Evaluation of cassava leaf meal (Manihot esculenta Crantz) in feed with enzymes supplementation on broiler performances

Abstract

The research aimed to evaluate the effect of cassava leaf meal with enzymes supplementation in the feed on the performance of broiler. The research used factorial completly randomized design 2x3 on 240 Cobb-strain broilers. There were 6 treatments with 2 factors is used cassava leaf meal (CLM) and enzymes (non-starch polysaccharides and protease) with each dose 250 g/ton feed, i.e. P1: basal ration, P2: basal ration with enzymes, P3: ration with 1.5% CLM, P4: ration with 1.5% CLM and enzymes, P5: ration with 3.0% CLM, P6: ration with 3.0% CLM and enzymes. The variables analyzed were body weight, body weight gain, feed intake, feed conversion ratio, and mortality. The data obtained were analyzed by analysis of variance (ANOVA) and if the results indicated significantly different, then the post-hoc test conducted. The results showed that there was an interaction between CLM and enzymes on the feed conversion ratio (P < 0.05). The addition enzymes can decrease feed conversion ratio (from 1.91 to 1.74) siginificantly (P < 0.05). Addition CLM to a level of 3.0% did not interfere with performance. Enzymes can offset the detrimental effect caused by the use cassava leaf meal in the feed.
