Application of catechin to preparation of animal feed additive and feed thereof

Abstract

The invention provides application of catechin to preparation of an animal feed additive and feed, the catechin is one or more of epigallocatechin gallate, epigallocatechin, epicatechin and epicatechin gallic acid, and the catechin is applied to preparation of the feed additive for improving the physique of newborn animals. When the catechin animal feed additive is applied to prepare a catechin feed, the addition amount of catechin is 0.05-20% based on the total mass of the feed, nutrient element absorption of a parent body is increased, nutrient element absorption of a daughter in the parent body and formation of an immune system are promoted, nutrient element storage of the daughter is increased, the physique of a newborn animal is improved, the weight of the newborn animal is increased, and the survival rate of the newborn animal is increased. The survival rate of newborn animals is improved.

technical field

[0001] The invention relates to the technical field of animal feed additives, in particular to the application of catechins to prepare animal feed additives and feed thereof. Background technique

[0002] Animal husbandry is an important part of the basic agricultural industry. Its level of development is directly related to the level of agricultural production. It is an important symbol of a country's national living standards. The proportion of animal husbandry production in developed countries to agricultural production is 50%. For example, the United States accounts for 50.1%, the United Kingdom accounts for 59.8%, and countries with relatively developed animal husbandry, such as New Zealand and Australia, account for more than 70% of agriculture. And my country's animal husbandry output value only accounts for about 35% of agricultural output value, so my country's vigorous development of animal husbandry just seems a long way to go. There are many prob...
