Green shell layer chicken: skin, hair, meat, internal organs are black, the production of egg shell is green, is a rare special poultry new products, has attracted the attention of domestic and foreign experts, because of its green shell egg contains a variety of Amino acids and trace elements that are beneficial to the human body are ideal health foods and are therefore popular with consumers. At present, there are few domestic animals and there is a large market demand. It is estimated that there will be large-scale breeding in the future. Chickens start eating 1, starting food: drinking water after 2-3 hours to eat. The starting material should have a certain particle size. The starting material should be crushed: 1 day old crushed material, 2 days old 2/3 corn flour +1/3 chick material, 3 days old 1/3 corn flour + 2/3 Chicken material was used and chick material was used after 4 days old. 2. Feeding techniques: (1) Feeding plate for chicks: The thickness of the feed in the pan must not exceed 1 cm. The litter and feces in the pan should be removed before each addition. Feed each morning and afternoon to ensure that there is sufficient feed at night. (2) Automatic feeder: control the feeder, only allow the chicken to eat the material in the feeder every day, and no material in the feeder can be left in the feeder. This is especially important in high temperature and high humidity areas. The lower edge of the feeder should be level with the chicken. Feed can only be added to 1/4 of the height of the feeder to avoid feed wastage. To increase the intake of chickens, increase the number of feeds within a fixed period of time. Decline in feed consumption may be the cause of the disease or poor feed quality. Health care 1, brooding brooding houses and utensils before brooding must be thoroughly cleaned and washed so that there is no residual dirt, and then strictly comprehensive disinfection procedures. 2, drinking water should be clean, moldy feed is prohibited, feed vitamins. 3, chickens should be kept in isolation from other chickens, utensils to be dedicated, especially early brooding to do a good job of prevention and treatment of intestinal bacterial infections. 0.04% Dietrich or broad-spectrum antibiotics can be added to the feed. After 15 days of age, the chicks should do a good job of prevention and treatment of coccidiosis. 4, the amount of medication must be accurate, pay attention to the course of treatment, the drug must be added to the feed mix, ensure control effectiveness and prevent drug poisoning. You cannot add furazolid in feed and drinking water. All hens reared on broilers in open chicken houses should be crippled. Cutting off the best at 7-10 days or 10-14 weeks of age. However, if fleas occur, either at the time of brooding or rearing, there will be no side effects. The rooster usually does not need to be broken. If necessary, just touch the tip of the roach on the hot blade. Feeding Density The ideal stocking density depends on the management conditions, climate, and type of house. The general recommendations are: 15 to 20 per square meter for 1-4 weeks of age and 8-10 per square meter for 7-20 weeks of age. 1. Cage raising: (1) Preparation for raising chicks: 1 Open the cage door before the chick arrives. 2 Adjust the nipple drinker to the correct height. 3 Check the nipple drinker to prevent it from malfunctioning. 4 Prepare and adjust the cockpit floor as recommended by the manufacturer. 5 Adjust the cage to facilitate food intake. 6 Check the ventilation, heating, light, temperature indicator and alarm system so that they are in normal working condition. 7 The feed in the feed tank should be added to the appropriate height, typically 1/3 of the height of the feed tank (after the chicks drink 2 to 3 hours before feeding). (2) How to place chicks: 1 The house is heated and heated. When the chicks arrive, the temperature in the house should be controlled at 28°C or more. After the chicks entered the cage, they rose to 32°C. 2 If the direct method is used, the temperature at the back of the chicken should be 32°C-33°C. 3 When the chick arrives, place the box containing the chicks on the aisle and open the lid. 4 Put the chicks into the cage as soon as possible to prevent overheating inside the chicks. 5 Check all the cages again to ensure that the chicks are able to feed and drink adequately and that the chicks cannot escape the cage. 6 After the long-distance transport of the 6 chicks, 5% sugar should be added to the drinking water on the 1-2 days old. 2. Peace raising: (1) Preparation for chicks before arrival: 1 Turn on all lights and adjust dimmer to 100%. 