运动对肉鸡肉品质及肌纤维发育的影响
Effect of Exercise on Broiler Meat Quality and Muscle Fiber Development
摘要
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.关键词
