Low-protein dietary premix and feed for growing pig

Abstract

A low-protein ration premix and feed for growing pigs, specifically, a low-protein ration premix for growing pigs, specifically, a lysine, methionine, threonine, tryptophan, valine Amino acid and other commercial amino acids are used in low-protein diet premixes for growing pigs, so as to adjust the amino acid balance in the crude protein diet and improve the utilization rate of the low-crude protein diet; on the premise of improving the growth performance of pigs In this way, the consumption of protein raw materials can be reduced by 2-4%, and the nitrogen discharge of animal husbandry can be reduced by 20-50%, so as to reduce the pollution of animal husbandry to the environment. A feed for growing pigs, referring to the latest nutritional standard model for growing pigs, and designing a low-protein ration based on the "ideal amino acid" model, so that the crude protein content of the full-price feed ration formulated can be reduced to 14.0-15.0%, combined with local The resource features a variety of growing pig feeds utilizing low protein ration premixes for growing pigs.

Description

technical field [0001] The invention relates to feed additives and feed, in particular to a low-protein diet premix and feed for growing pigs. Background technique [0002] The rapid development of my country's animal husbandry has provided the society with rich meat, eggs, milk and other protein foods, and people's living standards have been significantly improved. In 2011, my country's total pork production was 50.53 million tons, maintaining the world's largest pork production volume, and the per capita meat Possession has also exceeded the world average. [0003] The rapid development of the animal husbandry industry has caused serious pollution to the environment. According to estimates, each pig in the pig industry produces an average of 2.5 tons of feces and urine per year, and a pig farm with 10,000 heads discharges at least 30,000 tons of feces to the surrounding environment every year. It is 100-150 tons, and there are more than 200 feces odor components; secondly,...

Problems solved by technology

But only added lysine and methionine in this invention, did not add threonine, tryptophan, valine and other limiting amino acids in the growth process of pigs; The content of soybean meal is still as high as 21%, which cannot avoid the waste of crude protein in the diet, and has not exerted the maximum potential of "amino acid balance"
