Description
The present work aimed to evaluate the potential incorporation of olive by-products olive cake (crude olive cake, exhausted olive cake without and with olive oil and two-phase olive cake) in the diet of Bísaro pigs, a local breed reared in Trás-os-Montes region (northeast of Portugal) and to study its effect on the animal´s growth traits and carcass characteristics. The experiment was carried out on 40 Bísaro pigs selected from animals delivered for slaughter to Bragança-Portugal. Five different treatments with different olive cakes (T1 – basal diet; T2 – 10% crude olive oil; T3 – 10% olive cake two phases, T4 – 10% exhausted olive cake; and T5 – 10% exhausted olive cake + 1% olive oil) were. Body weight, pH (1 and 24 hours after slaughter) and carcass weight were similar in all treatments and no significant differences were observed. No significant differences were found between the treatments for the carcass measurements performed, except for the longissimus dorsi length at seventh rib (P<0.05) varying between 75.9 (T3) and 87.3 (T5) mm and fat depth measured at the last rib (P3 measurement) varying between 91.1 (T5) and 99.2 (T4) (P<0.05). The data provide the definition of a standard carcass for the breed and this ratio of body weight. Results indicate that this oil by-product can be used to feeding Bísaro pigs
