It's been 5 years since we last had a farm inspection, so I've been looking over things and reviewing the medicine record book, in anticipation of a visit from Inverness. Last time they didn't examine the spreadsheet I was using, just asked me to confirm that I was keeping a record. I would appreciate your experience on a couple of points:
1. How precise do you need to be in the column which identifies the animals treated with a medicine? It's easy enough to list tag numbers for small batches, like drenching the tups but that seems impracticable for large numbers of ewes. Is it enough just to put eg "40 ewes"? It's very rare that you can write "all ewes" as there is usually 1 or 2 errant beasts who have managed not to be present.
2. What is the acceptable method of disposing of unused vaccine and antibiotic?
