[Objectives]This study was conducted to improve the production efficiency of dark-shank partridge-like plumage high-quality broilers and ensure animal welfare,so as to meet the development needs of China’s yellow-feather broiler industry.[Methods]Sichuan Animal Science Academy and Sichuan Dahen Poultry Breeding Co.,*** a joint breeding research *** team bred Dahen 799 broiler complete set line with local chicken breeds as the main material and improving production efficiency,stabilizing meat quality and flavor and achieving autosexing of chicks as the main breeding goals by modern poultry breeding technologies,after 10 years and 8 generations.[Results]The Dahen 799 broiler complete set line was approved by National Commission of Livestock and Poultry Genetic Resources in December *** 66-week-old egg production of the breed reached 189 *** the commercial generation,cocks and hens showed 10-week-old weights of 2668 and 2269 g,respectively;the feed conversion ratio was 2.26-2.35;the survivability was 96.7%-97.2%;and the average intramuscular fat contents of cocks and hens were in the range of 1.8%-2.1%,and the inosinic acid contents were in the range of 2.3-3.2 mg/*** production performance and meat flavor of Dahen 799 broilers were better than Dahen 699 broilers,Sichuan mountainous bone-black chickens and two other social *** with Sichuan mountainous bone-black chickens,the egg production at the age of 66 weeks increased by 47 eggs;the average weight of cocks and hens of the commercial generation at 10 weeks increased by 45.21%;and the autosexing rate of chicks of the commercial generation reached 99.3%.[Conclusions]Dahen 799 broilers have the advantages of good production performance,high feed conversion ratio and excellent meat flavor and the characteristic of autosexing which other breeds do not have,and can fully meet the industrial development needs of dark shanks and partridge-like plumage broilers.
