Predicting of abdominal fatness were examined using 120 Arbor Acres
chicks indirect measurements used were information on body weights and some blood
constituents (concentrations of plasma triglyceride and cholesterol). The direct
measurements included abdominal fat weight (AFW) and abdominal fat weight as
percentage of marketing body weight (AFP). The AFW and AFP were highly
correlated with triglyceride (r = 0.78 and 0.81, resp.) cholesterol (r = 0.62 and -0.64.,
resp.) Adjusting the data to fixed marketing body weight reduced the corrlations of
AFW and AFP with body weight and daily gain to negligible values and slight!y
increased the correlations with triglyceride. The inclusion of triglyceride and
cholesterol into one equation was not useful in increasing the accuracy of prediction
(R2= 0.588 VS. 0.551) Adjusting the data to fixed body weight end point improved the
efficiency of triglyceride in predicting AFW by 28%. It could be concluded that the
plasma triglyceride (PTG) content (mg/dl) could be used as a reasonably accurate
predictor of abdominal fatness using these equations: AFW (g) = 6.53 + 1.22 PTG (R2=0.551).
AFP % = 0.486 + 0.116 PTG (R2=0.46).
