Abstract:
Methane is an important greenhouse gas so managing livestock to reduce methane emissions is important to alleviate climate change. In North America, it is common to graze cattle on pasture during the growing phase and to finish them in a feedlot. The GrassGro decision support tool (Moore et al. 1997) has been successfully adapted for use in Canada. It has been validated by comparing predictions with data from a 4 year experiment conducted at Brandon, Manitoba in which steers grazed a lucerne/grass pasture at 2 stocking rates either continuously or in a 10-paddock rotation.
