productive and reproductive performance in poultry birds. Fat, antioxidants, yeast, and electrolyte supplementations are some of the most commonly used nutritional strategies to ensure optimum production in the poultry industry. Furthermore, providing adequate water supply and disease surveillance measures may help to ensure optimum meat and egg production in the birds. The advanced biotechnological tools may aid to identify suitable genetic markers in poultry birds which might help in developing new strains of higher thermo-tolerance by designing suitable breeding program involving marker-assisted selection. These strategies may help to optimize and sustain poultry production in the changing climate scenario.

Abstract
The effects of dietary electrolyte balance (DEB) and electrolyte-betaine (El-Be) supplements on heat-stressed broiler performance, acid-base balance and water retention were evaluated during the period 31-40 d of age in a 2 × 3 factorial arrangement of treatments. A total of 240 broilers were assigned to 6 treatment groups each with 8 replicates of 5 birds per cage and were exposed to cyclic high temperature (32 - 24 ± 1°C). Birds were provided with diets having DEB of either 180 or 220 mEq/kg. El-Be supplements were either added to the diet, water or not added to either of them to complete the array of 6 treatment groups. An additional 80 birds were kept at thermoneutral temperature (20 ± 1°C) and were provided with tap water and diets with DEB of either 180 or 220 mEq/kg to serve as negative controls. Exposure to high temperature depressed growth performance, increased rectal temperature and decreased potassium (K(+)) retention. In high-temperature room, birds fed on diets with DEB of 220 mEq/kg tended to increase BW from 35-40 d of age. However, at thermoneutral temperature, broilers fed on diets with DEB of 220 mEq/kg increased K(+) retention. Adding El-Be supplements in feed or water improved feed conversion ratio (FCR), enhanced water consumption and increased K(+) and sodium (Na(+)) retention. Interactions between DEB and El-Be supplements tended to affect body weight gain and FCR during the periods 35-40 and 31-40 d of age, respectively. It is suggested that when using a diet with DEB of 180 mEq/kg, adding the El-Be supplements in drinking water was more beneficial than in feed. Adding the supplements in feed or water was equally useful when using DEB of 220 mEq/kg.

Growth Performance, Carcass Characteristics and Plasma Mineral Chemistry as Affected by Dietary Chloride and Chloride Salts Fed to Broiler Chickens Reared under Phase Feeding System. ASIAN-AUSTRALASIAN JOURNAL OF ANIMAL SCIENCES 2014; 26:845-55. [PMID: 25049859 PMCID: PMC4093254 DOI: 10.5713/ajas.2012.12664] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/29/2012] [Revised: 03/06/2013] [Accepted: 01/29/2013] [Indexed: 11/29/2022]
Abstract
Requirements of dietary chloride (dCl) and chloride salts were determined by using 4×2 factorial arrangement under four phase feeding program. Four levels (0.31, 0.45, 0.59 and 0.73%) and two sources (NH4Cl and CaCl2) of the dCl were allocated to 1,472 chicks in eight dietary treatments in which each treatment was replicated four times with 46 birds per replicate. The four phase feeding program was comprised of four dietary phases: Prestarter (d 1 to 10), Starter (d 11 to 20), Grower (d 21 to 33) and Finisher (d 34 to 42); and diets were separately prepared for each phase. The cations, anions, pH, dissolved oxygen (DO), temperature, electrical conductivity (EC), total dissolved solids (TDS) and salinity were analyzed in drinking water and were not affected by dietary treatments. BW gain (BWG; p≤0.009) and feed:gain (FG; p≤0.03) were improved in CaCl2 supplemented diets during d 1 to 10. The maximum response of BWG and FG was observed at 0.38% and 0.42% dCl, respectively, for d 34 to 42. However, the level of dCl for BWG during d 21 to 33 (p≤0.04) and d 34 to 42 (p≤0.009) was optimized at 0.60% and 0.42%, respectively. The level of dCl for optimized feed intake (FI; p≤0.006), FG (p≤0.007) and litter moisture (LM; p≤0.001) was observed at 0.60%, 0.38% and 0.73%, respectively, for d 1 to 42. Water intake (DWI) was not affected by increasing dCl supplementation (p>0.05); however, the ratio between DWI and FI (DWI:FI) was found highest at 0.73% dCl during d 1 to 10 (p≤0.05) and d 21 to 33 (p≤0.009). Except for d 34 to 42 (p≤0.006), the increasing level of dCl did not result in a significant difference in mortality during any phase. Blood pH and glucose, and breast and thigh weights (percentage of dressed weight) were improved while dressing percentage (DP) and gastrointestinal health were exacerbated with NH4Cl as compared to CaCl2 supplemented diets (p≤0.001). Higher plasma Na+ and HCO3− and lower Cl− and Ca++ were observed in NH4Cl supplemented diets (p≤0.001). Increasing supplementation of dCl increased plasma Cl− (p≤0.04; quadratically) and linearly reduced plasma K+ (p≤0.001), Ca++ (p≤0.003), HCO3− (p≤0.001), and Na+ (p≤0.001; quadratically). Consequently, higher requirements of dietary chloride are suggested for feed intake; nevertheless, lower levels of dietary chloride are sufficient to support optimal BWG and FG with increasing age. The NH4Cl supplemented diets ameliorate breast and thigh meat yield along with overall energy balance (glucose).

