英文摘要 | Studies were made to determine the effects of feeding hydrolyzed keratinous protein including hydrolyzed feathers, hog hair and wool residuces, locally produced as a protein supplement on growth rate, feed conversion as well as carcass qualities of the growing-fattening pigs, Three trials were conducted and ninety one hybrid weanling pigs were used. The results are given in tables 4 to 6 respectively. The data indicated that the pigs fed diets containing 2.5 percent of hydrolyzed feather meal, hog hair meal or wool residual meal grew as well as those fed the soybean protein control diet. Growth rate and feed utilization were significantly reduced when 5 percent of these keratinous proteins incorporated in the diet. However, There was no ill effect on dressing percentage of the pigs and its carcass qualities. These results are in agreement with those of Kornegay et al. (1973) reported from feeding the hydrolyzed hog hair meal as a protein supplement for swine at Virginia Polytechnic Institute and State University recently. |
