Problems solved by technology

One week before broiler slaughter (5-6 weeks old), heat stress causes physiological dysfunction and growth retardation, which leads to a series of physiological and organ function declines, especially reduces meat quality, resulting in PSE (pale , gray, juicy) meat, causing greater economic losses

Abstract

The invention discloses a heat stress preventing premix compound for big broiler chickens of 5-6 weeks age. The premix compound is composed of the following components in parts by weight: 100-150 parts of glutamine, 10-20 parts of selenium yeast, 1-2 parts of sodium diacetate, 1-2 parts of sodium acetate, 2-3 parts of sodium butyrate, 0.5-1 part of phenylacetic acid, 3-5 parts of benzoic acid, 2-3 parts of astaxanthin, 5-10 parts of gamma-aminobutyric acid, 100-150 parts of oligosaccharide and 650-800 parts of twice-solid-fermentation tea leaves. The invention also discloses a fodder for big broiler chickens of 5-6 weeks age. Compared with the prior art, the premix and fodder disclosed by the invention have the following advantages of improving the broiler chicken heat-stress resistance, resolving the stress damage, improving the growth performance of the broiler chickens in high temperature environment, prompting the growth of the big broiler chickens, improving the intestinal mucosal function of the big broiler chickens, reducing the morbidity of the broiler chicken and improving the chicken meat quality.

Description

technical field [0001] The invention relates to a feed for broiler chickens, in particular to an anti-heat stress premix and feed for broiler chickens aged 5-6 weeks. Background technique [0002] With the rapid development of animal genetic breeding technology, the growth rate and muscle yield of modern meat poultry have been significantly improved, but the over-breeding of growth rate and muscle yield has enhanced the body's sensitivity to high temperature. Due to the greenhouse effect, the earth's climate continues to warm, and the range of high temperature in summer is gradually expanding. The impact of high temperature environment on the poultry industry will become more and more serious. In recent years, the domestic broiler chicken industry has developed rapidly and achieved remarkable results. However, broiler chickens are "resistant to cold and heat", especially in the later stages of growth. The metabolic intensity is high, the heat production is high, and the high...
