枯草芽孢杆菌微生态预混料饲喂能繁母羊的效果对比试验

Comparative Experiment on Feeding Fertile Ewes with Bacillus Subtilis Microecological Premix

本试验主要利用枯草芽孢杆菌微生态预混料添加在精料中饲喂能繁母羊,掌握能繁母羊的采食量、健康水平、产羔数量以及羔羊成活率、治疗用药等情况。结果表明:枯草芽孢杆菌微生态预混料添加在精料中,能够有效改善母羊肠道微生物环境,有效替代抗菌类药物,提高母羊整体健康状态。自配精料中添加枯草芽孢杆菌微生态预混料1%、2%饲喂能繁母羊,其精神状态、产羔数、初生重、成活率、治疗用药费等方面效果明显差异显著;与添加0.5%枯草芽孢杆菌微生态预混料相比,饲喂效果不明显,差异不显著。因此,自配精料中添加枯草芽孢杆菌微生态预混料,添加量为1%,其效果最佳。

In this experiment,the Bacillus subtilis microecological premix was added to the concentrate to feed the breeding ewes,and the feed intake,health level,lambing number,lamb survival rate,and therapeutic drugs of the breeding ewes were mastered.The results showed that the addition of Bacillus subtilis microecological premix to the concentrate can effectively improve the intestinal microbial environment of ewes,effectively replace antibacterial drugs and improve the overall health of ewes.Adding 1%and 2%of Bacillus subtilis microecological premix to self-prepared concentrate to feed fertile ewes,the effect is remarkable in terms of mental state,number of lambs,birth weight,survival rate,and treatment fee.Adding 0.5%feeding,the effect is not significant.Therefore,the Bacillus subtilis microecological premix is added to the self-prepared concentrate,and the addition amount is 1%,and the effect is the best.
