Low-protein balance amino acid piglet compound feed

Abstract

The invention relates to the technical field of special feed for young animals, in particular to low-protein balance amino acid piglet compound feed which comprises, by weight, 70-74 parts of corns, 16-18 parts of bean pulp, 4-5 parts of bran, 0.8-1.5 parts of fish meal, 1-3 parts of compound additives and 0.45-0.60 part of lysine. According to the feed, the usage amount of the bean pulp is less, feed cost is reduced, crude protein content is reduced by 2%, intestinal health of piglets can be facilitated, heat stress can be resisted under tropical conditions of Guangdong and the like, and nitrogen emission is decreased. Researches show that when dietary protein level is reduced by 1%, the nitrogen emission is reduced by 7%, various primary indicators such as metabolic energy and amino acid cannot be changed, production performance cannot be affected, and a metabolic energy system and various nutritive indexes are accurately adjusted, so that the compound feed is more accurate in nutrition.

Description

Technical field [0001] The invention relates to the technical field of special feed for young animals, and more specifically, to a low-protein balanced amino acid compound feed for piglets. Background technique [0002] As a young animal, piglets need to use some special feeds to meet the needs of healthy growth. During the growth of piglets, the content of crude protein in the diet can be appropriately reduced when the essential amino acids and nitrogen meet the needs, because the need for protein in pigs is actually the need for amino acids. In traditional corn-soybean meal-type diets, because corn contains less lysine, in order to meet the pig’s demand for lysine and other amino acids, the amount of soybean meal must be added, which makes the diet coarser. The protein content is higher. Diets with high protein content directly lead to the waste of essential amino acids and nitrogen through fecal and urine excretion, which also reduces the nitrogen utilization rate of amino a...

Problems solved by technology

However, the price of protein raw materials is high, and the cost of feed is high; high-protein diets have more nitrogen emissions, more water consumption, and more nitrogen is carried and discharged by urine, which pollutes the environment more and is not conducive to sustainable development; It is not conducive to intestinal health; high-protein diets are not conducive to resistance to heat stress in tropical climates such as Guangdong
