Biological feed additive capable of raising lean meat frequency of animals, its preparation method and application

Abstract

The invention discloses a biological feed additive capable of raising lean meat frequency of animals, comprising the following ingredients: 8-12wt% of beta-mannanase, 1.5-2.0wt% of soya bean oil, 1.8-2.5wt% of lysine, 0.04-0.07wt% of anti-oxidant, and the balance of corn protein powder. The biological feed additive capable of raising lean meat frequency of animals is prepared by firstly preparing beta-mannanase, and then mixing beta-mannanase with soya bean oil, lysine, anti-oxidant and corn protein powder in proportion. The biological feed additive can be used as an additive of a corn soybean meal daily ration with the additional amount of 1-3%. The additive disclosed herein is a pure biological product with safety and no toxicity, can raise the absorption and conversion rate of feed, significantly improve the body shape of pigs, effectively raise the lean meat frequency of animals, and reduce body fat contents.

Description

technical field [0001] The invention relates to a biological feed additive, in particular to a biological feed additive capable of increasing animal lean meat percentage, its preparation method and application. Background technique [0002] Since the reform and opening up, my country's national economy has continued to develop at a high speed, people's living standards have improved significantly, and the demand for animal products has also increased. People have paid more and more attention to nutrition and health. High-protein and low-fat eating habits are deeply rooted in the hearts of the people. requirements are also getting higher. In order to cater to market demand and seek high profits, some illegal breeding enterprises and farmers disregarded national regulations and mixed "clenbuterol" into the feed in order to prevent pork from growing fat. After eating, pigs promote protein synthesis in the metabolic process, accelerate the conversion and decomposition of fat, an...

(3) Increase the reproduction of harmful bacteria in the back of the intestinal tract, increase the water content of the feces, make the breeding environment worse, and increase the chance of disease occurrence

[0019] 2. Cause an immune response in animals

[0020] β-mannan will over-stimulate the immune response in the incomplete development of intestinal cells in livestock and poultry, or in a stressful environment, causing damage to growth performance, causing adverse immune reactions, decreased food intake, and slower growth, resulting in The number of underweight increases and the population uniformity becomes worse
