An experiment was conducted with the aim of designing food profiles of dual purpose cows grazing on pastures of Panicum maximum Jacq., associated with native trees of Acacia macracanthain Agricultural Unit “San Antonio”, province of Jaén, region of Cajamarca. Data collection and sample collection were performed during the dry, beginning of rain and rainy season. Fourteen exclosureswere installed on 54 hectares and five Brown Swiss x Creole adult cows on production were evaluated. Forage growth rates and availability were obtained by the method of cutting and separation, feed intake by the method of animal behavior, diet quality by manual simulation, energy requirement by the budget of activities, food profile by balancing between forge demand and supply and grazing plan by the usable forage and forage demand. Statistical analysis was a completely randomized design for forage growth and availability, randomized blocks for chemical composition and selectivity of diets, forage intake and energy requirement and hierarchical design for animal behavior. Forage growth rate ranged from 8.16, 18.42 and 46.28 kg DM/ha/day; forage availability ranged from 2696.9, 4023.3 and 7764.3 kg MS/ha and intake ranged from 11.6, 14.9 and 14.6 kg DM/cow/day for dry, rain and beginning of rain season respectively. Food metabolizable energy concentration was 3.94, 7.00 and 5.23 MJ ME/kg DM and total energy demand by cows was 102.0, 92.9 and 90.1 MJ ME/day for dry, rain and beginning of rain season respectively. Food profile revealed a surplus in the rainy season and a deficit in the dry and beginning of rain season. Grazing plan for the dry season reveals that pastures should be rested. We conclude that the Agricultural Unit is sub using the pasture especially during the rainy season due to the good forage availability and low stocking rate. During the dry season, animals do not meet their nutritional needs due to the limited forage availability and forage low quality forage.
