-Cow  Testers  Know 
that  DeLaval  Separators 
Skim  the  Cleanest 
Statements  from  over  half  the  cow  testers  employed  by  cow  test¬ 
ing  associations  throughout  the  United  States,  reaching  over  6000 
farms,  give  additional  proof  of  the  superior  skimming  efficiency  of 
De  Laval  Separators. 
Cow  testers  know  best  of  all  what  cream  separators  are  used  most, 
which  skim  cleanest  and  last  longest,  because  they  regularly  test  the 
skim-milk  from  the  separators  owned  by  their  members.  They  say:. 
—“I  find  on  an  average  De  Laval  Separators  skim  cleaner— from  a  trace  to  .04  of 
one  per  cent.  Thirteen  out  of  nineteen  separators  here  are  De  Lavals.”*  (.01  of 
one  per  cent  equals  one  lb.  out  of  every  10,000.) 
—“Out  of  48  separator  users  29  use  De  Lavals.  I’ve  found  them  the  best  skimmers 
for  the  longest  time.’’* 
— “26  members  have  separators,  and  22  are  De  Lavals.  They  give  tho  best 
satisfaction  after  considering  all  points.”* 
— “Do  Laval  Separators  have  no  equal  for  quality  and 
efficiency.  15  out  of  20  are  Do  Lavals.”* 
—“90%  of  tho  separators  used  by  my  members  are  Do 
Lavals.  The  majority  skim  closer  than  .02  of  (me 
per  cent.”* 
— “The  De  Laval  is  a  very  close  skimmer  under 
any  and  all  conditions.  95%  of  the  separators 
here  are  De  Lavals.”* 
— “I  have  25members  and  13  use  De  Lavals.  I  have 
not  had  one  test  below  .05  of  one  per  cent.”* 
♦Authorities  for  these  statements  from  cow 
testers,  together  with  many  others  equally  good, 
are  contained  in  a  booklet  entitled  “Cow  Test¬ 
ers— What  They  Do  and  What  They  Say  About 
De  Laval  Cream  Separators  and  Milkers.”

Answered  by  Prof.  F.  C.  Minkier 
Trouble  With  Silage 
We  put  up  a  new  stave  silo  last  Fall. 
Now  we  have  about  six  feet  of  silage  in 
the  bottom  of  the  sijo  and  it  is  beginning 
to  heat  and  spoil.  Can  you  give  us  a 
remedy  for  this  and  tell  the  cause  of  it? 
The  fodder  had  been  frozen  and  was  quite 
dry  when  it  was  put  in  the  silo.  The 
silage  was  kept  level  in  the  silo  and  was 
tramped  while  filling.  We  would  like  to 
know  about  the  inoculation  of  silage  and 
if  we  can  make  the  lactic  acid  bacteria  on 
the  farm  ourselves,  and,  if  so,  how? 
Madison  Co.,  N.  Y.  w.  L.  M. 
It  is  not  necessary  to  inoculate  silage 
that  is  produced  from  green  corn.  The 
culture  method  of  inoculation  has  been 
resorted  to  with  good  results  where  the 
dried  or  shredded  fodder  has  been  put  into 
the  silo  in  conjunction  with  water.  It  is 
doubtful  whether  homemade  cultures 
could  be  depended  upon  to  establish  fer¬ 
mentation.  Undoubtedly  the  most  satis¬ 
factory  results  would  accompany  the  use 
of  commercial  products.  The  mere  addi¬ 
tion  of  water  to  corn  that  has  dried  un¬ 
duly  previous  to  being  run  through  the 
silage  cutter  is  all  that  is  necessary  to  es¬ 
tablish  proper  fermentation. 
As  to  correcting  the  acidity  of  the 
silage  now  on  hand,  I  know  of  nothing 
that  can  be  done.  Always  in  the  bottom 
of  silos  that  are  not  drained  one  encoun¬ 
ters  silage  that  is  more  or  less  toxic  and 
the  material  is  unpalatable.  It  must  be 
fed  in  small  quantities  and.  if  combined 
with  beet  pulp,  usually  it  is  possible  to 
get  rid  of  the  mass  before  grass  is  avail¬ 
able.  No  doubt  the  fact  that  the  corn 
was  frosted  before  it  was  ensiled  is  re¬ 
sponsible  for  your  trouble  ;  but  I  do  not 
share  the  belief  that  the  addition  of  cul¬ 
ture  bacteria  would  in  any  manner  solve 
your  problem.  Exercise  more  care  an¬ 
other  year  in  the  matter  of  cutting  the 
corn  and  in  the  selection  of  a  variety 
that  will  mature  before  frost  arrives. 
