Performance of broilers fed with highly digestible ingredient in the prestarter and starter raising periods

The objective of this work was to evaluate the effect of the diet, with the inclusion of an energetic-protein nucleus (EPN) composed of highly digestible ingredients, on the productive performance and carcass traits of broiler chicks. The nucleus was composed by degummed soybean oil, pre-gelatinized corn, twice-processed soybean, mannanoligosaccharides and peptides. The total of 864 male AgRoss 508 broiler, with one day of age, were weighed individually and distributed in a randomized block design. Treatments consisted of: T1, control, 0% EPN; T2, 7% EPN (1-7 days) and 3.5% EPN (8-21 days); T3, 14% EPN (1-7 days) and 7% EPN (8-21 days); and T4, 21% EPN (1-7 days) and 10.5% EPN (8-21 days of age). At 21 days of age, body weight, weight gain, average feed intake, feed conversion and carcass and cut-ups yield were not significantly affected by treatments. The EPN inclusion in the diets did not influence the performance, carcass traits and cut-ups of broilers.
