Pseudopregnancy is a frequently diagnosed reproductive disorder in (dairy) goats. This cross-sectional study evaluates the incidence, possible risk factors and therapies for pseudopregnancy on Dutch dairy goat farms. Two questionnaires, one for farmers and one for veterinarians, were designed and included questions about general farm demographics, breeding management, hormonal oestrous induction, treatment, measures for reduction and stress moments in dairy goats in the period June 1, 2016-May 31, 2017. In total, 43 farmers (21.5 per cent response rate) and 27 veterinarians (22.5 per cent response rate) completed the questionnaire. The annual incidence of pseudopregnancy varied between 1 and 54 per cent per farm, with a mean annual incidence of 17 per cent (95 per cent CI 0.14 to 0.21). In this study, we found a significant association between incidence of pseudopregnancy and a higher percentage of goats with an extended lactation (p<0.0001) and between incidence of pseudopregnancy and the number of ultrasound examinations per year (p<0.0001). The recommended therapy in literature consists of two administrations of prostaglandins. This was only correctly applied by 10 per cent of the farms. On 52 per cent of the farms, an overdose was used comparing to the recommended dose in literature.
