Abstract

The effect of progesterone (P4) on egg production was investigated using twenty female guinea fowls raised on deep litter. The birds were given feed and water ad-libitum. They were routinely bled by wing jab between the hours of 9.00 and 10.00 am twice a month for P4 determination. Sera harvested from the samples were stored at -20 degrees C until assayed for P4 by Radio-Immuno-Assay method (RIA). Egg production had a very high (p<0.001) and positive correlation with progesterone level. A high value of coefficient of determination (R2 value) was observed, which implies that there is a high accuracy of prediction of egg production from progesterone level.

摘要

使用二十只饲养在厚垫料上的雌性珍珠鸡研究了孕酮（P4）对产蛋量的影响。这些鸡自由采食和饮水。每月两次在上午9点至10点之间通过翅静脉穿刺常规采血以测定P4。从样本中采集的血清储存在-20摄氏度，直至通过放射免疫分析法（RIA）测定P4。产蛋量与孕酮水平呈非常高的正相关（p<0.001）。观察到较高的决定系数（R2值），这意味着根据孕酮水平预测产蛋量具有较高的准确性。
