Fermented selenium-rich vegetable feed additive

Abstract

The invention discloses a fermented selenium-rich vegetable feed additive. A preparation method of the fermented selenium-rich vegetable feed additive comprises the following three steps: (1) preparation of a selenium-rich yeast culture solution, (2) preparation of a traditional Chinese medicine fermentation culture medium and (3) traditional Chinese medicine fermentation. The preparation method is characterized in that the step (2) comprises the following steps: (2.1) preparation of a Chinese herbal medicine probiotics culture medium and (2.2) inoculation. The fermented selenium-rich vegetable feed additive designed by the invention is a novel environmentally-friendly safe feed additive which contains fermented traditional Chinese medicines and organic selenium and is capable of resisting heat stress of pigs. By adequately combining with physiological characteristics of heat stress pigs and taking oxidative stress resistance as the main characteristic, after pigs are fed with the additive, the weight increment and feed to gain ratio of the pigs in a high-temperature environment can be remarkably improved, the oxidation resistance and immunologic functions of the pigs can be enhanced, and the stress resistance of the pigs is effectively exerted; and after the additive is used for a long time, no toxic and side effects are generated, and no harmful substance is remained.

Description

technical field [0001] The invention relates to a feed additive, in particular to a fermented selenium-enriched vegetable feed additive. Background technique [0002] In most parts of southern my country, the temperature and humidity are high in summer and early autumn. In recent years, the temperature in the central and northern parts of the country has also been very high. In addition, there is no temperature-controlled and humidity-controlled pig house like developed countries. Therefore, the heat stress problem of pigs It is becoming more and more serious, especially for pigs under intensive high-density rearing, which has a great impact. Heat stress not only affects the behavior and production performance of pigs, but also has a great impact on the immune function, reproductive performance and pork quality of pigs. Therefore, how to alleviate the harm of heat stress to pig production and improve its production performance under high temperature conditions has become an ...

Problems solved by technology

In terms of the development of anti-heat stress agents, some existing anti-heat stress drugs are used for a long time, it is difficult to avoid toxic side effects and drug residues, and the dosage is also difficult to control, and some commonly used anti-heat stress additives (such as VC ), it is easy to be oxidized and invalidated during the addition process, and it is difficult to estimate how much can be absorbed and utilized by the body in the end, and the final effect is not ideal. There are also some anti-heat stress drugs. , does not meet modern food safety requirements
