Lupins in sustainable agriculture (LISA)

Research/Industrial partners: IBERS (Institute of Biological, Environmental and Rural Sciences, Aberystwyth University; formerly IGER), The University of Newcastle, PGRO, TAG, Germinal Holdings, AHDB Pork, DairyCo, ABNA and Kelvin Cave Ltd.

Sponsors: This project is being funded under the Defra LINK Sustainable Arable programme 

Project duration: 2004 - 2009 

Aims and objectives

  • To evaluate the advantages and disadvantages of lupins for organic and conventional use in the UK
  • To assess the potential of two different varieties of lupin (Wodjil and Prima) for inclusion in pig diets
  • To develop DNA markers that can ultimately make the selection of improved genotypes faster and more precise 

Findings to date

  • Lupins have a protein content at least 10% greater than peas or beans, with a reasonable amino acid balance
  • Results indicated that dry matter and nitrogen digestibility were poorer for both lupin varieties than for soya (Wodjil: 83-84% of soya and Prima: 90-91% of soya); these values indicate only the apparent digestibility, which may overestimate true amino acid contribution
  • Inclusion of lupins may make diets less palatable and it was noted that feed refusals were greater with diets containing lupins, careful diet introduction would therefore be necessary
