Advancing sustainable forage-based livestock production systems in Colombia (CoForLife)

This project 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. This collaborative project brings together a range of expertise from the UK and Colombia to address ways to increase the uptake of improved forage crops for dairy and beef production. Remote sensing (using drones and satellite data) will be used to assess plant growth and nutritional composition, providing spatially explicit data on when, where, and how nutritious the forages are. This will be combined with new ensiling techniques to conserve forages at times of good growth for use in times of low feed availability (i.e. the dry season). Animal behaviour and digestive physiology will be monitored on farms to determine cattle use of feed resources in relation to their growth characteristics and linked to the remote sensing data. Improved efficiency of use of captured carbon and nitrogen for productive purposes is balanced with potential pollutant outputs, and the fate of excreted nitrogen in soils will be determined to investigate the effects of forage plants on efficiency of nitrogen recycling (and losses) from the production system. The economics of the use of novel forage resources will be modelled to investigate the potential benefits to farmers of planting new grazing pastures, and to help them take investment decisions under changing climate conditions. Farmer behaviours in the use of improved forage resources and methods on their farms will be studied to analyse their motivations and potential barriers to the implementation of more efficient farming practices. Engagement with farming communities is an important element of this work, because their knowledge and understanding is vital to successful design, implementation and dissemination of the project work and outputs.
