﻿88 
  Seventh 
  Annual 
  Report 
  of 
  the 
  

  

  At 
  this 
  "writing 
  the 
  disease 
  would 
  seem 
  to 
  be 
  under 
  control, 
  as 
  

   no 
  late 
  cases 
  have 
  been 
  reported 
  from 
  that 
  quarter. 
  The 
  experi- 
  

   ment 
  of 
  Professor 
  Moore 
  is 
  of 
  particular 
  value 
  in 
  showing 
  that 
  

   rabies 
  actually 
  exists. 
  

  

  In 
  every 
  instance 
  where 
  black 
  quarter 
  was 
  found 
  our 
  veterin- 
  

   arians 
  vaccinated 
  the 
  healthy 
  stock 
  with 
  black-leg 
  vaccine 
  and 
  

   not 
  one 
  case 
  of 
  death 
  was 
  reported 
  as 
  the 
  result 
  of 
  vaccination, 
  

   nor 
  did 
  it 
  develop 
  the 
  disease 
  in 
  any 
  of 
  the 
  animals. 
  AVe 
  have 
  

   not 
  had 
  a 
  favorable 
  opportunity 
  to 
  experiment 
  with 
  a 
  modified 
  

   form 
  of 
  the 
  Tussant 
  method 
  of 
  dealing 
  with 
  this 
  disease, 
  owing 
  

   to 
  difficulty 
  of 
  procuring 
  blood 
  at 
  proper 
  time. 
  

  

  The 
  disease 
  known 
  as 
  infectious 
  aboiiion 
  in 
  cattle 
  has 
  come 
  to 
  

   my 
  attention 
  in 
  several 
  localities, 
  although 
  no 
  investigation 
  has 
  

   been 
  made 
  concerning 
  its 
  cause 
  or 
  prevention. 
  It 
  has 
  been 
  reported 
  

   by 
  a 
  number 
  of 
  cattle 
  owners 
  that 
  this 
  affection 
  was 
  a 
  very 
  serious 
  

   hindrance 
  to 
  the 
  dairy 
  and 
  cattle-breeding 
  industries. 
  Wlien 
  this 
  

   trouble 
  begins 
  in 
  a 
  herd, 
  it 
  usually 
  affects 
  nearly 
  all 
  of 
  the 
  coavs; 
  

   the 
  loss 
  of 
  calves 
  frequently 
  being 
  as 
  high 
  as 
  90 
  per 
  cent. 
  After 
  

   the 
  first 
  abortion 
  the 
  cow 
  does 
  not 
  readily 
  conceive 
  again, 
  and. 
  if 
  

   she 
  does, 
  abortion 
  is 
  again 
  liable 
  to 
  follow, 
  after 
  which 
  the 
  animal 
  

   may 
  recover. 
  However, 
  the 
  loss 
  is 
  so 
  heavy 
  that 
  usually 
  th'e 
  abort- 
  

   ing 
  animals 
  are 
  put 
  into 
  beef, 
  which 
  is 
  a 
  great 
  sacrifice 
  in 
  case 
  of 
  

   blooded 
  stock 
  or 
  choice 
  dairy 
  cows. 
  The 
  spread 
  of 
  the 
  disease 
  

   ican 
  sometimes 
  be 
  checked 
  by 
  means 
  of 
  thorough 
  disinfection. 
  This 
  

   trouble 
  is 
  so 
  serious 
  and 
  so 
  widely 
  distributed 
  in 
  the 
  dairy 
  

   districts 
  that 
  it 
  seems 
  desirable 
  to 
  call 
  special 
  attention 
  to 
  it, 
  and 
  

   to 
  suggest, 
  on 
  account 
  of 
  its 
  gTeat 
  economic 
  importance 
  to 
  cattle 
  

   raisers, 
  that 
  a 
  thorough 
  inquiry 
  should 
  be 
  made 
  into 
  its 
  nature 
  and 
  

   means 
  of 
  prevention. 
  

  

  Of 
  the 
  other 
  diseases 
  mentioned 
  as 
  existing 
  in 
  this 
  State 
  during 
  

   the 
  past 
  year, 
  there 
  were 
  a 
  few 
  isolated 
  cases 
  which 
  were 
  easily 
  

   subdued. 
  There 
  have 
  been 
  a 
  number 
  of 
  diseases 
  reported 
  to 
  the 
  

   Departmtent 
  believed 
  to 
  be 
  contagious 
  in 
  their 
  nature, 
  J^ut 
  further 
  

   investigation 
  is 
  necessary 
  before 
  I 
  can 
  undertake 
  to 
  make 
  definite 
  

   statements 
  concerning 
  them.
