Premix material special for by-pass cow and preparation method thereof

Abstract

The invention relates to a special premix compound for rumen bypass cows and a preparation method thereof. The formula of the premix compound is that every kilogram contains 100 to 150g of lysine, 10 to 20g of methionine, 15 to 30g of betaine, 100 to 250mg of folic acid, 15 to 30g of choline, 50 to 100g of phytase, 50 to 100g of non-starch polysaccharide enzyme and hydrogenated palm powder. The preparation method is that firstly a stainless steel stirrer is used for heating water at 50 to 60 DEG C and dissolving the hydrogenated palm powder; other materials are added and mixed evenly; then the materials are placed to be cooled. The special premix compound for rumen bypass cows can increase milk yield, improve milk fat percentage and milk protein, reduce the dosage of calcium hydrogen phosphate, eliminate anti-nutritional factors, widen feed sources and can improve the health of cows.

Description

technical field [0001] The invention belongs to the field of dairy cow feed, and in particular relates to a special premix for rumen-passed dairy cows and a preparation method thereof. Background technique [0002] When the daily yield of dairy cows exceeds 30kg, the dietary combination must consider amino acids, especially the first and second limiting amino acids. Methionine and lysine may be the first and second limiting amino acids for dairy cows. Add methionine directly to the diet of dairy cows and lysine, most of which are degraded by rumen microorganisms and cannot achieve the supplementary effect, so they must be added in the form of passing through the rumen. At present, rumen-passing lysine products have not been reported, and folic acid, choline, betaine and methionine participate in formazan They have the effect of saving methionine and increasing the yield per unit area, but folic acid, choline, and betaine are also easily degraded by rumen microorganisms, and ...

Problems solved by technology

[0002] When the daily yield of dairy cows exceeds 30kg, the dietary combination must consider amino acids, especially the first and second limiting amino acids. Methionine and lysine may be the first and second limiting amino acids for dairy cows. Add methionine directly to the diet of dairy cows and lysine, most of which are degraded by rumen microorganisms and cannot achieve the supplementary effect, so they must be added in the form of passing through the rumen. At present, rumen-passing lysine products have not been reported, and folic acid, choline, betaine and methionine participate in formazan They have the effect of saving methionine and increasing the yield per unit area, but folic acid, choline, and betaine are also easily degraded by rumen microorganisms, and rumen technology must be used. Dairy cows use more by-products in diets, such as bran, rice bran, barley, Wheat grains, etc., they contain more anti-nutritional factors such as non-starch polysaccharides and phytic acid. Through rumen-passing technology, the enzymes that eliminate anti-nutritional factors can be released at fixed points in the intestinal tract, improve feed digestibility, and reduce the use of calcium hydrogen phosphate. Currently There is no such report at home and abroad
