PERFORMANCE OF LAYER HEN FED FERMENTED Jatropha Curcas L. MEAL SUPPLEMENTED WITH CELLULASE AND PHYTASE ENZYME

The objective of the experiment was to study the effect of feeding fermented Jatropha curcas L. meal (JCM) supplemented with cellulase and phytase on the performances of ISA-Brown laying hen aged 25-30 weeks. The Jatropha curcas meal was fermented using Rizhopus oligosporus. In this study 200 laying hens were used and distributed to 5 treatments and 4 replications in Completely Randomized Design. The diet treatments were: R0 = control diet (without JCM), R1; diet contained fermented JCM 7.5%, R2; diet contained fermented JCM 7.5% + celullase 200 g/ton, R3; diet contained fermented JCM 7.5% + phytase 200 g/ton and R4; diet contained fermented JCM 7.5% + cellulase 200 g/ton + phytase 200 g/ton. The parameters observed were feed consumption, hen day egg production, egg mass production, egg weight and feed conversion ratio. The results showed that feeding fermented JCM 7.5%, both enzyme supplemented as well as unsupplemented significantly decreased (P<0.05) the feed consumption, hen day egg and egg mass production. However, the treatments did not influence the egg weight. Supplementation of cellulase (R2) or phytase (R3) improved the feed conversion ratio with the value as same as the R0 diet.
