摘要: 通过对不同年龄阶段组(以体重阶段作为衡量标准)的长白×荣昌F1代长荣猪的肌纤维面积大小的观察比较,绘制出肌纤维的生长曲线图(累积、绝对、相对生长曲线)。结果表明,长荣猪肌纤维生长的最高峰出现在35~50kg体重阶段;在50~80kg体重阶段,生长强度逐渐降低;到80~100kg体重阶段,稍有回升。公猪肌纤维的生长高峰比母猪出现得晚,但高峰后的较长时间内仍维持了较高的生长强度。高营养水平下与低营养水平相比肌纤维生长得更快。

Abstract: Ninety-six Landrace and Rongchang crossbred pigs were divided into five groups according to their slaughter-weight. And the muscle fiber's area of each age-group were measured, then the growth curve of muscle fiber was drawn. Results indicated that muscle fiber reached their growth summit at the weight of 35~50 kilograms, after that the growth intensity would decrease. The growth rate of muscle fiber were different for different sex and nutrition conditions.

Key words: PIG, MUSCLE FIBER, GROWTH AND DEVELOPMENT
