Nutritional Significance of Different Fat Sources for Growing Broilers

Increasing the dietary supplementation of a number of fats and oils from 30 to 90 g/kg improved the growth rate and feed conversion of broilers without significantly increasing carcass fat content. Optimum growth responses were obtained with vegetable oils. The concentrations of linoleic acid or unsaturated fatty acids in animal tallows may have a greater nutritional significance than the concentrations of free fatty acids.
