Biochemical indicators of fatness in meat-type chickens: lack of correlation between lipoprotein lipase activity in post-heparin plasma and body fat.
1. Possible relationships between fatness and lipoprotein lipase activity in adipose tissue and plasma from heparinised birds were examined in 7-week-old male and female broilers. 2. Total lipoprotein lipase activity in abdominal fat was significantly correlated (r = 0.5) with fat pad weight, but there was no correlation between specific activity of the enzyme and fat pad weight. 3. Lipoprotein lipase activity in post-heparin plasma showed no correlation with either abdominal fat or total body fat content. 4. The results indicate that measurements of lipoprotein lipase activity in biopsy samples or in post-heparin plasma are of no value in predicting the fat content of live birds.
