Problems solved by technology

It was found that reducing crude protein content by 1-3 percentage points had no effect on pig growth performance, but reducing dietary crude protein by 4 percentage points significantly reduced pig growth performance

Embodiment Construction

[0011] Taking "Du Changda" three-component hybrid growing pig (30-60kg) as the test object, referring to the NRC (1998) nutritional requirement standard for growing pigs and the ideal protein and amino acid balance model, while keeping the total amount of dietary amino acids and other nutritional levels unchanged In the case of 1-4 percentage points, the dietary crude protein was reduced from 17.50% (control group) to 16.50% (test group 1), 15.50% (test group 2), 14.50% (test group 3), 13.50% (test group 4). The control group, test group 1, test group 2, test group 3, and test 4 groups each set up 3 repetition groups, and each repetition group had 6 pigs, which were fed for 40 days, the dietary amino acid balance mode and the crude protein and amino acid levels See Table 1, and see Table 2 for dietary composition and nutrient levels.

[0012] At the end of the experiment, the individual fasting body weight of pigs in each repetition group was measured, the feed consumption of...

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 [0001] The invention belongs to the field of pig raising in animal husbandry, relates to the field of animal nutrition, and in particular to a low-protein ration for three-way hybrid growing pigs. Background technique [0002] At present, the pig industry is developing rapidly and is an important part of my country's animal husbandry. The problem of environmental pollution caused by pig farming is becoming more and more serious. Energy saving and emission reduction, and the development of pig feed with low nitrogen excretion are important measures to realize the sustainable development of pig industry. Pigs excrete a large amount of undigested and absorbed nitrogen nutrients through feces and urine every day. On average, each fattening pig produces 4.55 kg of manure per day, which means that each fattening pig excretes an average of 9.5 kg of nitrogen per year. Therefore, it is of great significance to improve the economic benefits of the entire pig product...
