KOYUNCU, M. and S. OZIS ALTINCEKIC, 2013. Testicular development and body growth in prepubertal ram lambs of Kivircik, Karacabey Merino and Tahirova in South Marmara region of Turkey. Bulg. J. Agric. Sci., 19: 152-157


An experiment was conducted to compare testicular diameter (TD), testicular length (TL), scrotal circumference (SC), scrotal length (SL) and body weight (BW) gain of 150 ram lambs 50 from each of breed. Measurements were taken at 90, 120, 150 and 180 days of age. Breed was significant (P < 0.05) all of testicular measurements, except testicular diameter at 90 days of age and testicular length at 120 days of age. The various measurements of testis were correlated positively and significantly (P < 0.01) with each other. All characteristics confirm the existence of linear relationship between testicular measurements and body weight when age is taken is constant (P < 0.01).

Key words: Ram lambs; testicular measurements; body weight; Kivircik, Karacabey Merino; Tahirova
