Low-protein amino acid balance daily ration, preparation method and application thereof

Abstract

The invention discloses a low-protein amino acid balance daily ration, a preparation method and the application thereof. The daily ration comprises the components based on parts by weight: 68-80 partsof corn, 3-20 parts of bean pulp, 6-20 parts of wheat bran and 4-5 parts of pre-mixed material, wherein the pre-mixed material comprises the following components: pig multi-vitamin, pig compound trace element, lysine, methionine, threonine, tryptophan, choline chloride, calcium carbonate, calcium hydrogen phosphate, phytase, common salt, ethoxy quinoline, trimethylamine B lactone, sodium glutamate and zeolite powder. Based on summary of the existing experimental data, the low-protein daily ration combines the actual conditions of China, utilizes the latest data information of raw materials made in China, fully takes the organic combination of the pre-mixed material and the main raw materials into account, and adopts a net energy system structure and a new nutrition model, thus developingthe utilization rate of feed to the utmost extent on the premise of ensuring the quality of animal products.

Description

technical field [0001] The invention relates to a low-protein amino acid balanced ration and its preparation method and application. Background technique [0002] Low-protein diet refers to a diet that reduces the protein level in the diet by 2% to 4%, and at the same time meets the needs of the type, proportion and quantity of amino acids in the diet of livestock and poultry, but the production performance of livestock and poultry remains unchanged. Since the essence of animal protein nutrition is amino acid nutrition, and more importantly, essential amino acids, so while reducing the crude protein content of the diet, supplementing essential amino acids can solve the problem of lack of some essential amino acids caused by low crude protein content. . As more and more industrial amino acids (L-lysine, L-threonine, L-methionine and L-tryptophan) come on the market and gradually decrease in price, the use of low-protein diets in production has become a A real possibility. ...

AI Technical Summary

Problems solved by technology

[0005] However, the existing low-protein diets still have shortcomings such as the lack of organic combination between the premix and the main raw materials and the unreasonable energy system and nutritional model used in the diet. The meat quality of the rear animal, such as the reduction of carcass quality such as lean meat percentage, backfat thickness, eye muscle area, etc.
