Ovarian hypofunction is the highest incidence of reproductive disorders in Central Java, breeders losses due to the long calving interval and increased maintenance costs. Feed quality is considered to be a cause of ovarian hypofunction, but there are also other factors that cause disease. The purpose of this study was to determine the prevalence and risk factors for ovarian hypofunction in beef cattle, as well as a model for predicting ovarian hypofunction in Jepara Regency. A total of 304 beef cow from 176 breeders were selected by formal random sampling in 14 villages in 7 sub-districts with multiple stages. Anamnesis was conducted to farmers and rectal examination of beef cow to determine the reproductive status, and questionnaires for animal husbandry and individual animals level. The results showed prevalence of ovarian hypofunction 8.88% and risk factors that have a relationship are frequency of supplementary feed (OR = 12.77), ownership of one animal (OR = 0.34), main feed (OR = 9.59), breed type (OR = 0.37), cows age (OR = 0.33), lactation status (OR = 0.07) and calf weaning time (OR = 0.03). Model of disease formed are Ln P/1-P = 0,484 + (2,247xPKUT) + (-4,406xSAPH).
