“…Measurement of the scrotal circumference (SC) is highly correlated with testicular weight in dairy and beef bulls [11] and constitutes an essential part of the breeding soundness evaluation [9]. Colas et al, [12] and [13] and Folch [5] state that in the young animals this measure is useful to make an early preliminary selection based on more or less gonad development, because the testicular size of the young lamb and the same animal at the adult age are highly correlated, so this measurement can utilized to sort out the best producers of semen from the age of 8 months. The same approach can be seen in our sheep farms.…”
