“I took your statement regard* 
ing the performance of a 
De Laval Milker with 
a grain of salt ”— 
said Lewis A. Toan, of Perry, N. Y., a breeder of purebred Guernseys, 
who goes on to say: 
“ We use the De Laval Milker and I am so well pleased with it and 
your De Laval Service that I want to express my appreciation. We were 
4 up against it’ for help before we put in the De Laval Milker, with a 
stable of 24 cows and part of them on test milking three times a day. 
I must say frankly that I took your statement regarding the performance 
of the De Laval with a grain of salt. 
“I am really surprised that the De Laval Milker can 
milk so fast and so clean. It is easy for me to handle 
the two single units, strip, carry and weigh the milk 
for our herd. Our bacteria count, by the way, is low— 
seldom over 10,000. 
“We appreciate the Milker, and another thing — the De Laval Service, 
which you apparently forgot to emphasize when I purchased our machine. 
That in itself is worth a lot to a beginner. If anyone wants my opinion 
of the Milker, tell him to call me up.” 
There are thousands of other De Laval Users who feel just the same 
way. If you are milking 10 or more cows, a De Laval Milker will soon 
pay for itself in saving time and in extra milk of better quality produced 
through its use. Sold on easy terms.

Ration With Brewery 
Grains 
At present I am feeding a 14-quart 
pail of wet brewery grain morning and 
night, with one pound of dry grain for 
every three pounds of milk, consisting of 
800 lbs. gluten, 400 lbs. meal, 400 lbs. 
brown middling, 400 lbs. ground oats, 
and 25 lbs. of salt, and all the hay they 
can clean up twice a day. Hay is of 
poor quality. Do I have a balanced ra¬ 
tion? If not will you suggest one? 
Broome Co., N. Y. l. b. 
While the combination of ingredients 
such as you have indicated constitute 
what one might term a fairly well bal¬ 
anced ration, it is faulty, inasmuch as 
you have depended upon the gluten feed 
to supply all of your protein and that 
you have used middlings rather than 
bran to provide your cereal protein. 
As I figure it, there would be 352 lbs. 
of crude protein in a ton of this mixture, 
which is an equivalent of a 17 per cent 
protein feed. Since you have wet brewery 
grains to feed in addition to this, morn¬ 
ing and night, it will be possible for you 
to simplify the mixture somewhat and if 
you have an abundance of wet brewery 
grains it is unnecessary to feed anything 
in conjunction with them with the ex¬ 
ception of cornmeal. For many years, 
the most desirable and efficient ration 
that was fed to a herd of dairy cows by 
a successful dairyman was limited en¬ 
tirely to a mixture of cornmeal and wet 
brewers’ grain. The brewers’ grains 
provided the protein, they are succulent 
and especially palatable, and when sup¬ 
plemented by cornmeal, are nutritious 
and satisfying. 
But the days of brewery grains are 
over. Vinegar grains and malt sprouts 
have attempted to follow along the 
brewery grains’ trail, but they have 
fallen down miserably in their attempt to 
subsitiute for this most excellent succu¬ 
lent feed. I should feel, therefore, that 
it would be to your advantage to modify 
your grain mixture so that the protein 
would trace to other sources, and the fol¬ 
lowing combination, assuming that the 
wet brewery grains are not available, is 
proposed: 500 lbs. gluten feed, 300 lbs. 
cottonseed meal, 200 lbs. linseed meal, 
400 lbs. cornmeal, 300 lbs. bran, 300 lbs. 
ground oats. 
If the wet brewery grains are avail¬ 
able, then the oats and the linseed meal 
and the bulk of the bran can be released 
and the amount of cornmeal substantially 
increased. It goes without saying, that 
accompanying a mixture of this char¬ 
acter one should use a legume hay of 
good quality, for actually the roughage 
quite generally determines the success or 
failure of milk production enterprise. 
One can use a fairly simple grain mix¬ 
ture provided he has Alfalfa or clover 
hay, but in the absence of a roughage of 
quality and when it becomes necessary 
to use straw or roughages of this char¬ 
acter, then it is indeed difficult to combine 
a grain mixture that will be satisfactory 
and that will enable • the farmer to ob¬ 
tain a new dollar for an old one in his 
daily milking activities. 
Feeding Holstein Herd 
I have charge of a herd of purebred 
Holstein cattle, and ship milk. I have 
the cattle on a good pasture of blue grass 
and orchard grass, and I would like to 
have a good ration, using homegrown corn, 
oats and barley ; the rest w r e have to buy. 
We have good Alfalfa hay, but we have 
not been feeding any hay since on pas¬ 
ture. s. A. z. 
