Prediction of carcass composition of turkeys by blood lipids

Prediction of percentages of carcass fat or abdominal fat pad by blood plasma concentrations of triacylglycerides (TG) and nonesterified fatty acids (NEFA) was examined in growing turkeys fed diets low in fat. Both TG and NEFA were determined under ad libitum feeding and after overnight fasting cond...

Zusammenfassung:	Prediction of percentages of carcass fat or abdominal fat pad by blood plasma concentrations of triacylglycerides (TG) and nonesterified fatty acids (NEFA) was examined in growing turkeys fed diets low in fat. Both TG and NEFA were determined under ad libitum feeding and after overnight fasting conditions. Abdominal fat and blood plasma TG were significantly correlated (P less than or equal to .01). Males and females did not differ in NEFA concentration under ad libitum feeding, but males had higher concentrations of NEFA after overnight fasting (P less than or equal to .05). The concentration of NEFA was not correlated with abdominal fat (P greater than .05).
