Hepatic secretion of VLDL was compared in young turkeys and chickens (8 and 4 weeks of age, respectively) and older birds (11 and 8 weeks of age, respectively) reared together under the same nutritional conditions. VLDL, VLDL-TG and total TG secretion rates were higher in chickens than in turkeys. The cholesteryl ester content of turkey VLDL was higher than that of chicken. Differences in the fatty acid composition of the VLDL lipids were observed between the species: the proportion of linoleic acid was greater in turkeys, whereas monounsaturated fatty acids were more abundant in chickens. These results are consistent with the hypothesis of a positive relationship between hepatic lipogenesis, delta-9-desaturation, VLDL secretion and fattening in turkeys and chickens.
在相同营养条件下一起饲养的幼龄火鸡和鸡（分别为8周龄和4周龄）以及老龄禽类（分别为11周龄和8周龄）中，比较了极低密度脂蛋白（VLDL）的肝脏分泌情况。鸡的VLDL、VLDL-甘油三酯（TG）和总TG分泌率高于火鸡。火鸡VLDL的胆固醇酯含量高于鸡。观察到不同物种之间VLDL脂质的脂肪酸组成存在差异：火鸡中油酸的比例更大，而鸡中单不饱和脂肪酸更为丰富。这些结果与火鸡和鸡肝脏脂肪生成、Δ-9-去饱和作用、VLDL分泌与育肥之间呈正相关的假设一致。
