RESUMO
The effects of the dietary inclusion of olive pulp (OP) and supplementation birds with a commercial enzyme blend (ENZ) on the performance of broilers were evaluated. Six hundred one-day-old male Ross 308 broilers were divided according to a completely randomized design into 10 treatments in a 2×2×2+2 factorial arrangement, consisting of two olive pulp levels (50 and 100 g/kg diet), two pulp categories (processed and non-processed), the inclusion or not of an enzyme blend supplement, and two control treatments without OP and the inclusion or not of the enzyme blend in the diet. Feed intake (FI), weight gain (WG), feed efficiency (FE), energy intake (EI), energy efficiency (EE), protein intake (PI), protein efficiency (PE), feed cost per kg live weight (FC/kg), and production index (IP) were determined. There was no significant difference (p> 0.05) between broilers fed the OP diets and the control diets for all parameters. Processed OP improved FE (p 0.019 from 1-21 days; p 0.005 from 22-42 days; and p 0.008 from 1-42 days of age) and EE (p <= 0.012 from 1-21 days; p <=0.012 from 22-42 days; and p <= 0.002 from 1-42 days of age). The enzyme blend supplementation did not influence (p> 0.05) any of the studied variables. The inclusion of OP in the diets at levels up to 100g/kg would does not have deleterious effects on broiler production performance.(AU)

The effects of the dietary inclusion of olive pulp (OP) and the supplementation of a commercial enzyme blend (ENZ) on the gastrointestinal tract (GIT) size, and immune and hematological parameters were evaluated. In total, 600 one-day-old Ross 308 male broiler chicks were divided into 6 treatments according to a completely randomized design, in a 2×2×2 factorial scheme, consisting of the dietary inclusion of two olive pulp levels (50 and 100 g/kg in diet), two pulp categories (processed and unprocessed), and the inclusion or not of an enzyme blend. On d 42, birds were euthanized and blood samples were collected, and lymphoid, hematologic, and GIT organs were measured. The inclusion of 100g/kg OP in the diets increased jejunum relative weight (J%) and jejunum length (p 0.05). Processed OP reduced jejunum weight and length, J%, and left cecum length, serum triglycerides and VLDL cholesterol levels (p 0.05). Enzyme supplementation did affect any of the studied parameters (p>0.05). The OP inclusion improved the GIT size, while processed OP reduced GIT measurements and serum lipid levels.(AU)
