【摘要】：将32头28日龄断奶(杜×长×大)健康仔猪平均分成4个处理组:对照组(组合抗生素组)、试验组1(凝结芽孢杆菌组)、试验组2(枯草芽孢杆菌组)、试验组3(同时添加凝结芽孢杆菌及枯草芽孢杆菌组),研究凝结芽孢杆菌与枯草芽孢杆菌组合使用,对28~56 d断奶仔猪生长性能的影响。试验结果显示:平均日增重指标:试验组1和试验组3差异不显著(P0.05),均显著高于(P0.05)对照组和试验组2。料肉比指标,试验组1显著低于(P0.05)其他三个处理组。试验组1仔猪对饲料的干物质表观消化率与对照组差异不显著(P0.05),均高于(P0.05)试验组2。试验结果表明:仔猪商业饲料在组合使用多种常规饲用抗生素的基础上,单一添加饲用凝结芽孢杆菌能够进一步改善断奶仔猪的生产性能;然而,单一添加枯草芽孢杆菌、或凝结芽孢杆菌与枯草芽孢杆菌组合使用,均没有获得进一步改善仔猪生长性能的显著正效应。
[Abstract]:32 28 day weaned healthy piglets were divided into four groups: control group (combined antibiotic group), experimental group 1 (Bacillus coagulans group), test group 2 (Bacillus subtilis group), and test group 3 (simultaneously). Adding Bacillus coagulans and Bacillus subtilis) to study the combination of Bacillus coagulans and Bacillus subtilis. Effect on growth performance of 2856-day weaned piglets. The results showed that the average daily gain index: there was no significant difference between test group 1 and test group 3 (P0.05), which were significantly higher than that of control group and test group (P0.05). The index of feed to meat ratio in the test group 1 was significantly lower than that in the other three treatment groups (P0.05). The apparent digestibility of dry matter of piglets in test group 1 was not significantly different from that in control group (P0.05), but was higher than that in test group (P0.05). The results showed that the commercial feed of piglets could further improve the performance of weaning piglets by adding Bacillus coagulans on the basis of combination of various conventional feed antibiotics, but only adding Bacillus subtilis was added to the piglets. The combination of Bacillus coagulans and Bacillus subtilis had no significant positive effect on further improving the growth performance of piglets.
