Description

Technical Field

[0001] The invention belongs to the technical field of feed, and in particular relates to a composite premixed feed for meat and egg dual-purpose chickens and a preparation method thereof. Background Art

[0002] With the development of animal husbandry, dual-purpose chickens, as an important poultry breeding variety, have received more and more attention for their production performance and economic benefits. However, there is no standard for the breeding of dual-purpose chickens. In the traditional breeding process, broiler feed is mostly used for feeding in the brooding stage, which is extremely unfavorable for the body development in the rearing stage and will also cause nutritional metabolic diseases; in the rearing and egg-laying stages, high-yield laying hen feed is mostly used for feeding, which is easy to cause fatty liver disease, also known as fat syndrome. In mild cases, egg production is reduced by 30-40%; in severe cases, sudden death occurs in an extremely good state of body condition, and body fat increases, and the meat quality of the hens that are eliminated is poor. Therefore, the development of an efficient, balanced, nutritionally comprehensive, and special composite premixed feed for dual-purpose chickens is of great significance for improving the production performance, meat quality and economic benefits of dual-purpose chickens.

[0003] There are many kinds of feeds on the market, but there is no special compound premixed feed for dual-purpose chickens. To meet the special nutritional needs of dual-purpose chickens for meat and egg production, we invented a special compound premixed feed for dual-purpose chickens and a preparation method thereof.
