Resumo: | Nowadays, there is an increasing interest in the exploitation and valorization of agricultural food waste and by-products. At the same time, the growing demand by markets worldwide, especially in Africa and Southeast Asia, can justify the growing interest in the use of by-products for the poultry industry. Olive pulp is one of the most interesting by-products of olive tree farming (typical of the Mediterranean area), being a good source of many biologically active compounds with antioxidant, antifungal, and antibacterial properties. The presence of processed olive pulp in the diet showed to be effective in increasing the weight of specific carcass and offal traits. This work aims at studying olive pulp as a feed supplement in poultry nutrition, by focusing on the effects on broiler carcass and offal. Olive pulp (OP) is one of the by-products of olive tree farming, being the residue of olive cake after it is dried. To evaluate the effects of OP in a diet supplemented with different levels of a commercial enzyme (ENZ) blend on broiler carcass and offal traits, three hundred male broiler chicks (Ross 308 lineage; one-day-old) were divided into ten treatment groups according to a completely randomized design. The treatments diets contained: unprocessed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), processed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), and control groups (without OP, and without OP with ENZ). The OP processing increased breast percentages in broilers. Supplementation with ENZ did not change any of the studied carcass or offal trait values. The presence of OP (50 g/kg) in broiler diets increased the eviscerated carcass, leg, and neck percentage values. The presence of processed OP (50 g/kg) in the diet showed to be effective in increasing the weight of specific carcass and offal traits. |

Nowadays, there is an increasing interest in the exploitation and valorization of agricultural food waste and by-products. At the same time, the growing demand by markets worldwide, especially in Africa and Southeast Asia, can justify the growing interest in the use of by-products for the poultry industry. Olive pulp is one of the most interesting by-products of olive tree farming (typical of the Mediterranean area), being a good source of many biologically active compounds with antioxidant, antifungal, and antibacterial properties. The presence of processed olive pulp in the diet showed to be effective in increasing the weight of specific carcass and offal traits. This work aims at studying olive pulp as a feed supplement in poultry nutrition, by focusing on the effects on broiler carcass and offal. Olive pulp (OP) is one of the by-products of olive tree farming, being the residue of olive cake after it is dried. To evaluate the effects of OP in a diet supplemented with different levels of a commercial enzyme (ENZ) blend on broiler carcass and offal traits, three hundred male broiler chicks (Ross 308 lineage; one-day-old) were divided into ten treatment groups according to a completely randomized design. The treatments diets contained: unprocessed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), processed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), and control groups (without OP, and without OP with ENZ).

The presence of OP (50 g/kg) in broiler diets increased the eviscerated carcass, leg, and neck percentage values.
