A study was under taken on 315 pullets, distributed in 7 treatment groups in deep litter system to assess the effects of replacing maize by apple pomace in the ration at 0, 10, 15, and 20% levels with or without enzyme supplementation, on age at sexual maturity, egg production, egg weight, and mortality. Each gram of multi enzyme mixture contained amylase 2400, hemi-cellulase, 5400, cellulase, 12000, protease 2400 and Beta-glucanase 160 units, respectively. The same was incorporated @ 1g / Kg feed. There was no significant effect on age at sexual maturity among the different groups, though it was numerically higher in the groups in which maize was replaced by apple pomace at different levels irrespective of enzyme supplementation. Numerical decrease in egg production (HD) was observed by replacing maize by apple pomace at 10 and 15% levels with enzyme supplementation, which was not statistically significant, but significant adverse effect was observed in those groups where replacement was made at the same level (10 and 15%) without enzyme supplementation and at 20% level with or without enzyme supplementation. Numerical but statistically insignificant increase in egg weight was observed in the groups in which maize was replaced by apple pomace at 10% with enzyme supplementation and 15% with or without enzyme supplementation, but when the replacement was made at 10% level without enzyme supplementation and 20% with or without enzyme supplementation increase in egg weight was statistically significant. Average feed consumption/bird/day (114 g) was similar in all the seven groups, as restricted feeding was practiced. So far as mortality is concerned in-corporation of apple pomace up to 20% level had no effect on mortality.
