Timing the breeding season of the ewe: what is the role of daylength?



Timing the breeding season of the ewe: what is the role of daylength?



Reproduction, Nutrition, Developpement 28(2b): 365-374



The role of daylength as a "zeitgeber" in the onset of the reproductive period in sheep is evaluated in this review. Although sheep are regarded as a short-day breeding species, the reproductive period of the Suffolk ewe begins on daylengths which are, on average, 2.5 h longer than those on which it ends. The reasons for this apparent anomaly are considered.
