Discussion on Fly irritation / Allergies ??? | |

Posted on Monday, Feb 23, 2009 - 12:09 pm: From a previous thread, I moved it to a new discussion per DrO's request (hope it's in the right place) My husband recently purchased a mother/daughter set of black mares. They were "blistered" with evidence of previous occurrences by the white scars. We suspected an allergy from either a particular vegetation in their original location or fly bites--or both. The photo below is the 17 yr old mare, while in quarantine, so not the most flattering photo, but conveys the message. The younger mare actually had the worse case of the two in 2008. Both mares have received no preventative care or treatment in the past--ever. Both mares have improved during our winter season, but I have been trying to plan ahead for any necessary treatments this spring/summer. It looks uncomfortable, and in fact, the younger mare had noticeable impairment of movement from the swollen skin, last year. I can't have them uncomfortable. Thanks Jesse for the details on the screw worm spray. I don't mind them running around with painted legs if it helps the problem. I bet it does look funny on a white horse! It was mentioned earlier that perhaps there were whip marks??? I'm not sure which area shows something of that nature. The mares are extremely gentle and easy to work around, so I wouldn't think they were ever "roughed up" with a whip. TX and our area last year had more moisture and flies than normal. The time of the photos, the mares were 2 weeks into quarantine at our place. (We put anything new in isolation--middle of the cattle ranch--for 4-6 weeks. Not the prettiest set-up, but safe, and no other horses within a half mile. We treat everything like it came in from a different country!) The white marks on the hip is a freeze brand (three T's in a tumbling action). The white marks on the one mare's legs are obvious scars from previous "bumps/blisters." These mares came off of a sizable ranch in TX. The smallest parcel was 3500 acres. Their deworming program consisted of an annual dose of Ivermectin. Now, since they were running on such a large area, perhaps that was all that was needed, but ???. They have been with us for 5 months, now. I have dewormed them with SafeGuard (fenbendazole), then recently with EquiMax (Ivermectin and Praziquantel). They are on 80 acres with free-choice hay (and daily alfalfa). They have no signs of the "bumps/blistering" at the moment, but there are also no flies this time of the year. Is this skin issue going to be a constant battle with these mares? Anyone have horses with sensitive skin to give us suggestions? Thanks! |

Posted on Tuesday, Feb 24, 2009 - 6:52 pm: There are several bacterial diseases that may present this way when severe including staph or dermatophillus. The chief difference would be the way the scabs come off. For more on this see the article on dermatophillus. To answer your first question, I do not see any reason this would be a recurring problem as it probably reflects the poor conditions the horses come from.DrO |
