AgriSearch General Manager Jason Rankin said, “I would like to congratulate David on the successful completion of his PhD.  The publication of these findings is very timely as there is renewed interest in growing protein crops in Northern Ireland.


“AgriSearch has supported numerous PhD studentships over the past 24 years, many of whom now occupy leadership positions within the Northern Ireland agri-food sector.  By supporting PhDs, we are not only conducting research of relevance to our farmer levy payers but also investing in the future of our industry.  We wish David every success with his future career.”


AgriSearch recently published a booklet on the use of home-grown proteins in dairy cow diets which is available to download from the AgriSearch website.



AgriSearch, CAFRE, AFBI and DAERA are holding a webinar on “Growing home-grown proteins and their use in dairy cow diets” on Monday 8th March at 7.30pm.  This will include an overview of the new DAERA pilot support scheme for protein crops, crop husbandry and agronomy of protein crops, farmer experience of growing field beans and the results of recent research at AFBI Hillsborough on the inclusion of home-grown proteins in dairy cow diets.  Further details are available on the CAFRE and AgriSearch websites.
