Prostaglandin F2α (PGF1) was evaluated at various dosages to determine its relative effectiveness to synchronize estrus. The effect of intramuscular injections of 0 (control), 10 and 15 mg PGF during the normal breeding season was studied over a 2-year period using a crossbred ewe flock. Parameters discussed are time to conception after injection during first and second estrous cycles, number of ewes lambing and lambing rate. PGF at 10 and 15 mg was effective in synchronizing estrus between 32 and 80 hours post-injection.
