ABSTRACT
Two unbred adult female goats were examined for persistent, inappropriate lactation. Prostaglandin F2 alpha treatment was ineffective in relieving the condition. Over 5 months, 1 goat developed evidence of CNS disease; this same goat had persistently high serum prolactin concentrations. At necropsy, both goats had an acidophilic adenoma of the pars distalis, a condition that, to our knowledge, has not previously been reported in goats. In addition, both goats had pheochromocytomas and cystic endometrial hyperplasia, conditions that are rarely reported in small ruminants. The inciting cause of inappropriate lactation in goats can be difficult to determine. Pituitary adenomas should be suspected when treatment with prostaglandins is unsuccessful, signs of CNS disease develop, or persistently high serum prolactin concentrations are detected.

Treatment of cystic ovaries in a bitch was unsuccessful with human chorionic gonadotropin, but aspiration of the follicles at laparotomy was successful. Follicular aspiration is described, with special emphasis on preventing bursal adhesions. Aspiration of persistent follicles is a simple treatment for cystic ovarian disease that is nonresponsive to parenterally administered hormones. The persistent estrus associated with cystic follicles is a primary cause of cystic endometrial hyperplasia (CEH) and severe cases of CEH are associated with infertility. Rapid intervention (surgical or hormonal) will limit the severity of CEH and, therefore, decrease infertility in breeding bitches.
