Abstract |
In this paper, changes in the concentration of inosine monophosphate (IMP) of muscles in Taihe Silkies chickens from 2 to 28 weeks of age were studied. The results showed that: (1) with increasing age, IMP content of muscles decreased continuously. (2) the relationship between body weight and IMP content of musculus pectoralis major was significantly negative (p<0.01), so was body weight and IMP content of musculus peronaeus, and their coefficients of correlation were -0.45, -0.38 respectively; the relationship between IMP contents of musculus pectoralis major and that of musculus peronaeus was more significantly positive (p<0.01), and its coefficient of correlation was 0.59. (3) by multiple regression analysis, changes of IMP content of muscles depended on the weeks of age and body weight. (4) from 2 to 28 weeks of age, the heritabilities of IMP content of musculus pectoralis major were calculated between 0.33-0.48, and those of musculus peronaeus were calculated between 0.51-0.69. |
