Low protein ration premix compound for growing pigs and using method thereof

Abstract

The invention provides a low protein ration premix compound for growing pigs and a using method thereof. The low protein ration premix compound consists of mountain flour, calcium hydrophosphate, salt, sodium bicarbonate, L-lysine hydrochloride, DL-methionine, L-threonine hydrochloride, L-tryptophan hydrochloride, an antioxidant and the like. The crude protein content of the prepared growing and fattening pig ration is respectively reduced from 16.4 percent to 14.5 percent and from 15.4 percent to 12.5 percent. The invention aims to add commodity amino acid to produce the low protein ration premix compound to enlarge the applicability of the low protein ration technology and improves the conversion efficiency of the ration, reduces the use of the protein raw materials, reduces the feeding cost and reduces discharge by reducing the concentration of the crude protein of the prepared ration.

Description

technical field [0001] The invention relates to a low-protein ration premix for growing pigs and a use method thereof, in particular to a growing pig premix which reduces the concentration of dietary protein and supplements commercial amino acids. technical background [0002] my country is a big pig breeding and consumption country. In 2007, there were 440 million pigs on hand, 565 million pigs were slaughtered, and 42.878 million tons of pork were produced. In the same year, 24.1 million tons of pig feed were produced. The rapid development of animal husbandry has provided human beings with rich protein food, which has significantly improved people's living standards. However, the development of the pig industry has also brought many problems to people. First, it causes environmental pollution. According to estimates, one pig produces an average of 2.5 tons of feces and urine per year, and a farm of 10,000 pigs discharges feces to the surrounding environment at least every...

Problems solved by technology

[0004] However, the current low-protein diet formulation technology based on the "ideal protein" model is still in the research stage (Liang Fuguang et al., 2005; Wu Shusong, 2009), and the reported low-protein diets that are actually used for commercialization are still few. Lu Mingbin (2007) invented "a preparation technology of a low-protein diet for fattening pigs", Chen Gang (2007) proposed "a low-protein diet for suckling pigs and its application method", and Li Qundao (2007) reported "a kind of low-protein diet for pregnant mothers". However, in terms of feed types, the above three inventions are all full-price feed products, which inevitably causes limitations in their use

First of all, the ratio of raw materials used is single, which is not conducive to the utilization of my country's extensive feed raw material resources; secondly, it is not suitable for self-batching methods, which is not conducive to technology promotion
