Abstract

The invention belongs to the technical field of sow breeding, and particularly relates to a composite additive bag for promoting mammary gland development of replacement gilts and application of the composite additive bag. The composite additive bag is prepared from an additive and a carrier; the additive is composed of cellulose, inulin, silymarin, baicalin and nicotinic acid; and the carrier iscomposed of zeolite powder and defatted rice bran. The composite additive bag for promoting the mammary gland development of the replacement gilts is researched and prepared according to an apoptosismechanism of mammary gland cells of the replacement gilts, physiological characteristics and reproductive physiological characteristics of mammary gland development of the replacement gilts and physicochemical characteristics of nutrient substances eaten by the replacement gilts. It is found that the weight of mammary glands of the replacement gilts in a third estrus period can be increased, apoptosis of the mammary gland cells in puberty is inhibited, development of mammary gland parenchyma is promoted, then lactation capacity of the gilts in a lactation stage is improved, and productivity and economic benefits of a farm are improved.

Description

technical field [0001] The invention belongs to the technical field of sow breeding, and in particular relates to an additive compound package for promoting mammary gland development of gilts and an application thereof. Background technique [0002] Pig milk provides the only source of nutrition and immunity barrier for newborn piglets. The lactation ability of a sow is an important indicator of the fecundity of a sow, and the development of mammary glands is directly related to the lactation ability of a sow. Mammary gland development can be divided into three stages, puberty, pregnancy and lactation. Studies have shown that gestation is the most vigorous period of mammary gland development in animals, but there are few studies on mammary gland development in puberty. The mammary gland is a complex secretory organ composed of many different cell types: epithelial cells grow from the nipple into fat pads, formed by adipocytes, and infiltrated by vascular endothelial cells,...
