placed in individual cellophane bags and kept deepfrozen
at ÿ20°C prior to whole-body analysis. Again,
whenever it was necessary, adjustments were made
such that the mean group weights for all samples were
identical. The carcasses for dissection were scalded at
80°C in a water tank for about 30s before mechanical
plucking of the feathers. After warm washing, draining
and cooling, the carcasses were eviscerated. The
dressed and eviscerated weights were recorded before
carefully dissecting out the breast, drumstick, thigh
and wing. The corresponding organsÐliver, spleen,
heart, pancreas, gizzard, lungsÐand abdominal fat
were carefully dissected out and blotted free of blood
before weighing. In the present trial the abdominal fat
pad is de®ned as the tissue surrounding the gizzard
and intestines, extending within the ischium, and
surrounding the cloaca, bursa of fabricus and adjacent
to the abdominal muscles.6 All dissections were done
on the same day and by the same person to ensure
uniformity of cuts.
