Conteúdo: 	The effect of the deferral period (E1 = January 20, E2 = February 3, E3 = March 6, and E4 = March 17) and of the utilization period (every 28 days between July 21 and October 27) on the production and quality of Centrosema pubescens was studied at the Empres de Pesquisa Agropecuaria de Minas Gerais, Brazil (EPAMIG; 19 28S and 44 15W). Treatments were laid out in na experimental design of split with four replications. In the first harvest, after 120 days growth in the rainy period, the average DM production of C. pubescens was higher when deferral took place in January (E1 0 1.74 = 0.75 t/h: and similar in the rest of the periods (E2 = 1.04 = 0.44, E3 0 1.03 = 0.33, E4 = 0.98 = 0.45 t/h. These differences remained constant even during the critical dry season period from June to Setember. Average green-leaf content in the dry period was similar for the fourtn period (E4 = 51%) IVDMD of the whole plant (47%) was independent from the deferral period; on the contrary, it varied in the green leaves among periods (E1 = 55 + or -1.8%; E2 = 51 + or - 7.8%; E3 = 48 + or - 5.1%; E4 = 53 + or - 2.2%). Results emphasize the importance of quality of this species when deferring forages for critica periods. In this sense, legumes such as Centrosema pubescens, capable of maintening green leaves during the second half of the dry period, hve advantages opposite to grasses.
