An experiment was conducted to determine the effect of three oil sources with the inclusion of three levels on some performance variables, carcass quality, and broiler organs. The sources used were palm oil (Elaeis guineensis), chicken oil, and Sacha inchi oil (Plukentia volubilis). A total of 324 female Ross 308 line were assigned in a completely random design to nine treatments with six repetitions of six birds per repetition, which were fed with a diet based on corn and soybean meal containing 3, 6, and 9% inclusion of each one of the oil sources for the periods between 8 to 21 days of age and 22 to 42 days of age. Live weight and feed consumption data were recorded weekly to calculate the feed conversion ratio, considering mortality. On day 42, one female broiler from each repetition was randomly selected, weighed, and sacrificed, to obtain upgraded data characteristics from the carcass. The results suggest that there was no significant difference in animal response variables or channel quality. Regarding the carcass variables and some poultry organs, the only one affected by the source was the deposition of abdominal fat. Sacha inchi oil produced carcasses with a lower average of abdominal fat in relation to weight and slaughter, with no differences between palm and chicken oils.
