Only the 
‘Squeal” Is Wasted 
We are proud that modern methods 
utilize every part of the pig but the 
,, squeal. ,, 
Why not be proud that modern 
science allows no edible food or feed 
products to be wasted. 
Ready mixed feeds are composed 
largely of by-products. These are 
intelligently and correctly milled and 
blended to give better results than 
the grains or materials from which 
they are derived. 
None are suitable for human con¬ 
sumption, in fact, not many years ago 
many of them were thrown away as 
worthless. All materials having feed¬ 
ing value should be conserved for 
economic use. 
A mixed feed is a standardized prod¬ 
uct. It has its trade mark and is 
sold under its trade name and guar¬ 
anteed analysis. It can no more be 
adulterated than an automobile. 
You buy it like an automobile, solely 
on results—and satisfaction—if it 
doesn’t suit, you quit it. 
The Federal and State feed inspection 
laws do not allow the use of any 
injurious or worthless materials, or 
anything to be used secretly or 
fraudulently. 
You are protected by this compliance 
with the laws of every state, and the 
Federal statutes.

According to the Wolff Lehmann feed¬ 
ing standards, a 1,000-lb. cow yielding 
2714 lbs. of milk per day requires 32 lbs. 
of dry matter, 3.3 lbs. of crude protein, 
13 lbs. of carbohydrates and O.S lb. of 
fats, with a nutritive ratio of 1:4:5. For 
maintenance alone a 1,000-lb. cow re¬ 
quires 0.7 lb. of digestible crude protein 
and 7.925 lb. of total digestible nutrients. 
Profitable Milk Production 
W'itli an abundance of good silage with 
ears in it, and Alfalfa meal, both figured 
as a home-grown roughage without any 
cash outlay, will you give me a ration for 
the most economical production of milk 
from Guernseys weighing 900 lbs.? I 
know that Alfalfa hay is probably just as 
good as Alfalfa meal, but we are in a 
peculiar position regarding having a sup¬ 
ply of Alfalfa meal. Would, for instance. 
SO per cent milk production, based mainly 
on these two feeds, be more profitable 
than 100 per cent production with the ad¬ 
dition of concentrates? 11 . j. f. 
Rhode Islaud. 
You have raised a very interesting 
question and one that has been discussed 
frequently through the columns of this 
journal. It is possible to produce milk 
economically through the exclusive use of 
silage and Alfalfa hay. Naturally one 
limits the production l>y omitting con¬ 
centrated feeds, and relying exclusively 
upon the two bulky substances, for it is 
quite impossible for a dairy cow to eat 
enough of these two substances to operate 
her milk-making machinery to the best 
advantage. I have often made the state¬ 
ment that there are cows that would 
yield 40 lbs. of milk at a profit and 50 
llis. of milk at a loss, the difference, of 
Course, being determined by the cost of the 
e$tra 10 lbs. of milk, not only from the 
standpoint of feed cost alone, but taking 
rather the wear and tear resulting from 
forcing a dairy cow past her natural 
stage of production. T 11 many cases the 
feeding of relatively large amounts of 
grain have divorced production from re¬ 
production : in other words, one does ob¬ 
tain rather abnormal yields of milk, but 
he often does this at the expense of en¬ 
ergy, vitality and breeding propensities, 
and oftentimes depletes the value of the 
machine. 
Where you have Alfalfa meal, a gen¬ 
erous amount of protein would be pro¬ 
vided. as it is possible to induce a cow 
to eat more Alfalfa meal than she would 
consume of Alfalfa hay. A 1.000-lb. cow 
would probably eat 40 lbs. of silage and 
*25 lbs. of Alfalfa meal. This would pro¬ 
vide considerably more than a mainte¬ 
nance ration, and. depending upon her 
stage of lactation, would enable her to 
yield considerable milk. Experiments 
that have been carefully conducted lead 
us to believe that prudence justifies the 
feeding of some grain even with silage 
and Alfalfa meal, if oue insists upon es¬ 
tablishing 100 per cent efficiency. As a 
matter of fact, actual trial under your 
own conditions would lie the only safe 
'guide in determining whether it was 
more profitable to feed silage and Alfalfa 
meal and obtain SO per cent production, 
rather than buy expensive concentrates 
that might increase production to 100 per 
cent normal. The only grains that I 
would add under such conditions would 
be corumeal and gluten meal, mixed about 
50-50. 
Ration for Grade Holsteins 
Will you give me a balanced ration for 
a bunch of Holstein grade cows? I have 
uo roughage for them, only daisy and 
Timothy hay: cannot get beet pulp here. 
New York. 1 .. n. 1 . 
We are all agreed that daisy and Tim¬ 
othy hay is ill suited for feeding dairy 
cows. You have failed to mention any of 
the feeding stuffs that you have <>n hand, 
or that may have been produced on the 
farm, and it is not au easy problem to 
build a satisfactory ration with merely 
this roughage as a base. In your section 
you ought to be able to buy ear corn or 
coru-aud-cob meal readily, likewise you
