    A five-year study (2008-2012) was made to determine the bioproductive and financial behavior derived from the structures and resources available on ten private rustic farms, in the province of Ciego de Avila, Cuba. The pastureand forage yields were estimated for evaluation of their contribution and efficiency. Decomposition of seasonal time series was performed to determine the annual behavior of births, through a multiplicative model. Variance analysis for farm comparison was based on efficiency of dairy production, and financial indicators (SPSS, 15.0. 2006). Overall, the availability and quality of pastures and forages was insufficient, with negative annual forage balances. The farms evidenced birth seasonability, particularly farm No. 7 (April-May). However, the general birth rates were very low, as a result of inadequate reproduction management. The best productive and financial results were observed on farm No. 7 (1 061 kg/milk/ha/year, and $ 0.87 CUP/kg of milk produced, respectively)
