Abstract

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.

摘要

对7周龄的雄性和雌性肉鸡进行研究，以检验肝素化禽类脂肪组织和血浆中肥胖与脂蛋白脂肪酶活性之间可能存在的关系。2. 腹部脂肪中的总脂蛋白脂肪酶活性与脂肪垫重量显著相关（r = 0.5），但该酶的比活性与脂肪垫重量之间无相关性。3. 肝素化后血浆中的脂蛋白脂肪酶活性与腹部脂肪或全身脂肪含量均无相关性。4. 结果表明，活检样本或肝素化后血浆中脂蛋白脂肪酶活性的测定对于预测活禽的脂肪含量没有价值。
