Summary

Analyses were carried out on a flock of Peul ewes which ran permanently with rams. Average age at first lambing was 739.5 ± 50.5 days and was significantly affected only by the season of birth, the most favourable period being the post-rains of October and November. Lambing intervals averaged 341.9 days. The cold dry season (December-February) was the least favourable period as reflected in lowest lifetime productivity of young.
