Abstract	Delayed pubertal development and low fertility of Bos indicus x Bos taurus crossbred male cattle and domestic buffaloes is hardly understood hence, a sensitive enzymeimmunoassay (EIA) was developed using the second antibody-coating technique and testosterone-3-O-carboxymethyloxime-horseradish peroxidase conjugate as a label for determination of testosterone in blood plasma. The EIA was validated by standard criteria. Blood samples were collected by venipuncture from growing male cattle (Karan Fries and Sahiwal) and buffalo (Murrah) and testosterone was estimated using the EIA procedure. Plasma testosterone concentrations increased significantly (P < 0.05) with advancing age. Testosterone concentrations were significantly (P < 0.01) higher in Sahiwal males in comparison to Karan Fries males. The low testosterone levels in crossbred than Sahiwal could imply that crossbred males have either not stabilized genetically or not adapted well in Indian climatic conditions resulting in poor libido and poor semen quality. The low testosterone levels in Murrah buffalo males may be the possible reason for delayed maturity in this species. The direct, sensitive EIA validated for estimating the plasma testosterone concentration was reliable for studying the testosterone profile in blood plasma of males. The results suggest that there could be a requirement for higher testosterone secretion by males during early stages of growth for attaining early sexual maturity.
