【摘要】：为提高乌骨鸡的肉用性能和营养价值,满足市场对乌鸡品质与数量的需求,培育乌肤均一的乌鸡新品系。本试验对正培育的A系、C系、D系、E系、CS系五个新品系乌鸡的初生重、宰前活重、全净膛重+头脚重,乌度(包括胸肤、腿肤、翅肤、背肤、胸肌、腿肌六个部位)仪器测量色差值进行单因素方差分析和相关性分析。结果表明,E系初生重显著高于其他各个品系(P0.05),A系、D系宰前活重和全净膛重+头脚重显著高于其他各系(P0.05);NR型颜色色差仪测定不同部位乌度结果显示:各部位乌度都较好是CS系,其次是C系、D系,这两个新品系甚至在腿肤、翅肤的乌度比W系(市场上推广好的品系)表现好。而A系、E系与W系相比差异不显著(P0.05)。六个品系全净膛重+头重与不同部位乌度的相关性分析,在乌鸡乌肤选育过程中,腿肤,翅肤和胸肤可以作为选育的主要指标。综合可知,D系在屠宰性能和乌肤性状表现上均良好,基本符合生产要求和市场需求,其他品系的屠宰性能或肤色有待于提高。各个品系背部的乌色均匀度也有待提高。
[Abstract]:In order to improve the meat performance and nutritional value of silky chicken and meet the demand of the market for the quality and quantity of black chicken, a new black chicken strain with uniform skin was bred. In this experiment, the birth weight, premortem life weight, full bore weight, head and foot weight, black degree (including chest skin, leg skin, wing skin, back skin, pectoral muscle) of five new strains of silky chicken were studied, including chest skin, leg skin, wing skin, back skin and pectoral muscle. The color-aberration was measured by single factor analysis of variance (ANOVA) and correlation analysis. The results showed that the birth weight of line E was significantly higher than that of other lines (P0.05). The weight of head and foot of line A and D was significantly higher than that of other lines (P0.05). The second is C line D line, these two new lines even in leg skin, wing skin than W line (well promoted on the market). There was no significant difference between A line E line and W line (P0.05). The correlation analysis between the head weight of the six lines and different parts of the black chicken showed that the leg skin, wing skin and chest skin could be used as the main indexes in the selection process of black chicken black skin. The results showed that the slaughter performance and black skin traits of line D were good, which basically met the requirements of production and market. The slaughtering performance or skin color of other lines needed to be improved. The color uniformity on the back of each strain also needs to be improved.
