Skeletal Muscle Growth, Development and Histological Characteristics of Arbor Acres Broilers
摘要
Abstract
The skeletal muscle growth, development and histological characteristics of Arbor Acres ( AA ) male broilers were investigated and the models of allometric relationships between skeletal muscle fiber diameter and live weight, muscle weight were established in order to provide a theoretical basis for nutritional factors regulating the growth and development of skeletal muscle. A total of 84 one-day-old AA male broilers ( one group) were randomly designed into 6 replicates with 14 broilers per replicate. Broilers were fed with standard diets that were formulated according to the nutrition levels recommended by National Requirement Council (1994). Feed and water were fed ad libitum. The results showed as follows: the equations between live weight, breast muscle weight and thigh muscle weight and age were better fitted with Gompertz functional e-quation (R2≥0. 97). The growth inflexion for live weight, breast muscle weight and thigh muscle weight were the ages of 41. 18, 35. 67 and 38. 63 days, respectively. Skeletal muscle fiber diameters were increased with the days of age increasing, the diameters and growth intensities of different skeletal muscle fibers were dif-ferent on the same day of age. The max growth intensity for breast muscle, biceps femoris muscle and gastroc-nemius muscle fiber diameters was found at the age of 7 days, 14 and 35 days and 14 days, respectively. The power regression could better fitting the correlation between muscle fiber diameter and days of age ( R2≥0. 91). The correlations between breast muscle, biceps femoris muscle, gastrocnemius muscle fiber diameters and live weight were better fitted with power regression and polynomial regression, polynomial regression, pol-ynomial regression and linearity regression, respectively. The correlation between breast muscle fiber diameter and breast muscle weight was better fitted with power regression and polynomial regression (R2≥0. 99). The correlation between gastrocnemius muscle fiber diameter and thigh muscle weight was better fitted with polyno-mial regression (R2 =0. 97). The correlation between biceps femoris muscle fiber diameter and thigh muscle weight was better fitted with logarithmic regression and polynomial regression (R2≥0. 99). All the results of F-test were significant (P<0. 01).关键词
