Special compound bacterium preparation for hybrid mutton sheep and preparation method of special compound bacterium preparation

Abstract

The invention provides a special compound bacterium preparation for hybrid mutton sheep. The compound bacterium preparation comprises the following microorganisms of bacillus subtilis, bacillus amyloliquefaciens, lactococcus lactis, bifidobacterium bifidum, lactobacillus acidophilus, candida utilis, saccharomyces cerevisiae and aspergillus oryzae. The special compound bacterium preparation for hybrid mutton sheep is non-toxic, free from drug tolerance, and free from residues. The quality of F1 generation hybrid mutton sheep of pure blackhead Dorper sheep and small-tailed han sheep is notably improved, and the dressing percentage and the body meat yield are increased.

Description

technical field [0001] The invention belongs to a microecological preparation for hybrid mutton sheep, and in particular relates to a special compound bacteria preparation for hybrid mutton sheep and a preparation method thereof. Background technique [0002] The genetics of Dorper sheep are very stable, no matter purebred or improved offspring, they all show excellent production performance and adaptability, especially the meat production performance, the fat distribution in the meat is even, and it is a high-quality carcass. Both imported and domestically produced sheep breeds for meat are incomparable. Well-grown lambs have excellent carcass quality, both in shape and in fat distribution. At present, white-headed breeds are mainly imported in China, and black-headed purebreds are rarely introduced. We introduce purebred black-headed Dorper sheep embryos from Australia, and use small-tailed Han sheep and Hu sheep as recipient ewes to obtain purebreds through embryo transf...

Problems solved by technology

However, due to the rapid growth of this kind of hybrid mutton sheep, the requirements for lamb feeding conditions are high, and the intestinal flora is easily unbalanced, which will lead to intestinal diseases of lambs and reduce the feed utilization rate.

In the prior art, there are also microbial preparations for conditioning the intestinal flora of mutton sheep, but the effect is not ideal when used in the F1 generation of mutton sheep crossed between purebred black-headed Dorper sheep and small-tailed Han sheep

[0004] The existing technology has the following technical defects: it is used for the F1 generation of mutton sheep crossed between purebred black-headed Dorper sheep and small-tailed Han sheep, and the lamb disease prevention effect is poor, and the lamb intestinal flora cannot be well adjusted, resulting in low lamb feed utilization. The above-mentioned hybrid mutton sheep are of poor quality
