What kinds of broilers are raised at present?

Variety is the product of artificial selection. They have the same origin, similar physical form and production performance, the same adaptability, stable heredity, certain economic value, certain structure and sufficient quantity. Broiler breed is a kind of chicken breed which specially meets the human demand for chicken protein, and has the characteristics of fast growth and good meat production performance. At present, there are mainly two kinds of broiler breeds raised in China. One kind is fast and large white feather broilers (generally called broilers), and the other kind is yellow feather broilers (generally called yellow chickens, also called high-quality broilers). The main characteristics of fast large broilers are fast growth and high feed conversion efficiency. Under normal circumstances, the body weight can reach 2650g in 42 days, the feed conversion rate is 1.76, and the breast meat rate is 19.6%. The main differences between high-quality broilers and fast-growing broilers are slow growth, low feed conversion efficiency, strong adaptability, easy feeding and good chicken flavor and quality, so they are widely welcomed by consumers in China (especially in South China) and Southeast Asia.

In the modern production of commercial broilers, hybrid chickens cultivated by modern breeding theories and methods are widely used to cooperate with general strains. Paternal line and maternal line are two different varieties, and paternal line, paternal line and maternal line are different. From the paternal coat color, there are two kinds of white feathers, and the growth rate, feed conversion rate and economic benefits of white feathers are better than those of color broilers. White feather broilers account for an absolute majority in the broiler industry in the world today.

Modern white feather broilers are mostly Cornwall chickens with fast growth and good breast and leg meat development. The maternal line is mostly white rock chicken with high egg production and good meat performance. Commercial broilers produced by double cross have fast growth rate and high feed conversion rate. The weight of 7-week-old broilers can reach more than 2.0 kg, and the consumption per kg is 1.8 ~ 2.0 kg.

At present, there are dozens of poultry breeding companies in the world, of which the United States accounts for the vast majority. The following are some famous companies and their chicken breeds:

The above broiler breeds are all excellent broiler breeds in the world at present. Due to the need of foreign trade export, a small number of parents were introduced to China from the mid-1960s. Since 1980s, with the implementation of the policy of opening to the outside world and invigorating the domestic market, the number of imported chickens has been increasing, including not only parents' generation, but also grandparents' and great-grandfathers' generation, which has promoted the development of broiler industry in China.

As far as actual feeding is concerned, there are several kinds of broilers with good production performance in our region, such as Avian, Aiba Yijia (AA), Roman and Xingbro, which are raised in large quantities.
