dc.description.none.fl_txt_mv Variables inherent to the forage and animal component were evaluated to design feed profiles of dual-purpose cows grazing Panicum maximum Jacq in a dairy farm in the Peruvian tropics. The forage variables were growth rate and forage availability and the animal variables were the chemical composition of the diet and feed profile. The experiment was carried out in the dry, early rainy and rainy seasons. Fourteen enclosures were installed in 41.9 ha and five Brown Swiss x Creole lactating cows were used. Forage growth and availability rates were obtained through cutting and manual separation, diets were obtained by manual simulation, energy requirement through the budget of activities and feed profile through the balance of forage demand and supply. A completely randomized design was used for forage growth and availability, and random blocks for chemical composition. The forage growth rate varied between 8.16 and 46.28 kg DM/ha/day; forage availability between 2696.9 and 7764.3 kg DM/ha for the dry and rainy seasons, respectively. The concentration of metabolizable energy in the forage was 3.94 and 5.23 ME MJ/kg MS and total energy demand of cows was 102.0 and 90.1 MJ ME/ day for the dry and rainy seasons, respectively. Feed profile revealed a surplus in the rainy season and a deficit in the dry and early rainy seasons. It is concluded that the farm is underutilizing the pasture, especially in the rainy season, due to good forage availability and low stocking rate.
Se evaluaron las variables inherentes al componente forrajero y animal para diseñar perfiles alimentarios de vacas de doble propósito sobre pasturas de Panicum maximum Jacq en un fundo ganadero de la selva alta peruana. Las variables forrajeras fueron tasa de crecimiento y disponibilidad de forraje y las variables animales fueron la composición química de la dieta y el perfil alimentario. El experimento se realizó en las épocas seca, inicio de lluvias y lluviosa. Se instalaron 14 excluidores en 41.9 has y se trabajó con cinco vacas adultas Brown Swiss x criollo en ordeño. Las tasas de crecimiento y disponibilidad se obtuvieron mediante el método de corte y separación manual, la dieta se obtuvo por simulación manual, el requerimiento energético a través del presupuesto de actividades y el perfil alimentario mediante el balance entre la demanda y oferta de forraje. Se utilizó un diseño completamente al azar para crecimiento y disponibilidad de forraje, y bloques al azar para la composición química. La tasa de crecimiento de forraje varió entre 8.16 y 46.28 kg MS/ha/día; la disponibilidad de forraje entre 2696.9 y 7764.3 kg MS/ha para las épocas seca y lluviosa, respectivamente. La concentración de energía metabolizable en el forraje fue 3.94 y 5.23 EM MJ/kg MS y la demanda total de energía de las vacas fue 102.0 y 90.1 MJ EM/día para las épocas seca y lluviosa, respectivamente. El perfil alimentario reveló un excedente en la época lluviosa y un déficit en las épocas seca e inicio de lluvia. Se concluye que el establecimiento ganadero está subutilizando la pastura, especialmente en la época lluviosa, debido a la buena disponibilidad forrajera y baja carga animal.
