摘　　要：为研究不同品种鸡蛋品质及蛋黄中热量和性激素含量,该试验以遂昌散养土鸡所产的鸡蛋、市售散装土鸡蛋和普通鲜鸡蛋为研究对象,测定鸡蛋重量、蛋黄干湿重和热量以及蛋黄睾酮、二氢睾酮和雌二醇等性激素含量。结果表明,市售散装土鸡蛋和普通鲜鸡蛋的重量显著大于遂昌土鸡蛋(P<0.05),而遂昌土鸡蛋与散装土鸡蛋的蛋黄干湿重和热量均显著高于普通鲜鸡蛋(P<0.05);遂昌土鸡蛋蛋黄睾酮和二氢睾酮含量均显著低于散装土鸡蛋和普通鲜鸡蛋(P<0.05),而蛋黄雌二醇含量在3种鸡蛋中无显著差异(P=0.145)。The rural free-ranging chicken eggs from Suichang County, saled native eggs in bulk and fresh eggs were used as materials to compare their quality, energy and content of sex steroid hormones in yolk. The weight of eggs, dry-wet weight of yolk, energy and the contents of testosterone, dihydrotestosterone and estradiol in yolk of different varieties eggs were determined respectively. The weight of saled native eggs and general fresh eggs were significantly higher than that of rural free-ranging chicken eggs （P〈0.01）, and the dry-wet weight of yolk and energy of saled native eggs and rural free-ranging chicken eggs were significantly higher than that of fresh eggs （P〈0.01）. While the content of testosterone and dihydrotestosterone in yolk of rural free-ranging chicken eggs was significantly less than that of saled native eggs and fresh eggs, no significant differences of estradiol content in yolk was observed among the three varieties eggs （P=0.145）.
