A  Fair  Question  and 
a  Reasonable  Answer 
Live  Stock  Matters 
Conducted  By  Prof.  F.  C.  Minkler 
The  question  is  sometimes  asked 
us,  although  less  frequently  as  more 
and  more  De  Laval  Milkers  are  put  in 
use  and  the  wisdom  of  the  De  Laval 
method  is  demonstrated,  why  we  make 
only  single  unit  milkers. 
The  De  Laval  Milker  Unit  is  de¬ 
signed  to  milk  one  cow  at  a  time.  Of 
course  as  many  units  as 
desired  can  be  used  in 
an  installation,  and  all 
of  the  units,  no  matter 
how  many  are  used, 
work  with  exactly  the 
same  uniform  and 
pleasing  action.  This 
method  has  proved  to 
be  the  most  practical  as 
well  as  the  fastest. 
With  a  double  unit  it 
is  necessary  to  arrange 
the  cows  so  that  those  which  require 
about  the  same  length  of  time  to  be 
milked  are  placed  side  by  side,  and  it 
is  practically  impossible  to  do  this 
unless  the  cows  are  constantly  re¬ 
arranged,  which  causes  confusion 
and  delay.  Thus  with  a  double  unit,  if 
the  cows  do  not  milk  out  in  exactly 
the  same  time,  part  of  the  outfit  is 
idle  or  is  left  on  the  cow  too  long. 
Numerous  tests  have  shown  that 
two  single  units  milk  about  one-third 
faster  than  one  double  unit,  and  one 
man  can  handle  two  single  units  faster 
than  one  double  unit.  In  actual  prac¬ 
tice  many  De  Laval  operators  are 
handling  three  units  alone,  and  each 
unit  will  milk  about  ten  average  cows 
or  more  an  hour. 
Another  advantage  of 
the  single  unit,  which 
is  very  important  espe¬ 
cially  in  purebred  test 
work  and  for  which 
many  De  Lavals  are 
now  used,  is  that  it  is 
possible  to  weigh  each 
cow’s  milk  when  indi¬ 
vidual  cow  records  a>-e 
desired. 
Of  course  this  is  only 
one  of  many  features  which  is  making 
the  De  Laval  Milker  so  popular  with 
dairymen  everywhere.  On  more  than 
12,000  farms  the  De  Laval  Milker  is 
saving  time  and  labor,  increasing  the 
production  of  milk,  producing  cleaner 
milk,  and  making  dairying  more 
pleasant  and  profitable.  If  you  are 
milking  ten  or  more  cows  by  hand, 
you  are  paying  for  a  De  Laval. 
Ration  with  Pasture 
What  protein  percentage  is  desirable 
in  a  grain  ration  for  cows  on  pasture? 
New  Jersey.  h.  e.  g. 
It  is  the  prevailing  belief  that  a  24 
per  cent  ration  provides  more  protein 
than  the  average  producing  cow  re¬ 
quires  for  efficient  milk  production 
when  foraging  on  abundant  pasture. 
Other  things  being  equal,  the  addition 
of  cornmeal  to  available  24  per  cent 
mixtures  will  reduce  their  cost  and  not 
materially  reduce  production.  This 
principle,  however,  would  not  apply 
during  the  months  of  July  and  August 
when  the  pastures  are  poor,  but  it 
might  prevail  during  May  and  June 
when  the  grass  is  palatable  and  appe¬ 
tizing.  Since  the  average  dairyman 
feeds  an  insufficient  amount  of  protein, 
care  must  be  taken  to  apply  this  rea¬ 
soning  only  to  conditions  above  re¬ 
ferred  to. 
If  you  desire  a  home-mixed  feed 
carrying  22  per  cent  of  protein  for 
Summer,  the  same  to  be  fed  in  con¬ 
junction  with  blue  grass  and  Alfalfa 
hay,  and  with  green  barley  and  oats  as 
a  forage  crop,  the  following  is  pro¬ 
posed  :  Hominy,  250  lbs. ;  bran,  250 
lbs. ;  gluten  feed,  150  lbs. ;  linseed  meal, 
200  lbs.  This  will  provide  a  22  per  cent 
feed,  and  if  fed  in  conjunction  with 
Alfalfa  hay,  it  is  my  belief  that  it  will 
provide  a  sufficient  amount  of  protein. 
