Pseudopregnancy (hydrometra) is a pathological condition of the uterus which is characterized by accumulation of aseptic fluid in the presence of a persistent corpus luteum. It forms a major cause of subfertility in goats. The aim of this study was to determine the percentage of occurrence of the pseudopregnancy on Croatian farms of Saanen goats, as the representatives of highly dairy breed. The study was performed through a period from mid-August 2010. till the end of November 2011. During the study progesterone profile of goats was analyzed for a period of a month and a half during the beginning of the breeding season (transitional period) and in the off-season period after light treatments were performed and it was also made ultrasound diagnosis of pregnancy 35th to 50th days after mating. Study on farm OPG Moravec included 79 goats (39 that were kidded during the first half of March 2010., and 40 goats that were kidded during the first half of March 2011.). On the farm OPG Zadravec and OPG Malinaric study included 42 goats (22 +20). After analysis of progesterone profiles of goats and performed ultrasound diagnostics, during the season 2010. we have determined that the incidence of pseudopregnancy ranged in values of 7.69 %, while in 2011. varied between 2.5 % and 5 %, or in average of 3.65 %. All of the goats with diagnosis of pseudopregnancy were treated with the prostaglandins (PGF2α), in two occasions, the second application after 11 to 12 days. Goats discharged of uterine fluid and showed signs of oestrus behaviour within 1.5 to 2.5 days after the start of the treatement, were mated after the second injection of prostaglandins and eventually all remain pregnant. Prognosis of pseudopregnancy is favorable if it is diagnosed on time, most of the animals after efficient treatment with prostaglandins manifested signs of estrus behaviour and after mating ramain pregnant.
