How should black chickens be raised? (key points of feeding and management of farmed black chickens)

Black chicken, also known as black bone chicken, Wushan chicken, has a history of more than 400 years. There are white hair black bone, black hair black bone, spotted hair black bone, flesh and blood black, flesh white bone black. Black chicken has the characteristics of light body, rich nutrition and early maturity. So how should black chickens be raised? What are the management techniques for raising black chickens?

First, the characteristics of black chicken

The black chicken belongs to the bird class, with a whisker under the chin, blue ear leaves and white feathers. Except for the arrow-shaped feathers of the wings and tail feathers, they are all velvety. The male is a mulberry-shaped purple-black round crown with fine hairs behind the crown. The female wears a white velvet ball on her head and has many short hairs on her upper jaw and cheeks. The claw is divided into five toes, that is, an extra toe on the back finger, with hairy feet and dense metatarsal hairs. Because the viscera and fat of black chicken are black, it is called black chicken.

II. Key points of management

1. Meticulous breeding

When chicks are just hatched, they must be kept warm. The optimal temperature is 35-36 °c in the first week, 32-34 °c in the second week, and then reduced by 2 °c per week. The temperature can drop within 5 to 7 weeks. After 2 days of age, if 1/3 of the chicks are found to eat with their beaks, they can start eating. A few days before the meal, half-cooked millet was fed and mixed with cooked egg yolk, the amount of egg yolk was 1 for every 18 chicks per day, and 7 days later, mixed feed was used, which was mainly based on dilute grains, supplemented with vegetables, fish meal and vitamins. When breeding, about 17 animals can be raised per square meter, drinking water should be clean enough, warm water should be eaten as early as possible, and 1/10000 potassium permanganate should be added.

two。 Adult chicken rearing

The nestling grows faster, grows silk hair at the age of 30 and weighs up to 250 grams at 50 days. Usually keep the chicken coop hygienic, with proper humidity and adequate drinking water. The lights are kept for 16-17 hours a day during spawning. When the light is insufficient, it must be replenished manually. Daily consumption of 10% fish meal, 10% bean cake, 20% flour, corn (23162.00 0.09%) powder 30%, sorghum 5%, rice bran 7%, shell powder 2%; auxin 1%, green feed 15%. The combination of dry and wet feeding was used. Four or five times before April. In the process of spawning, feed more green fodder to prevent excessive fat from spawning, and properly add manganese salt to improve the yield and quality of eggs.

3. Prevention and treatment of epidemics

Although Wuji has strong disease resistance and fewer epidemics, it should also adhere to the principle of "early prevention and early treatment". Clean the chicken coop every day, remove feces, pay attention to moistureproof; disinfect once a week, scrub the disinfection trough every 3-5 days; do not feed moldy feed.

4. Reproductive selection

The breeding of black chicken must choose excellent individuals with five characteristics: double crown, green ear, white velvet, five claws and black. Hatching can be done in spring and autumn, but it is best to hatch in spring. Roosters need strong and obvious sexual traits; hens require more eggs and less nesting sex. The proportion of breeding cocks is 1:6, you can get a higher fertilization rate, and the hatched chicks are also very strong. Roosters can breed from June to July. Hens are better in October and can be used for 3-4 years.

III. Scientific breeding techniques of Black Chicken

1. Full-in-all-out reproduction

The flat surface is scattered, and the cushion material is changed once in the middle. According to the building area to determine the number of breeding, sales are mainly wholesale. After sale, the empty bar will be sterilized for one week and the next batch of culture will be carried out.

two。 Separate feeding

Use two or more relatively separate houses, one as a nursery and one as a growing room. After grouping, disinfect the empty column for about 1 week, and then enter the seedlings. The first batch was bred and all went out (or sold out in a short period of time), mainly wholesale. After sale, the empty strips will be sterilized for about a week before the next batch of culture.

3. Retail-based sectional feeding

Three or more relatively independent rooms were divided into nursery, early growth room and late growth room, with an area ratio of 1:2:4. The seedling group was transferred to the early growth house for 25-30 days. After the transfer of the group, disinfect the empty column for more than 1 week, and then enter the chicks; in the first 30 days, and then switch to the later growth house. After the conversion, the empty column was disinfected for about 1 week and raised. In the later stage, about 20 days of breeding began to be put on the market, mainly for retail. The weight of each chicken should be more than 1 kg, and the selling period was about 10 days. The whole chickens that could not reach the sales weight after 20 days were discarded and disinfected in empty columns to prepare for herding. In this way, the batch feeding volume is 20 times of the average daily sales volume.

IV. Environmental hygiene of breeding farms

1. Pay attention to ventilation, diligently change gaskets, reasonable ventilation, can promote the development of cardiopulmonary system. Change the gasket carefully to ensure the cleanliness and hygiene of the chicken coop; usually change the gasket once every 10 days, and the gasket that is wet by water will be replaced immediately.

two。 In terms of environmental hygiene, we should take regular epidemic prevention measures in and around the chicken house, and persist in using disinfectants to disinfect the chicken in the chicken house and its surrounding activities every week.

3. Pay attention to biosafety pay attention to check whether there is a rat hole in the chicken house and plug the rat hole in the chicken house in time. Take effective measures to prevent the harm of cats, dogs, rats and birds to chickens and reduce the spread of diseases.
