[Resumen].h[electronic resource] aIn: Jornada NESPro, 12., Simpósio Internacional sobre Sistemas de Produção de Bovinos de Corte, 3.,26-28 setiembre, Porto Alegre, Brasilc2017 aLive weight (LW) losses of beef calves during winter has always been a great hindrance in the path of intensification and profitability improvement of extensive livestock farmers, especially concerning native grasslands-based systems placed on sandy soils in Uruguay. Additionally, labour shortage has been an increasing concern to farmers, since both availability and training of human resources have been continuously declining over the years. To address these two issues trough research and innovation, an experiment was set out aiming to determine whether it could be possible to attain similar animal performances through supplementing beef calves in their first winter using self-feeders compared to daily supplementation. aURUGUAY aAUTOMATION aGROUND RICE BRAN aINFREQUENT SUPPLEMENTATION aPELLETED RICE BRAN aSUSTAINABLE INTENSIFICATION1 aLAGOMARSINO, X.1 aMONTOSSI, F.
