Extract

Evidence has been found in growing broiler chickens that the presence of added fat in the diet can enhance the energy utilisation of the non-lipid portion of the diet due to an interaction between fat and the carbohydrate component of the diet (Mateos & Sell, 1980; 1981). Also, while it is known that a negative correlation exists between the degree of saturation of the fat and its digestibility in monogastric animals (Freeman, 1983), few studies have examined a range of degrees of saturation with growing pigs. The present study aimed to investigate the effects of both the concentration of added fat and the degree of saturation of the fat in the diet on the performance of growing pigs. The fats used in the study were beef tallow and soya oil and are regarded as relatively saturated and unsaturated fats respectively and the assumed digestible energy (DE). values for these fats were 32.1 and 36.0 HJ/kg respectively.
