Abstract
The study was conducted to determine the relationsh ips between body measurements, scrotal and seminal characteristics using 62 Yankasa rams at th e Teaching and Research Farm of the Department of Animal Science, Ahmadu Bello University, Zaria, Nigeria. Body measurements related positively with testicular measurements (0.40-0.83). Body (0.27-0.4 8) and testicular (0.25-0.48) measurements were positively related to semen characteristics. Howeve r, the relationship between semen pH and sperm concentration was negative (-0.29 to -0.38), with t esticular dimension (-0.30 to -0.38) and with body measurements (-0.29 to -0.38). The study revealed t hat efficient fertility of Yankasa rams and subsequent conception rate in ewes would depend on the interactions of these variables.
