Abstract
Seven “male-type” freemartins, 34-38-month old were described. The gonads were situated in three cases in the abdominal cavity, in one case in the inguinal canal and in the other three subcutaneously. The freemartins with gonads in the subcutaneous exhibited masculinised behaviour and the circulating concentration of testosterone were significantly higher (P<0.001). Fluctuation were not detect in the secretory patterns of testosterone in the freemartins while a fluctuation characteristic of seasonal influence was evident in the control rams (P<0.01)I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