Abstract
The effect of sodium and sodium salts on carcass and body organ characteristics of broilers under a four phase feeding program were investigated. A basal diet (0.08% dNa with NaCl) was formulated and one of two sources of dNa (NaHCO3 and Na2SO4) were supplemented to obtain four different percentages of dNa (0.17, 0.26, 0.35, and 0.44%) for each treatment. There was a linear decrease in dressing percentage (DP) with source × level interaction (p ≤ 0.001), while there was a linear increase in breast yield and thigh yield with increasing dNa supplementation (p ≤ 0.001). Chicks fed 0.35% NaHCO3 and 0.44% dNa Na2SO4 supplemental salts had lower abdominal fat (p ≤ 0.04). Chicks that received increasing levels of dNa (from 0.17 to 0.44%) showed increasing gizzard weight (p ≤ 0.002) and decreasing spleen weight (p ≤ 0.02). When both salts were supplemented at 0.26% dNa, the chicks showed their lowest bursa weight (p ≤ 0.001). Consequently, chicks at higher dNa showed an increase in breast and thigh meat yield, and increasing capacity of their digestive organ. The higher levels of dNa should be tested with other cations and anions to fully understand acid base homoeostasis.

Abstract
This study was conducted to assess the effect of different total dissolved solids (TDS) levels (265, 2610, 3154, and 3448 ppm) in drinking water obtained from natural sources on the performance and immune response of broilers against sheep red blood cells (SRBC) and Newcastle disease (ND) vaccine under hot, arid environmental conditions. Each water treatment was given to a group of 100 Ross 308 broiler chicks. Each group of chicks was divided into five replicates in a cage house system. All chicks were injected with SRBC at 8 days of age when drinking water treatments started. Water intake increased significantly with the increase of TDS level. Feed efficiency and bodyweight gain were affected negatively only under the highest TDS level (3448 ppm). The highest weight gain was observed at the 2610 ppm TDS level. Plasma total protein and albumin concentration showed a significant increase at the two highest levels of TDS (3154 and 3448 ppm) in drinking water. Heterophil/lymphocyte ratio was significantly elevated by the increase of the TDS level in drinking water. At 21 days of age the chicks consuming drinking water with TDS of 2610 and 265 ppm recorded a significantly higher (P < 0.05) ND antibody titer than the other two groups. At 28 and 35 days of age chicks consuming drinking water containing 2610 ppm of TDS recorded a significantly higher (P < 0.05) ND antibody titer than the group consuming water containing TDS of 265 ppm. Higher levels of antibody titer against SRBC were recorded in birds consuming drinking water with TDS of 2610 and 265 ppm at 7 and 10 days post injection than the other two groups. However, at 10 days post injection birds consuming drinking water with 2610 ppm TDS recorded higher antibody titer than birds consuming 265 ppm TDS drinking water. In conclusion, 265 and 2610 ppm of TDS in drinking water did not negatively affect broiler productive performance, while levels of 3154 and 3448 ppm may negatively affect broiler growth. The study suggests that a TDS level of 2610 ppm has a better effect on broiler performance, in terms of weight gain and immune response in hot and arid environmental conditions, compared with a TDS level of 265-ppm level.
