The use of ally-trenbolone as a progestational agent to maintain pregnancy in ovariectomized bitches.
The administration of the synthetic progestogen, allytrenbolone, at a dose of 0.088 mg/kg/d per os successfully maintained pregnancy in 3 of 3 bitches ovariectomized at 34 to 42 d of gestation and in 1 of 3 ovariectomized on Day 8 or 9 of gestation. However, a dose of 0.044 mg/kg/d per os maintained pregnancy in only 2 of 6 bitches ovariectomized in mid-gestation. Two bitches that had ovariectomies performed on Day 9 of gestation and were supplemented with ally-trenbolone at a dose of 0.088 mg/kg/d per os did not establish a pregnancy that was detectable by mid-gestation. Although inhibited the first 2 d post partum in some bitches, lactation increased sufficiently to successfully maintain pups.
