豁眼鹅、皖西白鹅和浙东白鹅肌纤维特性的比较

研究旨在通过测定豁眼鹅、皖西白鹅、浙东白鹅肌肉纤维直径、横切面积和肌纤维的密度,探讨不同鹅品种的肌纤维特性差异.结果表明,豁眼鹅胸肌肌纤维直径、横切面积显著大于浙东白鹅、皖西白鹅(P< 0.05),而肌纤维密度表现为相反的趋势.豁眼鹅的腿肌肌纤维直径和横切面积显著大于皖西白鹅(P< 0.05),而豁眼鹅的腿肌肌纤维密度显著小于皖西白鹅(P< 0.05).品种内不同性别之间部分指标也存在显著差异,主要表现在皖西白鹅和浙东白鹅的肌纤维横切面积和直径上.相关性分析表明,肌纤维的直径与肌纤维横切面积呈极显著正相关(P< 0.01),肌纤维直径和横切面积与肌纤维密度呈极显著负相关(P< 0.01).由此可知,不同品种间肌纤维特性存在差异,同品种间不同性别间的肌纤维特性也存在差异.

Comparison on Muscle Histology Characteristics in Huoyan Geese,Wanxi White Geese and Zhedong White Geese

The study was aimed to explore different varieties of geese''s muscle fibers characteristic by measuring diameter, cross-sectional area and density of muscle fibers of Huoyan geese, Wanxi White geese and Zhedong White geese.The results showed that diameter, cross-sectional area of pectoral muscle fiber in Huoyan geese was significantly greater than others (P< 0.05), while density of the muscle fiber showed the opposite trend.In diameter and cross-sectional area of leg muscle fiber, Huoyan geese was greater than Wanxi White geese (P< 0.05), but the former was less than the latter in the aspect of muscle fiber density (P< 0.05).Some indicators were also significantly different between the varieties of sex mainly in cross-sectional area and diameter muscle fiber of Wanxi White geese and Zhedong White geese.Correlation analysis showed the diameter and cross-sectional area of muscle fiber was significantly positive correlation (P< 0.01), what''s more, the relationship of muscle fiber diameter, cross-sectional area and density was significant negatively correlated (P< 0.01).In conclusion, there were differences between the characteristics of different varieties of muscle fibers, among the same breed, differences also existed between the genders.
