This collaborative project between University of Glasgow, Aberystwyth University, International Centre for Tropical Agriculture (CIAT), and University of Antioquia aims to improve cattle productivity on Colombian pasture-based farms by using a multidisciplinary approach that will link forage productivity and quality to animal productivity and farmer attitudes and practice. It will use a combination of remote sensing of forage production and animal behaviour together with measurements of nutrient utilisation and system losses to determine ways of improving the efficiency of animal growth and help reduce the environmental burden of cattle production.
