Quality Yellow Broiler Breeding and Management Points
Local yellow feather chickens have low fertility, slow growth, low feed returns and poor aquaculture efficiency. Therefore, some scientific research, teaching units, and poultry breeding companies have purified some local yellow feather chickens and matched them with the imported fast-growing broiler chicken breeds. A number of high-quality yellow feather broiler breeds have been selected and produced. In particular, the growth rate has increased, and the appearance of the physical appearance has become uniform. Such as Huiyang chicken, Qingyuan Ma chicken, Shiqi hybrid chicken, Beijing oil chicken, 882 yellow chicken, Jiangcun yellow chicken, etc., these chicken species not only retains the original local yellow feather chicken meat flavor, but also have a higher production of meat Performance, increase production efficiency. As high-quality yellow feather broilers grow fast, have high feed rewards, are tender and delicious, and have the characteristics of local yellow feathered chicken “three yellows†(feather yellow, yellow, yellow, yellow), it has become an important issue in the development of broiler production. direction. However, compared with fast breed broiler breeders, high quality yellow feather broilers have slow growth and long cycle times. Starting from this basic difference, there are the following characteristics in the production and management of high quality yellow feather broilers. 1. High-quality yellow broiler chickens can't deliberately pursue the growth rate, but should pay special attention to meat quality and appearance traits. They should be listed as crown-red, red-brown, yellow-brown (maw), yellowish-brown, and short and yellow. Different from the fast-growing large-scale broiler chickens, the blind pursuit of growth speed, the faster the faster the better the characteristics. 2. The market price of high quality yellow feather broiler cocks and hens varies greatly. The hen price is about three times the price of the cock. The hens are mostly supplied to Hong Kong, Macao and high-end restaurants in the form of live chickens, and the cocks mostly enter ordinary citizens' dining tables. 3. Feeding methods. High-quality broilers have strong adaptability, which can be used for raising litter, raising the cage (grid), and can also be used for raising cages. High-quality yellow feather broilers have slow growth rate and low body weight, so the phenomenon of breast cysts does not occur basically. Cage culture can be adopted, especially in the later finishing stage. Cage culture can significantly improve the fattening effect. In some large yellow broiler chicken farms in Guangdong, fire bred brooding is adopted during the 0-6 weeks brooding period, bamboo crickets or metal cages are bred on the web for 7-11 weeks, and the animals are put on the cage for 12-15 weeks. 4. Immunity content. Since high-quality yellow broiler chickens have a longer feeding cycle than fast-grown broilers, some immunization should be added. For example, Marek's disease, because the disease mostly occurs after 2 months of age, so high-quality yellow feather broilers must be vaccinated with Marek vaccine immediately after hatching. Other immunization programs should also be considered based on the characteristics of the region's disease. 5. Feeding stage and feeding standards. The high-quality yellow feather broilers bred and bred were mostly medium-sized chickens. Their early growth rate was significantly higher than that of local yellow feather chickens. The 10-week-old body weight reached 1.65 kg. After 10 weeks of age, the growth slowed down. Therefore, according to the growth characteristics of high quality yellow feather broilers, the feeding period is generally divided into three stages, namely brooding period (0 to 6 weeks old), growing period (7 to 11 weeks) and fattening period (12 weeks or more). Large yellow broiler chickens have a slower growth and a longer feeding period than large fast-growing broilers. Therefore, the requirement for dietary nutrient content is lower than that for fast-large broilers. However, due to the large differences in the growth rate of different high-quality yellow feather broiler breeders, the feeding standards cannot be unified. Breeding companies are developing through feeding trials. It is not appropriate to follow the feeding standards of fast-growing broilers blindly because these standards are higher than the growth needs of high-quality yellow feather broilers and affect feed remuneration and chicken quality.
