Those of you who follow me on Twitter or Facebook probably gathered my cattle had a bovine tuberculosis (bTB) test about ten days ago. Those of you familiar with farming and the countryside will have a pretty good understanding of the problems surrounding bTB and the distressing effect it has on farmers, farms and cattle industry. And those of you who aren’t that interested in farming, will, I’m sure, be aware of the debate that rages around badger culling, vaccination and the like.
Personally I feel every test brings us one step closer to the inevitable…bTB breakdown. Illogical? Probably. Or maybe not.
We’ve been ‘upgraded’ to six monthly testing, as the farm’s contiguous. I don’t know what’s changed; we’ve been contiguous to farms suffering breakdowns for a good many years. Anyhow this new status certainly makes me more jumpy.
I guess that it’s here that I should mention that in the twenty years I’ve been farming at Locks (and actually for the whole thirty-five years of my farming career) my cattle, first dairy, now beef, haven’t had a case of bTB. I say this with great trepidation; I really dislike mentioning it. I’m terrified of tempting fate.
Briefly, the bTB skin test takes place over a period of a few days. On day one tuberculin is administered at two sites – the first (or the top spot) is the control – avian tuberculin is used; and the bottom, the second site, is inoculated with bovine tuberculin. Three days later the test is read and a conclusion reached on the size of the reaction.
As we were getting ready on the first day I said to Polly, our vet, “Well, don’t suppose we’ll go clear. Bloody miracle if we do.” And somewhat to my surprise she said “Yes, it will be.” None of that nice reassuring talk… my fault for bringing it up, not hers for being honest!
I firmly resisted any temptation to check for reactions. On the Friday as we were sorting through the cattle before the vet came I mumbled to Olly “She doesn’t think we’ll get through you know.”
“Don’t be such a doom merchant” he snapped back at me. But I noticed he didn’t follow it up with “You’re daft. You always say that. Of course we will. We always do!” (I now know that he’d been checking the animals and had found some substantial lumps!)
Reading the test was heart in tongue stuff; Polly had the callipers (used for measuring the size of the lumps) out for practically every cow. Almost all the animals had sizable reactions to the avian tuberculin (indicating a high incidence of avian TB) but, thank god, no reactions to the bTB. We were clear! A surprise to all of us.
So why? Why did we go clear…?
Because I run a closed herd? Or that we’re organic? Maybe we practice exceptional welfare? Have a healthy badger set? Keep a native breed? Farm extensively? Don’t have tonnes of hard feed knocking around? Or that we are just too darn wet? But others are doing these things and more still suffer breakdowns. It is just luck?
Perhaps not…An intriguing paper arrived last week
