Piglet intestinal health regulation and control bioactive peptide fodder additive and application thereof

Abstract

The invention discloses piglet intestinal health regulation and control bioactive peptide fodder additive and application thereof. The active peptide fodder additive is prepared by the following steps: mixing vital gluten and silkworm chrysalis meal, adding water, and carrying out uniformly stirring; adding papain and trypsin, adjusting the pH value to 7.0 to 8.0, and carrying out enzymolysis at atemperature of 50 to 55 DEG C for 30 to 60 minutes to obtain an zymolyte; inoculating bacillus subtilis and saccharomyces cerevisiae into a solid-state fermentation culture medium prepared by the zymolyte, carrying out blending fermentation culturing for 30 to 45 hours at a temperature of 33 to 37 DEG C, and drying the fermentation mixture to obtain the bioactive peptide fodder additive. With theactive peptide, intestinal mucosa villi can be prevented from excessively shrinking and recessing deepening can be prevented 1-7 days after weaning of piglets and the intestinal mucosa villi height can be remarkably increased 8 to 14 days after weaning.

Description

[0001] (1) Technical field [0002] The invention relates to an active peptide feed additive for regulating intestinal health of piglets, a preparation method and application thereof. [0003] (2) Background technology [0004] Early weaning can improve the fertility of sows, increase the annual litter size of sows, reduce the transmission of diseases from mothers to piglets, and improve the production performance and carcass quality of growing pigs, and at the same time increase the utilization rate of equipment such as delivery rooms . However, an important problem brought about by early weaning is how to improve the growth performance of weaned piglets. After weaning, the nature of the diet of piglets has undergone major changes, and the digestive tract of piglets has not yet fully developed, the activity of digestive enzymes is insufficient, and the immune function has not yet matured. Moreover, weaning is not only related to physiological changes, but also changes in psyc...

Problems solved by technology

However, an important problem brought about by early weaning is how to improve the growth performance of weaned piglets. After weaning, the nature of the diet of piglets has undergone major changes, and the digestive tract of piglets has not yet fully developed, the activity of digestive enzymes is insufficient, and the immune function has not yet matured. Moreover, weaning is not only related to physiological changes, but also changes in psychology, environment and nutritional status, so it often manifests as poor appetite, digestive disorders, diarrhea, growth retardation, and low feed utilization. The so-called "piglet early weaning syndrome"
