Problems solved by technology

At present, livestock and poultry breeding mainly use corn-soybean meal-based feed. Studies have shown that the utilization rate of protein in the feed for pigs is only about 30%, and that for broilers is about 45%. Monogastric animals excrete 70% of the phosphorus in the feed. This not only causes waste of nutrients and reduces the production efficiency of breeders, but also causes great harm to the environment

Embodiment Construction

[0028] The technical solution of the present invention is as follows: The technical solution of the present invention is as follows: Utilize in vitro digestion test, measure the digestibility of different enzyme preparation combinations to feed, screen most have enzyme preparation combination, thereby determine compound enzyme preparation prescription, finally according to inventor And other novel compound enzyme preparations prepared by using the technical scheme of the present invention, the experiment of raising livestock and poultry proves that adding the novel compound enzyme in poultry feed can increase weight gain by 5-15%, improve egg production by 5-15%, and reduce feed consumption by 5%. ~15%. The use of this enzyme in pig feed can increase the weight gain by 5-15%, and the feed weight gain ratio can be reduced by 5-15%.

[0029] Various enzyme preparations used in the present invention have their respective biological functions. Soybean meal is the main protein raw...

Abstract

A composite enzyme product as the additive of forage for domestic animals and fowls to increase the utilization rate of forage and the resistance to diseases, promote growth, and decrease the contents of organic substances, N, P, etc in excreta is proportionally prepared from beta-glucosidase, glycanase, beta-mannase, neutral phytase, acidic phytase, neutral proteinase, acidic proteinase, antioxidant, anti-mildew agent, insect repellent and carrier. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to an animal feed additive and a preparation method thereof, in particular to a novel compound enzyme preparation for livestock and poultry and a preparation method thereof. Background technique [0002] With the continuous improvement of people's health and food safety awareness, the focus of the production of livestock and poultry products has shifted from pure quantity to quantity and quality development, and the increasing attention to safety and function has become the key to the sustainable and healthy development of animal husbandry; the environment Conservation is increasingly becoming an issue of growing concern. At present, livestock and poultry breeding mainly use corn-soybean meal-based feed. Studies have shown that the utilization rate of protein in the feed for pigs is only about 30%, and that for broilers is about 45%. Monogastric animals excrete 70% of the phosphorus in the feed. This not only causes waste of nutr...
