Estimation of hydroxyproline and collagen in skin of turkey (Meleagris gallopavo) was done using skin samples procured from 12 birds each of either sex of four to six months of age. The samples were stored at -200 C and the hydroxyproline content of moisture-free and fat-free samples of the skin was estimated. From the values arrived at, the collagen content was calculated on fresh matter basis. Average content of hydroxyproline was 5.20 and 5.30 per cent in male and female turkeys respectively. Collagen content was found to be as 8.16 per cent in male and 8.14 per cent in female turkeys. On statistical analysis, significant difference was not detected in the mean percentage of hydroxyproline and collagen content between sexes. Hence, the skin of turkey with its high content of collagen can be recommended as a source for collagen production in the avian industry. Moreover, with a contribution of 8.43 to 9.65 per cent to the total carcass weight, the potentials of skin of turkey could be effectively harnessed for further processed products.
