FROM  THE  DIRECTOR

 H. Leon Thacker, DVM, PhD

Good day from ADDL.  The weather has started to cool and fall is in the air. 

Perhaps the major weather related issue for our state this late spring, summer,
and fall has been the lack of rain.  this has brought about shortage of pasture
and hay over much of Indiana.  We have encountered some cattle problems from feeding of alternate feed sources.  The shortage of roughage normally present this time of year and earlier have brought about changes in feeding practices of feeding corn stalks, small grain straw, soybean pummies, raw soybeans and other materials.  caution is to be exercised that these feedstuffs are, first of all, not toxic.

  Two other animal diseases that have been newsworthy in our state this fall have been epizootic hemorrhagic  disease of deer and occasionally cattle and Eastern equine encephalitis of horses.  Epizootic hemorrhagic disease (EHD) is caused by a virus that is related to, but distinctly different from, Bluetongue virus.  It is transmitted by  biting midges; when we get a killing frost or two, the vector of the disease should be markedly reduced and the occurrence of the disease in deer reduced as well.  We have received reports of deaths of large numbers of white tail deer, both captive and wild, in southern Indiana and adjoining states.  At the time of this writing, no vaccine is available to protect susceptible animals.

  Eastern equine encephalitis (EEE) is also caused by a virus, spread is via mosquito vectors.  Most of the reports of EEE affected horses have come from northern Indiana; we have had positive results of horses as far south as Clay County.  Again, as the vector is an insect, killing frost(s) should reduce the means of the disease distribution.  In the instance of EEE however, effective vaccines to protect horses from the disease are available and in routine use among many or most Indiana horse owners.

  The Indiana Department of Natural Resources will again send tissue samples from hunter killed white tail deer to us for chronic wasting disease testing.  In accordance with requirements of the Indiana Board of Animal Health, any captive deer or elk that die of any cause in Indiana are to be tested for CWD.  Over the past six years, we have tested several thousand Indiana deer and elk for CWD.  To date, we have found no positive cases of CWD in   Indiana deer or captive elk.  We expect to test somewhere around twelve or thirteen hundred deer again this year.

  The ADDL has a new fee schedule that took effect October 1, 2007.  We’ve put a great deal of thought and   comparison with other labs into setting the fees.  It is our hope and intention to provide the best diagnostic services for the most reasonable prices we can offer.  Hope you are enjoying the fall weather; it is beautiful in Indiana.
