摘　　要：The purpose of this study is to evaluate the effect of a low consumption protein-energy supplement that incorporates 15% of coconut pulp expeller in bovine animals. These pasture fattening cattle were checked on daily weight gain, supplement consumption and efficiency of pasture use. This study was carried out in a livestock establishment in the Department of Concepción, Paraguay. A total of 108 animals were selected;castrated male bovines, 342 ± 30.2 of body weight (BW), age average 28 months, Nelore breed distributed in 2 treatments (T1 and T2): T1 = 42 animals;control group (pasture + conventional mineral salt) and T2 = 66 animals;treatment group with a protein-energy supplement (pasture + protein-energy supplement with minerals). In both treatments, the animals grazed on pasture of <span style="white-space:nowrap;"><i></span>Brachiaria brizantha<span style="white-space:nowrap;"></i></span> cv.
