Abstract
The effect of feeding Alocasia macrorrhiza root meal (AMRM) with or without added coconut
oil slurry (COS) on egg production and egg qualities was investigated in a 20-week experiment.
A control diet based on maize and 4 other diets containing 10 and 20% AMRM with or without
COS were fed each to 4 replicates of 10 birds in a completely randomized design. There were no
significant dietary effects on feed intake (FI) and the intake of lysine, methionine and
metabolizable energy (ME). Birds fed the 20% AMRM_COS added significantly less weight
during the experimental period compared to the control fed group. Body weight change (BWC)
did not differ among the AMRM fed birds. Per cent hen-day and feed conversion ratio were
depressed on 20% AMRM and egg weight on 10% AMRM but these depressing effects were
overcome by COS addition. Egg shape index, Haugh unit and per cent shell were not affected by
the diet. It is concluded that AMRM can replace 10% dietary maize without adverse effect on
laying performance but 20% replacement negatively impacts on hen-day and egg weight. These
adverse effects are however, overcome by treating AMRM with COS at the ratio of 9: 1. More
research into higher levels of COS treated AMRM in the diet is warranted.
