However, the amount of fat deposited in the animal body prior to the trial was not
examined and the difference of body weight between the
animals might have influenced the results. It requires
further studies to conclude this.
Moran16 indicated that swamp buffaloes have a total
nitrogen balance either equal to or higher than that of
Zebu cattle, and that this is generally the result of a
higher nitrogen intake and/or a lower urinary nitrogen
output rather than a lower fecal nitrogen output. These
findings were supported by Devendra5. In the present
study, both species were given almost the same amount
of nitrogen and there was no difference in fecal nitrogen
and urinary nitrogen outputs.
