Feed for chickens

Abstract

A feed for chickens takes yellow mealworms as a new resource of animal protein, takes lutein as a feed additive, and is formed by matching sweet corns, yellow mealworms, bean pulp, lutein, dibasic calcium phosphate, premix compound, salt, fine aggregate and wheat barn, wherein the metabolizable energy is 2850-2900 kcal/kg, the protein is more than or equal to 19.5%, Ca accounts for 0.9-1.2%, total phosphorus accounts for 0.6-0.8 %, methionine is more than or equal to 0.48%, and lysine is more than or equal to 1.15%. In the invention, compared with the feed taking the bean pulp as a main material, the immunity of poultry and the function of the immune system are improved, the immune cells are activated overall, the generation of the antibody is promoted, the occurrence rate of diseases is decreased, and the precipitation capacity of the lutein in the egg yolk is improved greatly, the mouthfeel of eggs, the laying rate and egg quality of the chickens are improved, the egg laying peak season is prolonged, the single egg weight is increased, the color of the egg shell is bright, the nutritional value is higher, the laying rate is improved by 4%, the mortality and elimination rate is reduced by 4.5%, the feed is saved by 14%, and the economic benefit is improved by 4.3%.

Description

technical field [0001] The invention belongs to the technical field of feed for poultry breeding, and in particular relates to a chicken feed. Background technique [0002] Chickens need a lot of energy and a variety of nutrients in the process of growth and development. If the feed energy is insufficient or lacks certain essential ingredients, it will cause problems in the body's metabolism, resulting in slow growth and development, weight loss, decreased immunity, and egg production. rate and egg quality will decrease significantly. At the same time, with the improvement of people's living standards, the quality requirements for eggs have also increased. Eggs with good egg quality, no fishy smell, good taste, smooth and reddish skin are very popular in the market. [0003] At present, chicken feed mainly includes corn-soybean meal-fish meal feed, corn-soybean meal-type feed, corn-soybean meal-miscellaneous meal feed and corn-soybean meal-fish meal-other animal protein fee...

[0002] Chickens need a lot of energy and various nutrients in the process of growth and development. If the feed energy is insufficient or lacks certain essential components, it will cause problems in the body's metabolism, resulting in slow growth and development, weight loss, decreased immunity, and egg production. The rate will decrease, and the egg quality will also decrease significantly.
