Description

Technical Field

[0001] The invention relates to the technical field of fattening sheep feed, in particular to a straw probiotic feed. Background Art

[0002] Straw is a widely produced by-product in agricultural production, mainly including corn straw, wheat straw, rice straw, etc. These straws are rich in various organic substances such as cellulose, hemicellulose, lignin, etc. As a feed raw material for ruminants, they can provide important nutrients for them in some cases. However, straw contains a large amount of macromolecular substances such as cellulose, which are difficult to be directly and effectively utilized by ruminants such as sheep, limiting the widespread application of straw in animal husbandry. Traditionally, ruminants can digest part of the cellulose through their unique gastrointestinal system (including the rumen), but their digestion capacity and conversion efficiency are much lower than those of concentrated feeds, and incomplete digestion of excessive cellulose may also cause intestinal discomfort or malnutrition.

[0003] In the prior art, although there are certain methods to improve the utilization efficiency of straw, there are still problems such as complex processing methods, high costs and serious environmental pollution.

[0004] In the field of animal husbandry, in order to improve the efficiency of breeding, a large amount of concentrated feed, such as corn, soybean meal, wheat bran, etc., is usually added. These concentrated feeds are rich in energy and protein, which are the key to the rapid weight gain of fattened sheep. However, the cost of these concentrated feeds is high, which directly affects the economic efficiency of mutton production. Especially in small-scale and medium-sized farms, feed costs usually account for the main part of breeding costs. Therefore, how to reduce feed costs and improve the utilization rate of straw has become an urgent problem to be solved in the industry.

[0005] In addition, large amounts of antibiotics are used in traditional feed, affecting the quality and safety of mutton.

[0006] Therefore, an innovative and environmentally friendly straw resource utilization technology is urgently needed. Summary of the invention

[0007] The purpose of the present invention is to provide a straw probiotic feed, which aims to improve the utilization efficiency of straw by ruminants by selecting and optimizing probiotic strains and combining the fermentation conversion of straw, thereby reducing feed costs, improving mutton production efficiency, and promoting the resource utilization of straw and the development of green breeding technology to solve the technical problems raised in the background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions: a straw probiotic feed, comprising at least straw, concentrated feed, soybean meal, bran, a probiotic group and a nutrient addition group;
