The pig advisory visit in preventive medicine.

An approach to advisory work on intensive pig units is described. Detailed methods of carrying out an advisory visit include the clinical examination discussions and record evaluations, special topic presentations and the report. Check lists are presented for use in different parts of the production system and a suggested preventive medicine programme for a 250-sow herd is described. The economics of the service show a cost factor of only 0.17 per cent of gross turnover and guides to the veterinary time are given.
