Example Embodiment

[0032] Example 1:

[0033] The weight percentages of each component of the feed additive are: expanded soybean 35wt%, urea 5wt%: soybean protein concentrate 5wt%, sclerotia 25wt%, pannus 20wt%, slow release agent 5wt%, and Aspergillus awamori culture 5wt% .

[0034] Said sclerotia vulgaris is solid fermentation bacteria and fungal substance;

[0035] The compact bacteria are fermenting mycelium;

[0036] The sustained-release agent is mainly composed of ferrous sulfate, copper sulfate, calcium carbonate, and sodium metabisulfite;

[0037] The composition ratio of the sustained-release agent according to weight percentages is as follows: ferrous sulfate 13%, copper sulfate 17%, calcium carbonate 62%, and sodium metabisulfite 8%.

[0038] The preparation method is as follows:

[0039] Crush the above proportions of urea, Aspergillus awamori culture, soybean protein concentrate, sclerotia, compact bacteria, and slow-release agent to obtain materials with a length or particle size of less th...

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 ...