2 Adjust the temperature at the chicken's back height in the brooding chamber to 32°C to 33°C. 3 Distribute chick waterer (at least one for every 100) and put it in warm water (18°C). Add 5% sugar or 5% dextrose water in drinking water on the first day and add more Vitamins, antibiotics, electrolytes, etc. 4 If a plastic feeding tray is used, it should be dispersed and placed before feeding. The feed thickness is about 1 cm. If there is no suitable feed tray, the cardboard box can be cut and used as a feed tray. The separators and liners in the box are removed. The cartons are cut into 4 cm high, and 1 cm thick feed is added; for every 100 chicks Need to raise the area of ​​0.2 square meters. Be sure to have enough suitable drinkers. (2) After the chick arrives: 1 Remove the chicken box as soon as possible, disperse it in the house, and open the lid. 2 In the brooding room, evenly place the waterer and trough. The chick waterer must be stable to prevent overflow. Then, from the far end of the house, carefully place the chicks around the waterer and the feed pan. 3 Check the temperature again. The distribution and behavior of the chicks is a sign of whether the temperature is appropriate or not. If the chicks are distributed evenly and freely, the temperature is normal; if the chicks squash, it means that the temperature is too low and the temperature needs to be raised; if the chicks stand with their wings open and breathe, indicating that the temperature is too high, the temperature must be gradually reduced. 4 Keep the chicks individually under another brooder (at least 2 brooders). If using a hothouse brood, you can place them in warmer enclosures. The appropriate temperature required for males in the first 2-3 days of age is 1°C-3°C higher than that of the female chicks. By the end of the second weekend, males should be mixed with their mothers and chicks to reduce excessive stress caused by the young chicks being put into the mother-and-child group too late. 5 During the first two days, the chicks can be fed some ground corn (or barley) at a rate of about 7 kilograms per 1,000 pounds. 6 For use with automatic drinkers, every 100 chicks are given a drinker for the first 10–14 days of age and can be used for the first drinking immunization. Drinking fountains must be cleaned daily and fresh drinking water added. Daily management 1. Items observed on a daily basis: health status, distribution of birds, temperature, ventilation, feed and drinking water, lighting, egg production, feed consumption, fecal status and mortality. Timely elimination of stunted chickens and chickens that cannot feed on drinking water, collecting dead chickens and burning them or removing them. If you suspect that the disease is a chicken disease, you should immediately inform the veterinary technical service personnel to send the diseased chicken to the laboratory for inspection. 2. Equipment required for ground management: (1) Drinking tray for chicks: At the age of 5 to 10 days, one for each 100 chicks needs a drinking water tray with a capacity of 4 liters. (2) Drinking fountain: A round drinking fountain with a diameter of 33 cm can be used by 100 chickens. If it is a nipple drinker, it can be dispensed every 4-6. (3) Chicken trays, one for every 60 chickens; 0.24-0.25 square meter base area and 4 cm high shear trays for 100 chicks. (4) Feeder (per 100 chickens): 3 to 10 weeks old: 2.5 to 3.5 meters long chute or 2 round barrels 40 centimeters in diameter; 11 to 20 weeks old: 4.5 meters long Three troughs or drums with a diameter of 40 cm; egg laying period: 6-meter troughs or 4 drums with a diameter of 40 cm. (5) Nests: Individual nests, 30 cm wide, 32 cm long, and 45 cm high; each group of 4 hens has a nest box, and each 20-25 hens need an area of ​​1 square meter. (6) brightness regulator: to adjust the light intensity, light intensity should not be strong or weak. (7) Grid: The chicken house is divided into approximately 100 square meters per area. 3, keep the appliance clean: (1) automatic drinker: always keep drinking water clean, summer need to be cleaned daily. Keep the water level as high as possible during the first few days. When the chicks are adapted to the drinking fountain, the water level can be lowered to prevent overflow. Adjust the height of the waterer at all times and keep it at the same height as the back of the chick. (2) Nests: The wet litter must be removed in a timely manner, paying particular attention to the area around the drinker. It is necessary to keep the “dumb type†nest boxes clean and change their litters frequently. When using “sloped†nest boxes, keep the egg trays and egg collection belts clean.
