Problems solved by technology

[0002] The growth and development of piglets is a key link related to pig production. Due to the unique digestive physiological structure of piglets, their digestive organs are not perfect, the physiological functions of digestive glands are not perfect, they lack congenital immunity, and their body temperature regulation function is not perfect. Stress resistance is poor, and piglets have a high incidence of various diseases and low survival rates under normal feeding conditions

Abstract

The invention provides a bioactive peptide for promoting the growth of piglets. The bioactive peptide contains the amino acid sequence shown in SEQ ID No. 1. The bioactive peptide can significantly improve the absorption and utilization rate of nutrients in feed by piglets, and promote the growth of piglets. Growth and development, reduce morbidity and improve piglet survival rate. Further, a preparation method of a bioactive peptide that promotes piglet growth and its application in promoting piglet growth and reducing piglet mortality is provided, and the bioactive peptide that promotes piglet growth and development is produced through the synergistic action of various enzyme-producing probiotics , used in piglets to promote the body's anabolism and fat decomposition, promote protein synthesis, achieve the purpose of promoting the growth of piglets and increase their growth speed, by regulating the hormone level of the endocrine system, play a role in promoting the growth and development of piglets, and overcome the hormone residues problems, to achieve the purpose of healthy and green farming.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a biologically active peptide that can effectively promote the growth and development of piglets, increase their growth speed and promote the growth of piglets, and its preparation method and application. Background technique [0002] The growth and development of piglets is a key link related to pig production. Due to the unique digestive physiological structure of piglets, their digestive organs are not perfect, the physiological functions of digestive glands are not perfect, they lack congenital immunity, and their body temperature regulation function is not perfect. Stress resistance is poor, and piglets have a high incidence of various diseases and a low survival rate under normal feeding conditions. Improving the absorption and utilization rate of nutrients in the feed by piglets, promoting the growth and development of piglets, reducing the inci...
