Abstract
The invention discloses a low-protein daily ration of a three-way cross growing pig and belongs to the technical field of a pig industry of animal husbandry. The formula of the daily ration comprises 66-68 parts of corns, 4-4..6 parts of wheat bran, 15.4-24 parts of soybean meal, 0.88-0.92 part of stone powder, 0.89-1.07 parts of calcium hydrophosphate, 0.4 part of edible salt, 0.168-0.44 part of L-lysine hydrochloride. 0.040-0.081 part of DL-methionine, 0-0.12 part of L-threonine, 0-0.03 part of L-tryptophan, 0.208-0.582 part of zeolite powder and 1.00 part of premixed powder. According to the technology disclosed by the invention, according to an ideal protein amino acid model of the three-way cross growing pig, the rough protein level of the daily ration of the three-way cross growing pig are reduced by three percent, so that the aims of keeping the growing performance, reducing the cost of a feed formula and reducing nitrogen content in excrements are achieved.
Description
Technical field
The invention belongs to pig industry field in the animal husbandry, relate to the animal nutrition field, be specifically related to a kind of three way cross growing swine low-protein daily ration.
Background technology
At present, the pig industry development is the important component part of China's animal husbandry rapidly.The problem of environmental pollution that pig industry causes is serious day by day.The pig feed of energy-saving and emission-reduction, the low elimination of nitrogen of exploitation is the important measures that realize the pig industry sustainable development.Pig is discharged the nitrogen nutrient of not digesting and assimilating in a large number through fecaluria every day, and average every growing and fattening pigs produce 4.55 kilograms excrement every day, this means the annual average 9.5 kilograms of nitrogen of discharging of every fattening pig.Therefore, come balanced nutrients to need, improve efficiency of feed utilization, reduce the nutrient discharge rate,, reduce environmental pollution and have great importance for the economic benefit that improves whole Swine Production from the nutrition approach.
Protein is one of essential nutrient of pig; The nutrition of protein comes down to the nutrition of essential amino acid and nonessential amino acid, and ideal protein is meant that the amino acid composition of protein in the feed is formed with the amino acid of animal desired protein with ratio and ratio is consistent.The different growth phases of animal only are the difference on the absolute magnitude for amino acid whose requirement, and the ratio of each amino acid requirement is constant relatively.This is the theoretical foundation of ideal protein, and the key technology of ideal protein is the balance between amino acid.Use ideal protein pattern configurations daily ration, not only can suitably reduce the crude protein content of daily ration, and can reduce the discharge rate of nitrogen effectively.
Low-protein diet has carried out many researchs at home and abroad, and the result shows, reduces the daily ration gross protein value, and the synthesizing amino acid of corresponding additional shortage does not have influence to the growth performance of pig, but different results is appearred in dietary protein level reduction amplitude.This Project Study growing swine daily ration crude protein content is reduced the 1-4 percentage point of influence to crude protein content in pig growth performance, the ight soil respectively.Discovery reduces 1-3 percentage point with crude protein content, to the not influence of growth performance of pig, but the daily ration crude protein is reduced by 4 percentage points, has significantly reduced the growth performance of pig.This provides an enlightenment for the operating position of further studying low-protein diet, i.e. the crude protein content of low-protein diet preparation lower limit is to reduce by 3 percentage points or 4 percentage points.
Summary of the invention
The object of the present invention is to provide a kind of three way cross growing swine low-protein daily ration; Be a kind of according to three way cross growing swine ideal protein amino acid pattern; Through reducing by 3 percentage points of three way cross growing swine daily ration thick protein levels, reach the technology that keeps growth performance, reduces nitrogen content purpose in feed formula cost and the excreta.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:

Described daily ration is a 30-60kg three way cross growing swine low-protein daily ration.
Beneficial effect of the present invention: according to three way cross growing swine ideal protein amino acid pattern; Through reducing by 3 percentage points of three way cross growing swine daily ration thick protein levels, reach the purpose that keeps growth performance, reduces nitrogen content in feed formula cost and the excreta.
The specific embodiment
With " DLY " three way cross growing swine (30-60kg) is subjects; With reference to NRC (1998) growing swine nutritional need standard and ideal protein amino acid balance pattern; Keeping under the constant situation of daily ration total amino acid content and other trophic level; Reduce 1-4 percentage point of daily ration thick protein, promptly daily ration thick protein drops to 16.50% (test group 1), 15.50% (test group 2), 14.50% (test group 3), 13.50% (test group 4) respectively from 17.50% (control group).Control group, test group 1, test group 2,3 groups of tests, test are respectively established 3 repeating groups for 4 groups, and 6 pigs of each repeating groups carry out 40 days raising, and daily ration amino acid balance pattern and thick protein and amino acid levels are seen table 1, and daily ration is formed and trophic level is seen table 2.
When off-test, measure the individual body weight on an empty stomach of each repeating groups pig, the feed consumption of each repeating groups of system note, the growth performance of calculating pig (average daily ingestion amount, average daily gain, material anharmonic ratio).Respectively at 31d, 32d, 33d fix a point every day, regularly (7:00～16:00) collects the bright excrement appearance 300g of each repeating groups; Excrement appearance mixing with collection in three days; Excrement appearance is measured nitrogen element content in each repeating groups excrement appearance through 65 ℃ of oven dry 24h, pulverizing by GB/T 6432-1994 " crude protein assay method in the feed ".All test datas adopt the SPSS13.0 statistical software to carry out statistical analysis.
