Preparation method of middle and large pig low-protein concentrated forage for wheat based diets

Abstract

The invention which discloses a preparation method of a middle and large pig low-protein concentrated forage for wheat based diets belongs to the technical field of concentrated forages. The preparation method comprises the following steps: uniformly mixing100wt% of raw materials, and packaging the raw materials, wherein the raw materials comprise the following components, by weight, 40-60 parts of soybean meal, 7-10 parts of peanut meal, 4-6 parts of cotton meal, 4-6 parts of corn lees, 4-6 parts of corn protein flour, 3-4 parts of rice bran meal, 2-4 parts of soybean oil, 4-6 parts of stone flour, 2-3 parts of calcium hydrogen phosphate, 1-3 parts of salt, 1-2 parts of 65% lysine, 0.2-0.5 parts of 98.5% threonine, 0.3-0.5 parts of 10% tryptophan, 0.05-0.1 parts of a composite enzyme, 0.01-0.02 parts of phytase, 0.01-0.02 parts of choline chloride and 0.5-1 part of a premix. The preparation method has a beneficial effect that unfavorable factors can be fully eliminated and a corn based diet effect can be reached through the improvement of a production technology and the application of exogenous nutrients and forage additives, so the preparation method has great grain saving and environmental protection meanings.

Description

technical field [0001] The invention relates to a preparation method of a low-protein concentrated feed for large pigs in a wheat-type ration, and belongs to the technical field of concentrated feed. Background technique [0002] Animals' need for protein is essentially the need for amino acids. The design of low-protein diets is based on the digestible amino acid content of the ideal protein model, mainly by adding synthetic amino acids to maintain the balance of the main essential amino acids in the diet, so as to meet the amino acid needs of animals and meet the energy needs of animals at the same time. In recent years, animal nutrition studies at home and abroad have shown that the efficiency of animals using free amino acids is equal to the efficiency of using amino acids in protein. As long as the balance of amino acids is maintained, there is no biological limit to adding free amino acids to the diet. The preparation of low-protein diets is based on this, using synth...

Problems solved by technology

However, from a nutritional point of view, there are certain differences in energy raw materials between the two. In terms of pig nutrition, the traditional wheat-based feed has a higher feed-to-meat ratio than the corn-based feed, and wheat contains a high level of soluble arabinoxylan. And a small amount of soluble glucan, these polysaccharides can absorb 10 times their own water, form a high-viscosity solution in the small intestine, thereby forming over-wet feces, and prevent the absorption of nutrients, causing nutritional diarrhea; the starch structure of wheat is also related to Corn is different, its starch is small granular starch, the diameter is only 1 / 5 of corn, and 76% of wheat starch is amylopectin, which is difficult to digest; in addition, wheat contains higher crude fiber content
