Nutrition feed capable of promoting mammogenesis of sow

Abstract

The invention relates to a nutrition feed capable of promoting mammogenesis of sow. The feed comprises a backup material eaten by the sow in a backup period, a pregnancy material eaten in a pregnancy period and a lactation material eaten in a lactation period, wherein the backup material is prepared from the following components in parts by weight: 60-65 parts of corns, 19-23 parts of bean pulp, 8-10 parts of wheat bran, 1-2.5 parts of fish meal, 1.5-3 parts of soybean oil, 0.15-0.2 part of lysine, 0.08-0.15 part of methionine, 0.0008-0.001 part of vitamin A, 0.02-0.03 part of vitamin E, 0.01-0.03 part of organic selenium and 3-5 parts of premix. Compared with the prior art, the nutrition feed has the advantages that the feeds which accord with the characteristics of corresponding physiological stages are prepared according to the differences of physical conditions and the nutrient requirements of the sow in the backup period, the pregnancy period and the lactation period respectively; the components are reasonable and nutritionally complementary; continuous promotion of mammogenesis of the sow is achieved by feeding different feeds at different stages; and the normal physiological activities of the sow are ensured.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and relates to a nutritional feed for promoting mammary gland development of sows. Background technique [0002] Piglets generally have the highest mortality rate within 0-7 days after birth. Since piglets have not been weaned during this period, they mainly obtain nutrients from the milk of sows. Therefore, one of the main causes of piglet death comes from sows, such as sows Decreased milk production or changes in milk composition may cause newborn piglets to only obtain part of the nutrients, reducing the survival rate of piglets. Since milk is the most important source of nutrition for lactating piglets, and the mammary gland is the only tissue that produces milk, in order to improve milk production and the survival rate of piglets before weaning, the development of mammary glands in sows has gradually attracted more and more attention. [0003] Studies have shown that mammary gland developm...

AI Technical Summary

Problems solved by technology

However, this technical solution does not take into account the differences in the nutrients required by sows at different stages and their relative content. Only a single formula feed additive is used to promote the mammary gland development of sows in the back-up period and early pregnancy, and the promotion effect is very limited.
