Milker 
De Laval Udder Pulsator—the 
only pulsator close to udder 
Among the many new and exclusive 
advantages in the construction of the 
De Laval Milker, particular attention is 
called to the Udder Pulsator and the 
teat-cups. 
The Udder Pulsator is located within a few 
inches of the cow's udder, which insures positive 
and snappy action in the teat-cups. The action is 
uniform, gentle and pleasing to the cow. The 
only moving part in the pulsator is a small, plain 
piston which requires no oiling, adjusting or re¬ 
pairing. 
The weight of the teat cups and Udder Pul¬ 
sator has been carefully and scientifically worked 
out to produce the best and most satisfactory 
results. The De Laval teat-cups are self-adjust¬ 
ing and made in one size only, which fits all teats. 
The construction is so simple that they can he 
easily taken apart, cleaned and put together. No 
metal touches the teats, and the only rubber part 
is the liner, a straight piece of pure rubber tubing. 
Every other part of the De Laval Milker is 
equally simple, practical and efficient. 
The name “De Laval” is insurance of satis¬ 
faction.

Feeding Cow on Pasture 
Will you give a formula of food for my 
Cow? I can buy wheat bran and mid¬ 
dlings. corn meal, ground oats, oilmeal and 
cottonseed meal. e. e. w. 
Michigan. 
A ration well suited for feeding dairy 
cows where they have access to pasture 
grass would consist of the following: 200 
lbs. cornmeal, 150 lbs. gluten, 50 lbs. 
ground oats. Tf the cows are carrying 
considerable flesh the oats might be 
eliminated and 100 lbs. of cottonseed meal 
substituted. Where the grass is abundant, 
and where one has an abundance of corn- 
meal it is not necessary to feed very much 
protein. In fact, cornmeal alone has 
been known to give very good results 
when fed to dairy cows pasturing on an 
area producing clover or Alfalfa. 
A Good Ration 
I wish your opinion of the following 
ration which T have been feeding to four 
Guernsey cows. One is a small lieifer, 
recently calved. One will calve first 
week in .Tunc, the other in September. 
These cows give about the same amount 
of milk—afloat seven or eight pounds— 
per day. They have had clover bay and 
chopped stalks three times a day and 
grain t wice a day. The following is what 
I feed: 200 lbs. ground oats. 100 lbs. 
bran. 100 lbs. cornmeal. 50 lbs. cotton¬ 
seed meal. 100 lbs. gluten. What quan¬ 
tity should they be fed? j. M. c. 
Connecticut. 
A ration consisting of 200 lbs. ground 
oats. 100 lbs. bran. 100 lbs. cornmeal. 50 
lbs. cottonseed meal. KM) lbs. gluten is 
have had none since increasing the bran 
in ration. Would like to feed more corn¬ 
meal if there is no danger, as it is the 
second cheapest feed we have. T. i.. n.

An excess of any concentrated material 
is more likely to produce congestion of 
the udder than a mixture more bulky in 
nature and consisting of a greater variety. 
Concentrated protein carriers, such as 
gluten and cottonseed meal, are more 
troublesome than cornmeal. Surely the 
limited amount of this product, that you 
have in your ration would not be injuri¬ 
ous. It. is possible that wheu the silage 
was exhausted you increased the amount 
of grain, hoping that the milk flow might 
remain constant, and as a result may have 
fed an excessive amount of concentrates. 
Some such product as beet pulp or oven 
buckwheat bran would lighten your ra¬ 
tion. and. no doubt, do away with any 
further trouble. 
Rather than double the amount of bran, 
I would suggest the increasing of the 
amount of cornmeal, and. if possible, it 
would be well to grind the corn, cob and 
all. in order to make the combination 
more bulky. Tt is certain that cornmeal 
is more economical than bran as a source 
of digestible nutrients. As the season 
advances and the cows have access to 
pasture. T would surely increase the 
amount of corn and reduce very materially 
the amount of concentrates. 
Corn Spoiled in Crib

