Live  Stock  Questions 
Answered  by  Prof.  F.  C.  Minkler 
Improving  Dairy  Ration 
I  keep  10  cows.  Will  you  give  me  a 
balanced  ration  for  Holstein  and  grade 
cows?  I  am  feeding  20  per  cent  protein, 
1  lb.  to  3*4  lbs.  milk  ;  the  milk  all  goes 
to  butterfat,  but  would  like  ration  for 
more  milk.  For  roughage  am  feeding 
Timothy  hay.  This  is  the  ration  I  am 
feeding  at  present :  300  lbs.  eornmeal, 
200  lbs.  coarse  bran,  150  lbs.  ground  oats, 
150  lbs.  cottonseed  meal.  150  lbs.  linseed 
meal,  150  lbs.  oilmeal,  100  lbs.  gluten.  I 
wish  to  produce  more  milk  and  not  so 
much  butterfat.  G.  N.  H. 
Auba,  N.  Y. 
It  is  well  known  that  the  percentage 
of  butterfat  in  milk  cannot  be  materially 
changed  by  modifying  the  grain  ration. 
The  ability  to  produce  milk  high  or  low 
in  butterfat  is  an  inherited  characteristic. 
However,  normal  milk  is  produced  from 
cows  maintained  in  a  normal  condition, 
and  this  is  why  cows  in  good  flesh  and 
generously  fed  often  produce  milk  su¬ 
perior  in  quality  to  underfed  animals  that 
are  improperly  nourished.  Any  changes 
that  might  appear  to  result  from  modi¬ 
fication  in  the  grain  ration  are  tem¬ 
porary.  The  ration  that  you  are  feeding 
ought  to  prove  a  very  efficient  and  pal¬ 
atable  combination.  Increasing  the 
amount  of  cottonseed  meal  to  200  lbs., 
provided  it  is  43  per  cent  quality  meal, 
would  be  helpful ;  and  doubling  the 
amount  of  gluten  feed  would  bring  your 
combination  up  to  24  per  cent. 
'With  Holsteins  carrying  plenty  of  size 
and  vigor  it  is  believed  that  a  24  per  cent 
ration  will  produce  a  greater  stimulus  for 
milk  production  than  a  20%  combination. 
It  must  be  remembered,  however,  that  an 
abundance  of  roughage  should  accom¬ 
pany  any  ration  carrying  24  per  cent  of 
protein  and  that,  in  addition,  the  cows 
should  be  provided  with  plenty  of  suc¬ 
culence,  or  moistened  beet  pulp.  It  is 
evident,  however,  that  the  feeds  carrying 
the  higher  percentage  of  protein,  espe¬ 
cially  where  the  source  of  protein  is  not 
carefully  guarded,  will  cause  udder 
trouble.  This  condition  often  results 
from  the  use  of  low-grade  mixed  feeds, 
where  the  bulk  of  the  protein  can  be 
traced  to  cottonseed  meal  and  high  pro¬ 
tein  gluten  meal. 
Faulty  Ration 
For  roughage  I  have  had  cornstalks 
and  good  Timothy  and  clover  hay.  Now 
the  stalks  are  gone,  so  will  only  have 
hay.  The  ration  I  have  been  feeding  is 
a  500-lb.  mixture — 100  lbs.  cottonseed 
meal  (36  per  cent  protein),  100  lbs. 
gluten  (23  per  cent)  and  300  lbs.  bran 
(14  per  cent) — which  gives  a  total  of 
20 1/5  per  cent  protein.  Cottonseed 
meal  here  costs  $3 ;  gluten,  $2.70 ;  bran, 
$1.95.  How  would  it  be  to  add  100  lbs. 
eornmeal  to  the  above?  a.  L. 
Columbia  Co.,  N.  Y. 
A  grain  ration  restricted  to  cottonseed 
meal,  gluten  feed  and  wheat  bran  would 
be  faulty,  inasmuch  as  you  have  failed 
to  supply  any  of  your  carbohydrates  from 
their  cheapest  sources,  such  as  hominy 
meal,  eornmeal,  oats  or  buckwheat. 
While  the  price  per  ton  of  bran  is  rela¬ 
tively  low,  the  cost  of  getting  three- 
fifths  of  your  ingredients  from  this 
source  would  be  high  and  well-nigh  pro¬ 
hibitive.  It  is  well  to  remember  that  all 
20  per  cent  feeds  are  not  equally  useful. 
You  might  combine  cottonseed  meal  and 
gluten  and  obtain  a  20  per  cent  protein 
feed  that  would  be  relatively  low  in  cost 
per  unit  of  protein  ;  but  if  this  mixture 
were  fed  to  a  cow  disastrous  results 
would  soon  follow.  It  is  proposed,  there¬ 
fore,  that  you  use  250  lbs.  of  bran,  250 
lbs.  eornmeal  or  hominy,  150  lbs.  cotton¬ 
seed  meal,  150  lbs.  linseed  meal,  200  lbs. 
gluten  feed.  » 
This  will  give  you  a  feed  carrying  the 
same  amount  of  protein  as  you  are  now 
feeding,  and  its  cost  per  unit  of  digestible 
matter  will  be  materially  lower.  Of 
course  bran  is  bulky  and  flaky,  but  the 
restricting  of  your  ration  to  the  three 
ingredients  mentioned  would  not  receive 
the  approval  of  our  most  successful 
dairymen.  Cornmeal  and  hominy  meal 
carry  10  per  cent  protein.  The  addition 
of  cornmeal  alone  to  your  ration  would 
help,  in  which  case  it  would  be  necessary 
to  add  enough  more  gluten  feed  to  bring 
the  combination  to  a  20  per  cent  basis. 
Improved  Dairy  Ration 
Will  you  advise  me  the  kind  of  feeds 
to  mix  with  the  following  that  would 
yield  a  20  or  22  per  cent  protein  dairy 
ration?  Ninety  pounds  ground  oats,  110 
lbs.  ground,  buckwheat,  100  lbs.  bran,  100 
lbs.  cornmeal.  l.  g. 
Thejiddition  of  150  lbs.  of  linseed  meal 
and  150  lbs.  of  43  per  cent  cottonseed 
meal  will  bring  the  amount  of  ingredients 
mentioned  up  to  a  21  per  cent  protein 
basis.  You  can  figure  that  the  ground 
buckwheat  is  about  as  valuable  as  corn¬ 
meal.  If  you  use,  however,  the  buck¬ 
wheat  middlings  rather  than  the  ground 
3uckwheat,  you  will  find  that  the  latter 
will  carry  more  than  double  the  amount 
of  protein  that  the  straight  ground  buck¬ 
wheat  will  yield.  This  combination  ought 
to  give  you  good  results,  provided  the 
bran  is  relatively  free  from  screenings, 
and  the  linseed  meal  and  the  cottonseed 
meal  are  of  the  best  quality.
