瘦肉型北京鸭与樱桃谷北京鸭在武汉地区的产肉性能比较研究

     

摘要

以瘦肉型北京鸭与樱桃谷北京鸭为研究对象,在武汉地区相同饲养条件下饲养至6周龄,记录每周龄体重、饲料消耗,并于42日龄进行屠宰,测定各组屠宰性状指标并进行比较分析.结果表明,樱桃谷北京鸭早期生长速度稍高于瘦肉型北京鸭,但前5周两组间差异不显著(P>0.05),第六周时两组之间差异显著(P<0.05).瘦肉型北京鸭在料肉比、成活率、经济效益方面均优于对照组樱桃谷北京鸭.瘦肉型北京鸭的屠体重、屠宰率、半净膛重、半净膛率、全净膛重、全净膛率、胸肌率显著低于樱桃谷北京鸭(P<0.05),但腿肌率显著高于樱桃谷北京鸭(P<0.05),腹脂率低于樱桃谷北京鸭,但差异不显著(P>0.05).瘦肉型北京鸭与樱桃谷北京鸭相比具有其突出的优良特性.瘦肉型北京鸭和樱桃谷北京鸭在武汉地区的产肉性能差异,为瘦肉型北京鸭在南方地区的进一步推广提供了参考依据.%To investigate the difference of meat performance between lean-type and cherry valley Pekin ducks in Wuhan region, the two kinds of ducks were fed to the age of 6 weeks under the same condition and then slaughtered to obtain the body weight per week, feed intake and slaughter traits. The results showed that the early growth rate of cherry valley Pekin duck was slightly higher than the lean-type Pekin duck, there was no significant difference in the first 5-weeks in the two groups (P>0.05), but there was significant difference in the sixth week(P<0.05). Compared with cherry valley Pekin ducks, the feed conversion, survival rate and profit of the lean-type Pekin ducks were higher, the carcass weight, dressing rate, hah0 eviscerated weight, half eviscerated rate, eviscerated weight, eviscerated rate and breast muscle rate were significantly lower (P<0.05), and the leg muscle rate was significantly higher (P<0.05). The abdominal fat rate of lean-type Pekin duck was lower than that of cherry valley Pekin duck, but there was no significant difference between the two groups (P>0.05). It indicated that the lean-type Pekin ducks had its prominent characteristics compared with cherry valley Pekin ducks. It could be used as a reference for the extension of lean-type Pekin ducks in the southern area.
