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

Embodiment 1

[0050] Embodiment 1 low-protein diet growth performance test

[0051] 1. Diet and daily management

[0052] The rations of the experimental group were prepared in the ideal amino acid mode, and the protein levels were: 14.5% for growing pigs and 12.5% ​​for finishing pigs. : 16.4% for growing pigs, 14.5% for finishing pigs, and other nutritional indicators are not lower than those of the experimental group. The experimental pigs were fed in groups, with free access to food and water, and were fed once a day at 08:00 and 16:00.

[0053] 2. Experimental design

[0054] Select 160 large white barrows of about 40 kg, 80 in the test group and 80 in the control group, 4 replicates (pens) in each group, and 10 pigs in each replicate. In the feeding stage, the feeding stage of growing and finishing pigs is 35-60kg, and 60kg-marketing. The pre-test or refeeding period of the test is 3-5 days, and the pigs' weight reaches about 100kg. The growth performance of the pigs at each stage...

Embodiment 2

[0059] Example 2 Detection of ammonia and hydrogen sulfide in low-protein diet livestock house

[0060] 1. Experimental plan

[0061] Except that the experimental group and the control group were raised in separate livestock houses, other experimental schemes were the same as in Example 1.

[0062] 2. Index determination

[0063] Pig house ammonia (NH 3 ), hydrogen sulfide (H 2 S). After the full-term test, use the GS-3 atmospheric sampler to collect NH 3 and H 2 S gas sample, respectively adopt volumetric analysis method, iodine titration method to measure NH 3 mass concentration and H 2 S mass concentration.

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...
