摘要
[目的]研究不同芽孢杆菌复合制剂对断奶仔猪生长、腹泻和饲料消化率的影响。[方法]对照组饲喂基础日粮,试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别添加"凝结芽孢杆菌+巨大芽孢杆菌"、"酪酸菌+巨大芽孢杆菌"、"凝结芽孢杆菌+酪酸菌"和"凝结芽孢杆菌+酪酸菌+巨大芽孢杆菌"复合制剂,添加量0.2%,饲喂43 d,研究芽孢杆菌复合制剂对断奶仔猪生长、腹泻和饲料消化率的影响。[结果]各试验组均能显著提高平均日增重、增重率、特定生长率和蛋白质效率,显著降低摄食率和饲料系数(P<0.05),其中试验Ⅲ组和Ⅳ组又比试验Ⅰ组和Ⅱ组更显著(P<0.05)。各试验组均能显著降低腹泻率和粪便大肠杆菌数量,显著提高粪便乳酸菌数量(P<0.05),其中试验Ⅲ组和Ⅳ组在降低大肠杆菌上比试验Ⅰ组和Ⅱ组更显著(P<0.05)。各试验组均能显著提高粗蛋白和粗纤维的消化率(P<0.05),但对粗脂肪、粗灰分和磷的消化吸收无影响(P>0.05),其中试验Ⅳ组的粗蛋白消化率最高(P<0.05)。[结论]试验Ⅳ组采用的复合制剂养殖效果最为理想,经济效益最为显著,具有一定的推广应用价值。
[Objective] This paper was conducted to investigate the effects of a diet supplemented various Bacillus complex preparation on the growth performance,diarrhea and feed digestibility in weaned piglets. [Method]The control group was fed a basal diet. The experiment groupⅠ,Ⅱ,Ⅲ,Ⅳ were supplemented＂Bacillus coagulans ＋ Bacillus megaterium＂,＂Clostridium butyricun ＋ Bacillus megaterium＂,＂Bacillus coagulans ＋ Clostridium butyricun＂and ＂Bacillus coagulans ＋ Clostridium butyricun ＋ Bacillus megaterium＂complex preparation respectively. The supplemented content was 0. 2%,and the feeding time was 43 days. Effects of different Bacillus complex preparation on weaned piglets growth,diarrhea and feed digestibility were studied. [Result] All of the experiment groups significantly increased the average daily gain,weight gain rate,specific growth rate and protein efficiency ratio（ P〈0. 05）; significantly decreased the feeding rate and the feed coefficient ratio（ P〈0. 05）; and the experiment group Ⅲ and Ⅳ appeared more significantly than the experiment group Ⅰ and Ⅱ（ P〈0. 05）.All of the experiment groups significantly decreased the diarrhea rate and the fecal Escherichia coli amount（ P〈0. 05）,significantly increased the fecal Lactic acid bacteria amount（ P〈0. 05）,and the experiment group Ⅲ and Ⅳ appeared more significantly than the experiment groupⅠ and Ⅱ in the reduce of fecal Escherichia coli amount（ P〈0. 05）. All of the experiment groups significantly increased the digestion rate of crude protein and crude fiber（ P〈0. 05）,but had no effects on the digestion of crude fat,crude ash and total phosphorus（ P〈0. 05）,and the crude protein digestion rate of experiment group Ⅳwas the highest（ P〈0. 05）. [Conclusion]The complex preparation used in experiment group Ⅳhad the best breeding effect,the highest economic benefit,and it had the value of extension and application.
