Performance of broiler chicken fed on different levels of fat energy from crude palm oil and refined palm products.

Day old broiler chicks were fed with corn-soya based rations with added fat of crude palm oil (CPO), CPO: refined palm products (RPPS) blend and RPPS until 7 week old. There were 8 treatments ration, with 5 replications of 20 birds per replicate. CPO was used as positive control against RPPS. The eight ration used were, T1 4.5% CPO, T2 4.5% RPPS , T3, T4 and T5 with 4,5% added fat respectively with blend of CPO:RPPS of 25:75, 50:50 and 75:25. In three other ration RPPS was used, at 5.5%, 6.5% and 7.5% for T6, T7 and T8, respectively. The birds were housed in cages provided with feed and water adlibitum. The objectives of this study was to evaluate the effect of feeding different level of feeding different level of CPO:RPPS blend and RPSS in growing and finishing broiler ration. Total weight gain of starter broiler was very different ( less than .01) among treatments. rations with straight RPPS, T6, T7 and T3 were most effective (p less than .01) to support weekly weight gain of starter broiler compared to positive control, negative control and CPO:RPPS blend. Their total feed consumption was higher (p less than .05) compared to others. This was an indication that the ration containing straight RPPS was very palatable and readily consumed by the broiler starter. During first week on starter ration the feed efficiency was different (p less than .05) among treatments. However, there were no different (p less than .05) in feed efficiency among treatments at week 2 and 3. During week 4,5, and 6 the broiler finisher were fed with finisher ration. The total weight gain of the bird were very different (p less than .01) among treatments. The performance from group that were fed on ration T6 and T7 showed the best with highest cumulative body weight gain. Cumulative total feed intake on week 6 wasdifferent (p less than .05) among treatments. Overall feed efficiency was different (p less than .05) among treatments. The feed efficiency of the treatments were 1.900, 1.937, 1.941, 1.958, 1.999, 2.009, 2.012 and 2.032 for T6, T3, T4, T7, T8, T1 and T2, respectively. The RPPS which was formulated at MPOB using refined palm products was very effective energy supplement and was much better than CPO for broiler starter and finisher diets. RPPS was technically effective to substitute CPO at equal amount or even higher.
