Special poultry show - green shell black chicken and its breeding techniques
Green shell black chicken, characterized by five black - green, hair, skin, flesh, bone, viscera black, eggshell green. It is a unique special poultry rookie. It is very rare at home and abroad and has attracted widespread attention and attention from people in the industry. The green eggs produced by this chicken are not the effects of pigment additives. They are pure natural, rich in protein, and yellow in egg yolk. They contain a lot of lecithin, vitamins and trace elements. The meat is delicate and tender, and its nutritional value is much higher than ordinary chicken. Green shell black chicken temperament, hi group living, disease resistance, adaptability, can be farmed everywhere. It eats grains and eats green fodder. It grows fast and produces more eggs. Hens produce 160 to 190 eggs each year, and the hatching rate and survival rate can reach 90%. Shell out for 80 days up to 1 kg or so can be listed. Adult cocks 1.5 to 2 kg and hen 1.2 to 1.5 kg. Now the green shell black chicken breeding technology is introduced as follows: First, the chicken house construction chicken house built in the ventilation sunny place, before and after every 3 meters to open a 70120 cm light ventilation window, indoor can be placed on one side of the habitat, drinking water The feeders and chutes are distributed at equal distances. At the same time, a small door with a height of 160 cm and a width of 70 cm is opened on the side of the sunny side, and a sports ground with sand is 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. On the 1st to 18th days after hatching, the egg surface temperature should be 37.8°C on cold days and 37.5°C on 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 once per hour, angle 90. 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%, metabolism Can 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. The indoor 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 of chickens is generally composed of rice, corn, bran, bean cake, fish meal, bone meal and the like. 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 feeding every day and night feeding 7 to 6 times; 16 to 30 Only 5 times during the day. The chick’s drinking water must be supplied all day long and should be clean. The first week of light is 23 hours a day and the second week is 15 hours a day. The light intensity is calculated as 3 watts per square meter, 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 use, it is divided into two types of dietary chickens and reserved breeder chickens at this stage. It is advisable that the dietary chickens feed the full-price broiler chicken feed, and they can freely feed and feed the green fodder at their discretion. 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 morning and evening low artificial light. 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 and feed rewards decrease. 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 breeder chickens: First, rational grouping, elimination of stunted males and females, 150 to 200 per group is appropriate, male and female ratio is 1:4; second is proper stocking density, generally 6 to 8 M2; third is to ensure light, using 8 hours of light a day; four is to strengthen their movements to enhance physical fitness; 5 is a timely repellent, 8 to 10 weeks drive aphids once, in the production of pre-manufacturers locusts, 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 advisable to use 100 to 150 breeders per breeder. Feed the full price of breeder's pellets at the beginning of the first half of the month, feed 60 to 70 grams per day, feed 3 to 4 times a day, and provide clean drinking water for the whole day. , And feed green material 2 to 3 times. From the age of 20 weeks, gradually increase the light, require 16 hours of light every day, every 40m2 can install a 40-watt light bulb, 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. The hatchery chicks should be injected with Marek's vaccine, 7-10 days old chicken Newcastle disease II seedlings should be given nasal drops or drinking water, and chickenpox vaccine should be given at the same time. Care should be taken to prevent coccidiosis before and after 20 days of age. Breeders should do preventive work on inactivated vaccines such as Newcastle disease, bursa of Fabricius, and infectious bronchitis, and they can formulate immunization programs in combination with local chicken immunization programs.
