Hi everyone,
We have a recurring problem of certain lambs (particularly boys for some reason) going really squitty after weaning. It's not caused by worms or cocci and it goes on for months, so can't be due to fresh or wet grass.
One thing I haven't managed to rule out is cobalt / selenium deficiency, so I'm thinking of giving both our ewes and lambs boluses this year (probably '
smartrace' or similar) to see if that makes any difference.
So, before I do, can anybody tell me how to actually give a bolus? Is it just like giving a drench, or will I need the vet to show me how, the first time around?
Also, is there anything else I should be aware of before supplementing cobalt / selenium / idodine ?
Thanks in advance folks!
