Artificial breeding technique of Chinese partridge

Partridge, also known as Chinese partridge, is a kind of bird. The wild reproduction rate of partridges is very low, and the artificial breeding of partridges has not been successful. So how to raise Chinese partridges? Let's take a look at it with the editor.

Artificial breeding technique of Chinese partridge

1. Laying eggs. Wild partridges generally lay eggs and breed from March to June, which belongs to seasonal breeding. The laying rate of artificial breeding is almost the same as that of wild partridges, and the laying rate is very low. Under good control conditions, the breeding season is prolonged. However, it is impossible to lay eggs all the year round, and the annual egg production is about 20. The reproductive performance of partridges is affected not only by parental genetic factors, but also by external environment, such as nutrition, management and other factors.

two。 Sexually mature. The sexual maturity of female partridges is earlier than that of male partridges. The sexual maturity of female partridges is 200-240 days, and that of male partridges is 2-3 weeks later. Therefore, it is necessary to increase nutrition and light in advance for male partridges.

3. Pairing. In wild conditions, it is a male-female pair, artificially domesticated, but a male-female group, using the way of free mating.

Selection and mating of breeding partridges

In order to breed successfully, in addition to learning the sex identification of partridges, seed selection is particularly important. Among the fine varieties, strong, large and mobile partridges should be selected for seed selection. In order to avoid inbreeding, it is necessary to exchange species with other farmers. Breeding partridges should be eliminated after 90 weeks of age, otherwise their fecundity and productivity will be affected. Mating is generally carried out in the following two ways, namely, cage mating and indoor mating. Cage mating: put a male and a female in a 0.4 square meter cage and allow it to mate freely, which is helpful to observe the mating situation, that is, to quickly identify unfertilized males or unfertilised females, so as to supplement males or females in time. Indoor mating: male and female breeds are usually mated freely in a spacious and bright shed or in a cage with a ratio of 1 ∶ 3. The best time to mate is after breakfast. Wild partridges lay eggs once a year, laying 10-20 eggs. Light can promote the breeding of partridges to be illuminated by electric lights for 17 hours a day, and the number of eggs can reach 120. At present, flying net rooms or other open houses in China make use of natural daylight during the day, and the insufficient lighting time can be supplemented by artificial illumination according to the lighting system.

Management and hatching of breeding eggs

During the laying period of partridges, the breeding eggs laid by partridges should be collected and preserved in time, at least 3-5 times a day. When the weather is too hot or too cold, the number of collecting times should be increased. The breeding eggs should be placed on the egg plate, with the big end up, and then the breeding eggs should be moved to a room with a temperature of 12-16 ℃, relative humidity of 70%, relatively ventilated and cool, clean and hygienic. Generally speaking, the storage period should not exceed 15 days, and the expiration will affect its hatching rate. The incubation period of partridge eggs is about 23-24 days, with a general hatching temperature of 37.5 ℃ and a relative humidity of 50% and 70%. The hatching method of partridge eggs is basically the same as that of eggs. After 21 days of incubation, there is no need to turn the egg plate. There is no need for artificial midwifery when hatched chicks are moved to hatchling warmers, because such weak chicks and healthy ones will cause each other to peck.

Disease prevention and control of partridge

For disease prevention and control of partridges, we must adhere to the important principle of "prevention first, prevention is more important than cure". In order to implement this policy, the following comprehensive epidemic prevention measures should be taken.

1. The choice of the site, the design of the chicken house, the reasonable layout of the building, the supply of nutritious and comprehensive feed, and the cultivation of strong species of partridges.

two。 Keep a clean breeding environment to prevent the spread and spread of pathogenic microorganisms.

3. Scientific immunization procedures and timely planned immunization, as well as quarantine, surveillance, diagnostic isolation, disinfection, drug prevention, elimination and strict handling of dead bodies.

4. Attention should be paid to the prevention and treatment of Newcastle disease, pullorum, coccidiosis, avian cholera, avian influenza, infectious bronchitis and vitamin deficiency.

As mentioned above, we should select good species of partridges, pay attention to diet and feeding environment, and make preparations for epidemic prevention, so that the herds will get less or no disease, so as to ensure the sustained, stable and healthy development of partridge production and obtain good economic benefits.
