Evaluation of prostaglandin F2a, estradiol benzoate and deslorelin acetate protocol for oestrus induction in bitches

Inter-oestrus interval in bitches is relatively longer than in other domestic animal species, efforts have been brought about to reduce it due to the increase in the pet market. The aim of this study was to test the efficacy of a prostaglandin F2a, estradiol benzoate and deslorelin acetate protocol...

The aim of this study was to test the efficacy of a prostaglandin F2a, estradiol benzoate and deslorelin acetate protocol for oestrus induction in bitches. Six healthy female dogs were used. Two bitches were on day 75 of postpartum anoestrus, the other four dogs were in dioestrous and a luteolysis was induced in those ones with prostaglandin (2.5 ng/kg/24h/4d sc). All bitches received a single dose of estradiol benzoate on day 75 of anestrous (postpartum or induced).
