Fodder plays an important role for dairy cattle in providing the health insurance, facilitating of growth and fulfillment of optimal reproducibility. Shortage of fodder for the tropics is one of the causes of reduced the efficiency of reproduction because it is always followed by a disorder of reproduction. The scientific study aimed to determine the effect of the fodder on the long of estrus, estrus cycle and calving intervals of dairy cattle. Research conducted in UPTD BPBPTDK of the agriculture department in DIY with the number of 22 tails of cattle. This scientific study conducted by use interviewing method and direct observation. The data obtained, among others: the estrous cycle, duration of estrus, calving interval, SKT (body condition score), content of concentrate, amount of forage, and mineral content. The results obtained are: estrous cycle 26 +- 7.72 days, duration of estrus 15.37 +- 6.2 hours, and calving interval 14.5 +- 5.14 months. Based on the default, the estrous cycle and birth spacing is not accordance with the standards while the duration of estrus still in the normal range. From the data can be concluded that the fodder influences quality of reproductive performance in cattle. Shortages of fodder directly will affect of the lack of protein, whereas the protein serves to produce hormones in the body, it includes the reproductive hormones.The shortages of protein cause lack of reproductive hormones so that it will cause disorders of reproduction as: silent heat and disorder of Ovarium.
