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. |
