This  tonic  purifies  and  builds  up  the  blood,  just  what  is
needed  in  this  particular  condition.
BALDNESS

(Favus)

Cause  :     Due  to  fungi.
Symptoms:  The  first  noticeable  sign  is  the  whitish
appearance  of  the  comb  due  to  gray  spots  about  the  size
of  a  pin  head.  As  the  disease  progresses,  this  condition
spreads  to  other  parts  of  the  body;  the  feathers  look
rough  and  dry  and  break  easily.  The  fowl  grows  weaker,
refuses  to  eat  and  if  not  properly  treated,  dies.
Treatment:  Remove  the  scabs  by  separating  the
feathers  and  using  a  brush.  Apply  Sulphur  Ointment.
Repeat  this  treatment  after  two  or  three  days.  Great
care  must  be  taken  to  prevent  the  fowl  from  chilling  or
taking  cold.
DISEASES    OF    POULTRY  223

BEAK    AND    THROAT    OBSTRUCTION
Cause:     Lodgment  in  the  beak  or  food  canal  of  a  for-
eign substance,  such  as  a  kernel  of  corn,  sunflower  seed,
bone,  etc.
Symptoms:  Fowl  jerks  its  head  suddenly  and  fre-
quently attempts  to  swallow.  If  a  close  examination  is
made  the  foreign  body  can  be  felt  from  the  outside.
Treatment:  For  the  removal  of  such  obstructions,
no  special  treatment  is  needed  further  than  to  use  care
and  avoid  any  injury  to  the  beak  or  throat.  Feed  nutri-
tious food,  as  wheat  bran  mashes  and  vegetables  and  see
that  they  have  a  liberal  quantity  of  good  pure  water  at
all  times.
BLACKHEAD

(Infectious  Entero  Hepatitis  of  Turkeys)
Cause  :  Due  to  a  protozoa  taken  into  the  system  with
the  food  or  drinking  water.  This  parasite  enters  the
caeca  which  becomes  inflamed  and  discolored  and  the
liver  is  enlarged  and  studded  with  yellowish  spots  about
the  size  of  a  pea.
