Feed specially used for feeding pink shell layer chicken in laying period

Abstract

The invention discloses feeds specially used for feeding a pink shell layer chicken in a laying period. The basis of preparing the feeds is nutritional parameters of diet of the pink shell layer chicken. The feeds are formed by raw materials such as corns, soybean meals, bran, cottonseed meals, rapeseed meals, fish meals, yeast powders, dicalcium phosphate, stone powders, shell powders, vegetable oil, microelement additive, compound vitamins, choline, salt, methionine, lysine, and the like through series test in an optimizing proportioning way, and are respectively suitable for a pink shell layer chicken of 21 to 40 weeks old (egg laying peak) and a pink shell layer chicken of 41 to 78 weeks old (egg laying middle-late stage) to carry out feeding utilization. The prior feeds which are prepared according to a nutrition standard of a white or brown shell layer chicken are respectively used to feed pink shell layer chickens in the laying period, and are determined through comparison that the egg production of a housed chicken of 78 weeks old is enhanced by 8.3 percent; the feed-egg ratio benefit is enhanced by 9.8 percent, nutritional metabolic diseases are lowered by 53.4 percent; and the chicken mortality is lowered by 3.5 percent, and the net income is increased by 65.4 percent.

Description

technical field [0001] The invention belongs to the animal husbandry technology in the agricultural field, and relates to a feed specially used for feeding powder-shell laying hen series breeds during the laying period. Background technique [0002] Due to its soil-like characteristics, high market price, good breeding benefits, strong disease resistance, and significantly lower fishy smell than brown-shell eggs, powder-shell layer hens have been widely used in my country in recent years. Faster, currently more than 400 million. However, pink-shell hens are hybrid offspring of heavier brown-shell hens and lighter-weight white-shell hens. Their physical characteristics such as body shape and basal metabolism are different from those of brown-shell hens and white-shell hens. Chicken has its unique characteristics of growth and development and nutrient metabolism requirements. However, due to the lack of systematic research on the nutritional needs of powder-shell hens in curr...

AI Technical Summary

Problems solved by technology

However, due to the lack of systematic research on the nutritional needs of powder-shell hens in current production, the rations are basically prepared using the nutritional standards of white-shell or brown-shell hens, and there is no special compound feed for powder-shell hens. As a result, the growth and development of powder-shell hens is difficult to reach the standard, and the inherent production potential cannot be effectively exerted

The applicant found during the production investigation that: the ration prepared by using the nutrient standard of white-shell hens for powder-shell hens has a high level of main nutrients and is easy to induce metabolic diseases; the ration prepared by using the nutrient standard for brown-shell hens, Its main nutrients, especially the low energy level, are difficult to meet its normal needs. At the same time, it is easy to convert the high-priced protein in the feed into energy through the gluconeogenesis pathway, resulting in waste of protein feed resources.
