The aim of this work was to evaluate the effects of five feeding strategies on the apparent digestibility of the nutrients and net energy for lactation balance. Five Holstein cows were assigned in a (5X5) latin square design. The strategies were: total mixed ration: TMR; separated ingredients: SI; sorghum silage + concentrate and separated spineless cactus: S+C/SC; spineless cactus + concentrate and separated sorghum silage SC+C/S; spineless cactus + sorghum silage and separated concentrate: SC+S/C. The apparent digestibility of dry matter (DMD), organic matter (MOD), crude protein (CPD), ether extract (EED), total carbohydrates (TCD), nonfiber carbohydrates (NFCD), neutral detergent fiber (NDFD) and TDN values (67,16; 68,97; 77,24; 52,97; 66,72; 73,39; 53,42; 62,73%, respectively) was not affected (P >0,05) by feeding strategies (MC, IS, S+C/P, P+C/S, P+S/C). The energy utilization was better when spineless catus was associated with sorghum silage
