3个鸽品系雏鸽体重、体尺和屠宰性能测定与比较
Measurement and comparison of body weight,body size and slaughter performance of three lines of squabs
摘要
Abstract
This experiment was aimed to explore the differences in body weight,body size,and slaughter performance among three pigeon lines of different genders.Measurements of related indices were conducted on three pigeon lines,namely D,M,and T,at the age of 28 days,with each line consisting of 60 individuals(30 males and 30 females).The results showed that the D line exhibited significantly higher values in live weight,dressed weight,tibia length,tibia circumference,and body oblique length compared with those of the M line(P＜0.05).Both line and gender had a significant impact on body size and slaughter performance.However,there were no significant differences in the slaughter rate,evisceration rate,and breast muscle rate among different lines and genders(P＞0.05).Moreover,the slaughter rate and evisceration rate were both above 80%and 60%,respectively,meeting the requirements for good meat production performance.The cor-relation analysis between the body weight,body size,and slaughter performance of the birds indicated a high correlation between body size traits,such as chest depth,chest width,tibia circumference,and slaughter performance indicators,including live weight,evisceration weight,and breast muscle weight.In summary,the body size and slaughter performance values of the male pigeons were higher than those of the female ones.The three lines all exhibited favorable meat production performance.Furthermore,there was a strong correlation between the body size and the slaughter performance of the pigeons,suggesting that chest width and other body size indicators could be used to predict the slaughter performance of pigeons and accelerate the breeding progress of the birds.关键词
