|Abstract: ||Three isonitrogenous diets continuing 20, 30 and 40% wheat bran (WB) were formulated and fed ad libitum to grower-finsher pigs The 20% WB diet was the control diet while the 30 and 40% WB diet were described as the experimental diets and both of these had 50g. of an exogenous feed enzyme complex known as OPTIZYME added to every 100kg. of the diet. A total of 15 pigs in 5 replicates were used for the study which was terminated when the individual pigs attained liveweight of 70 ± 0.5 kg.
The mean values for daily weight gains and feed conversion efficiency were similar (P>0.05) for the pigs fed the 3 diets but mean daily feed intake was highest (P <0.05) for the pigs fed the WB}0 + OPTIZYME diet. The pigs fed the WB40 + OPTIZYME diet also had a significantly (P<0. 05) higher feed intake than pigs fed the Control (WB2Q) diet, Both feed cost and feed cost per kg. liveweight values were decreased as the level of WB was increased despite the extra cost of the added OPTIZYME. The carcass characteristics of the pigs on all the 3 dietary treatments were similar (P>0.05). It was concluded that grower-finisher pigs can be fed as much as 40% WB without any adverse effects on growth performance, except for an increase in feed intake and carcass characteristics. Such high WB plus OPTIZYME were in fact cheaper to formulate and feed.|
