摘要/Abstract

摘要： 本研究选择笼养和放养条件下49周龄的卢氏绿壳蛋鸡各20只（公母各半），测定了其屠体性状。结果表明，饲养方式对卢氏绿壳蛋鸡的活重、屠宰率、半净膛率、全净膛率、胸肌率、腿肌率、腹脂率、翅重、心脏重、肝脏重、脾重、肠重、胃重和生殖器官重的影响均差异不显著（P>0.05）。饲养方式对公鸡的各项指标影响差异不显著（P>0.05），而对母鸡的头重、颈重、脚重影响很大（P<0.01）；相同饲养条件下公鸡的全净膛率、腹脂率、头重、脚重、颈重、翅重、心脏重和肠重极显著高于母鸡（P<0.01），对肝脏重、脾脏重和胃重的影响差异不显著（P>0.05）；笼养时公鸡的活重、腿肌率和生殖器官重显著高于母鸡（P<0.05），而对半净膛率和胸肌率的影响不显著（P>0.05）；放养时母鸡的生殖器官重极显著的高于母鸡（P<0.01）；不同饲养条件下，公鸡头重、颈重、肠重、生殖器官重与屠宰率相关性不显著（P>0.05）；母鸡脚重、翅重、肠重、脾脏重与屠宰率的相关性显著（P<0.05）。

Abstract: 20 Lushi green-shell-egg chickens reared in two different ways were tested in this research, which half were reared in cage and other half reared in free-range separately. Ten of these chickens’ carcass performance was measured after slaughtered randomly (5 emale and 5 female) when the chickens were reared at 49 weeks of age. The results indicated that there were no significant differences in live weight, slaughter rate, half carcass weight rate, eviscerated carcass weight rate, breast muscle rate, leg muscle rate, abdominal fat rate, wing weight, heart weight, liver weight, spleen weight, intestines weight, stomach weight and the weight of reproductive organs(P>0.05) between two rearing ways. There were no significant difference on all of cocks’ carcass performances in two rearing conditions (P>0.05), whereas there were extremely affection on hens' the head weight, the neck weight and the foot weight (P<0.01). At the same raising condition, the cocks’ eviscerated carcass weight rate, abdominal fat rate, head weight, foot weight, neck weight, wing weight, heart weight and intestines weight were higher than hens’(P<0.01), but there were no significant difference on the liver weight, spleen weight and stomach weight (P>0.05). The cocks’ live weight, leg muscle rate and the weight of reproductive organs were higher than hens’ (P<0.05), but not significance on half carcass weight rate and breast muscle rate (P>0.05) when Lushi chickens were reared in cages. The hens’ reproductive organs were higher than cocks’ when the chickens were reared in freedom (P<0.01). The relationship between cocks’ slaughter rate and its head weight, neck weight, intestines weight, weight of reproductive organs were no significant correlations in different raising ways(P>0.05); the relationship between hens’ slaughter rate and foot weight, wing weight, intestines weight and spleen weight were significant correlations(P<0.05).
