TheDe Laval 
Milker 
At Annapolis Naval Academy Dairy 
Over 250 cows that supply the milk and 
cream for the boys in the Naval Training 
School at Annapolis, are milked by the 
De Laval Milker, which was selected after 
careful tests and comparisons. 
The De Laval Milker is a distinctly different type 
of machine. It is alternating, positive and uniform 
in action—every day the same. It is faster, more 
reliable and more sanitary than any other method 
of milking, and is sold with full knowledge of the 
fact that more is expected of the De Laval than of 
any other milker. 
The sanitary features of the De Laval Milker are 
important in connection with any dairy installation, 
but are worthy of especial attention where the high¬ 
est possible class of product is desired and where 
certified milk is marketed.

Ration for Freshening Heifer; Feeding 
Skim-milk 
1. We have a heifer three years old 
this Spring, due to freshen for the first 
time soon. She has a large udder; it ap¬ 
pears to be inflamed and the hind quar¬ 
ters are hard. What would you do? 
2. What ration would you suggest for 
milkers where mangels were fed, silage 
and hay, either Timothy, mixed hay 
or clover hay? How much mangels 
would you feed? We have buckwheat, 
corn, oats; can grow them any year. 
Gluten we can seldom get. Cottonseed 
and oilmeal can be obtained. Mixed 
feeds are abundant here*, also hominy. 
2. What is the value of skim-milk for 
feeding? j. h.e. 
New York. 
1. It would be well to reduce the grain 
ration that you are feeding the Holstein 
heifer that is about to freshen, feeding 
her largely on such laxative feeds as Al¬ 
falfa hay, wheat, bran, beet pulp or ground 
oats. It may be necessary to eliminate 
practically all of the grain and feed her 
largely on roughage and bran mashes dur¬ 
ing this interval. I should give her a 
purge to relieve any possible congestion. 
A pound of Epsom salts dissolved in a 
quart of warm water, to which has been 
added a pound of molasses diluted in a 
quart, of warm water, should constitute 
the dose. Bathing the udder with hot 
water, to which has been added some salt, 
is also beneficial. 1 should deny the ani¬ 
mal the regular grain ration until all in¬ 
flammation has subsided. 
2. Where you have both silage and 
mangels to supply the succulence for 
milch cows, I should feed 25 lbs. of silage 
and 25 lbs. of mangels per day. If you 
feed mangels alone you will find that 
cows weighing 1.200 or 1,200 lbs. will 
readily consume as much as 70 or SO lbs. 
of the mangels. By all means use the 
clover hay rather than the Timothy hay 
in feeding milch cows. It is more di¬ 
gestible, more palatable and will con¬ 
tribute a great deal more energy to the 
ration. A grain ration consisting of 200 
lbs. of corn, 200 lbs. oats. 200 ]liv. buck¬ 
wheat, 200 lbs. cottonseed. 150 lb*. oil- 
meal and 100 lbs. bran would be satis¬ 
factory. If gluten is cheaper, pound for 
pound, than oilmeal, it could be substi¬ 
tuted in its place. 
2.x Sour skim-milk is quite as useful in 
feeding either pigs or poultry as the 
sweet milk ; in fact, during the Summer 
months, when milk is apt to be sweet one 
day and sour the next, much better results 
follow the practice of souring all of the 
milk and feeding it in Ibis condition. 
When the milk is available it is possible 
to reduce or even eliminate the digester 
tankage in a ration for pigs, and to re¬ 
duce substantially the amount of meat 
meal included in the various mixtures for 
poultry mashes. 
Trouble with Cows 
I have a herd of eight fine Holstein 
; cows. Of the eight cows only one had 
a good calf; five cows lost calves; two 
others had poor calves, which died. A 
neighbor says my barn is too wet and 
damp. In a rainy spell the water runs 
through the gutter, but. cows have plenty 
of straw, and beds are dry. My cows 
are all fat. I feed, per week, 1.100' lbs. 
grain, 600 lbs. corn chop, 400 lbs. buck¬ 
wheat, 100 lbs. wheat bran and all the 
hay and corn fodder they eat. East Win¬ 
ter. instead of ground buckwheat. I fed 
Oats. .r. D. B.

It is evident that your herd' is infected 
with contagious abortion, and this con- 
1 dition. rather than the fact that your 
j barn is a basement barn, ‘and that the 
quarters are damp following a rainstorm, 
is responsible for the failure of the cows 
to produce live calves. When this dis¬ 
ease once gains a foot hold in a herd it is 
not easily stamped out, and the advice of 
a veterinarian is absolutely essential. 
Furthermore, you are in error in assum¬ 
ing that a mere change in bulls will rem¬ 
edy this condition. The best advice that 
I can offer is that you employ a competent 
veterinarian, state to him the facts as 
you have indicated them in this letter, 
and follow his advice and treatment. 
The fact that contagious abortion has in¬ 
fected your herd for some time is rather 
in your favor, for oftentimes it runs its 
course and is believed to be more easily 
controlled during its latter stages. It 
might be good judgment for you to dis¬ 
pose of the cows, since they are in good 
flesh, and after thoroughly disinfecting 
your stable, endeavor to found a new herd 
of healthy animals. Without seeing the 
specimens and knowing more in detail the 
conditions that obtain, it would not be 
prudent to give definite advice in the 
matter. 
A ration consisting of corn chop, ground 
buckwheat ana wheat bran would be 
faulty, inasmuch as it doefts not provide 
protein enough to meet the demands of 
a cow producing milk. You should in¬ 
clude some concentrate, such as gluten 
feed, oilmeal or cottonseed meal, and the 
following proportions would serve: 200 
lbs. corn chon. 200 lbs. buckwheat, 200 
lbs. gluten, 100 lbs. oilmeal, 100 lbs. 
wheat bran.

There are three extra profits 
for every dairyman and 
farmer in the country who

1. One to two quarts of milk more

2. Lower feeding cost. 
3 If you grow grains such as corrf 
and oats just to feed your cows, 
make your third profit by selling 
them and feeding
