[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  aExtensive livestock production systems face major constraints such as labour shortage and the need to intensify production to maintain and/or increase the farmers´ profitability.
