Ovulation and lambing rates in ewes actively immunized against androstenedione
Journal of Reproduction and Fertility
|May 1, 1978
Abstract:
In ewes immunized against androstenedione, ovulation rate was increased (P less than 0.001) although the number of live lambs/nursing ewe (1.37), but not the sex ratio (10 females:1 male), was similar to that of controls (1.33).
