Fall Equine Worming Strategy

posted by Horse Owner Today    |   October 21, 2011 17:36

Q:  Over the past year I have heard/read bits and pieces regarding worming & the possibility that wormer may become a prescription product.  Why?

A:   I don’t think the generic wormers will ever become prescription products but if newer stronger generation wormers become available they often will be scheduled as prescription products due to the risk of indiscriminate use.    A good example of this are the wormers that have been developed to kill round hook and tapeworms.  Many people will purchase the “plus” product simply because it is more expensive or kills more worms even though tapeworms are not common in horses.   If the product is sold only through veterinarians the proper indications for it use can be given and the product can be used properly.

Q:  We are having frost every night, what is the best worming strategy for pasture horses in fall.

A:   In Saskatchewan a good Ivermectin based wormer for the fall should be given any time now.  For young weaned or yearling horses and follow up treatment should be given in a month.

Equine Warts

posted by Horse Owner Today    |   October 19, 2011 20:11

Q: I had a 1 year old warmblood gelding come board in the spring and at that time he had warts on his nose. They have since gone away but now my 1yr old and 3 yr old warmbloods have warts all over their noses and spreading. Are the warts contagious? Is there anything I can do to help get rid of them. Will they go away?


A:  They will go away on their own. They may be somewhat contagious if they rub noses but only young horses are susceptible. You can speed up resolution by crushing one with pliers which may alert the immune system to clear them. Other home remedies like toothpaste and other concoctions have no active ingredient against the papilloma virus but the act of applying them likely disrupts some of the lesions and acts the same as crushing. ~Dr. Lisa Wayman~

Side Effects of Equine Vaccines

posted by Horse Owner Today    |   October 8, 2011 18:08

Q: My question to you this morning is this. What are the side effects of equine vaccines? I. E.: rabies, west nile & evwt-fr. Thanks

 

Answer by Dr. Lisa Wayman:  Side effects are rare [a few out of hundreds] and the same horses often react each time more than others.   A local inflammatory reaction can occur which is a slightly tender flattened lump at site of injection if present will be there the next day. This subsides in few days with bute or no treatment. Some horses get muscle soreness in whole neck after injection so much that they are too painful to raise and lower head. Those ones should be vaccinated in hind end or get bute at same time. Any injection through non sterile skin can cause an abscess that will show up and enlarge over a week. When mature this abscess is opened and flushed by vet. A very few will have an allergic reaction manifested by shaking, depression or collapse. This happens within 5 min. If a vet gives vaccination injection they will be able to give emergency drugs as soon as it occurs to reverse the allergic shock, but is rare enough than owner vaccination of own horses is not irresponsible. This kind of response can occur with any drug injection not just vaccines.
I like to give vaccines in the soft muscle in front of the shoulder rather than higher up neck. I find far fewer sore swellings at this location.

 

Answer by Dr. Domoslai:  Vaccines have all been extensively tested on numerous horses prior to the release for sale and are extremely safe.  A risk does exist and an occasional horse will have an adverse reaction.  These reactions can vary from mild swelling and pain to death.  An anaphylactic response is the most severe side effect of vaccine and I always have on hand, epinephrine in case the horse has an allergic response.  If your horse has had adverse reactions in the past all booster shots should be risk assessed with your veterinarian before giving them.  There have been many rumours and anecdotal reports of wild side effects basically blaming vaccination on everything from worms to poor behaviour and these reports have to be taken with a grain of salt.  Generally speaking the side effects of vaccine are that the horse gets great immunity to many potentially fatal diseases and you get peace of mind that your horse has protection.

This four year old gelding was presented with swelling and difficulty peeing.  Initially we thought he had been kicked but at sedation a Loonie sized kidney/bladder stone was removed from his urethra, at the end of his penis.  This gelding may have to have his penis amputated, we are treating him conservatively and are still hopeful.

October 4, 2011 update

This four year old gelding recovered very well.  Recently he began exhibiting similar symptoms as before, the result was another huge stone removed from his penis.  His diet and water source have been changed.

  Dr. Domoslai here, I would like to update you on an interesting case.  The bucking horse finally succumbed and on post-mortem had his entire kidneys and bladder were filled with large stones (approximately one gallon of material similar to the scale in a tea kettle)
