欧洲肉鸽Ⅱ系与欧洲肉鸽Ⅲ系杂交乳鸽生长、屠宰及肉品质性能分析OA北大核心CSTPCD
Growth,slaughter,and meat quality performance analysis of European meat pigeon Ⅱ line and European meat pigeon Ⅲ line crossbreeding
试验旨在探究欧洲肉鸽Ⅱ系与欧洲肉鸽Ⅲ系(OⅡ×OⅢ)杂交乳鸽在生长、屠宰及肉品质性能上的表现.试验选取40只0d的OⅡ ×OⅢ杂交乳鸽进行体重、体尺、屠宰性能及肉品质测定(公、母各半),并进行相关性分析.试验期28 d.结果显示,28 d杂交乳鸽群体均一性相对较好,除体重变异系数较大为9.93%外,体斜长、龙骨长、胫围、胫长、胸宽、胸深的变异系数均在7%以下.杂交乳鸽公鸽的腿肌重和腿肌率显著高于母鸽(P<0.05).杂交乳鸽体重与体斜长、胫围、胫长、屠体重等8项指标均达到了显著或极显著正相关水平(P<0.05或P<0.01).28 d杂交公、母鸽肉品质指标差异不显著,但公鸽的肉品质较优.研究表明,28 d杂交乳鸽的生长、屠宰及肉品质性能方面虽未完全超越亲本,但其群体的均一性和产肉性能良好,可为优质肉鸽的育种、生产提供一些参考.
The purpose of the experiment was to investigate the performance of the European meat pigeon Ⅱ line and the European meat pigeon line m(OⅡ ×O Ⅲ)in terms of growth,slaughter,and meat quality performance.In the experiment,forty 0-day-old O Ⅱ × O Ⅲ hybrid pigeons were selected to determine body weight,body size,slaughter performance,and meat quality(half in male and female),and correlation analysis was carried out.The experimental period was 28 days.The results showed that the population homogeneity of 28-day hybrid pigeons was relatively good.The coefficients of variation of body length,keel length,tibia circumference,tibia length,chest width,and chest depth were all below 7%except for body weight,which was 9.93%.The leg muscle weight and leg muscle rate of the male hybrid pigeons were significantly higher than those of female pigeons(P<0.05).The weight of the hybrid pigeons reached a significant or extremely significant positive correlation level with eight indexes,including body length,shin circumference,shin length,and slaughter weight(P<0.05 or P<0.01).There was no significant difference in meat quality between male and female pigeons at 28 days,but the meat quality of male pigeons was better.The results show that although the 28 day-hybrid pigeon does not completely surpass the parent in terms of growth,slaughter,and meat quality performance,its group uniformity and meat production performance are good,which can provide some references for the breeding and production of high-quality meat pigeons.
