Reproductive management of reindeer (Rangifer tarandus)
North American reindeer (Rangifer tarandus tarandus) are seasonally polyestrus short-day breeders. Seasonal ovarian activity begins in late August with an estrous cycle length of 24 ± 3.4 days. Estrous synchronization protocols have been published and are similar to protocols in sheep and goats. Art...
