Abstract

The objective of this experiment was to evaluate the used of Brassica oleracea var capitata by product as feed of local turkey kept intensively in confinement housing. Twenty two toms of 8 weeks of age were used in this experiment. Average body weight were 534,37 ± 32,12g. The treatment of this experiment consisted of four diets, T0 (basal diet), T1 (basal diet 95% + brassica 5%), T2 (basal diet 90% + brassica 10%) and T3 (basal diet 85% + brassica 15%). Basal diet composed of broiler commercial feed, fish meal and corn meal. Basal diet containd 24% crude protein and 2900 kkal/g Metabolisable Energy. Experimental design used Completly Randomize Design. Data colected were analized by ANOVA. Result of this experiment showed that brassica in diet significantly decreased feed consumption, energy consumption, protein consumption, and increased carrcas persentage (p < 0,05). Body weight, body weight gain, carcas weight, feed convertion, protein efficiency ratio were not significantly different. Based on this experiment diet contained 15% brassica (T3) was optimal for growing turkey. key words : turkey, brassica, performance, protein efficiency.
