Abstract

The present study was conducted to assess the response of intravenous  administration of hCG on plasma testosterone, estradiol, dehydroepiandrosterone  (DHEA) and estriol levels in breeding Sahiwal bulls. Six breeding Sahiwal bulls  were injected intravenously with 1500 I.U hCG followed by blood sampling at an  interval of every 15 minutes for 4 hours. Plasma testosterone, estradiol, DHEA and  estriol were estimated and the values were calculated by elaborating the standard  curve. It was observed that testosterone level declined within 15 minutes of hCG  administration followed by gradual increase until 3h. Fluctuation among the  DHEA levels at different time intervals were somewhat near to the basal levels  and similar to testosterone. However, non-significant differences were observed in  plasma estradiol and estriol following hCG administration. It was concluded that  endocrine status of Sahiwal bulls could be assessed between 1.25 to 3 hours of 1500  IU of hCG administration.
