Substitute for vegetable protein in milk replacer or starter of ruminants and application of substitute

Abstract

The invention relates to a substitute for vegetable protein in a milk replacer or starter of ruminants and application of the substitute to preparation of the milk replacer or starter. The substitute contains pea protein isolate and rice protein concentrate. The invention further provides the substitute to preparation of a milk replacer or starter used in the early weaning process of calves, wherein the milk replacer or starter comprises 20-46% of the substitute. The milk replacer or starter is prepared from the following components: pea protein isolate, rice protein concentrate and pea dietary fiber. The milk replacer or starter provided by the invention is high in digestibility and is suitable for sucking calves with rumens developing fast. An early weaning mode is established; ruminant experiments show that the calves can be weaned when being 42 days, which is two weeks ahead of the present situation of weaning at the age of eight weeks in China, so that the labor input of liquid feeding is reduced.

Description

technical field [0001] The invention relates to the field of ruminant animal feed in animal husbandry, in particular to a substitute for plant protein in ruminant milk substitutes or starter feeds and calf milk substitutes and starter feeds containing the substitutes with high nutritional components, which can improve the rumen development of calves and achieve The purpose of early weaning reduces the cost of breeding. Background technique [0002] Calf breeding is the first step in dairy cow production, and strengthening calf breeding is an important link to improve the quality of the herd and create a high-yield herd. Soy products have been the main protein source in calf diets. The amino acid composition of soybean protein is similar to that of milk protein. Except for the slightly lower content of methionine, the content of other essential amino acids is relatively rich, and the amino acid composition is close to that of animals. The nutritional value can be equal to th...

AI Technical Summary

Problems solved by technology

[0009] In view of the problem that soybean products are the main source of protein in the production raw materials of young ruminant milk substitutes, the combination of pea protein isolate and rice protein concentrate is used as a substitute; in view of the special requirements for rumen development of young ruminants, the content of dietary fiber in the feed is increased.
