Problems solved by technology

[0004] However, the cross-cage breeding mode is still in its infancy, and there are still many problems worth noting, especially during the long-term cross-breeding process of male and female hens. The hen's back injury and feather loss caused by the rooster's toe tip (claw) during the long-term inbreeding process of the male and female hens will affect the breeding chickens. egg production performance

Embodiment 1

[0017] The toe tips of the second and fourth toes of the Hailan brown parent chicks should be cut off at the age of 1 day. The toe cutting operation should be thorough, and the bones and skin of the toes of the male chicks should be avoided. At the age of 90 days, the roosters and hens were transferred to the cages for breeding according to the male-to-female ratio of 1:12.

[0018] Divided 96 toe-amputated roosters (toe amputated by electric beak trimmer at 1 day old) and 230-day-old Hailan brown parent roosters into 4 groups. , Severing the first and third toes, Severe the second and fourth toes. Each group is divided into 1 repetition based on 1 individual cage, and there are 6 repetitions in total, and each repetition includes 4 Hailan brown parent roosters and 48 hens. The experiment started on December 22, 2015 and ended on January 31, 2016, a total of 40 days. Record the number of eggs per day and the number of dead male and female hens for each repetition in each...

Abstract

The invention relates to a method for improving the egg laying performance of natural-mating cage-raising breeding hens. The method comprises the steps that one-day-age male chicks are taken, the tiptoes of the second toe and the fourth toe of each male chick are broken, and the male chicks and female chicks are put into a natural-mating cage in proportion to be raised, wherein toe breaking operation is conducted through an electric heating poultry debeaker and needs to be thorough, and the bones and the skin of the toes of the male chicks are prevented from being damaged. The method is simple, easy to operate and high in applicability; the defects of a natural-mating cage-raising mode are effectively avoided, so that the egg laying rate of the breeding hens is increased by 5% or above; the method can be applied to large-scale raising of parent-generation breeding hens with the high egg laying yield.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for improving the egg-laying performance of the breeding hens raised in cages. Background technique [0002] From the middle of the 1980s to the beginning of this century, the advantages of my country's labor resources have led most breeder farms to adopt artificial insemination technology. Therefore, artificial insemination technology has played a vital role in the construction of my country's poultry breeding system. In recent years, with the increase of artificial labor costs and the continuous promotion of the concept of animal welfare, the shortcomings of artificial insemination technology, which is mainly characterized by labor-intensive, have emerged. 1. Improper insemination operation caused cloacal damage and increased vertical transmission of germ-derived diseases. In this context, the cage breeding mode of breeder chickens, which is mainl...