If  your  cows  are  milking  more  than  4U 
lbs.  of  milk  a  day,  the  substitution  of 
100  lbs.  of  gluten  meal  for  the  gluten 
feed  would  provide  the  desired  amount 
of  protein. 
Feed  for  Cows  of  Varying  Production 
I  wish  a  ration  for  Holstein  cows 
that  are  giving  between  30  and  70  lhs. 
of  milk  per  day.  We  have  Alfalfa,  pas¬ 
ture,  and  we  can  get  the  following 
feeds:  Middlings,  $1.25;  cornmeal,  $2; 
ground  oats,  $2 ;  bran,  $2 ;  cottonseed, 
$2.75 ;  gluten  meal,  $2.25 ;  oilmeal. 
West  Virginia.  c.  l.  k. 
I  would  not  include  any  of  the  mid¬ 
dling  in  rations  intended  for  dairy 
cows  during  the  Summer,  even  at  the 
price  quoted,  viz.,  $1.25  per  100 ;  they 
would  not  be  as  desirable  as  corn  or 
bran.  A  combination  consisting  of  250 
lbs.  of  cornmeal.  150  lbs.  ground  oats, 
150  lbs.  bran,  200  lbs.  43  per  cent  cot¬ 
tonseed  meal,  200  lbs.  gluten  meal,  and 
50  lbs.  oilmeal  will  provide  a  combina¬ 
tion  well  suited  to  your  needs. 
For  the  dry  cows  a  simple  combina¬ 
tion  of  40  lbs.  of  cornmeal.  40  lbs. 
ground  oats, -and  20  lbs.  linseed  meal  is 
proposed. 
For  the  cows  that  are  giving  as  low 
as  30  lbs.  and  presumably  have  com¬ 
pleted  the  greater  portion  of  their  lac¬ 
tation  period,  a  mixture  confined  to 
cornmeal,  gluten  feed  and  bran  would 
be  cheaper  than  the  combination  pro¬ 
viding  more  variety.  Five  parts  of 
cornmeal,  three  parts  of  gluten,  and 
two  parts  of  bran  should  compose  the 
mixture. 
For  your  cows  giving  as  much  as  70 
lbs.  of  milk  there  would  be  an  advan¬ 
tage  in  adding  some  linseed  meal  on 
the  side. 
Feed  for  Guernsey  Herd 
Will  you  give  me  a  balanced  ration 
for  my  Guernsey  herd?  I  am  feeding 
all  the  clover  hay  they  want.  How 
much  dried  beet  pulp  should  I  feed? 
New  York.  a.  j.  w. 
It  is  not  necessary  to  feed  beet  pulp 
to  dairy  cows  during  the  Summer,  pro¬ 
vided  they  have  access  to  pasture. 
Beet  pulp  is  a  carbohydrate  feed  and 
is  more  expensive  than  corn  as  a  source 
of  heat  and  energy.  It  is  used  during 
the  Winter  to  provide  both  succulence 
and  mineral  matter,  and  this  substan¬ 
tially  increases  its  feeding  value. 
For  Guernseys  that  have  access  to 
clover  hay  and  pasture  grass,  a  ration 
consisting  of  400  lbs.  of  coi'nmeal  or 
hominy,  100  lbs.  bran,  200  lbs.  gluten 
feed,  200  lbs.  cottonseed,  and  100  lbs. 
oats  is  proposed.  Feed  1  lb.  of  this 
grain  ration  for  each  4  lbs.  of  milk  pro¬ 
duced  per  cow  per  day,  and  Alfalfa 
hay  once  a  day  while  on  pasture.  If 
the  cows  are  yielding  as  much  as  30 
lbs.  of  milk  a  day.  substitute  gluten 
meal  for  the  gluten  feed. 
