Developmental changes in testicular interstitium in the Najdi Ram Lambs

AbstractThis experiment was designed to study the relationship between growth rate and sexual development in Najdi ram lambs. Forty-five Najdi ram lambs were used in nine age groups (1–9th month age), keeping 5 lambs in each group. Results show that mean testis size and scrotal circumference increased at a constant rate, reaching a maximum value of 392.00±2.00g and 25.00±0.32cm respectively, at the age of 9months. A similar trend of growth was observed for the mean body weight, reaching a maximum value of 40.2±0.20kg at the age of 9months. There was a positive correlation between the increasing rates of body weight and size of the testis. There were significant differences (P
