Abstract

The invention provides an application of creatine pyruvate as a feed additive for promoting rumen fermentation of heat stress beef cattle, and belongs to the field of feed additives. The proper use amount of creatine pyruvate used as a feed additive for promoting rumen fermentation of heat stress beef cattle is 20-60g / d.head, resource waste is caused by the too high addition amount, and the effectcannot be achieved due to the too low addition amount. As a feed additive for promoting rumen fermentation of heat stress beef cattle, creatine pyruvate can provide energy and a nitrogen source for rumen microbial fermentation at the same time, can effectively adjust the stress hormone level of the heat stress beef cattle, and can improve the oxidation resistance and rumen fermentation traits ofthe beef cattle to relieve the heat stress of the beef cattle.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to the application of creatine pyruvate as a heat-stress-promoting rumen fermentation feed additive for beef cattle. Background technique [0002] With the increasing intensity of beef cattle breeding and the increasing severity of the greenhouse effect, heat stress has become one of the important factors that endanger the performance of beef cattle. Especially in the southern provinces of my country, the summer is long, and the climate is hot, humid and rainy. High-temperature and high-humidity environment can easily induce the heat stress reaction of beef cattle, accompanied by oxidative stress in the body, manifested as decreased feed intake, slow growth, rumen function damage, digestive system disorder, and decreased nutrient utilization rate, etc., seriously affecting the production performance of beef cattle , causing huge losses in production. The rumen is the main...
