In this study we investigated the potential economic impact of good management of the calving interval on dairy farms. This involved the assessment of economics and production of a sample of farms, selected from the Farm Accountancy Data Network (FADN), and located in Sardinia, Italy. Two farm models were derived from clustering the sample by k-means, which were validated by verifying their consistency in relation to nutritional needs, feed supply and milk production of the herds. Differences in indices of performance and dynamics were found (e.g. ROE is -0.8% vs 4.7%), with evident linkages between economic performance, greater efficiency, reproductive capacity, and potential turnover. The model better performing reflected greater economic feeding efficiency and a shorter calving interval. Hence, management, more than structural aspects, determined the economic results of the sampled farms.
