Problems solved by technology

But the premise is that under the condition of severe dietary protein deficiency in dairy cows, increasing the dietary protein level can improve the digestibility and feed intake of dairy cows, so the milk production will also increase, resulting in an increase in milk protein content

Abstract

The invention discloses a feed additive, belongs to the field of feeds, and in particular relates to a dairy cattle feed product. Urea, soy protein concentrate powder, schizophyllum commune, shoestring fungus, sustained-release agent and aspergillus awamori culture compound sustained-release agent are crushed, mixed uniformly and extruded by using a feed extruder, and the extruded powder is mixedwith extruded soybean. When the obtained feed product is used for raising dairy cattle, the energy of the dairy cattle at the lactation stage can be balanced, the daily milk yield and the peak retention are improved, the conception rate of the dairy cattle is improved, and the lactation peak is prolonged.

Description

Technical field: [0001] The invention belongs to the field of feed, in particular to dairy cow feed products. Background technique: [0002] Protein is the main raw material for milk protein synthesis and one of the main limiting nutrients in the diet of lactating dairy cows. In the rumen, protein is degraded by rumen microorganisms and synthesizes microbial protein, and rumen undegraded protein and endogenous protein enter the small intestine with rumen chyme to form intestinal metabolic protein, which is digested and absorbed in the small intestine and synthesized milk protein in the mammary gland. However, the protein synthesis efficiency of rumen microorganisms is not high, and the amino acid composition is unbalanced, which affects the synthesis of milk protein. Therefore, protein deficiency in the diet leads to a decrease in milk protein concentration, while protein supplementation can significantly increase milk protein concentration. The study found that for every ...
