Composite additive for improving colostrum quality and lactation yield of sows, and application thereof

Abstract

The invention relates to the technical field of feed additives, and especially relates to a composite additive for improving the colostrum quality and the lactation yield of sows, and an application thereof. Beta-hydroxy-beta-methylbutanoic acid is added to increase the fat content of colostrum, improve the energy and reduce the mortality of newborn piglets in 1-3 days; valine is combined as a branched chain amino acid to promote the synthesis of glutamine in the mammary gland; and the addition of carnitine, potassium butyrate, soy isoflavones, Vaccaria segetalis and glutamine improves the energy utilization rate of sow bodies, improves the energy utilization rate of piglets, promotes the feed intake of the sows, increases the fat content of colostrum and milk, promotes the development of the mammary gland, increases the lactation yield of the sows during lactation, ensures that the newborn piglets can absorb nutrients for improving the performances of the intestinal tract, and improves the growth performance of the piglets.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a compound additive for improving sow colostrum quality and lactation volume and its application. Background technique [0002] The level of sow lactation has become an important factor affecting the production efficiency of pig farms. In actual production, the colostrum quality and lactation volume of sows are very low, resulting in high mortality of piglets during lactation, and seriously affecting the growth performance of suckling piglets, affecting the development of piglets, resulting in poor overall growth performance of piglets; and, Increased sow body loss affects the sow's performance in the next reproductive cycle. For the nutritional adjustment of sows during the peripartum and lactation period, it will improve the quality of colostrum and lactation of sows. At this stage, supplements such as short-chain fatty acids, polyunsaturated fatty acids, functional ami...

Problems solved by technology

[0003] The improvement and increase of sow colostrum quality and lactation has always been the focus of sows in pig farms. However, in the prior art, the improvement measures adopted are still not ideal, and Wangbuliu has not been adopted. Combining traditional Chinese medicine ingredients such as Xingxing and β-hydroxy-β-methylbutyric acid to improve the quality of colostrum and lactation of sows has been published, and β-hydroxy-β-methylbutyric acid is used as an additive in pig feed Components, which are mainly to achieve the proliferation of sow embryonic muscle cells, and to improve the initial weight and survival rate of newborn piglets, such as the compound additive and application for promoting the proliferation and differentiation of sow embryonic muscle cells with patent application number 201510623803.7
