Abstract: The aim of the present study was to evaluate the effect of different doses dexamethasone and progestagen-PMSG on fertility and prolificacy in Kivircik ewes during the breeding season. For the experiment, 100 ewes were divided into four groups, with 25 females in each group. Groups were fluorgestone acetate (FGA, 30 mg), administered via intravaginal sponges. Experimental groups 2, 3 and 4 mL dexamethasone injection were given 72 h before mating season. The fertility rates control, 2, 3 and 4 mL were 88.0, 92.0, 100.0 and 100.0%, respectively (p<0.05). The prolificacy rates for the same groups were 122.7, 130.4, 144.0 and 156.0%, respectively (p<0.01). The injections dexamethasone significantly increased lamb birth weight and daily weight gain for 60 days (p<0.05).
