Green shell black chicken and its breeding techniques

1. The chicken house is built in a ventilated and sunny place, and a 70120 centimeters lighted ventilation window can be opened every 3 meters before and after, and the indoor can be placed on one side. The drinking fountains and troughs are distributed at equal distances.

In the house, at the same time, on the side of the sunny side, a small door with a height of 160 cm and a width of 70 cm was opened, and a sports ground with sand was set outside the door. Kinds of chicken coops also set up nest boxes, fine sand inside the box.

Second, artificial hatching eggs should be selected more than 40 grams each, in batches into the eggs should adopt constant temperature incubation, each batch of eggs require cross-interval placement, the big head up on the egg tray. Incubation 1-18 days

The egg surface temperature is 37.8°C in cold days and 37.5°C in hot days. On the 19th to 21st days, it is appropriate to use cold days at 37.2°C and hot days at 37°C. Relative humidity is 60% for days 1-18 and 70% for days 19-21. turn

The egg is carried once every hour, at an angle of 90 degrees. Normal hatching begins on the 20th day and the hatching is completed on the 21st day.

Third, feeding and management of green shell black chicken nutrition requirements: chicken feed 20% crude protein, metabolic energy 2850 kcal / kg; young chicken feed 15% crude protein, metabolic energy 2750 kcal / kg; breeder feed

Protein 17%, metabolic energy 2800 kcal/kg.

1. Feeding and Management of Chicks: From the shell to the 30th day of age, it is used as a chick. The temperature in one week is required to be 33°C, and then it is lowered by 2°C every week. The principle of heat preservation is appropriate to distribute the chicks evenly around the heat source. indoor

The relative humidity is controlled at 60~65% and the ground should be kept clean and dry. The brooding density ranged from 40 to 50 on the 1st to 10th day of age, 30 on the 11th to 20th day, and 20 on the 21st to 30th days. The feed for chickens is usually rice

, corn, bran, bean cake, fish meal, bone meal and other components. 1 to 3 days of age without quantitative free intake; 4 to 7 days of age feeding 8 times per day and night, each feeding should not exceed 15 minutes; 8 to 15 days of age every day and night

7 to 6 times; 16 to 30 days of age only fed 5 times during the day. The chick’s drinking water must be supplied all day long and should be clean. Illumination 23 hours per day in week 1, 15 hours per day in week 2, light intensity per square meter

It takes 3 watts to calculate and natural light can be used later.

2. Feeding and management of young chickens: After the chicks are raised to 30 days old, they will enter the young chicken rearing stage. According to the purpose of use at this stage is divided into two types of dietary chickens and back-breeding chickens, the best dietary chicken

Feed the full-priced broiler feed, free access to feed, and supplement green feed as appropriate. Change fresh water daily to ensure plenty of water. Breeding density 15~12/m2, temperature 15~20°C, relative humidity

50~55%, natural light during the day, supplemented by low and early artificial lighting. When they are raised to about 80 days of age, they will be sold on the market when they weigh between 0.9 and 1.2 kg. Otherwise, the growth rate slows down.

The material rewards are reduced.

The rearing breeders should adopt limited feeding methods to prevent premature and over-fertilization. Feedstock can be purchased and reserved for chicken feed, and ensure that drinking water is sufficient and clean. Management of reserved breeders: First, rational grouping,

Elimination of the stunting male and female chickens, each group is suitable for 150 to 200, the ratio of male and female chickens 1:4; the second is the appropriate breeding density, usually 6 to 8/m2; the third is to ensure light, using 8 hours per day Light

According to the law, the fourth is to strengthen its exercise to enhance physical fitness; Fifth, timely deworming, 8-10 weeks drive maggots once, in the production of pre-drive maggots, aphids and flukes once.

3. Breeding and management of breeder chickens: After 20 weeks of age, they enter the rearing stage of breeders. It is appropriate to breed 100 to 150 breeders per breeder. Feed the full price of breeder's pellets in the first half of the month, and feed 60~70 per day.

g, divided into 3 to 4 feedings, full-day supply of clean drinking water, and feeding greens 2 or 3 times. Gradually increase lighting from 20 weeks of age, require 16 hours of light per day, and install a 40 watt bulb every 15 m2.

The red light is better. The optimum temperature during the laying period is 18~25°C and the relative humidity is 50~55%.

Fourth, the disease prevention and control of green shell black chicken disease is less, but it should still take "early disease-free prevention, disease early treatment" measures. Injected Marek's vaccine for hatched chicks, Newcastle disease chickens 7 to 10 days old

Injecting nasal drops or drinking water, and inoculating chickenpox vaccine at the same time, care should be taken to prevent coccidiosis before and after 20 days of age. Breeders need to do preventive work on inactivated vaccines such as Newcastle disease, bursa of Fabricius and infectious bronchitis.

The immunization program can be formulated in conjunction with the local chicken immunization program.
