| Popis: | Introduction. Beef production is affected by stationarity forage production and fed cost. Feed frequency evaluations according to pasture could suggest an appropriate practice for profitability improvement. Objective. To evaluate technically and economically the frequency of supplementation of Brahman fattening steers in grazing. Materials and methods. In the middle valley of the Sinú river, Colombia, 108 steers were used distributed in a split-plot design into three pastures (Cynodon nlemfuensis, Megathyrsus maximus, and Brachiaria hybrida, main plot) and three supplementation schemes (subplot): daily (STD), every two days (SDpM) and without supplementation (SS). The daily weight gain (GPD) and morphometric characteristics were evaluated in steers. In the carcass: weight, yield, length, leg perimeter, fat thickness, and compactness index. The biophysical data results fed the financial evaluation of the implemented technology. Results. An interaction of pasture and supplementation frequency over daily weight gain was detected (p |
