Problems solved by technology

The feed conversion efficiency of broiler chickens of AA+ and Ross308 breeds is lower than that of Kebao breeds, and their body weight standard and the development degree of each growth stage are different from those of Kebao breeds, and their feeding technology cannot be applied to the breeding of Kebao breeds; The feeding technology does not take into account the impact of more domestic diseases and immune stress on the growth and development of breeders, and does not consider many factors such as domestic feed nutrition levels are lower than the actual situation in the United States, so the technical solution of the American Kebao company is used , it will lead to problems such as difficulty in normal start of laying, low egg production peak and rapid decline in egg production in the late stage of laying

Embodiment Construction

[0018] The present invention will be described in further detail below.

[0019] The present invention relates to a breeding method for broiler breeders of Kebao parents. Based on the feeding mode of flat rearing, the body weight standard and the egg production rate index of the breeder chicken are formulated according to the age of the breeder chicken of this breed, and according to the standard and the index, At different ages, cocks and hens were given different lighting durations and intensities, and different amounts of feed.

[0020] Before the age of 30 weeks, the method of increasing the amount of feed for the hens is adopted, and after the age of 30 weeks, the method of reducing the amount of feed for the hens is adopted.

[0021] During the first week to the fourth week of the hen, the brooding feed was fed; the feed amount of each hen in the first week was 21 grams, and the body weight was 140 grams; in the second week, the feed amount was increased to 28 grams, and...

Abstract

The invention discloses a Cobb parental broiler breeding chicken feeding method. Based on a feeding mode of flat feeding, according to the week age of breeding chickens, indexes of the weight standardand the breeding chicken laying rate of the breeding chickens are set, and according to the standard index, different lighting durations and intensity and different feed feeding quantities are applied to the cocks and the hens at different week age; before 30 week age of the hens, a mode of increasing the feed quantity is adopted, and after 30 week age, a mode of decreasing the feed quantity of the hens is adopted; and by accurately controlling the weight of the breeding chickens in all week age periods, the weight and laying rate of the breeding chickens are dually controlled, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of breeding white-feathered broiler breeders, in particular to a method for raising Kebao parent generation broiler breeders. Background technique [0002] At present, there are many breeds of broiler breeders on the market, such as AA+, Ross308, and Cobb500. Among them, AA+ and Ross308 are varieties of American An Weijie Company, and Kebao is a variety of American Kebao Company. The feed conversion efficiency of AA+ and Ross308 broiler chickens is lower than that of the Kebao variety, and there are differences in their body weight standards and developmental degrees of each growth stage and the Kebao variety, and their feeding techniques cannot be applied to the breeding of the Kebao variety; The feeding technology did not take into account the impact of more domestic diseases and immune stress on the growth and development of breeders, and did not consider the fact that domestic feed nutrition levels and ...
