world’s closest

One of the great¬ 
est dairy inven¬ 
tions. 
Our scientific experts years ago 
learned that many cream separators 
were utterly unfit for service. They 
found, that a cream waste of 25% 
was the average of separators when 
skimming cold milk. They found 
wastes that were appalling, even 
when skimming at most favorable 
temperatures. 
The cause of these losses they found 
in two tiny butterfat thieves hidden 
away in the ordinary straight discs. 
Thief No. 1—was the narrow, does this, first by means of a 
skimpy spacing between the discs quick “curve in” at the top. 
at the top. This prevented easy This gives extra spacing between 
outflow of the cream. 
Complete clogging often 
resulted when the cream 
was cold, thick and slug¬ 
gish. Thief No. 2 —was 
the low angle of the discs 
at the bottom. Tnis 
failed to give the extra 
separating action so 
necessary for extremely 
close skimming. 
To foil these treacher¬ 
ous thieves our experts 
brought out the now 
famous Curved Disc — 
one of the greatest sci¬ 
entific developments in 
cream separator his¬ 
tory. This Curved Disc 
gives skimming results 
which were hitherto en¬ 
tirely impossible. It 
skims even cold milk 
within 1-300 of 1 per 
cent perfect.

Live Stock Questions 
Answered by Prof. F. C. Minkler 
Ration with Buckwheat 
Would you give me a balanced ration 
for dairy cows so I could use my corn, 
oats, buckwheat, and purchase the bal¬ 
ance to complete it? I am feeding silage. 
Ohio. a. A. c. 
Where you have corn, oats and buck¬ 
wheat to be fed in conjunction with silage 
and some mixed'hay, I would combine a 
ration in the following proportions: Corn, 
400 lbs.; oats, 300 lbs.; buckwheat, 200 
lbs.; gluten, 200 lbs.; cottonseed, 150 
lbs.; oilmeal, 150 lbs.; wheat bran, 200 
lbs. 
Feed approximately 1 lb. of this grain 
mixture for each 3% lbs. of milk pro¬ 
duced per cow per day and, in addition, 
let them have all of the Toughage that 
they will consume with relish. Add 2 per 
cent of salt to this grain ration if it is 
not your practice to keep it before them 
at all times in some convenient recep¬ 
tacle. 
Ration With Silage 
I have on hand at the present time the 
following feeds: Cottonseed, hominy, 
bran, gluten and oilmeal. I wish to make 
up the best ration, testing around 20 per 
cent protein, for Holstein cows. I am 
feeding 35 lbs. of good silage and around 
10 lbs. of fair Alfalfa hay per cow. 
New Jersey. c. l. o. 
A ration consisting of 600 lbs. of hom¬ 
iny, 300 lbs. of oats, 200 lbs. of bran, 150 
lbs. of cottonseed, 200 lbs. of gliaten, 100 
lbs. of oilmeal, would approach the com¬ 
bination you request. This would be rel¬ 
atively concentrated, however, and the 
addition of 200 lbs. of oats and 50 lbs. 
more of cottonseed meal would increase 
its usefulness. This ought to give you 
good results with silage and Alfalfa hay. 
Unless you make it a practice to feed salt 
I would add 2 per cent of salt to these in¬ 
gredients. 
Pigs Do Not Grow 
I have six pigs nine months old, and 
they do not grow. I have been feeding 
middlings, tankage and cornmeal; tank¬ 
age dry, with all the water they could 
drink after eating. w. D. R. 
New York. 
From the description it would seem 
that your pigs must be infested with in¬ 
testinal parasites. When such a condi¬ 
tion prevails the pig has an exaggerated 
appetite, and does not grow or gain 
weight. The hair is dry, coarse and ruf¬ 
fled ; the eyes lack lustre and brightness, 
and the animal shows discomfort and 
irritation. The treatment consists of 
withholding food for 24 hours, dividing 
the herd into groups of 20 animals, and

Bit pigs bring fat profits 
Stop wondering why your pigs 
don’t pick up weight on grain feeds 
alone. Include Dold’s Digester Tank¬ 
age In their feed—a sure fat and bone 
builder—you’ll get them to market 
and bring ready cash quicker. 
When you feed pigs corn, they 
get less than 10% protein. Dold’s 
Digester Tankage gives them 60% 
Protein, Dold’s Digester Meat Meal 
Tankage 46% Protein, the right 
amounts to build bone and flesh. 
Mixed with grain feeds or fed sep¬ 
arately, either In hoppers or slop.

mixing the following worm powder thor¬ 
oughly with the moist food, making sure 
that each hog gets its share of the medi¬ 
cine in the feed at the close of the starva¬ 
tion period : Santonin, 8 grains; Areca 
nut, 2 drams; calomel, 1 grain; sodium 
bicarbonate, 1 dram. This amount is 
sufficient for one hog weighing 100 lbs. 
The dosage should he increased or de¬ 
creased, according to the size of the pig. 
By multiplying this dosage by the num¬ 
ber of pigs that it is desired to treat a 
sufficient quantity may be secured from 
the drug store to treat the entire herd. 
Care should be exercised not to use too 
much food, as it dilutes the medicine. 
This treatment may be repeated in three 
weeks if the worms are not all removed 
by the first administration. 
Perhaps the old remedy of turpentine 
as a vermifuge can be used in case sim¬ 
pler treatments fail. The amount is a 
teaspoonful of turpentine diluted with a 
half-pint of milk, this being suflBeient for 
a pig weighing 50 lbs. Food should be 
denied the animals for 24 or even 36 
hours previous to the administration of 
this unsavory material in order that they 
will consume the desired amount. Para¬ 
sites must be eliminated at any cost, for 
a pig cannot make satisfactory gains if 
he is annoyed by such pests. If your 
pigs are nine months old they ought to he 
finished for market, and you are only 
wasting feed in trying to fatten them 
under the conditions you have described. 
I would not under any circumstances feed 
middlings to hogs of this age, but rather 
rely exclusively upon cornmeal and tank¬ 
age, fed in the proportion of 94 parts of 
corn and six parts of tankage.
