Abstract: The purpose of this paper is to propose the production frontier model for multilateral productivity comparisions when undesirable products are taken into account and to analyze the technical efficiency with an animal waste in the case of dairy farming. The sub-vector efficiency measures performance in terms of the ability of a producer to expand milk production, given its animal waste and its inputs using a nonparametric programming approach. This approach was concerned to the decomposition of three technical efficiency concepts for this analysis: (1) the pure technical efficiency; (2) the scale efficiency; (3) and, the congestion of animal waste. The data was collected 95 dairy farmers in the eastern part of HOKKAIDO in 1997. The analyzed results were the following: First, the sample mean of overall technical efficiency which incorporates animal waste (HOSCRS) is 1.13099. It was turned out to differ whether or not animal waste management was incorporated. Second, the sample mean of pure technical efficiency (WSW), scale efficiency (WSS) and congestion of animal waste (CONGESTION) are respectively 1.09007, 1.02472 and 1.01479. Third, HOSCRS and WSS vary depending on the farm size. CONGESTION varies depending on the farm size if applied to the comparison between small and large and, medium and large.
