Wuji is a famous local breed in China. It has delicious meat and rich nutrition. The content of amino acids and trace elements required by the human body is higher than the current domestic chicken. However, due to the single species of black-bone chickens, the viability and disease resistance are poor, and the survival rate is not high, resulting in difficulties in rearing. Therefore, farmers who raise broilers should focus on the following four points. First, health and epidemic prevention. The inside and outside of the house should be sterilized with 20% fire alkali water, and the walls should be painted white with 10% lime water. Padded grass should be ground-changing. Food troughs, drinking fountains, etc. should be washed every day. Every two weeks, use 1-2% caustic soda solution to disinfect once. Sweep out the faeces and bedding away from the burial. Second, drug control. During the first two weeks after chicks were hatched, four-fourths of a million doses of furazolidone or 4,000 units of chloramphenicol were administered daily to control paratyphoid fever and white peony. After 15 days of age, one ten-thousandth of furazolidone is fed daily or two-and-a-half-fold feeds of sulfamethazine are fed. Then stop for 1-2 days before feeding. After 45 days of age, it is necessary to control aphids. In addition, 8 days of age, 25 days of age, and 66 days of age were inoculated with chicken Newtown vaccine. Third, careful feeding. The survival rate of black-bucked chickens, the speed of fattening and the quality of management are very important. Diseased chickens should be kept in isolation. We found that chickens with uneven body quality and uneven quality were bred in groups. The temperature of the house should be maintained at 30-32°C during the chickling period. Afterwards, the temperature of the young chicks can be reduced by 1-2°C per week, and finally kept at about 20°C. The nighttime room temperature should be 2°C higher than the daytime. . Fourth, feed formulation. According to the requirements of chickens for protein in different growth periods, the total price of feed is provided: corn 50%, sorghum 10%, fishmeal 12%, bean cake 8%, meat powder 8%, wheat bran 5%, leaf powder 2%, ore Material phosphorus and calcium 1.5%, amount of growth hormone. In order to speed up fattening, it is usually fed 3 times a day and night with long-term light. In this way, the 90-day-old black-bone chicken can reach the sales standard.
