Abstract

The invention discloses a feed additive of promoting mammary gland development of replacement gilts and gestating sows through a nutritional means. The feed additive is composed of the following components according to the following proportions: 15-30% of cysteamine hydrochloride, 10-30% of vitamin E, 5-25% of daidzein, and the balance being glucose. The additive can modulate neuroendocrine system of the sows, increase intake for mammary gland nutrients of the sows, stimulate growth of mammary gland lobular acinus and mammary gland ducts, promote mammary gland development of the replacement gilts and gestating sows, and lay a good foundation for milk output of lactating sows.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for promoting mammary gland development of back-up and pregnant sows, and belongs to the field of sow nutrition. Background technique [0002] In pig production, the development of mammary glands in sows directly determines the quantity and quality of milk produced. Lactating sows provide high-quality and sufficient milk to ensure the nutritional supply of piglets, reduce the mortality rate of piglets after birth, increase the weaning weight of piglets, reduce the weaning stress of piglets, and enable piglets to grow rapidly in the later growth and finishing stages and give full play to their genetic potential , shorten the time to market and lay a good foundation. Since the nutritional status of animals is an important factor affecting the development of animal mammary glands, it is absolutely possible to promote the mammary gland development of gilts and pregnant sows through...
