PRACTICUMS 
re Do horses have teeth in front in both jaws? Do cattle? Do 
sheep? 
2. Cost or Nutrients.—(Consult appendix for digestible nu- 
trients in feeding stuffs.) 
(a) When corn is worth $25 a ton, what is the value of a pound 
of digestible protein? Of a pound of total digestible nutrients? 
(b) When cottonseed meal can be bought for $32 a ton, and pro- 
tein only is required for balancing a dairy ration, what is the cost of 
a pound of digestible protein? 
(c) If protein only is needed, in which feeding stuff—cottonseed 
meal at $32, linseed meal at $32, corn meal at $25, or wheat bran at 
$28 a ton—can it be most cheaply purchased? Show by figures. 
3. RaTIOoN ror Datry Cows.—Compound a ration for dairy cows, 
averaging 1,000 pounds in weight, and yielding 22 pounds daily, 
using 10 pounds of corn stover, 10 pounds of clover hay, and 40 
pounds of corn silage for the foundation and such amounts of cot- 
tonseed meal, wheat bran and gluten as wi!l be necessary to balance 
the ration. 
4, RATIONS WITH REFERENCE To Cost.—(a) Use the following 
feeding stuffs for compounding a ration for a cow weighing 1,000 
pounds and yielding 22 pounds milk daily. Timothy hay worth $20 
a ton, corn stover $5, corn $25, oats $30 and bran $28. What is the 
daily cost of the ration? 
(b) Use the following feeding stuffs for compounding a ration 
for the same cow: Alfalfa hay, worth $15 a ton; clover hay, $12; 
corn silage, $2; cottonseed meal, $32, and gluten, $25. What is the 
cost of the ration? 
(c) What is the difference in cents of the daily cost between 
these two rations? 
(d) Suppose both rations are available for a dairy herd of 40 
cows to be fed six months. What would be the total cost of each 
ration and the saving in cost if the cheapest is used? Is not the 
cheapest ration also the best? 
5. Home Usep Ration.—What quantities each of five feeding 
stuffs used at your home may be used in combination so as to fur- 
nish an approximately balanced ration for a dairy cow weighing 
1,000 pounds and yielding 22 pounds of milk? (For digestible nu- 
trients, see appendix.) 
6. Using for the purpose timothy hay, corn, oats and bran, how 
many pounds each will be required for feeding a horse weighing 
1,000 pounds and doing light work? 
7. A farmer fed each of his cows about 10 pounds of timothy hay, 
35 pounds of corn silage and 5 pounds of corn and cob meal daily. 
Suggest some changes that might be made to make this ration better.
