| Abstract: | Four gilts with delayed puberty were treated with 1 mg of Gn-RH intravenously. Three of the four gilts showed heat after treatment and heats recurred thereafter at normal intervals in these three pigs. All pigs responded with increased blood content of LH after injection of Gn-RH (1.45–6.1 ng/ml). The failure of one pig to exhibit heat after the injection of Gn-RH could not be explained by the resulting LH response.The results of this limited trial indicate that one cause of delayed puberty in gilts may be an insufficient gonadotropic release. Further studies are required to elucidate the reasons for the difference in sexual and ovulatory responsiveness of gilts with delayed puberty to Gn-RH. |
