Abstract: LH, FSH and testosterone variations were compared during the prepubertal period in Romanov and Ile-de-France ram lambs born in the spring. Mean plasma LH levels increased significantly between the 1st and 8th week of age in the Romanov and between the 1st and 12th week of age in the Ile-de-France. At 1 month of age, the number of LH and testosterone pulses per hour was higher in Romanov than in Ile-de-France lambs. The mean plasma testosterone levels, higher in the Romanov, increased from 1 week of age onwards. Mean plasma FSH levels increased from the first neonatal week till the 8th week in the Romanov and till the 12th week in the Ile-de-France. The levels of FSH did not differ significantly between the two breeds. The higher and earlier secretion of LH and production of testosterone in the Romanov might be a cause of its better reproductive performance. |
