Abstract.

Ten dairy herds reporting acute fertility problems were investigated by analysing records and cows, metabolic profiles, tests for infectious agents and milk hormone assays. The main problems were : heat detection (2), endometritis (3) and inadequate nutrition (5). In one herd no cause has yet been identified. On all farms the problem had been present from the start of the breeding period. Management changes, delayed analysis of herd records and over-estimation of forage nutritive value were underlying problems. A diagnostic analysis/decision process to highlight problems early is essential to minimise loss.
