Preparation method of composite feed using grass to replace grain

Abstract

The invention aims to overcome the shortages of bad palatability and weather limitation of green feed made of fresh wormwood, and provides a composite feed. The composite feed is developed on the basis of wormwood, and is processed and improved by adding other auxiliary ingredients into the wormwood. The composite feed for poultry and livestock is rich in nutrients, is palatable, is not affected by the weather, and can be produced all year long, and a great amount of grain is saved. The green feed made of wormwood can only be produced in the growing and mature period of wormwood (May to October), in order to utilize the wormwood with a high nutrient value, the fresh wormwood is cut off in the growing and mature period, then the fresh wormwood is dried by baking or sun immediately, the dried wormwood is pulverized into wormwood powder, the wormwood powder is taken as the matrix; auxiliary materials such as straw powder, which has been processed by a biological feed agent for preparing, meal cake, a little amount of grain, and shell/bone meal are added into the matrix to produce the composite feed, which is mainly prepared from wormwood.

Description

technical field [0001] The invention relates to an animal feed, in particular to a compound feed for livestock and poultry which is processed with wormwood as a substrate and straw, cake, grain and shells. Background technique [0002] Every year in raising livestock and poultry, a large amount of food needs to be consumed, especially in China, which is a country with many people and little land. The contradiction between humans and animals competing for food has become more and more prominent and has attracted attention to seek feed instead of food. At present, the compound feed used in the breeding industry, in its composition, grain accounts for 60-70%. Although a small amount of amino acids, trace elements and other nutrients are added to the composition, the fillers such as bran are still poor in nutrition. Ingredient, although the added growth promoter can accelerate the growth rate of livestock and poultry, the taste of meat and eggs of livestock and poultry (such as ...
