Abstract

The present invention discloses a fermented selenium-rich plant feed additive resistant to pig heat stress and a preparation method of the feed additive comprises the following three steps: (1) preparation of selenium-rich yeast culture medium; (2) preparation of traditional Chinese medicine fermentation culture medium; and (3) traditional Chinese medicine fermentation. The plant feed additive is characterized in that: the traditional Chinese medicine fermentation culture medium obtained in the step 2 includes (2.1) preparation of Chinese herbal medicine probiotics and (2.2) inoculation steps. The designed fermented selenium-rich plant feed additive is a pig heat stress resistant novel feed additive which is green and safe, contains traditional Chinese medicines, and combines organic selenium. The feed additive fully integrates the physiological characteristics of heat-stressed pigs, uses anti-oxidative stress as main features, can significantly improve the pig weight gain and feed-weight ratio in a high-temperature environment, and enhance pig anti-oxidation resistance and immune function after being fed, effectively plays the roles of pig stress resistance, and has non-toxic or side effects and no harmful substance residues after a long-term use.

Description

technical field [0001] The invention relates to a feed additive, in particular to a fermented selenium-enriched vegetable feed additive capable of resisting pig heat stress. Background technique [0002] In most parts of southern my country, the temperature is high in summer and early autumn, and the humidity is high. In recent years, the temperature in summer in the central and northern parts has also been very high. In addition, there is no fully enclosed pig house with temperature control and humidity control like developed countries, so the problem of heat stress in pigs It is getting more and more serious, and it has had a great impact on pigs under intensive high-density feeding. Heat stress not only affects the behavior and production performance of pigs, but also has a great impact on the immune function, reproductive ability and pork quality of pigs. Therefore, how to alleviate the harm of heat stress to pig production and improve its production performance under hi...
