Cage applicable to brooding growing period breeding of laying hen parent generation reserve cock and breeding process of cage

Abstract

The invention discloses a cage applicable to brooding growing period breeding of laying hen parent generation reserve cock, and a breeding process of the cage. The cage is of a three-layer overlapped structure for brooding growing period breeding of laying hen parent generation reserve cock of 1 day to 18 weeks old, and comprises three case bodies and three layers of cage shelves, wherein the cage bodies are vertically placed on the three layers of cage shelves; the cage bodies are 160cm, 160cm and 62cm in length, width and height; the cage bodies comprise top nets, bottom nets as well as first side nets, second side nets, third side nets and fourth side nets which are connected in sequence; two door nets are respectively arranged on the first side nets and the third side nets; feed troughs are formed in the lower parts of the side nets of the door nets; and two vertical long grids for holding water tubes are arranged at 1 / 3 parts extending inwards in axial directions of two side beams on the second side nets and the fourth side nets. According to the characteristics of growth and development of the reserve cock, the specification of the cage is increased, and on the premise that the breeding density is not changed, the relative activity space of chicken is increased, so that the growth and the development of the brooding growing period reserve cock can be effectively promoted, and the breeding efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a cage suitable for the rearing and growing-up cultivation of laying hen parental roosters and a breeding process thereof. Background technique [0002] The insemination ability of a breeder rooster is one of the important factors that determine the hatching performance of a breeder chicken farm. The level of breeding management of a breeder rooster has an important impact on the insemination ability of a breeder rooster and the production performance of its offspring (Key Points of Breeder Rooster Management Techniques, "Shandong Poultry" , No. 10, 2003). Standard body weight and good skeletal development are the basis for cultivating excellent roosters and maintaining excellent fertilization rate to the greatest extent during the laying period of hens (Management of Breeding Roosters, "Foreign Animal Husbandry-Pigs and Poultry", 2006, p. 26, No. 3). 85% of the skelet...

AI Technical Summary

Problems solved by technology

Since the size and weight of parent breeder chickens of laying hens are significantly different from those of broiler breeders, generally the size of the reserve chicken cages is that the length, width and height of a single cage are less than 1 meter, with 3 to 4 layers, and the front and back of the same layer correspond to each other. There is a net between the two single cages. If the group is not expanded in time, the stocking density will be reduced, which will easily limit the activity space of the chickens, reduce the activity of the reserve roosters, easily hinder the growth and development of the chicken bones, and reduce the physical fitness of the reserve roosters.

[0004] Therefore, in order to overcome the small size of the single cage of the chicken cage in the parent chicken farm of the layer hen at present, which affects the growth and development of the male hen, it is necessary to improve the cages and the breeding density of the reserve chickens of the parent generation of the layer hens cultivated in one stage. Optimize to increase the relative activity area and welfare level of roosters in chicken cages, improve the breeding effect of reserve roosters, improve the insemination ability of roosters throughout the breeding cycle and the production efficiency of breeder farms
