狮头鹅和乌鬃鹅不同生长阶段肌纤维发育规律的研究
|
摘要
为研究狮头鹅和乌鬃鹅在不同生长阶段肌纤维的发育规律,分别选取健康的1、40和120日龄乌鬃鹅和狮头鹅,屠宰并取其胸肌和腿肌做石蜡切片,观察并测定两种鹅不同部位不同时期肌纤维的直径和横截面积.结果表明两种鹅1日龄胸肌肌纤维差异不明显,腿肌肌纤维横截面积和直径差异显著(P<0.05);40日龄两种鹅胸肌肌纤维横截面积差异显著(P<0.05),但胸肌直径和腿肌的直径和横截面积差异不显著(P>0.05);120日龄两种鹅胸肌肌纤维和腿肌肌纤维的横截面积和直径差异极显著(P<0.01).研究结果表明乌鬃鹅肌肉纤维在1至40日龄期间生长发育迅速,但40日龄后肌纤维生长潜力不如狮头鹅.
In order to study the development of muscle fibers at different growth stages of Shitou and Wuzong geese, we collected chest and leg muscles of three Wuzong and Shitou geese at the age of 1, 40 and 120 days, respectively. Paraffin sections of chest and leg muscles were observed under the microscope, and the diameter and cross-sectional area of muscle fibers in both two geese species were measured. By section observation and analysis, we found that at the age of 1 day, the chest muscle fibers were not significantly different between goose species, while the leg muscle fibers were significantly different(P<0.05)in the diameter and cross-sectional area. At the age of 40 days, there was a significant difference in the cross-sectional area of chest muscle fibers between goose species(P<0.05). However, the diameter of the leg muscle fibers and the diameter and cross-sectional area of the chest muscle fibers were not significantly different(P>0.05). At the age of 120 days, the difference in the diameter and cross-sectional area of leg and chest muscle fibers were extremely significant between goose species(P<0.01). These results showed that the muscle fibers of Wuzong geese grew rapidly during the period from 1 to 40 days, but the growth potential of muscle fibers after 40 days was slower compared with Shitou geese.
