Breeding techniques of Wuhei chicken

Five black chicken is a rare rare bird in the world, also known as five black one green chicken, bright green black chicken, three Gorges black chicken, etc., with black hair, black skin, black meat, black bone, black viscera "five black" characteristics, tender meat, delicious taste, melanin has medicinal value, and contains a lot of lecithin, vitamins and trace elements, let's take a look at the five black chicken breeding technology!

Benefit of raising five black chickens

1. Breeding advantages: Wuhei chicken is mild-tempered, likes to live in groups, has strong disease resistance, and can be raised all over the country. The chicken has the advantages of fast growth, excellent meat quality, high yield, grain saving and high efficiency. it can be raised out of shell for 70 days up to 1 kg, and the feed cost is only 5.76 yuan (even lower in grain producing areas). The annual production of eggs is more than 180, the rate of green shell eggs is more than 85% under normal feeding conditions, and the weight of adult rooster is 1.5-2kg and that of hen is 1.2-1.5kg. It can be raised for more than 5 months, and the fertilization rate, hatching rate and survival rate can reach 85.95%. 2. Breeding benefit: under good feeding management, 50 groups (1 male and 5 female in each group) produce 45000 eggs a year, which can make a profit of at least 65000 yuan. If commercial chickens are bred, the most conservative breeding can be about 20, 000. Calculated on the basis of 30 yuan for each ordinary domestic chicken, the annual output value can reach 480000 yuan. After deducting all costs, it can make a profit of at least 250000 yuan, and its benefit is 10 to 20 times that of pig farming and dozens of times that of ordinary farming.

The site building of the chicken farm

1. Site selection: it is required that the terrain is high and dry, the drainage is good, the water source is adequate, the water quality is good, and the power supply is convenient, not less than 500 meters from the main highway and not less than 100 meters from the secondary highway.

2. The type of henhouse: closed type and open type.

3. The layout of chicken coop: according to the amount of feed, it should be beneficial to disease control.

4. Feeding equipment: according to local conditions (heating, ventilation, water supply, feeding, cages, lighting and other equipment).

Preparation work before brooding

1. Disinfection of the chicken house: prepare the brooding room before brooding, which requires heat preservation, airtight and rain-proof. One week before brooding, the brooding house should be cleaned, cleaned, fumigated with formalin and potassium permanganate or disinfected with Xiaoteling water.

2. Preheating in advance: one or two days before entering the chicken, the nursery should be preheated by laying bedding materials. The room temperature should reach 2729 ℃, and the temperature should be kept stable.

3. Facilities: prepare enough feed trough, drinking fountain and other utensils, choose high quality feed with comprehensive nutrition, and prepare enough drugs commonly used in chickens, such as anti-dysentery drugs, anti-coccidial drugs and disinfectants.

Feeding and management during the nestling period

1. Drink: chicks should drink first and then eat. Drinking should start as soon as possible to facilitate gastrointestinal peristalsis and yolk absorption, drinking water quality should be clean, warm boiled water should be used in winter, 1000 units of penicillin water should be used for drinking, and drinking water should be kept uninterrupted after opening. 2-4-day-old can drink 0.02% enrofloxacin water, stop the drug for 3 days after 3-5 days, and then use a course of treatment to prevent the occurrence of gastrointestinal diseases.

2. Eating: after drinking enough water, 2 / 3 chicks can eat when they have pecking behavior. After eating the feed, should choose nutritious high-quality chicken feed, to feed less frequently as the principle, a week later can feed some green fodder and gravel.

3. Temperature: temperature is the first condition for raising chicks. Hens can bring hatched chicks alive mainly depends on their body temperature to babysit chicks. When raising chicks on the ground, no matter in any season, bedding should be laid indoors, so that the abdomen of the chicken will not catch cold when sleeping. The temperature of brooding should be constant. The temperature of the first week is 3235 ℃, the room temperature is 2729 ℃, and then it decreases by 2 ℃ per week.

4. Humidity: humidity has a great influence on the health and growth of chicks, such as cold and cold chicks with high humidity and low temperature. However, if the humidity is too low, it will affect the absorption of yolk sac in the body. The humidity required by five black chickens is 60% 65% in the first week and 50% 60% after the second week.

5. Ventilation: the purpose of ventilation is to remove indoor dirty air in time, inhale fresh air and adjust the temperature and humidity in the house. Chicks should not only keep warm but also pay attention to ventilation to discharge toxic gases such as ammonia and carbon dioxide.

6. Lighting: a correct grasp of light is conducive to the consistency of the growth and maturity of chickens. Chicks can illuminate 24 hours in the brooding stage, and the light intensity should be 2-3 watts per square meter.

7. Density: density has a great influence on the growth and development of chicks, low density is uneconomical, and too high density will make chicks develop unevenly, slow down growth, be susceptible to diseases and increase mortality. According to the flat feeding density of cushion material, the feeding density was 30 × 35 / m ~ 2 before 6 weeks old and 12 ~ 15 / m ~ 2 before 18 weeks of age.

8. Grouping: the purpose of grouping is to make the development of chicks consistent and improve the survival rate. It is generally divided into groups at the right time according to their size and strength. For weak chicks, the nutrition level of feed should be improved and feeding management should be strengthened.

9. Hygiene: the nursery room should be cleaned frequently and the bedding should be changed in time. Feed trough, drinking fountain and nursery are cleaned and disinfected once a week, and drinking fountains are cleaned once a day. In and out of the nursery, change clothes and shoes, and set up a disinfection pool at the door for prevention and disinfection.
