Description

technical field [0001] The invention belongs to the field of feed additives, in particular to an additive for improving the anti-stress ability of laying hens. Background technique [0002] During the breeding process, laying hens will be subject to a lot of stress due to intensive feeding. There are many stress factors in the large-scale production of laying hens, which can be roughly divided into external factors and internal factors. Intrinsic factors are mostly seen in the breed factors of laying hens; there are many external common factors, such as laying eggs, feeding, temperature, density, humidity, light, ventilation, immunization, disinfection, harmful gases, dietary nutrient levels, water supply, and feed Sudden changes in methods etc. are stressors. Stress can lead to poor growth and development of laying hens, and poor eggshell quality during laying. [0003] In actual production, because the stress response is not intuitive in most cases, the breeder only foc...

[0005] The Chinese patent "A Chinese Herbal Medicine Additive for Laying Hens to Increase Yield and Anti-stress", its application number is: 201410741770.1, is just a simple addition of Chinese herbal medicine additives for anti-stress laying hens. It is not easy to control the impact, and it contains a variety of expensive medicinal materials, which increases the feeding cost, so it is not economical and applicable, and it is not conducive to popularization and use

[0006] The Chinese patent "A Formula Feed for Alleviating Heat Stress of Laying Hens", whose application number is 201310510559.4, discloses a feed for relieving heat stress of laying hens. The formula feed is used in a large amount and the cost is relatively high. In the case of stress, there is no strong pertinence, and the formula feed only plays a role in relieving heat stress
