liz_tigress:it's more economically viable to put livestock down than to pay for vet bills
There is no question that it is not economically viable to have a Vet treat sheep. However, most sheep farmers will call out the Vet at some time during lambing. Most farmers can handle the many problems themselves and also give subsequent treatment and nursing to ewe and lambs, but there are few farmers that would not hesitate to call the vet as soon as they have reached the limits of their own, often considerable, experience and knowledge. I have not yet met a sheep farmer who, on those occasions when he has called the Vet, has done it because he wants to protect his money. He calls out of a sense of duty and loyalty to the Ewe.
In the case of sheep, because of their low value, (not withstanding recent improvements) farmers have taken more responsibility for dealing with animal health and consequently many vets have seen that side of their business decline. Vets, like farmers. live in a world of birth and death and face their consequences regularly. This has led to their being able to better cope with the decisions required when resolving conflicting emotions, values and time scales. For example, recently, I had a tricky case with a Ewe which, after five days nursing, I correctly diagnosed but called the Vet to confirm. He did so and advised that "Additional treatment was possible but outcomes uncertain and that, because of her pain, (which he could alleviate) we should put her down. At that point he could have given injections but being a farming vet I fetched the shotgun and we shot her.
Had I been a townsman with a pet, the Vet would undoubtedly have been told to give treatment which could have run into hundreds of pounds with no greater guarantee of success. This illustration will I hope, confirm your view that more than economic factors are in the minds of farmers when they use the services of Vets for both livestock and pets.
I have also found that Farm Vets have a different approach to farming clients than their other clients. They assume a greater knowledge of animal behaviour, physiology and biology as being held by farmers and also assume a less sentimental view towards the animal is held. (Farmers rarely let affection or respect for the animal descend into sentimentality)
An early point you made, is that it is becoming more difficult in parts of the country to get farming vets. I guess a number of reasons lies behind this such as a diminishing base of stock farmers, greater reward from treatment of pets, more women going into the profession and a decreasing pool of farming families from which vets often came. In addition the educational requirements for potential Vets compare favourable with those of GPs and the disparity between incomes, working hours and life style may contribute to some potential vets choosing medical practice instead.
Increasing costs and complexity of running an independent surgery associated with regulation, labour, space and local authority costs, may also militate against Vets choosing to offer services to farms.
