Problems solved by technology

Dietary energy level and evaluation system have always been a hot spot in nutrition research, especially the application of net energy (NE) system in swine ration formulation has brought opportunities for the development of traditional nutrition theory, but the existing reports are very limited. Few systems have conducted further research on this system for low-protein diets

Abstract

The invention discloses low-protein daily ration for a growing pig under a net energy system and an application thereof, and belongs to the field of feed processing. The method comprises the steps of: taking the growing pig with the weight being 20-50kg as a research object, utilizing corn-bean pulp daily ration, reducing the protein content of the daily ration by 2% on the basis of the standard recommended by the National Research Council, simultaneously supplying lysine, methionine, threonine and tryptophan; adding mannan oligosaccharide, multivitamins, complex phosphoesterasum, probiotics and the like to form the low-protein daily ration for the growing pig under the net energy system; crushing, mixing, pelletizing then dosing, and packaging the pelletized feed and a probiotic component in a mixing manner to obtain the product disclosed by the invention. The animal feed utilization rate can be improved; the use quantity of antibiotic medicines in the feeding of animals is effectively reduced; the immunity of fed animals is improved; the security of animal meat products is improved; and the raise efficiency is also improved. The low-protein daily ration is scientific in process design, high in production efficiency, low in cost, and suitable for multi-variety and small-scale production.

Description

technical field [0001] The invention belongs to the field of feed processing, and in particular relates to the formulation design and preparation method of low-protein rations for growing pigs under the net energy system. Background technique [0002] In the theory of protein nutrition, the animal's demand for protein is essentially the utilization of amino acids (AA), as long as the diet provides a reasonable amount of amino acids, the animal's protein needs can be met (Li Defa, 2003). However, due to the influence of industrial production, the traditional ration formulation can only guarantee the amino acid demand through the protein level, which leads to the limitation of the rational use of feed resources. The excretion of pollutants such as nitrogen and phosphorus increased, which brought huge pressure to the breeding environment. The application of synthetic amino acids makes the nutrient supply more balanced, helps to improve the utilization rate of protein, and brin...
