Abdominal Fat and Percentage Water as Predictors of Body-Fat in Adult Maned Duck, Chenonetta-Jubata

Abstract

We derived 10 best fit regression equations for estimating body fat mass in maned duck carcasses. Body fat can be estimated from abdominal fat mass (females, R*2=0.86; males, R*2=0.81), percentage water (combined sexes, R2=0.83), and the Child-Marshall index (combined sexes, R*2=0.91). We recommend that body fat be estimated by the Child-Marshall equation where carcasses can be dried, and by abdominal fat equations otherwise.
