Abstract Experiments were conducted on 18 Black Bengal goats consisting of six does, six castrated males and six bucks each under grazing and stallfed conditions, in order to determine body composition and energy utilization in three different seasons. Body weight of all goats was maintained throughout the season on para ( Brachiara mutica) pasture. There were no detectable differences between sex, treatment and seasons in gross energy intake. Average metabolisable energy (kcal/kg W 0.75/day) intake throughout the seasons was 109.00 and 115.66 in stallfed and grazing goats, respectively, which provided sufficient energy for maintaining body weight throughout the seasons. Prediction of body composition from antipyrine space gave confirmation of maintenance requirement in stallfed and grazing goats at that level. Grazing Black Bengal goats have the ability to maintain nutritional needs from low pastures by conserving energy expenditures.
