The Productivity Evaluation of Madura Cattle Under Beef Cattle Research Station Breeding Management

Madura cattle is one of the local beef cattle that have high adaptability to the influence of tropical environments and is one of the local-germplasms that must be maintained and increased in productivity. This study aimed to evaluate the productivity of Madura cattle under-Beef Cattle Research Station (BCRS) Breeding Management. The Madura cattle were 138 dams and 6 sires, which come from the selective-collection. They were developed under BCRS breeding management, such as, application of natural mating in Litbangtan communal-pen-models with the sex ratio of 1 male for 15-20 females. The parameters were first mating age, first partus age, calving interval (CI), days open-(DO), calving rate (CvR) and calf crop (CC). The results showed that the first mating age of Madura cattle was (average ± SE) 23.2±1.26 months,-first partus age 32.7±1.25 months. Madura cattle had the shortest CI 358.1±22.1 days with DO 78.1±22.1 days, CvR and CC 70% and 90%,-respectively. The age of first mating and partus of Madura cattle come from the selective collection were similar with Madura cattle in their-original place. It was because of the identical mating pattern; while the CI and DO value got better with time of observation. It was concluded-that developing Madura cattle under BCRS breeding management improved their reproduction value.
