Abstract

The invention discloses heat stress resisting premix for laying hen, which is prepared from the following components in parts by weight: 90-130 parts of glutamine, 5-10 parts of citric acid, 1-2 parts of fumaric acid, 2-3 parts of sodium acetate, 2-3 parts of sodium diacetate, 4-5 parts of sodium butyrate, 1-2 parts of phenylacetic acid, 0.1-0.15 part of zinc bacitracin, 6-8 parts of benzoic acid, 15-30 parts of selenium yeast, 2-4 parts of astaxanthin, 8-12 parts of gamma-aminobutyric acid, 100-150 parts of oligosaccharide and 650-800 parts of three-times solid fermentation black tea leaves. Compared with the prior art, the invention has the advantages that the heat stress resisting premix for laying hen and the preparation method of the heat stress resisting premix can effectively lower the pH of the digestive tract of the laying hen, inhibit the growth of harmful microbes, promote the breeding of beneficial microorganisms, optimize the intestinal tract fauna, improve the nutrient substance digestibility, enhance the heat stress resisting capacity of the laying hen, enhance the immunity and the disease resistance of the laying hen, and improve the laying rate.

Description

technical field [0001] The invention relates to a feed for laying hens, in particular to an anti-heat stress premix for laying hens and a preparation method thereof. Background technique [0002] Layer chickens are chickens used to lay eggs. Unlike broilers, laying hens focus on improving egg production and egg quality. With the rapid development of poultry breeding technology, large-scale breeding of laying hens has become very common. However, in the process of large-scale breeding, due to the high breeding density, it is difficult to dissipate heat in the chicken house, and the temperature in the chicken house is relatively high, especially at high temperature. In the summer when the temperature is too high, coupled with the rich feathers and vigorous metabolism of laying hens, the chicken itself does not have sweat glands to perspire and cool down. Instead, it increases the number of times of mouth breathing to expel moisture from the lungs and help dissipate heat. Exc...
