Abstract
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).
