摘要:

旨在分析运动对鸡肉品质和肌纤维发育的影响,选用36 只3 周龄爱拔益加(Arbor Acres,AA)肉鸡,按体质量相近分为对照组和运动组,实验从第4周开始训练到第9周后结束,为期6 周。在5、7、9 周龄时对肉鸡白天运动量、肌肉品质和肌纤维特性指标进行测定。结果表明:持续训练运动组,每周肉鸡白天活动量均显著高于对照组(P<0.05),中午休憩,运动组节律清晰。在9 周龄,运动组胸肌肉色L*值和a*值、腿肌肉色a*值、肌纤维直径显著高于对照组(P<0.05),运动组腿肌肌纤维密度显著低于对照组(P<0.05)。结论:强制运动可增加肉鸡白天活动量,在持续6 周后显现改善肉色,促进肉鸡腿肌肌纤维发育的效果。

Abstract:

This study aims to analyze the impact of exercise on meat quality and muscle fiber development in broilers.
Totally 36 3-week-old Arbor Acres (Arbor Acres, AA) broilers were selected and divided into two groups according to
similar body weight: control and exercise groups. The experiment lasted 6 weeks (from 4 to 9 weeks of age). The amount
of daytime exercise, muscle quality and muscle fiber characteristics were measured at 5, 7 and 9 weeks of age. The results
showed that the amount of daytime exercise per week of the continuous exercise group was significantly higher than that of
the control group (P < 0.05). The broilers in the continuous exercise group followed a clear rhythm, having a rest at noon.
At the age of 9 weeks, breast muscle L* and a* values, leg muscle a* value and muscle fiber diameter of the exercise group
were significantly higher those of the control group (P < 0.05); meanwhile, leg muscle fiber density of the exercise group
was significantly lower than that of the control group (P < 0.05). Therefore, forced exercise can increase broiler daytime
activity level to improve meat color, and promote the development of broiler leg muscle fiber.

Key words: exercise, trial period, meat quality, muscle fiber development
