Abstract

A low-protein premix adopting sanguinarine to replace tryptophan and applied to growing pigs comprises components in percentage by weight as follows: 8.45%-9.12% of L-lysine hydrochloride, 1.85%-2.76% of L-threonine hydrochloride, 1.74%-2.45% of DL-methionine, 10.25%-13.01% of dicalcium phosphate, 9.3%-10.85% of sodium chloride, 29.24%-31.57% of limestone powder, 2.84%-3.50% of a mineral premix, 2.37%-2.75% of choline chloride, 0.50%-0. 85% of a vitamin premix, 0.5%-1.10% of a mildew preventive, 0.36%-0.52% of an antioxidant, 0.2%-0.5% of a growth promoter, 0.15%-0.45% of wheat enzyme, 0.05%-0.15% of phytase, 0.25%-0.80% of a sanguinarine premix and the balance of a carrier. The invention further discloses formula feed containing the premix and applied to the growing pigs. According to the premix and the formula feed containing the premix and applied to the growing pigs, balance of amino acid in the formula feed containing the premix and applied to the growing pigs is realized, and the cost is low; the ingestion condition of the growing pigs is good; the sanguinarine further protects intestinal health of the growing pigs and promotes the development and perfection of digestive systems of the growing pigs, and the use amount of antibiotics in the low-protein formula feed is reduced.

Description

technical field [0001] The invention relates to a low-protein feed for growing pigs, in particular to a low-protein premix and compound feed for growing pigs in which sanguinarine replaces tryptophan. Background technique [0002] Soybean meal is a high-quality protein raw material for pig feed, but my country's soybean resources are insufficient, and more than 80% of soybeans have to rely on imports. Therefore, the problem of soybean meal resources has always been a major bottleneck restricting the development of feed enterprises. As a kind of plant protein, soybean meal contains a large difference in composition ratio of 20 kinds of amino acids from that of pork. Therefore, when using the index of amino acid content in compound feed to design feed formula, you can use "soybean meal + "Feed amino acid" instead of soybean meal can effectively provide certain amino acids required by pigs, reduce the proportion of soybean meal added in the formula, and reduce the crude protei...
