Sažetak
The utilisation in pig fattening of diets with various proportions of dried olive cake, i.e., olive by-product resulting from centrifugal separation, was investigated in 60 Swedish Landrace x Large White crossbreds (30 castrates and 30 gilts). The pigs were divided into three equal groups (10 + 10): two experimental groups, fed with a fodder mix containing 50 g/kg and 80 g/kg respectively of dried olive cake, and a control group, fed with the same mix but minus the cake. The experiment lasted 90 days. For the first 45 days the pigs were given the starter, and for the second 45 days the finisher, mix. Throughout the whole period, pigs in both experimental groups achived greateraverage body mass and mass gain than the control animals. Concurrently, castrates in all three groups became heavier and demonstrated greater mass gain than did the gilts. While supplied respecively with the finisher mix throughout the whole test period, pigs fed mices with 50 g/kg of dried olive cake demonstrated significantly greater feed consumption than those fed without the cake and than those fed mixes with 80 g/kg of cake. While suplied with the starter mix, pigs fed mices with 50 g/kg of dried olive cake achived the lowest feed conversion rate, whereas those supplied with the finisher mix achived the highest. Throughout the entire period no significant differences were observed in feed conversion rate among pig groups.
