Our aim is to enhance the sustainability of pasture-based livestock agriculture to help deliver net-zero livestock systems by 2050. By encapsulating a whole farm systems approach in our vision, livestock scientists work closely with plant breeders, soil scientists, microbiologists, ecologists and social scientists to deliver productive and resilient agri-food systems. Linking to numerous industry partners from across agricultural supply chains, our impact model utilises a participatory-farmer research approach, to provide insights on barriers to change and the science needed by the industry, to support the adoption of innovation by end-users.

We will help to reduce GHG emissions from ruminant livestock through improved animal nutrition by supplying improved feeds that better meet productive animal requirements, and to optimise feed utilisation to minimise pollutant output.  This involves a combination of strategies, including improvements in ration formulation (feed requirements) to manipulation and replacement of key dietary components (feed supply) that help reduce the environmental impact of animal agriculture.  Through integrating the use of the latest varieties of forage plants and increased understanding of animal biology, we are working towards reducing the GHG emissions intensity of livestock production (grams of carbon dioxide equivalents per kg of product; meat and milk) and ultimately reduce total GHG emissions from livestock agriculture, leading to a net zero future.

Approach

Our research remit includes:

• Net zero carbon grassland-based ruminant systems, including upland grasslands 
• Home-grown high protein feed for ruminants and monogastrics  
• Reducing GHG emissions from ruminants  
• Soil protection and ecosystem services in livestock systems 
• Knowledge exchange and implementing change in grassland agriculture 
• Nutrient use efficiency via soil-plant-animal interactions  
• Agriculture 4.0 and precision technologies, including innovation in silage technology 
• Developing novel agri-food products and improving livestock product quality

At IBERS, we have the unique ability to develop novel plant resources to meet global demands for livestock systems that are sustainable, productive and resilient to the impacts of climate change.
