Maximising Returns from Beef Progeny Sourced in the Dairy Herd - DB-26-05
Duration 4 years commencing March 2005
Team and Leader L. Dawson, M.A. McCoy and B. Moss
Organisations involved Agricultural Research Institute of Northern Ireland and Department of Agriculture and Rural Development for Northern Ireland (DARDNI)
Background and Summary
There are approximately 298,000 and 307,000 dairy and suckler cows in Northern Ireland respectively. Whilst it is envisaged that post Mid Term Review (MTR) of the Common Agricultural Policy (CAP) the number of suckler cows will decline, it is predicted that the dairy herd will increase slightly.
