Re: Mastitis in heifers pre-calving


mckeague,

I use a desinfectant called stallosan that I treat the stalls with, it's some granulated stuff that you can spread just by trowing a hand full in each stall.
It works fine whenever the scc start to increase.
the ones that are already infected I would treat like any other case of mastitis.
Get a sample of milk and culture it to find out what antibiotic you need to use and treat accordingly.
I have always believed in massive treatments for mastitis and avoided the "mild" stuff perhaps thats why I dont have a problem with samples comming back resistant to penicillin.

Streptococcus uberis


Am,

while we are on the subject of mastitis, can anyone suggest how to effectively treat strep uberis mastitis in the milking herd. We have been struggling with this bug for nearly a year now, and every time it hits, it takes a few cows with it, just because we can't get it cleared out of the udder. A typical case would appear to be cured, and when finished treatment would choose some seemingly random time to reoccur.

We have tried the usual penicillin, framacetin etc intramammaries, coupled with tylosin intramusclar for prolonged periods, sometimes for five days after all clinical signs have gone.

The cubicles are well bedded with sawdust mixed with a small amount of hydrated lime. Crystallised formaldehyde is applied once every three weeks (I think this may be Broa's Stallosan).

Many of the cases seem to get sorted out in the dry period, but that doesn't help a fresh calver that takes it.

Re: Streptococcus uberis


We had this problem a couple of years ago so you have my sympathy.This bug is very difficult to cure in individual quarters and quite infectious.To stop the problem getting out of hand you need to deal with the persistant offenders that are are threat to the rest of your herd.Culling is the most drastic option alternatively if that would be too painful you could kill off individual quarters,The vet gave us some disinfectant,50 ml up the quarter and then repeat 48 hours later,obviously don't milk the quarter out and make sure the quarter is not clinically infected at the time.We have a cow that we treated this way that recently completed her 100 tonnes,she would not be here if she was still milking on four quarters!

I'm sure you know that wearing gloves at milking time and using a powerful teat dip will help the spread of infection,also dipping the clusters in a bucket of water with a dash of hypo after ANY high cell count cow has been milked will help.

Re: Streptococcus uberis


Thanks much Mark. H*ll of a problem as you know. Robot milking, so the milking routine is more or less preset. I take it the disinfectant kills the quarter off for all future lactations? And what is/are the active ingredient(s)? What scale of problem did you have, and was it erradicated or are there still occasional cases? Are there no effective antibiotic treatments? The next one for us to try is Cephaguard. Is there any point?

Someone has suggested that our sawdust bedding (which is stored in a large pile and inevitably heats a little) could be problematic. Do you have a view?

Appologies for so many questions all at once!

Re: Mastitis in heifers pre-calving


The sawdust isn't going to help because as far as I know strep uberis is an environmental bug. Have you thought of using kiln dried sawdust, that’s what we use.

We changed to Cephaguard at the time and still use it. It’s not going to solve the problem though.

We haven't eradicated the problem but have it at a manageable level and our scc is running at 120 compare to 180-200 18 months ago. We culled 2 or 3 offenders in full production and killed off a couple of quarters(permanent I'm afraid).There are one or two cows that have high cell counts that have not been got in calf and will go eventually.
I don't know how the robots work so I'm not sure how much infection could be transmitted cow to cow that way.

If you can get kiln dried sawdust I'm sure it would help.

I don't know what the active ingredients were in the disinfectant I'll email my vet when he gets back from Skiing in Austria!!

Re: Mastitis in heifers pre-calving


What about bedding with sand? Marvellous stuff for reducing mastitis. We get virtually no mastitis with the cows in sand cubicles.

Would it work for your housing?

Not sure how the robot would cope with teat preparation.

Re: Mastitis in heifers pre-calving


Mark. Thanks for the reply. Not everybody wants to talk about a problem that is hurting them.
     Kiln-dried sawdust! Didn't know it existed, but it sounds rather luxurious (on the same lines as sun-dried tomato). I don't think we have the like. Our resources may be rather more limited. There are two sawmills about twenty miles away and thats all I know of. We have been using sawdust for years without a problem. But then, we didn't have this bug before.

Big Bird. Thankyou for the sand. Our cows spend their lives on top of slatted tanks. Sand I'm sure is good, but you can see where it would end up on my farm. The robots prepare each teat between two brush rollers which are disinfected with aq. acetic acid between each cow milking. They also rinse-wash the clusters with clean water between each cow milking.

Does anyone operate auto-scrapers, and do they lead to cleaner cubicle beds?

Re: Mastitis in heifers pre-calving


We also use sawdust/wood shavings, maybe this is where our problem is coming from. We do dust twice a week with lime but maybe this would be better mixed with the sawdust and done twice a day. By the way the heifer that got mastitis and prompted this thread cleared up within 2 days, she went 2 days clear then came through the yard trailing a leg - when her teat was pulled nothing came out cept a hissing sound, quarter lost, heifer nearly lost!!!! Anybody know what it was??? Vet told dad but he was that pickled with the problem that he can't remember what he was told!!

Sounds like clostridiae to me but that usually kills them, never had one to survive yet. emoticon
