Problems solved by technology

[0005] The current method of preventing and treating heat stress in chickens is mainly to control the temperature of the living environment and add drugs to the feed. Controlling the temperature of the living environment will increase the cost of breeding. Adding drugs to the feed is more common, such as the Chinese invention patent publication with the publication number "CN101081058B "An Anti-Heat Stress Feed Additive and Its Application", which has proved that tea polyphenols, peppermint and tangerine peel cooperate with each other to resist heat stress. However, heat stress causes more complex physiological changes in animals, and these The type of substance is relatively single, the function is limited, and the effect produced is not significant enough. It is necessary to add some enhancers to enhance the anti-stress effect
In addition, there are fewer types of feeds for laying hens to resist heat stress and increase egg production

Abstract

The invention discloses a feed for relieving heat stress of laying hens, and relates to the field of feed processing. The feed comprises the following raw materials: a corn powder, rice bran, soybean meal, peanut cakes, fish meal, bone meal, table salt, vitamins, a mint extract, a dried tangerine or orange peel extract, a rhizoma coptidis extract, tea polyphenols, citric acid, beta-carotene, organic selenium, zinc gluconate, copper sulfate, daidzein and astragalus polysaccharide. The feed is rationally prepared according to physiological change characteristics of the heat stress of the laying hens, can enhance the ability of the laying hens to resist the heat stress, and has obvious effect, so that the egg yield of the laying hens under a high temperature condition is not affected.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of feed processing, in particular to a feed for alleviating heat stress of laying hens. [0003] 【Background technique】 [0004] The optimum survival temperature for chickens is 21-26°C. At 26-32°C, chickens are not comfortable but can maintain normal physiological functions. If the temperature is higher than this range, the physiological functions of chickens will be disturbed, which is manifested in the body temperature of chickens. Increased, the body produces and accumulates a large number of free radicals, which cause oxidative damage to proteins and lipids in the body. At the same time, the activity of superoxide dismutase, which can inhibit and scavenge free radicals, decreases, causing chicken growth stagnation or production Decreased performance, reduced feed conversion rate, reduced immunity, and even death in severe cases, we call it heat stress. It is very common for chickens to drop or die every ...
