| Yellow-feathered broiler chickens play an important role in the development of chicken industry even the whole livestock and poultry industry in China. Nitrogen-corrected metabolizable energy requirement parameters of rapidly, mediumly and slowly growing yellow-feathered broiler chickens were reviewed. Combined with many collecting data of studies on energy requirements of yellow-feathered broiler chicken. Researches on crude protein, lysine, methionine, calcium, non-phytate phosphorus, sodium, chlorine, trace mineral elements and vitamin requirement of different types of yellow-feathered broiler chickens with different growth phases were reviewed. The suggested amino acid balance mode was presented. Most nutritional requirement parameters were compiled into agricultural industry standard Nutrient Requirements of Yellow-feathered Broiler Chickens （NY/T 3645-2020）, providing references for precise nutrition of yellow-feathered broiler chickens. Meanwhile, researches on meat quality regulation of yellow-feathered broiler chickens were summarized, mainly including the regulation of meat quality by nutrients such as vitamins and minerals, and non-nutritional additives like soy isoflavone. In terms of utilization of unconventional feed resources of yellow-feathered broiler chickens, studies on the application of unconventional energy feeds such as wheat and rice bran, unconventional protein feeds such as cottonseed meal, rapeseed meal and corn DDGS, and other unconventional feed resources such as mulberry leaf powder, moringa oleifera leaf and fermented leaves in yellow-feathered broiler chickens were also summarized, which provided references for the healthy and sustainable development of yellow-feathered broiler chicken industry. |
