Problems solved by technology

On the other hand, since two hens are kept in one cage at the same time, it is impossible to judge which one of them lays eggs each time, which leads to some low-yielding pigeons, which cannot be found due to the high yield of the "spouse"; Also in future laying pigeon breeding, there is no way to implement selection based on individual egg production, slowing down genetic progress

Embodiment 1

[0023] The young pigeons mixed in the same batch of flying sheds have been sexed, and the hens wear red anklets. At the age of 5 months, 30 male pigeons and 60 female pigeons were randomly selected. Among them, 30 cocks were paired with 30 hens; the other 30 hens were kept in single cages, and the cages were completely covered with cardboard, so that physical contact could not be formed between the pigeons. Pigeon cage distribution position, feeding management is the same. Egg production was recorded for each cage. And transferred to flying shed (2 months old), before pairing (before basketing, 4 months old), male and female pairing (after pairing, before laying eggs, 5 months old) and single hen (5 months old, 6 months old) 7-month-old, 7-month-old hens were subjected to wing vein blood collection, and serum was separated to determine gonadotropin-releasing hormone (GnRH) and gonadotropin-inhibiting hormone (GnIH).

[0024] The results of hormone measurement are: the level...

Embodiment 2

[0031] The sexes are done and the hens wear red anklets. The same batch of 1,000 baby pigeons, including 200 cocks and 800 hens, were transferred to flying sheds for breeding. There are 100 male pigeons in each room, and 200 hens in each room, and they are distributed in the order of female, male, female, female, male, female... at intervals. At the age of 5.5 months, 96 cocks and 288 hens were randomly selected, transferred to the egg-laying loft, and the experiment was started. Three groups of male and female pairing (G), double female pairing (S), and single hen (D) are set when basketing, and 4 repetitions are set for each group, and 24 pairs are each repeated (for the single hen group, each repetition 24 only). The distribution position of each group of pigeon cages, the feeding management is the same. Record the egg production situation, the number of eggs laid and the number of broken eggs of every cage pigeon are recorded separately, based on the single cage data, t...

Embodiment 3

[0043] The sexes are done and the hens wear red anklets. The same batch of 2,000 baby pigeons, including 400 cocks and 1,600 hens, were transferred to flying sheds for breeding. There are 100 male pigeons in each room, and 200 female pigeons in each room; there are 10 rooms in total, 2 rows, and each row is distributed in the order of female, male, female, female, male, female.... At the age of 5.5 months, randomly select 80 cocks and 1500 hens, transfer them to the egg-laying loft, and raise them in single cages. The cocks are scattered among the hens, the more even the distribution in the loft the better. Record the egg production situation, the number of eggs laid and the number of broken eggs of every cage pigeon are recorded separately, based on the single cage data, the average value of each group is counted every month.

Abstract

The invention relates to a method for raising egg-laying pigeons in a single cage, which comprises the following steps: (1) before young pigeons are transferred into a flying shed, female pigeons are marked; in the flying sheds, young pigeons are subjected to group flying breeding, 15%-25% of young male pigeons are placed in each flying shed, the male pigeons and the female pigeons are bred in different rooms, and the male pigeon breeding room is adjacent to the female pigeon breeding room; (2) feeding young female pigeons to 5.5-6 months old, and transferring the young female pigeons from the flying shed to a pigeon house for pigeon feeding; in the pigeon house, the pigeons are raised in a single cage, and no less than 5% of male pigeons are scattered and distributed in each pigeon house.

Description

technical field [0001] The invention relates to the field of poultry breeding, in particular to a method for raising laying pigeons in a single cage. Background technique [0002] Pigeons belong to monogamous birds. Once the male and female pigeons are successfully paired, they have high loyalty. Except for special circumstances (one party dies), they will accompany them for life and undertake the task of hatching and feeding the pigeons together. Early studies found that pigeons cannot spontaneously ovulate, and need to be stimulated by male and female pigeons to lay eggs. After research, it was found that in the absence of males, after two female pigeons caress each other and imitate mating, both female pigeons can lay eggs, so the breeding method of "double female pairing" to raise egg-laying pigeons was born in production. The egg production is more than 1.5 times that of the "male-female pairing" mode. However, because the "double-female pairing" pigeons still have "m...