I Loicy that the abundant pasture that 
you referred to has now lost some of its 
succulence. Hence I am suggesting a 
combination of ingredients that will carry 
about 21 per cent of protein. Ordinarily 
this is more of this constituent than is 
necessary to feed during the Summer 
months, especially if the pastures are at¬ 
tractive, so if I have misjudged the con¬ 
ditions you will reduce the oilmeal to 100 
lbs. and increase the cornmeal in like 
amount. 
In case a cow will yield as much as 40 
lbs. of milk per day, then the 21 per cent 
protein feed will serve its purpose even 
during this season of the year. For ani¬ 
mals yielding less than this amount of 
produce, let us say 25 lb.s of milk a day, 
a decreased amount of grain as well as a 
reduced amount of protein will bring 
about the desired conditions. The ration 
which I should propose is as follows 
Ground barley, 150 lbs.; cottonseed 
meal, 43 per cent, 200 lbs.; oilmeal, 150 
lbs. ; cornmeal, 350 lbs.; ground oats, 150 
lbs. 
Feed 1 lb. of this combination in two 
equal feeds morning and night for every 
4 lbs. of milk that each cow is producing 
per day. Make sure to give the cows that 
are yielding the greatest amount of milk, 
irrespective of their condition, a propor¬ 
tionate advantage in the amount of grain 
distributed for nothing is more disastrous 
in the feeding of a dairy herd than to at¬ 
tempt to feed all the same amount of 
grain, irrespective of the amount of milk 
they are producing. If your pastures lose 
their attractiveness, it may be necessary 
to feed some hay in conjunction with 
grain and also some nicely cured Alfalfa, 
which is classified in the front rank as 
roughage for dairy cattle. As you know, 
it is advisable to feed 1 or 2 per cent of 
salt, either as a component part of the 
grain ration, or it may be supplemented 
with bonemeal or ground limestone, used 
as a licking mixture. We have repeatedly 
emphasized the fact that minerals are 
more completely assimilated when con¬ 
sumed in conjunction with green grass 
during the Summer than when they are 
fed to supplement a feed and fed during 
the Winter in conjunction with dry feed. 
Heavy Shrink in Milk 
We have 12 heavy milkers which have 
given us 140 quarts of milk, and in the 
Past week they have suddenly dropped to 
40 quarts. We have been feeding them 
on a mixture of milk feed, cornmeal, 
ground oats, gluten and bran, and regu¬ 
lar pasture. l. l. e. 
The reason why your dairy herd has re¬ 
duced its flow of milk from 140 quarts to 
approximately 100 quarts within a few 
days is that the ration that you have been 
using is deficient in protein. Perhaps 
during the period when grass was abun¬ 
dant and particularly palatable the cows 
were able to overcome this deficiency. 
However, when the succulence disap¬ 
peared and there was evidently a lack of 
distinctive nutriment, there was only one 
thing for the cows to do, and that was to 
reduce amount of milk. 
I do not know just what is identified by 
the terms “milk feed,” but a combination 
of cornmeal, ground oats, gluten and bran 
would still be deficient in milk-making 
constituents. It is inadvisable to permit 
gluten feed to> supply all of the protein 
necessary to bringing a combination of 
this class into balance. Eespecially is 
this true during the Summer, when an¬ 
noyance from flies and irritation from the 
results of hot weather are prevalent. So, 
in order to meet this condition and to use 
the same ingredients that you have on 
hand, and combine, at the same time, a 
mixture that will increase the production 
of milk, it is proposed that you utilize the 
following mixture: 300 lbs. of cornmeal, 
100 lbs. of gluten feed, 150 lbs. of wiieat 
bran, 200 lbs. of gluten meal, 100 lbs. of 
linseed meal, 100 lbs. of ground oats. 
In case the basic ingredients enumerat¬ 
ed are of standard analysis, this com¬ 
bination will yield between 21 and 22 per 
cent crude protein. This feed, in com¬ 
bination with pasture and supplemented 
perhaps with some Alfalfa, clover or hay, 
will bring your cows back to their usual 
flow of milk. Remember, however, that it 
is not an easy matter to bring cows back 
to their usual flow of milk, especially if 
the ration that has been fed for some time 
is deficient in vital constituents. It may 
be necessary to feed and increase the 
amount of grain temporarily in order to 
stimulate the flow of milk and thus assure 
the animal system that there is sufficient 
digestive nutriment to maintain her body 
and make it possible for her to secrete 
the additional amount of milk. As to the 
amount to feed, use 1 lb. of this grain
