Diagnosis and evaluation of the response to the treatment of pseudopregnancy in small ruminants, through ultrasonography and analysis of plasma progesterone concentrations
A clinical and ultrasonographic study has been completed with analysis of plasma progesterone concentrations by radioimmunoassay in three pseudopregnant goats and one pseudopregnant ewe. Persistence of luteal function (> 0.5 ng/ml of plasmatic progesterone) and accumulation of aseptic fluid within the uterus (hydrometra) are characteristics of pseudopregnancy in goats and ewes. Cloprostenol treatment effectively reduced the plasma progesterone concentration to levels < 0.5 ng/ml in all animals and induced a re-establishment on ovulatory activity. The ultrasonic morphology of corpora lutea was not different of corpora lutea during the oestrus cycle.
