Sažetak
Ovarian cysts (OC) are among the major factors affecting dairy cattle fertility due to their impacts on reproductive performance. Extension of the calving-calving interval and the costs of treatment
associated with this pathology are the main sources of economic losses for the dairy industry. This study involved conducting an epidemiological survey relating to ovarian cysts in cows based on the observations of veterinary practitioners in Algeria. This survey was performed using a questionnaire distributed to 103 practicing veterinarians in different regions of Algeria. According to the responses, OC dominated all ovarian diseases, followed by smooth ovaries and ovarian adhesions. Ovarian tumours were encountered very rarely. In general, veterinarians considered any follicular structure greater than 20 mm in diameter and persisting for at least 10 days to be cystic. The aetiology was multifactorial, and the following were cited: alimentation, high milk production, puerperal pathologies (metritis, retained placenta), postpartum, age, and winter season. Anoestrus was often the most observed behaviour in cystic cows, accompanied by changes in the genital tract, namely the cervix and uterus. As a consequence, in most cases, OC was associated with a delay of first insemination and conception. The use of hormones, especially PGF2α and GnRH, to treat OC was the most widely used method in the field. Clinical recovery was obtained approximately 11-15 days after the beginning of treatment, though the risk of recurrence was appreciable. The majority of vets interviewed promoted the prevention
of OC. They advised breeders to improve feeding and hygiene conditions, especially during calving. Medical prevention was based on the use of hormones (PGF2α and GnRH). Though the survey showed varying results, they were generally consistent with the literature.
