Effect of Using ẞ-Pentosanase Enzyme in Feed on Broilers Performance

The aim of this study was to determine the effect of using the ẞ-pentosanase enzyme on the zootechnical performance of broiler chickens. The study was carried out on 165-day-old broiler chicks, divided into 5 batches of 33 chicks each (Batch 1: control without incorporation; Batches 2, 3, 4 and 5: with enzyme incorporation (at a dose of 25g enzyme/100kg feed) during the start-up, growth, finishing and rearing phases respectively). Data analysis showed that incorporation of the ẞ-pentosanase enzyme had a very highly significant influence (P<0.001) on weight at 21 days and 42 days, highly significant (P<0.01) on weight at 47 days and significant on weight at 56 days of age. This incorporation had a very highly significant influence (P<0.001) on weight gain between (0 and 21) days, highly significant (P<0.01) on weight gain between (22 and 42) days, significant (P<0.05) on weight gain between (43 and 47) days and non-significant (P>0.05) on weight gain between (48 and 56) days and with a remarkable improvement in feed conversion. We conclude from this study that the incorporation of the ẞ-pentosanase enzyme into broiler feed had a significant positive effect on broiler zootechnical performance, notably average weights and daily weight gain in the first two growth phases, with a notable improvement in feed conversion. However, this incorporation had no effect on the above-mentioned zootechnical parameters during the last growth phase (between 48 and 56 days).
