膳食益生菌补充剂对饲喂基于三线干草干草的日粮母羊摄入和生产性能的影响
摘要
The present study was carried out to evaluate the effects of probiotics on intake, performance, rumen fermentation and blood metabolites of Barki ewes fed Atriplex hay based diet. Thirty pregnant Barki ewes with an average initial body weight (BW) of 45.5 ± 0.98 kg, were blocked according to lambing date and BW into three experimental groups. The treatments were: (1) control diet, (2) control diet + 2 g Saccharomyces cerevisiae (2 × 1010 CFU) per day and (3) control diet + 2 g Bacillus subtilis (1.0 × 1011 CFU/kg) and Lactobacillus casei (1 × 1010 CFU/kg) per day. Probiotics inclusion increased dry matter, organic matter, crude protein and neutral detergent fiber intakes (P < 0.05) but did not affect body weight, milk yield, milk composition or efficiency (milk/dry matter intake). The bacteria diet increased average daily weight gain of lambs (P < 0.05) compared to the yeast and control diets. Compared with the control, the probiotic diets increased (P < 0.05) ruminal ammonia-N concentration. The pH and total volatile fatty acids concentration were not influenced by probiotic supplementation. Blood urea nitrogen was increased (P < 0.05) and total lipids and triglycerides were decreased (P < 0.05) with probiotics supplementation. All the other blood parameters were not affected. The present study demonstrated that supplementing ewes fed Atriplex hay based diets with probiotic bacteria resulted in higher weaning weight, average daily weight gain and improved health status in lambs.

本研究旨在评估益生菌对以Atriplex干草为基础的日粮摄入Barki母羊的摄入量,生产性能,瘤胃发酵和血液代谢产物的影响。根据产羔日期和体重,将三十只平均体重(BW)为45.5±0.98 kg的怀孕巴尔基母羊分为三个实验组。治疗方法为:(1)控制饮食,(2)控制饮食+ 2 g酿酒酵母(2×10 10 CFU)/天,(3)控制饮食+ 2 g枯草芽孢杆菌(1.0×每天10 11 CFU / kg)和干酪乳杆菌(1×10 10 CFU / kg)。益生菌的添加增加了干物质,有机物质,粗蛋白和中性洗涤剂纤维的摄入量(P <0.05),但不影响体重,牛奶产量,牛奶成分或效率(牛奶/干物质摄入量)。与酵母和对照饮食相比,细菌饮食增加了羔羊的平均日增重(P <0.05)。与对照组相比,益生菌饮食增加了瘤胃氨氮浓度(P <0.05)。 pH和总挥发性脂肪酸浓度不受益生菌补充的影响。补充益生菌后,血尿素氮增加(P <0.05),总脂质和甘油三酸酯减少(P <0.05)。所有其他血液参数均未受影响。本研究表明,以益生菌细菌补充饲喂以三线干草为基础的日粮的母羊可导致较高的断奶体重,平均日增重和改善羔羊的健康状况。
