Introduction Brachiaria brizantha and Cynodon nlemfuensis are grass species used by cattle owners in México and in many other countries for fatteningstock. Seasonal variation along the year causes great nutritional and energetic variations in their morphological composition and in green and dry forage production (Morais et al., 1998), nutritive value,structural carbohydrates, lignine and maturity (Van Soest, 1982). Its nutritional and energetic characteristics are not always known in Sinaloa, México and during fattening, they affect results. Forthese reasons, conducted this experiment to characterize nutrient and energy profile of Brachiaria brizantha and Cynodon nlemfuensis in Sinaloa, Mexico. Materials and methods Site of experiment Thisexperiment was carried out at Puerto Rico Dairy Ranch located in the San Lorenzo valley in Culiacán, Sinaloa, México. Soil condition Soil analysis was made at the beginning of the experiment. Conditionof the grasses The grasses evaluated Brachiaria brizantha and Cynodon nlemfuensis weren’t growing rapidly at the beginning of the experiment because of the relatively cold temperatures of winter.Management of grasses
