Abstract : This research aims to identify the biochemical profile of blood in Madura cattle that have experienced repeated breeding. There are ten female cows divided into two groups. In the first group, five cows are being mated repeatedly. The second one has five fertile cows. The observed variables consist of total blood protein, blood phosphorus, and blood ureum nitrogen. The blood samples are taken through the jugular vein and analyzed at the Integrated Research and Testing Laboratory (LPPT) at Gadjah Mada University of Yogyakarta. The biochemical analysis of blood uses the spectrophotometer method with the Microlab 300 photometer. The data are analyzed using a t-test. The blood biochemical profile analysis in Madura cattle shows that they are fertile and have experienced repeated breeding. The phosphorus in the blood of fertile cows is higher than in those that experience repeated breeding. Meanwhile, the highest total protein and blood ureum nitrogen are in the cattle that have experienced repeated breeding compared to fertile cows. It means that the biochemical profile of blood in fertile and repeated breeding cattle is not significantly different.
