Problems solved by technology

However, none of these anti-heat stress additives (things) can really be safe and efficient. For example, VC is easily oxidized and invalidated during the addition process, and it is difficult to estimate how much it can be used by the body in the end. Some anti-heat stress drugs Long-term use, it is difficult to avoid toxic side effects and drug residues

Abstract

The present invention provides one kind of heat stress resisting feed additive, which is mixture of mint oil coated in beta-cyclodextrin, tea polyphenol and dried old orange peel in the weight proportion among the mint oil, tea polyphenol and dried old orange peel of 1-4 to 4-8 to 100. The feed additive made with natural materials may be applied regularly safely. Adding the feed additive in 0.5-1.0 % into the mixed feed for pig and chicken can lower the rectal temperature of heat stress animal and lower the contents of serum creatine phosphokinase, serum cortisol and serum lactic dehydrogenase, so as to increase feed intake. The heat stress resisting feed additive can raise the productivity of animal and has high marketability.

Description

(1) Technical field [0001] The invention relates to an anti-heat stress feed additive for improving the production performance of livestock and poultry in a hot environment. (2) Background technology [0002] Heat stress refers to the sum of non-specific physiological responses made by the body in a high ambient temperature to any demands placed on the body by the thermal environment. Livestock and poultry under a heat stress environment not only have changes in their physiological functions and reduced feed intake, but also lead to changes in the distribution and efficiency of feed energy in the body, resulting in a decline in production performance. With the rapid development of intensive high-density breeding methods, breeding enterprises are increasingly demanding to alleviate the environmental pressure brought by the high temperature in summer on the breeding industry. [0003] Under general production conditions, it is unrealistic to control the ambient temperature of...
