The use of legumes and leguminous by-products within dairy systems is compared at Crichton Royal Farm: Home-grown feed, which is not purchased except minarals against fully purchased feedstuff - contrasing technical performance as well as GHG emissions and nutrient use efficiencies are expected to arise from the diets, genotypes and housing systems containing leguminous co-products or legumes grown in the UK.
Recent research has shown that the carbon footprint of milk produced on Irish dairy farms is approximately 1.23 kg CO2eq. per litre of fat and protein corrected milk. The objective is evaluate the feasibility of a Low Carbon System of milk production where emissions per litre of FPCM are substantially lowered, while maintaining current levels of milk output per ha and profitability.
