A combination of multiple protein sources for young ruminant milk substitutes and its application

Abstract

The invention relates to a polyprotein source combination applicable to the milk replacer of young ruminants and application of the polyprotein source combination.The polyprotein source combination comprises soybean protein concentrate, rice protein powder and wheat protein powder or peanut protein concentrate.The invention further provides another polyprotein source combination which is formed by optional one of the soybean protein concentrate, the rice protein powder, the wheat protein powder and the peanut protein concentrate or combined by two of the soybean protein concentrate, the rice protein powder, the wheat protein powder and the peanut protein concentrate.Test results prove that when 70% of the milk protein in the milk replacer is replaced by the combination of the soybean protein concentrate, the rice protein powder and the wheat protein powder or the peanut protein concentrate, the combination of the soybean protein concentrate, the rice protein powder and the wheat protein powder or the combination of the soybean protein concentrate, the rice protein powder and the peanut protein concentrate can acquire good growth performance and high nutrition digestion rate, and the combination of the soybean protein concentrate, the rice protein powder, the wheat protein powder and the peanut protein concentrate is worse than the combination of the soybean protein concentrate, the rice protein powder and the wheat protein powder or the combination of the soybean protein concentrate, the rice protein powder and the peanut protein concentrate.

Description

technical field [0001] The invention relates to the field of feed for ruminants in animal husbandry, in particular to a calf and lamb milk substitute effectively combined with various plant proteins, which improves growth performance and health level and reduces breeding costs. Background technique [0002] In recent years, the use of milk substitutes for early weaning of young ruminants such as calves and lambs is an effective way for modern cattle and sheep breeding. Protein is one of the most important nutrients in milk substitutes, and its source and quality have become an important factor affecting feed quality and animal breeding costs. The protein raw materials commonly used in milk substitutes mainly include milk protein and non-dairy protein. Milk protein has the advantages of balanced amino acid composition, low level of anti-nutritional factors, and high digestibility. It is an excellent protein source in calf and lamb diets. However, milk protein resources in my ...

Problems solved by technology

[0010] But, inventor finds, because soybean protein has more comprehensive nutritional labeling and the antinutritional factor of lower content than other protein, if reduce the consumption of soybean protein in the ration and only adopt certain kind of vegetable protein to replace soybean protein, it is very easy There may be problems such as unbalanced nutrient composition in raw materials, anti-nutritional effects of anti-nutritional factors, and digestive tract discomfort in young ruminants
