Mixed feed for increasing sow milk yield and preparation method thereof

Abstract

The invention provides a mixed feed for increasing sow milk yield. The mixed feed contains vitamins, organic trace elements and a carrier, and also contains the following components by weight percent: 30-40% of arginine and 25-35% of valine. The mixed feed is used from the sow gestation period of 80 days to the sow weaning period. The premix mainly contains the following components: the vitamins, the organic trace elements and the carrier, and especially contains arginine and valine. Compared with the conventional premix, the product provided by the invention contains arginine and valine, and the piglet birth weight and the sow milk yield can be effectively increased after the product is combined with a large amount of raw materials-maize, bean pulp, fish meal and expanded soybean.

Description

Technical field [0001] The present invention involves a feed, mainly for the mammal, trace elements, and amino acid mixed feed in the mammalie. Background technique [0002] During the lactation phase, vitamins are essential nutrients for sows. Reasonable vitamin levels are very important for high -yield sows.Because people do not know enough about the function of fat -soluble vitamins, the number of sows and the amount of lactation of sows have always been a problem that plagues pig producers. Among them, vitamin A plays an important role in reproductive function. Vitamin E maintains cell membrane in the sow breasts.Permeability plays an important anti -oxidant function; and corn -soybean meal -type lactating breasts diet usually lacks pyrine and needs additional supplements.In the late pregnancy, due to insufficient arginine, the birth weight of piglets was reduced. Therefore, to increase the weight of piglets and sows, sow secretion of lactation need to supplement sircinine an...

AI Technical Summary

Problems solved by technology

Due to the lack of clear understanding of the functions of fat-soluble vitamins, the number of sows and milk production has always been a difficult problem for pig producers. Among them, vitamin A plays an important role in reproductive function, and vitamin E maintains cell membranes in the mammary glands of sows. Permeability plays an important antioxidant function; and corn-soymeal-based lactating sow diets are often valine-deficient and require additional supplementation
