ABSTRACT

In order to study safflower- oil and African palm oil as a source of energy in broiler diets, an experiment was conducted. A completely random design was used. Each treatment was fed by triplicate to 30 unsexed, 1 to 49 days of age broiler Arbor Acres chicks. Chicks were housed in 15 pens with wood shaving litter. Broilers were fed with diets based on sorghum- and soybean meal with palm- or safflower oil at different levels of addition. Diets were formulated for two phases: starting (0 to 3 weeks of age) and growing (3 to 7 weeks of age). The experimental treatments were: addition of palm- and safflower oil. 2.5% and 5%, respectively, to a basal sorghum- plus soybean meal diet with 0% of oil. Results after 49 days for palm- and safflower oil were similar (P › 0.05) for weight gain (2251 g and 2232 g), feed consumption (4854 g and 4742 g) and carcass pigmentation, respectively. However, differences (P ‹ 0.05) in feed conversion (2.18 and 2.15) and feed efficiency (0.464 and 0.471) were found with better results for safflower- with respect to palm oil. Through the slope ratio technique, an energetic value of 81.9 % for chicks of 21 days of age was found in relation to safflower oil (100 %); this means a value of 7,330 kcal/kg of M.E. for palm oil, and a value of 82.8 % for chicks of 49 days of age, which represents a value of 7,410 kcal/kg of M.E.
