Abstract：The experiment aimed to investigate the differences in growth performance,slaughter performance,and meat quality among the Fl generations of three hybrid combinations of European Meat Pigeon Line Ⅱ,European Meat Pigeon Line Ⅲ,White Carnoeau Pigeon,and Tarim Pigeon,in order to screen for the best meat-purpose combination.A total of 150 F1 generation healthy suckling squabs were selected,respectively from European Meat Pigeon Line Ⅱ ♂ × European Meat Pigeon Line Ⅲ ♀(group O2O3),European Meat Pigeon Line Ⅲ♂× White Carnoeau Pigeon♀(group OK),and Tarim Pigeon ♂ × White Carnoeau Pigeon♀(group TK).The test period was 28 days.The results showed that regarding body weight,groups O2O3 and OK were extremely higher than group TK(P＜0.01).In terms of body size indexes,the values for body slope length,keel length,shank length,and chest depth in group OK were higher than groups O2O3 and TK.Except for chest width,the other five indexes in the group TK were lower than those in the other groups.For slaughter performance,the slaughter rate of group O2O3 was significantly higher than that of group TK(P＜0.05),eviscerating percentage was extremely higher than that of group TK(P＜0.01).The slaughter rate and eviscerating percentage of group OK were extremely higher than those of group TK(P＜0.01).Regarding organ indexes,the bursa of Fabricius,lung,and glandular stomach indexes of group TK were significantly or extremely higher than those of group O2O3(P＜0.05 or P＜0.01),and the glandular stomach index was extremely higher than that of group OK(P＜0.0l).In meat quality,the pH value of breast muscle in group O2O3 was extremely lower than that in group TK(P＜0.01),and significantly lower than that in group OK(P＜0.05).The shear force of breast muscle was extremely higher than that of group TK(P＜0.01),and significantly higher than that of group OK(P＜0.05),while the water loss rate was extremely higher than that of groups OK and TK(P＜0.01).The shear force of leg muscle in group TK was extremely higher than that in groups O2O3 and OK(P＜0.01),and the water loss rate was significantly higher than that in group OK(P＜0.05).The study indicates that the F1 generation of European Meat Pigeon Line Ⅱ ♂ × European Meat Pigeon Line Ⅲ ♀ demonstrates the best overall performance in growth performance,slaughter performance,and meat quality,and is recommended as an excellent cross combination for meat pigeons.
