How to raise black-bone chicken breeding techniques and matters needing attention

When it comes to raising chickens, I believe many people have raised several chickens at home! In fact, there are many varieties of chicken, black-bone chicken is one of them, black-bone chicken is very special, because it is black, it is easy to identify, and its eggs are green, also known as green-shell eggs. Do you know how to breed chicken?

How to raise black-bone chickens

1. Disinfection and rat prevention: Before brooding, the ground and walls of the brooding room should be sprayed with 2000:1 hundred poison S or ABB disinfectant for disinfection, and then the trough should be washed clean and dried for later use. At the same time, the brooding room should have a cement wall half a meter high, and rat holes are strictly prohibited.

2, heat preservation and humidity control: due to the chicken hair thin short, can not cold, can not adjust the temperature itself, the temperature is too low will cause the growth of chickens blocked, pile up extrusion, leading to the outbreak of white dysentery; if the humidity is too large, will lead to coccidiosis, so to ensure reasonable brood temperature and humidity. Brood room should be equipped with thermometer, always grasp the brood room temperature.

The temperature and humidity of the brood room are generally 34℃ to 32℃ and 65% to 60% for chickens under 1 week of age; 32℃ to 28℃ and 65% to 60% for chickens between 1 and 2 weeks of age; 27℃ to 25℃ and 65% to 60% for chickens between 2 and 3 weeks of age; 25℃ to 23℃ and 60% for chickens between 3 and 4 weeks of age; After 4 weeks, the temperature is about 20℃ and the humidity is 60%.

3, drinking water to eat: chicks out of the shell 20 hours later, you can enter the brood room, first drink water, then eat. Start drinking water application 5% to 10% white sugar water, drink half a day, can improve the survival rate. Chickens before 10 days of age should drink warm boiled water at a temperature close to room temperature. The best way to drink water is to use a chick drinking water dispenser, which should always maintain constant water, so that chicks can drink freely. After drinking water for 2 to 4 hours, you can start eating. Soak the feed in water, disperse it as soon as you catch it, and sprinkle it evenly on the plastic cloth to let the chicks eat freely. The feed can be fed directly to the complete feed produced by the feed factory. However, no matter what kind of feed is fed, for the first 3 to 5 days, 0.2% chloramphenicol or 0.2% sulfamethazine must be added to the feed, or broad-spectrum antibiotics such as ofloxacin must be added to the drinking water to control the occurrence of pullorum disease.

1. Feeding points during brood period

Chickens must be kept warm when they hatch. The optimum temperature was 35℃~36℃ at 1 week old, 32℃~34℃ at 2 weeks old, and 2℃ lower every week thereafter. The temperature could be removed at 5~7 weeks old. Chicks 2 days old, such as the discovery of one-third of the chicks with beak pecking phenomenon can be opened to feed. Feed cooked millet for the first few days and mix it with cooked egg yolk. The amount of egg yolk can be 1 per 18 chicks per day. After 7 days, mixed feed was fed, mainly semi-ripe grain, supplemented with vegetables, fish meal and vitamins. The density of brood was about 17 per square meter. Drinking water should be sufficient and clean. Warm water should be fed at the initial stage. One thousandth of potassium permanganate should be added to the water.

2. Feeding points in laying period

To keep the air in the chicken house fresh, humidity appropriate, provide adequate and clean drinking water. During the laying period, keep 16~17 hours of light every day. When the light is insufficient, it should be supplemented manually. The ration should adopt compound feed, among which fish meal

10%, bean cake 10%, grain flour 20%, corn flour 30%, sorghum 5%, rice bran 7%, shell powder 2%, auxin 1%, green feed 15%, dry and wet combined feeding method. 4 months old. The day before yesterday.

4 - 5 times. During the laying period, green and juicy feed should be properly fed to prevent laying hens from being over-fat. Adding manganese salt properly can improve egg production and egg quality.

Living Habits of Black-bone Chicken

Black-bone chickens grow and develop rapidly. Black-bone chickens of the same age from shell to 13 weigh 10 to 30 times as much as their birth weight. The weight of adult black-bone chicken is 33~40 times of birth weight. The digestive ability of black-bone chickens is relatively poor. Pheasant stomach small, weak digestion of crude fiber, diet, should be easy to digest, high nutrition, low crude fiber feed is appropriate. Black-bone chickens have poor disease resistance and are vulnerable to various diseases. The ability to regulate body temperature is also poor. Especially chicks. Small, delicate and susceptible to environmental conditions.

0~7 days old chicks, body temperature is only 39.8℃, 1-2℃ lower than adult chickens, both afraid of cold, but also afraid of heat. Black-bone chickens are strong in nesting, some individuals wake up 25 days after nesting, but individual differences are large. The shorter the nesting time, the higher the egg production, conversely the less. Black-boned chickens are sensitive and timid, especially chicks, which are extremely sensitive to external reactions.

What are the advantages of chicken?

2. Black-bone chicken has high nutritional value, low cholesterol content, rich in amino acids, melanin and free fatty acids, etc., which can increase the heme content of human red blood cells, regulate physiological functions and enhance immunity. It is an ideal food for nourishing and medicinal purposes. With the improvement of people's living standards, the consumption of black-bone chicken as a black nourishing food will increase.