Increasing  Milk  Flow 
We  have  a  grade  Jersey  and  Guernsey 
cow  from  which  we  think  we  do  not  get 
the  milk  we  ought  to.  We  feed  hay,  corn¬ 
stalks  and  a  mixture  composed  of  300  lbs. 
bran,  100  lbs.  gluten.  50  lbs.  ground  oats, 
25  lbs.  oilmeal,  25  lbs.  cottonseed  meal, 
and  salt  three  times  a  week.  Though  the 
cow  has  a  clean  and  airy  stall,  and  is 
milked  regularly  twice  daily,  we  get  only 
about  four  quarts  daily.  She  is  not  due 
to  freshen  until  July.  Can  you  help  us? 
Pennsylvania.  o.  j.  o. 
The  ration  that  you  have  proposed  car¬ 
ries  20  per  cent  of  protein,  and  there  is 
no  reason  why  a  cow  of  average  ability 
should  not  produce  an  abundance  of  milk 
when  fed  as  you  have  suggested.  More 
variety  and  the  addition  of  some  succu¬ 
lence  might  result  in  increasing  the  flow 
of  milk,  but  if  the  cow  is  due  to  freshen 
early  in  April  the  chances  are  that  her 
relatively  low  daily  production  is  due  to 
the  fact,  that  she  is  approaching  the  end 
of  her  lactation  period.  Some  cows  go 
drv  three  months  out  of  the  12  ;  others 
give  milk  right  up  to  the  time  of  calving. 
It  is  believed  by  dairymen  that  an  eight 
weeks’  rest  period  approaches  the  ideal. 
It  is  always  a  difficult  matter  to  increase 
the.  flow  of  milk  during  the  end  of  a  lac¬ 
tation  .period.  However,  by  increasing 
the  amount  of  grain  and  using  the  fol¬ 
lowing  mixture  it  is  possible  that  the  milk 
flow  will  be  inceased :  50  lbs.  of  corn, 
125  lbs.  bran.  100  lbs.  gluten  feed,  50  lbs. 
oats,  75  lbs.  linseed  meal,  50  lbs.  cotton¬ 
seed  meal,  50  lbs.  bran.  This  will  give 
you  a  22  per  cent  protein  combination, 
and  it  may  stimulate  the  mammary  sys¬ 
tem. 
Feeding  Young  Stock 
What  is  the  proper  ration  for  Guernsey 
heifer  to  freshen  shortly,  first  calf?  This 
heifer  is  2*4  years  old,  in  good  condition. 
I  have  mixed  hay  and  buy  my  other 
feed.  Jersey  heifer,  four  months  old  ;  I 
want  to  put  her  on  a  grain  ration.  Should 
I  feed  beet  pulp  to  the  Guernsey? 
New  York.  g.  w.  s. 
For  the  Guernsey  heifer  that  is  to 
freshen  shortly  it  is  proposed  that,  the 
following  mixture  of  feed  be  utilized  and 
fed  following  parturition  :  25  lbs.  linseed 
meal,  20  lbs.  oats.  20  lbs.  cornmeal,  20 
lbs.  gluten  feed,  15  lbs.  bran.  Until  the 
heifer  freshens  a  simple  ration  consisting 
of  equal  parts  of  oats  and  bran,  to  which 
has  been  added  10  per  cent  of  linseed 
meal,  should  be  fed.  This,  in  conjunction 
with  a  quality  roughage  such  as  Alfalfa 
or  clover  hay  will  give  you  good  results. 
For  the  four-months-old  calf  a  mixture 
consisting  of  25  lbs.  middlings,  35  lbs. 
oats,  15  lbs.  linseed  meal.  25  lbs.  bran,  is 
proposed.  Feed  as  much  of  this  mixture 
as  the  calf  will  clean  up  with  relish  each 
day.  If  skim-milk  is  available,  feed  as 
much  as  20  lbs.  per  day  in  two  feedings, 
night  and  morning.  As  soon  as  the  calf 
will  nibble  away  at  clover  or  Alfalfa  hay 
this  should  b  •  provided. 
It  will  nrt  be  necessary  to  feed  beet 
pulp  to  the  Guernsey  heifer  after  she  is 
turned  out  to  pasture.  Until  grass  is 
available,  however,  beet  pulp  should  be 
moistened  12  hours  before  feeding  and 
used  to  provide  succulence.
