never heard that one before
being a sceptic....maybe the vet has an 'arrangement' with aforementioned societies? our vet I know from inside info, doesn't do anything that will save you money (puts a massive mark up on meds etc!)
First time I had goats tested the vet filled a form in after looking through and shuffling my paperwork about (leaning in the back of her car), then I had a phone call from SAC, asking about what scheme I was in and various other questions.
Last time I had BGS forms ready filled in, much quicker, vet just took sample, matching sticker on phial and form. job done. Doesn't cost anything to use the form.
If it saves vets time, surely that keeps everybody happy, they won't like paperwork any more than us?
(if the cost of visit is based on time that should save you money?)
