Dr. Lowder:

I have a 7 month old 1/2 Thoroughbred 1/2 Dutch Warmblood filly that early in Dec. started to get diarrhea. Temperatures dropped to below zero and we first assumed that the diarrhea was due to stress. She has a good winter coat but started shivering during the day and we put a blanket on her. She did not have a loss in appitite and she drinks plenty of water.

Since Dec. she has not grown any in height. She was 12.2 hh and has maintained that for over 2 months. She was loosing weight and has not been able to put it on since then. First thing we did was worm her and her fecal sample shows that she does not have worms. She was on 2 pounds of Stategy and 2 pounds of oats a day. We reduced her grain input and her diarrhea went away.

She had free choice hay and water and ate and drank fine. We switched her to Purina Junior and I added a vitamin & mineral supplement with probiotics to help her utalize her food. We were going to try some good bacteria to see if that would help, but that has been back ordered and we have not been able to try that. Everything seemed to be doing okay in Jan. and we had increased her feed to 3 lbs. a day and she finally stopped having diarrhea.

Then the ferrier came to trim her hooves and found all four of her white lines in her hooves were blood red. There was no bruising in her hooves. I am having blood work done on her and am waiting the results of that. What could be that cause of these problems and what treatment or prevention could be taken?

Thank you! Jennifer Rhyner

Jennifer,

There are a number of reasons for diarrhea and parasites is the most common one I think. I would suggest in additon to doing another fecal the next time she has diarrhea I would also have a culture done. This would tell you if the diarrhea is related to some bacterial infection. What has been the temperature of your filly during all this time? I don’t know what is causing her white line to be blood red? How is she stabled? Does she have to walk on rough concrete or snow? Have your local vet do a physical exam on her in addition to the blood work and see what they find.
Thanks, Dr. Lowder
