Royal chicken, also known as noble chicken, originated in Britain, France, the Netherlands and other European countries, is a famous European specialty. The lady chicken is a combination of ornamental, gourmet and nourishing meat. At present, the broiler chicken has become a representative of new varieties of special poultry. The supply of seedlings in the domestic market is in short supply. The breeding of broiler chickens is rising quietly in the country and there is a very attractive prospect for the development of broiler chicken breeding. The following describes the technical aspects of female chicken farming for reference.
1, site and equipment. It is easier to breed lady chickens than other special poultry and poultry. The premises are well-located north to south, with sufficient hydropower, quiet environment, convenient transportation, and dry leeward conditions. Large-scale farm buildings can be referenced to chicken farms. And supporting hatching machine, hatching machine. Domestic or professional households can make use of the idle housing to adapt to local conditions, strictly introduced after disinfection. The condition of the available brick and tile structure of the plant, but also available bamboo shed or plastic shed, each 28 meters long, 6 meters wide, 3 meters high, 3-4 net room as a playground. Each can raise 500-600 chickens and 800-1000 chickens. The brooding is done on a flat ground. The brooding room can be divided into small rooms of 18 square meters and 200-300 brooders per room.
2. Nutrition needs to work with feed. In different stages of growth, ladies also need different levels of nutrition. Its nutritional standards are currently lacking detailed information. Chickens can be fed with pellet feed and chicks can be fed with chicks within one month of age. In order to increase the growth rate of broiler chicken brooding, it is recommended to add 4% imported fishmeal, 6% feed yeast or feather meal, appropriate amount of cod liver oil, and B miscellaneous water to the chicken feed (40 kg) per package. Chickens aged from 2 months to 5 months were fed either with medium or large chickens. The laying hens can choose chicken eggs or chickens for full price feeds. In order to obtain high yields and improve the quality of the breeding eggs, it is recommended that 20% of the material is used in chicken eggs or chicken eggs in each package (40 kg). Imported fish meal, 5% feed yeast.
3, hatching and brooding. Ladies produce up to 150-180 eggs per year. Each egg weighs about 40 grams. The shells are white, and the average longitudinal and transverse diameters are 5.5 cm and 4.0 cm, respectively. According to the statistics of Shanghai Jianong Agriculture and Animal Husbandry Technology Service Co., Ltd., the fertilization rate of female eggs from March to August each year is approximately 86% to 90%, and the hatching rate of fertilized eggs is approximately 90%. There are two kinds of methods for hatching female chickens: farmer-raised female chickens, which can be used as hatchers for hatching eggs, and 18-20 eggs can be hatched at a time. Large-scale breeding can be hatched by using an electric hatchery. The hatching method can refer to the chicken hatching method. . Because of its strong resistance to stress, the broiler is easy to brood. The brooding survival rate is as high as 95% at the age of 30 days. The average weight of hatchlings when hatched is about 30 grams, about 100 grams at 15 days, and 300 at 30 days. Grams. Female chickens are hardy, and the suitable temperature is 32°C at l-2days of age. Afterwards, it can be reduced by 0.5°C per day until it is maintained at 22°C to desuperheat after 21 days of age. The relative humidity in the week before brooding is 60%-65%, and after one week, it can be reduced to 50%-60%. Within one week of age, it can raise more than 100 eggs per square meter, and gradually decrease thereafter. After hatching, the chicks should be provided with clean drinking water and full-day feed throughout the day. The feed requires fresh and full-priced nutrition.
4. Chickens, chickens and feeding management. During the period of 2-5 months, it is called the chicken stage. As a commercial chicken, it can be sold in 90-120 days. As a breeding breeder, 120-180 days old chicken is called the reserve chicken. During the period of 2-4 months of age, commercial lady chickens should be fed on a full day basis. Reserve chickens should be limited to feeding during the period of 4-5 months, each about 100 grams per day. Under the conditions of flat raising, 8-10 can be raised per square meter. When raised to 6 months of age, it can be used as a chicken feeding tube. The second selection of the breeder was carried out at the first half of the month before delivery. When the weight of the rooster was 1.5 kg and the hen was 1.25 kg, the male-female ratio was chosen as 1:3-4. Breeding chickens feed on laying hens, feeding high protein diets at the peak of the production, the crude protein reaches 18%, the laying hens consume about 100-125 grams per day, and can raise 4-5 per square meter. Only, light 15-16 hours a day, light intensity of 40 watts per 15 square meters a trip, 2 meters off the ground. Kinds of hens and sports grounds are equipped with sand, allowing chickens to freely eat sand and sand. In order to increase the fertilization rate of the eggs, vitamin E can be added to the feed and 10 mg per kg feed.
5, the prevention of chicken disease. European noble chicken is a new breed of special poultry that is very resistant to disease. It is generally less contagious, but it is also transmitted to chickens and causes epidemics. Therefore, local farmers should be targeted for vaccination according to local conditions. The following describes the routine control methods: 1 day old (within 24 hours of shelling) in the lateral thigh lateral Marek's disease vaccine, 5 days of age with chicken Newcastle disease II vaccine nose or eyes; 18-21 days of age Beverage service contagious Poison attenuated vaccine; 25-30 days old diarrhea chicken Newcastle disease II vaccine. When the rearing chickens were 50 days old and 135 days old, they were injected with 0.5 ml of chicken Newcastle disease vaccine respectively. At 135 days of age, they were injected with inactivated oil adjuvant vaccine. The Newcastle Disease I vaccine was administered intramuscularly to the breeder chicken each year during the off-breeding period. After 40 weeks of age, the inactivated vaccine was intramuscularly injected with cystic disease. When the chicks are l-7 days old, 0.01% norfloxacin is used, 0.05%-0. l% chloramphenicol powder or 0.02% -0.04% furazolidone to prevent bacillus bacillus disease. In the 3-25 years of age, compound ammonia, ball net, globule powder and trilobular coccidia should be used alternately to prevent coccidiosis. In normal times, chickens are affected by stress factors, such as fast supplements-14 or erythromycin thiocyanate.
