Sow mixed feed improving reproductive performance of pregnant sows and preparation method of sow mixed feed

Abstract

The invention discloses a sow mixed feed improving the reproductive performance of pregnant sows and a preparation method of the sow mixed feed. The sow mixed feed comprises the following components in parts by weight: 55-60 parts of corn, 3-8 parts of barley, 12-17 parts of bran, 2-5 parts of fish meal, 4-8 parts of corn DDGS, 4-6 parts of bean pulp, 1-1.5 parts of calcium hydrophosphate, 0.5-1 part of limestone powder, 1-2 parts of bentonite, 0.2-0.5 part of lysine, 0.5-1 part of arginine, 0.1-0.3 part of methionine, 0.1-0.3 part of threonine, 0.1-0.3 part of choline chloride, 0.5-1 part of an aspartic acid, 0.05-0.1 part of an acidifier, 0.01-0.05 part of a microbial preparation, 0.3-0.5 part of salt, and 1-2 parts of a premixture. The sow mixed feed and the preparation method can balance the level of the amino acid in a sow, increase the amino acid and energy level, improve the immunity and the anti-stress ability of the sow, reduce the residue of toxins and harmful germs in a sow body, reduce the sow constipation, and further improve the reproductive performance of the sow.

Description

technical field [0001] The invention relates to a sow compound feed and a preparation method thereof, belonging to the technical field of compound feed, in particular to a sow compound feed for improving the reproductive performance of pregnant sows and a preparation method thereof. Background technique [0002] With the continuous increase of feeding costs, the reproductive performance of sows has been paid more and more attention by farmers. The reproductive performance of sows directly determines the economic benefits of pig farms, and the reproductive performance of foreign breeds raised in intensive pig farms Generally poor, coupled with insufficient management level and limited production conditions, there is a certain gap between our current production capacity and the world's advanced level. Sows have a large demand for various nutrients during pregnancy, and the lack of nutrition coupled with various stresses in the production management process seriously affects th...

However, there is currently no effective feed modification for this phenomenon

[0003] On the other hand, studies have shown that aspartic acid is the synthetic precursor of lysine, threonine, isoleucine, methionine and other amino acids and purine and pyrimidine bases in organisms, and participates in many metabolisms as an amino provider in organisms At the same time, aspartic acid is the main energy source of the intestinal mucosa of pigs, which can provide energy for many metabolic processes in the intestine; in addition, aspartic acid also has a certain immune effect, which can relieve intestinal inflammation caused by weaning stress in piglets injury, but has not been reported in sow compound feed
