Chicken house construction
The broiler house is generally selected where there is convenient traffic, flat roads, adequate water sources, and no noise sources and sources of pollution. There are many types of henhouses, and open-family or greenhouse sheds are usually selected for family farming.
The open chicken house is 20-30 meters long, 6-9 meters wide and 4-5 meters high. It is made of brick. Leave 2 convection windows in each house and leave one door for every 2-3 rooms. In order to facilitate prevention and cleaning, the ground is made of cement.
The construction of greenhouses is similar to the construction of plastic greenhouses for vegetables. It is constructed with concrete rods and bamboo poles. The height of 2.5-3.5 meters, covered with a double plastic film, can be placed between the double plastic film straw crops to enhance the ability to prevent cold and heat. The winter chicken house is surrounded by a plastic film, which is closed in summer for ventilation.
In the rural areas, chickens are often raised on the ground or raised in the ground. The ground level raising is generally 70-100 cm above the ground, and a chicken bed made of wood or bamboo pieces is constructed. Other facilities required for raising black-boned chickens include food troughs and water supply facilities. Large-scale farms also require ventilation facilities, heating facilities, and light-supply facilities.
Commercial chicken breeding
The 8-9 week old black-bone chickens are commercial chickens, and the stocking density of commercial chickens is 10-12 per square meter under flat-raising conditions. Commercial chickens grow fast. The diet must have high energy, protein, vitamins, and minerals. When rations are used, local feed resources should be fully utilized, combined with natural stocking to reduce investment costs. In order to speed up the growth of commercial chickens, the feed supply should be sufficient to allow them to feed freely. The black-bone chickens generally use dry powder feeds and are used with 10%-20% of green feed. In the breeding process, keep a quiet environment, timely observation of the chickens' reflections, and prevention and control of pests and diseases. When the black bones weigh about 1 kg, they must be sold in time.
Chicken breeding
0-7 weeks old for the brooding period, brooding room before brooding to be completely disinfected, all around the walls, floors, etc., first use 30% of the coal tar saponification solution disinfection, and then use 10% lime milk brush white, and finally at the per square meter with Fore Ma Lin (containing 40% formaldehyde) 14 ml, add water 20 ml, heat and evaporate for fumigation, and seal for 1-2 days.
Choose strong and strong young chicks and weed out diseased and underdeveloped weak chicks. 24-36 hours after hatching, drinking with warm water is started. There are two 45-liter tower-type drinking fountains per 100 chicks. In the first few drinking water, 0.01 grams of potassium permanganate can be added. After long-distance transportation, 50 ml of glucose or sucrose are added to increase the energy of the chicks. After starting drinking, the chicks began to feed a small amount of millet, broken rice, etc. that had been soaked in boiling water. After 2-3 days, the chickens were fed with feed. When feeding, feed less frequently, feed 2-3 times on the first day, then feed 5-6 times on a daily basis, and gradually transition to 4 times a day after 6 weeks. The feeding time is relatively constant. While feeding compound feed, about 10% of green feed can be added to save cost.
The chicks are sensitive to temperature, and the indoor temperature during the early brooding season should be controlled at 22°C-24°C, near room temperature at 3 weeks of age, and the minimum room temperature should be kept at 18°C. The relative humidity in the brooding room is kept between 60% and 65%. Drying or over-wetting is not conducive to the growth of the chicks. The brooding room should be ventilated frequently to prevent harmful gases from accumulating indoors. Take care not to cause the indoor temperature to fluctuate drastically during ventilation. The 1-3 day old chicks were kept in the light for 23-24 hours, the light was kept for 16-19 hours at the age of 4-14 days, and the light was kept for 8-9 hours after the 15th day. When the sun is lacking, artificial light is supplied and the light intensity is controlled to have one 25-40 watt incandescent lamp per 15 m2. The artificial light is strong in the first week, and the artificial light is weak in the remaining weeks.
The breeding density of chicks differs depending on the size of the chicks and how they are reared. In the ground-raising period, 30 breeding animals per square metre were raised within 2 weeks of age, 25 breeding animals were raised per square metre at the age of 3-4 weeks, and 20 breeding animals were reared at 5-6 weeks of age per square metre. Chicks should be cut twice at 10 days and 12 weeks of age, respectively. In the whole process of raising, we should do a good job of daily epidemic prevention and timely injection of various vaccines.