Trouble  with  Cow 
I  have  a  good  cow  that  was  due  to 
calve  now,  but  on  the  last  day  of 
March  she  dropped  twin  calves,  both 
dead,  and  gives  but  very  little  milk, 
and  that  not  good.  She  seems  to  be  ap¬ 
parently  all  right  and  eats  well.  Is 
there  anything  I  could  give  her  to 
bring  the  milk  back  somewhere  near 
normal?  There  is  no  way  that  I  can 
see  that  she  could  have  hurt  herself 
to  cause  this.  g.  f.  s. 
Ohio. 
The  only  suggestion  that  would  ap¬ 
ply  in  this  method  would  center 
around  the  method  of  feeding  that 
would  enable  this  cow  to  regain  her 
strength  and  vigor.  It  is  possible  that 
the  cow  was  not  properly  fed  previous 
to  calving,  and  that  when  the  twins 
were  born  it  depleted  her  vitality  and 
vigor  to  such  an  extent  that  there  was 
no  response  in  the  way  of  milk  pro¬ 
duction.  In  the  absence  of  complica¬ 
tions  such  as  retention  of  after-birth 
it  is  proposed  that  her  ration  be  re¬ 
stricted  to  equal  parts  of  cornmeal. 
ground  oats,  wheat  bran,  linseed  meal 
and  gluten  feed.  Feed  her  from  7  to  12 
lbs.  of  this  mixture  per  day  and,  in 
addition,  allow  either  good  pasture 
grass  or  plenty  of  clover  or  Alfalfa 
hay.  You  can  scarcely  expect  to  es¬ 
tablish  normal  production  of  milk  until 
normal  conditions  are  restored.  It  fre¬ 
quently  happens  that  cows  fail  to  come 
to  their  milk  promptly  after  delivering 
twins.  Plenty  of  good  feed,  accom¬ 
panied  by  good  care  and  condition  is 
your  only  solution. 
Contagious  Mammitis 
A  year  ago  we  had  several  cows  af¬ 
fected  with  contagious  mammitis,  and 
called  a  veterinary.  He  used  strong  med¬ 
icine  to  dry  them  off,  he  told  me.  I 
thought  they  would  come  to  their  milk 
later,  but  they  did  not.  As  these  same 
cows  have  been  coming  fresh  again,  they 
have  had  practically  no  milk  for  their 
calves  from  the  first.  Some  of  the  teats 
give  a  little  fairly  normal  milk,  others 
thick,  lumpy  fluid,  just  as  they  did  a  year 
ago.  Is  there  any  remedy  for  it  now, 
or  might  something  have  been  done  be¬ 
fore  calving?  e.  s.  m. 
New  York. 
If  the  contagious  mammitis  has  ap¬ 
peared  in  your  dairy  herd  after  the  cows 
have  been  dried  off  and  treated  by  a  vet¬ 
erinarian,  it  seems  to  me  that  the  best 
advice  would  be  to  dispose  of  the  cows 
for  beef,  rather  than  attempt  to  control 
this  disorder.  If  mammitis  gets  a  per¬ 
manent  foothold  in  a  dairy  herd,  there  is 
always  more  or  less  recurrence,  and  if 
the  veterinarian  cannot  suggest  a  means 
of  bringing  the  herd  back  to  normal  pro¬ 
duction  and  the  udders  to  normal  func¬ 
tioning,  certainly  would  not  complicate 
problems  by  attempting  home  remedies. 
Ray  Flanders,  a  small  boy  at  Great 
Bend,  Ivan.,  figured  out  a  new  way  to 
get  20  cents  crow  bounty.  He  told  the 
story  when  he  presented  two  young 
crows  to  County  Clerk  Younkin  the  other 
day  that  he  had  found  two  crows’  eggs, 
and  knowing  that  he  would  get  only  a 
penny  bounty  on  each  egg  and  ten  cents 
on  the  birds,  he  put  the  eggs  under  a  set¬ 
ting  hen  and  she  hatched  out  twp  crows.
