摘要

用放射免疫法测定了16日龄至100日龄各组哈伯德鸡血浆睾酮(T)和δ 4-雄烯二酮(δ 4)浓度的变化。血浆睾酮较低,在第16 ~ 63天保持相对稳定(0.10 ~ 0.30 ng/ml),但随后迅速升高(第65天0.32 +/- 0.07 ng/ml vs.第100天1.49 +/- 0.27 ng/ml)。在同一时期,δ 4水平也增加了(第65天为0.23 +/- 0.06 ng/ml,第100天为0.75 +/- 0.18 ng/ml)。在生命的最初几周,4-雄烯二酮比睾酮占优势。[δ 4]/[T]比值在第30天和第40天之间达到最大值,然后逆转为负值。讨论了结果与其他种鸡所得结果的关系。

[Variations of plasma levels of testosterone and delta 4-androstenedione in growing Hubbard cockerels].

Variations in the plasma concentrations of testosterone (T) and delta 4-androstenedione (delta 4) levels were measured by radioimmunoassay in individual young Hubbard Chickens from the age of 16 days until 100 days. Plasma testosterone was low and remained relatively stable between days 16 and 63 (0.10 to 0.30 ng/ml), but increased then rapidly (0.32 +/- 0.07 ng/ml on day 65 vs. 1.49 +/- 0.27 ng/ml on day 100). During the same period delta 4 levels increased too (0.23 +/- 0.06 ng/ml on day 65 vs. 0.75 +/- 0.18 ng/ml on day 100). During the first weeks of life, delta 4-androstenedione prevailed over testosterone. The [delta 4]/[T] ratio reached a maximum between days 30 and 40 and was then reversed to negative values. Results are discussed in relation to those obtained for Chicken from other stocks.
