Heifers received or not energetic supplementation at different phenological stages of grasses (vegetative, pre-flowering and flowering). Experiments involved 360 heifers with initial age of eight months and average body weight of 145 ± 17 kg, on continuous grazing method and variable number of animals. Supplementaed heifers consumed 17.0% less forage and 22.2% less leaf blades than heifers exclusively on pasture. Grazing activity was concentrated in the afternoon shift, regardless of the feeding system and phenological stages evaluated, with the longest event of rumination during the night. Forage intake rate is similar, regardless of supplement intake and phenological stages of grasses. 2016 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303159348012 https://www.redalyc.org/journal/3031/303159348012/ https://www.redalyc.org/journal/3031/303159348012/html/ https://www.redalyc.org/journal/3031/303159348012/303159348012.epub https://www.redalyc.org/journal/3031/303159348012/movil 10.4025/actascianimsci.v38i2.30218 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
