Abstract：The study was aimed to investigate the characteristics of Hyperpigmentation of the Visceral Peritoneum(HVP)in nine yellow-feather broilers.In this study,we analyzed the relationship between HVP and body weight(BW),Shank circumference(SC),and sex in nine 21-day-old yellow-feathered broiler lines(n=6223).The results showed that there were significant differences in HVP traits among different strains in different population genetic backgrounds(P<0.05).Notably local chicken exhibited a higher proportion of peritoneal black level 3 compared to specialized breeding lines.Under the same population genetic background,eight strains showed highly significant differences(P<0.01)in HVP,body weight,and Shank circumference,with lower BW and SC in the peritoneal black grade 3.Additionally,when males and females were analyzed separately,the HVP level was higher in the female chickens(P<0.01).The findings from our experiment suggested that selective breeding for lower HVP levels should prioritize local chicken breeds and hen groups,which provide a basis for future yellow-feathered broiler breeding and production.