Guernsey Cow Mabel of Tarbell Farms, 50758, owned by If. II. Buckley of Oteego 
County. N. Y. She has recently completed an official record of 13,110.9 lbs. of 
milk. 704.97 lbs. of butterfat. She was born in October, 1914. Her sire, George 
Washington of Maple Farms 20303, lias five advanced register daughters. 
well balanced and ought to be well 
adapted for feeding milcli cows. If the 
cow happens to be thin in flesh then the 
amount of cornmeal should be doubled. 
So far as quantity is concerned, they 
should be fed in proportion to their pro¬ 
duction. The safest rule perhaps to fol¬ 
low is to feed one pound of grain for each 
314 or four pounds of milk produced per 
day. A cow yielding 29 pounds of 4 per 
cent milk should be fed according to this 
rule approximately seven pounds of grain 
per day. Tn addition let her have all of 
the cornstalks and mixed hay that she 
will clean up with relish. 
A cow that is dry should likewise bo 
fed some grain. The amount should be 
determined by the degree of flesh or the 
condition that she presents. It is well 
to have her freshen in good condition. 
There should be an abundance of flesh 
that she may go through calving nor¬ 
mally and yield the greatest amount of 
milk when her lactation begins. Equal 
parts of corn, gluten and bran make an 
excellent combination for dry cows. II it 
is possible the cows should be pastured 
during the Summer months, for if will 
•/five them needed exercise and. provided 
the picking is luxuriant:, they will re¬ 
spond by giving an increased amount, of 
milk during the coming Winter months. 
Cornmeal in Cow Ration 
1 have been feeding the following mix¬ 
ture to my Holstein cows: 190 lbs. cot¬ 
tonseed. 199 lbs. cornmeal. 200 lbs. glu¬ 
ten. 2(H) lbs. wheat bran. 100 lbs. ground 
oats. 
They have all tlu* mixed hay they will 
•lean up and silage ,up to tt couple of 
weeks ago. Some time ago the supply of 
ground oats ran out, and we had a little 
odder trouble. 1 have since doubled tin* 
bran, so am now feeding 100 lbs. cotton¬ 
seed. 100 lbs. cornmeal. 200 lbs. gluten. 
109 lbs. bran. Will cornmeal cause udder 
trouble? We were told that it would, but 
between the boards. Iu the Winter the 
door blew off and the snow covered the 
corn, and now it is mildewed and not fit 
for the stock. I say the snow did it. 
The stockman says the snow does not 
hurt the corn. Who is right? 2. How 
many bushels of oats shall I sow per acre 
for cows if cut in the milk? Will these 
oats be all right to be put on sod plowed 
last Fall? d. C. S 
Connecticut. 
1. Assuming that the corn was all ma¬ 
tured when it was put into the crib, it is 
possible that the damage was caused by 
the snow beating into the door and moist¬ 
ening the corn, finally causing fermenta¬ 
tion in the Spring. On the other hand, 
a cement floor in the corncrib is not the 
ideal arrangement, for it prevents free 
circulation of the air, and, even though 
boards were placed on top of the cement 
to take care id' the accumulated moisture, 
it would not. prevent immature corn from 
mildewing and spoiling. Last year was 
an unusual year for corn storage, as so 
much of the grain was put away imma¬ 
ture. it would be impossible to settle 
this dispute unless one were advised of 
the condition of the maturity of tlit* corn 
when if was cribbed. I am inclined t« 
believe, however, that immaturity and a 
tight-bottom cement crib bad more to do 
with the moldy condition than the snow 
that might have blown through a small 
open doorway. 
2. I fake it. that you desire information 
suggesting a seed mixture for a soiling 
crop intended for dairy cows. Equal 
parts of Canada field peas and oats, by 
measure, seeded at the rate of three bush¬ 
els per acre, will give you the best results. 
The best results would not follow the 
seeding of oats on freshly broken sod: 
but where it was plowed in the Fall, and 
where care was exercised iu working it 
over well in the Spring, an acre might 
be seeded with oats, provided they were 
put in early, and mixed with Canada field 
peas, as lias been suggested.
