N2 - This paper presents the report of a committee of the American Association of Bovine Practitioners recommending methods for calculating several basic indices of reproductive performance on dairy farms. Indices presented are: overall reproductive performance, intensity of estrus detection, conception efficiency, pregnancy losses. reproductive culling, and reproductive efficiency in herds using a bull. Data from a hypothetical dairy herd are provided and example indices are calculated.
