CAL-CARBO 
The Sensational New 'High 
Calcium Feeding Supplement 
Makes All Feeds and Pasture 
Give Maximum Feeding Results 
DAIRY COWS 
The dairy cow is the hardiest animal on the farm. At one and the same time 
she is expected to produce from 15 to 50 pounds or more of milk daily, develop a 
calf that will be born alive, strong and thrifty, and maintain her own health and 
vigor so she can carry on these tasks year after year with little or no rest. 
To do all these profitably, the dairy cow must have an adequate and constant 
supply of certain necessary substances. And one of the most important of these sub¬ 
stances is calcium. 
Calcium is the principal mineral element in the skeleton, in the unborn calf, and 
in milk. Yet with the exception of some legume hays, calcium is lacking in prac¬ 
tically all feeds. 
Cal-Carbo is 98.99% pure calcium carbonate plus other vital minerals, and be¬ 
cause of its flour fineness, Cal-Carbo dissolves instantly and digests easily with no 
waste. 
Cal-Carbo is required in all livestock rations. 
CAL-CARBO—Price per 100 lbs., $0.80. If interested in quantities ask for special 
prices. 
BEEF CATTLE 
The high feeding value of Cal-Carbo in beef 
cattle rations is shown in the three-year tests con¬ 
ducted at the Kansas Experiment Station. At a 
cost of only 18 cents per head, profits were in¬ 
creased as much as $7.69 per head on beef calves 
when small amounts of Cal-Carbo were added 
to the prairie hay ration. This was even a bigger 
profit than was returned on a similar lot fed 
alfalfa. Tests conducted at the Oklahoma and 
Nebraska Experiment Stations confirmed these 
remarkable results. 
Low grade roughage, with Cal-Carbo added, 
gives alfalfa results in making beef and produce 
gains at much lower cost. 
Silage alone, when supplemented with Cal- 
Carbo, is a satisfactory roughage for cattle on 
which profitable gains can be made. 
Cal-Carbo makes pasture and range grass more 
efficient, just as it increased the efficiency of 
prairie hay in the Kansas tests. 
Cal-Carbo even increases the efficiency of al¬ 
falfa and lowers the cost of gains per 100 lbs. 
of beef. This reduction in cost is equal to ten 
times the cost of the Cal-Carbo fed. 
Cal-Carbo-fed cows produce large, strong, 
thrifty calves because Cal-Carbo is to the bones 
of an animal what cement is to a concrete 
foundation. 
Cal-Carbo fed to young stock supplies the neces¬ 
sary bone-building calcium for producing rapid 
growth and large strong frames on which future 
profits largely depend. 
Cal-Carbo prevents and often remedies many 
common deficiency disorders such as creeps, nu¬ 
tritional abortion, milk fever, bone and stick 
chewing. 
Cal-Carbo costs less than 2c per head a month 
to feed beef cattle on full feed, and only a frac¬ 
tion of a cent per head a month for range cattle 
. . . yet profits are increased many dollars. 
SWINE 
Hog raisers can increase average daily gain 
over 50%, and the amount of feed required per 
100 lbs. gain can be reduced nearly a hundred 
pounds, when Cal-Carbo is added to the ration 
of fattening hogs on dry lot. These outstand¬ 
ing results were shown in a test made by the 
Ohio Experiment Station, which reports: “The 
mere addition of 2 lbs. of ground limestone to 
100 lbs. of a mixture of corn, middlings, oil meal 
and salt fed on dry lot, made the difference be¬ 
tween a reasonable degree of success and failure”. 
In another test the Ohio Station says: “Ground 
limestone, even more than alfalfa, caused pigs 
to make rapid gains.” 
Cal-Carbo fed to brood sows insures more pigs 
to the litter, stronger and more vigorous litters, 
and a greater number reaching weaning time 
with good weight and ability to make rapid gains. 
Cal-Carbo-fed brood sows have an ample supply 
of milk for the litter and at the same time main¬ 
tain their own strength and health. Cal-Carbo 
prevents posterior paralysis which causes the loss 
of some of the best brood sows. 
IODIZED CALCIUM CARBONATE 
Iodized Calcium Carbonate is manufactured by 
a wet process by which every calcium particle 
is thoroughly coated with Iodine held in place 
by chemical-physical combination. 
The inclusion of traces of Iodine in livestock 
feeds increases their digestibility, thus enabling 
cattle, hogs and sheep to make more milk, meat 
and wool, and hens to produce more eggs and 
better eggs, harder shells and high hatchability. 
Price per 100 lbs. 85c. Ask for quantity prices. 
PERFECTION MINERAL MIXTURE 
For Cattle 
Composed of Steamed Bone Meal, Iodized Cal¬ 
cium Carbonate, Iron Oxide, Manganese Sulphate 
and Salt. „ . 
Mix two pounds per 100 lbs. of feed, or place 
in a container so that it is available at all times. 
When fed in containers it is necessary to sup¬ 
ply common salt separately in order that animals 
will not consume more of the mineral mixture 
than is needed. Per 100 lbs. $2.25.
