Determination of Testosterone and LH levels in Growing Shami Male Goats


Abstract in English

This study was carried out at the Shami Goat Improvement Station at Karahta. Twenty one week old Shami male goats were used to measure the concentrations of testosterone and LH hormones in plasma over a period of 21 months, using the Enzyme Linked Immune Sorbent Assay (ELISA), in order to determine the sexual puberty age. All kids were housed and managed under the husbandry regimes applied at Karahta station.
