    Iodine deficiency in cows

    Has anyone had this problem what were the symptoms and what did you do about it ?

    The vet said we may have this in the cows and he took the thyroid from a calf to try to comform it

    Tracesure Cu/I bolus - available from Mole Valley.

    Think there was an article about it in ine of the dairy magazines we get, never had it here though, but do have some Iodine in the minerals.

    Re: Iodine deficiency in cows

    We feed minerals but the vet said there is not enough iodine in them

    A next door farmer had this problem last year and lost a few calves so we fed iodine salt on the silage in the winter as a precation

    As we have lost a copple of calves and this is what he has put it down to the vet has now told us to poor 1% iodine on the backs of are autumn calvers that start to calf in about 6 weeks

    He recons this is becomeing a big problem

    Re: Iodine deficiency in cows

    how do. we've had this problem for a few years now, calves getting full term then dying just before or during calving, or if they were alive they'd be real dopey. did try tubbys with 2000 or 2500 mg of iodine, helped a bit, but the only thing that seemed to work was the tracesure cu/i bolus, but this year we still lost 3 or 4 calves with it though. a couple of our neighbour has started complaining of this problem lately, would really like to know the cause of it. bolus your cows now and you might catch the autumn calvers in time.

    Re: Iodine deficiency in cows

    I cant remember how [I will try to find out] but the vet did say that spikeing or lifting the grass ground would help we put it down to the 3 wet years we had and compaction

    this is suck cows we have you are right calves are dopey and dont wont to suck and dont live long if they are born alive that is

    Re: Iodine deficiency in cows

    Our cows had iodine deficiency. Symptoms were cows starting to calve, having the water bag and then couldn't be bothered to push the calf out. When we got the cow in to assist we'd find the calf presented correctly and only a small pull required. Calves were sometimes a bit small and dopey.

    We now bolus the cows with Tracesure cu/i which have vit E, selenium, iodine and copper. Our neighbour does his twice a year as he felt that doing them once wasn't enough.

    Re: Iodine deficiency in cows

    We had the same problem last year in our autumn calving herd but we were low in selenium as well and have been told that the whole of the UK is the same we have used tracesure this year and have had a price for Cow Care drench from Lloyds Agri which you give at drying off and then again at first service,that to has all the minerals a cow needs and is supposed to help tackle embryonic death.

    Re: Iodine deficiency in cows

    by coincident then, we subsoiled all the fields where the cows are in the spring, they been a lot dryer this year, so be interesting to see if its made a difference by next years calving. sucklers we run as well, we only had about 20 when it first hit, and after loosing 8 or so calves a year, it was getting a bit depressing!!

    I see there is a heffer springing to calve I just hope that the iodine I put on her back has had time to work as at todays prices every calf lost is alot of money if you cant get another calf to put on.

    Tracesure cu/i were cheaper with Wessex animal health than Mole valley this year and last. 01425 474455.

    If they're big cows give them two doses.

    Ideally you'll want one of those head scoops. Bolusing isn't one of my favorite jobs and I've been promising myself I'd buy a scoop but it's still on the shopping list I'm afraid.

    Re: Iodine deficiency in cows

    Iodine deficiency has become an inreasingly common problem sine permissable levels of Iodine in mineral supplements were reduced by the EU a couple of years ago. This was done because of a perceived risk of Iodine overdose to breast fed babies and infants.

    The irony is that other sources of Iodine eg: boluses, seaweed meal, etc can still be used, in addition to a regular mineral. Joined up thinking..or what ?

    Re: Iodine deficiency in cows

    Hi,

    A very experienced vet that used to cover me when farming an iodine deficient area of Scotland told me to spray a small amount of iodine (10% stuff you use on navels) on their backs.... a wee squirt thats all....about a month before calving and do it every week as they go to the trough.  They either lick it off or it gets absorbed into their skin.   I never had a problem with doppy calves on that farm.  (after doing that).    I have since moved farms (just as Iodine deficient).  I have changed tack, I now sprinkle a bit in their troughs so that they still have to lick it when feeding....just a bit to stain the trough...without putting them off their barley.  Touch wood iodine deficiency is nt a problem... It s cheap....and you have nothing to loose....but sleepless nights!!

    Good. The tracesure boluses may solve other problems for you too. Since using them our calves seem a lot stronger and alert when born.

    Re: Iodine deficiency in cows

    Is it not easier to feed a dry cow mineral mixed in the feed to guarantee intakes of it everyday?

    That's what i do and it seems to work well.

    What is the iodine you put on their backs? we have lost a few calves this year and have just had the last one post mortemed and its looking like iodine deficiency but we already use the tracesure with iodine boluses and have done for a few years so we're a bit narked that we have this problem tbh!

    My neighbour has to do his cows twice a year as once doesn't give them enough iodine. Not sure if he said he was giving them a double dose as well.

    We sell all calves in October (towards the end) then the cows stayed in, got tracesure bolused mid Nov and the first one calved on christmas day and the calf never stood up, we tubed it with milk and did our best to get it to stand up but by the next morning it was dead. I would have expected the bolus to have still been in the system after just over a month (max)? then we lost another calf just into the new year but it was born dead.
    could a lack of iodine also cause the cows not to cycle properly?

    I think you may have got it the wrong way around topdog. Bolusing a month before calving doesn't give the bolus enough time to work perhaps ? In any case from what you describe I'd say that the calf wasn't suffering from iodine deficiency. Probably Vit E or selenium ? Do you also have probs with retained afterbirths ?

    I was told that iodine deficiency caused some infertility but it's main symptoms were cows being lazy at calving. We had many cases where we'd see a cow starting to calve with the water bag out etc. We'd then go back in say half an hour and find the cow lying down and chewing her cud without a care in the world. After getting them in to investigate we'd find the calf correctly presented and only a light pull was needed. Also the calves would sometimes be quite small and lethargic.

    I would suspect that bouluses would be more effective if given in early to mid pregnancy, but I'm no expert. We bolus all our cows pre turn out, whether they're spring or autumn calvers and we rarely see any problems since we started using the boluses. The ones we use are Tracesure Cui.