Disease prevention and control
Every month, use 2% -3% of fire alkali water to spray and disinfect the outside environment of the chicken house once a week. Disinfect the chicken in the chicken house once a week with 100 toxin or peracetic acid. Timely prevention of infectious diseases such as Marek’s disease, Newcastle disease, infectious bronchitis, and infectious bursal disease. 1-21 days of age in the feed or drinking water by adding norfloxacin, ciprofloxacin and other drugs to prevent bacterial diseases; 15-70 days of age in the feed by adding maduramycin, Taichenjing other drugs to prevent coccidiosis.
Timely fattening
The black-bone chicken enters the fattening period from the age of 7 weeks. This period requires not only a long flesh, but also a part of fat stored in the body, so the metabolic energy is higher than the previous period, the crude protein may be slightly lower than the previous period. The following recipes can be referenced: corn 64.5%, soybean cake 23%, bran 4%, imported fish meal 3%, bone meal 2%, salt 0.4%, yeast powder 3%, trace elements 0.1%, multidimensional pigment 10 grams. The metabolic energy was 12.5 MJ/kg, crude protein 18.8%, calcium 1.02%, and phosphorus 0.5%. Put the feed in the bucket or in the trough for free feeding and feed 3-4 times a day. Generally after 8-10 weeks of fattening, the flesh can be slaughtered when it weighs about 1 kg.
Layer Management
The black-bone chicken is generally at the age of 21-72 weeks for laying, and laying hens are raised on the ground for raising 5-6 eggs per square meter. Laying hens need more protein and calcium, the crude protein content is kept at 15%-17%, and the calcium content should be 3%-3.5%. During the production of eggs to maintain adequate light, light time to maintain about 16 hours, lack of light to artificial fill light. At the end of summer and early autumn, attention should be paid to the prevention and treatment of chicken diseases, and moulting of laying hens should be done in advance so as to prevent the occurrence of brooding and so on and increase the egg production rate.
Taihe Wuji
Taihe Wuji’s plumage is white and flawless, with a petite body, a compact body, and a gorgeous appearance. It enjoys a reputation both at home and abroad, and it is famous for medicinal purposes, nourishing and viewing. Taihe Wuji has stable genetic quality and pure quality. It is a rare rare bird in the world and a precious species resource in China. It was once a royal treasure of ancient royal families and it is now listed as an international standard variety. Taihe Wuji has the characteristics of small size, agility, strong foraging ability, and good adaptability.
Adult chickens are more adaptable to the environment and have fewer illnesses. However, young chicks have small bodies, weak physiques, and poor stress resistance. In the past, people generally thought that they were susceptible to disease, easy to die, and difficult to raise. However, after years of breeding research and raising the technical level of feeding and management, the brooding rate, the breeding rate, and the survival rate of breeders have all reached about 95%. Taihe black-bone chicken is very resistant to heat, but it is afraid of cold.
Taihe black-and-white chickens are very timid and can cause frightened chickens, affecting growth and egg production. Therefore, a more peaceful breeding environment should be created; Taihe black-breeding chickens are extremely mild and unfriendly, but they are best divided into male and female. The size of the group feeding, so that the growth and development of chickens uniform, tidy; Taihe Wuji good walk, but the poor ability to fly, easy management, generally using the ground level or online flat raising is appropriate.
Corn, rice, wheat, bran, green feed can be fed, but it should pay attention to the full price of feed, which is conducive to the growth of chickens and reproductive performance.
Taihe Wuji has a small body size. Adult males weigh 1.3-1.5 kilograms and adult hens weigh 1-1.25 kilograms. The rooster has a day of age of 150-160 days. The hens were born 170-180 days old. The annual production of eggs is about 100 eggs weighing about 40 grams, eggshell pale white, egg-shaped small and normal, egg-shaped index 74 or so. The hens are strong in their nests. In natural circumstances, they usually lay 10-12 eggs once per nest, and they nest for more than 15 days each time. The hatching period of eggs is 21 days.
