Anestrus is a functional disorder of reproduction cycle in cattle which characterized by the absence of estrus signs. Anestrus is caused by many factor and it decreases productivity and reproductivity, so that the prevention and control anestrus were needed. The objectives of this study were to determine the prevalence, factors associated with anestrus and blood biochemical profile in fertile and anestrus beef cow. This study used a cross-sectional design, conducted on 228 beef cows which were examinated by rectal palpation in five sub-district in Grobogan district. The sampling was conducted using multiple stage sampling method proportionally. Simple random sampling was done at the level of subdistrict and village, and the livestock as the smallest unit were taken as a cluster. The questionnaire were collected and processed using Statistics for Windows Version 8 software. Analysis used a univariate analysis, bivariate analysis with chi-square (χ2) and the odds ratio (OR), and multivariate analysis with logistic regression. The study to analyze the blood biochemical profile (glucose, total protein, cholesterol, calcium and phosphorus) was conducted on 40 beef cows (20 anestrus beef cows and 20 fertile beef cows) were selected at random. Blood serum biochemical test was performed in the Integrated Research and Testing Laboratory (LPPT) UGM. Blood biochemical profiles were analyzed by descriptive. The results showed that the prevalence of anestrus in beef cow at livestock and farm level were 18.4% and 19.2% respectively. Risk factors that had association with the increasing incidence of anestrus in beef cow were lactation level retained placenta, dystocia, feed straw, and postpartum estrus. Whereas, risk factors which had association with the increasing incidence of anestrus at farm level were the farmer’s experience in raising livestock that less of two years and a dirty cage conditions. Blood biochemical analysis showed that the glucose, total protein, cholesterol, calcium and phosporus level in beef cows which suffer anestrus and fertile cows, were still in normal range. From the result, it can be concluded that anestrus in beef cow was caused by multifactor, and blood biochemical profile in anestrus beef cow were still in normal range.
