The Balanced Ration." 1. What is the nutritive ratio of a ration consisting of equal parts of clover hay and oat straw? 2. What is the nutritive ratio of a feed of corn and skimmilk, mixed in the proportion of 2 lb. of milk to 1 lb. of corn? 3. The theoretical nutritive ratio of food adapted to the needs of a horse engaged in light work, is 1 : 7. Find the nutritive ratio of each combination of foods named below. and note whether it is wider or narrower than 1 : 7. (a) Two parts by weight of timothy hay to one of corn. (b) Two parts clover hay to one part of oats. (c) Five parts clover hay, five parts timothy hay, five parts corn, and one part oil meal. 4. The theoretical nutritive ratio of food adapted to fattening swine, first period, † is 1: 5.9. Find the nutritive ratio of each combination of foods named below, and note whether it is wider or narrower than 1 : 5.9. (a) One part by weight of corn to one part of oats. (b) Ten parts corn, ten parts skim-milk, and one part oil meal. 5. The theoretical nutritive ratio of food adapted to the needs of a milch cow weighing 1000 lb. and giving daily 22 lb. (about 11 quarts) of milk, is 1: 5.7. Find the nutritive ratio of each combination of foods named below, and note whether it is wider or narrower* than 1 : 5.7. (a) Three parts timothy hay and one part of corn. (b) Ten parts clover hay, ten parts corn stover, five parts corn, five parts wheat bran, and two parts oil meal. * A nutritive ratio in which the proportion of fat-formers to muscle-formers is large (as, oat straw, 1:33.7) is said to be a wide ratio; while one in which this proportion is comparatively small (as oil meal, 1:1.7) is said to be a narrow nutritive ratio. The nutritive ratio of corn (1:9.8) is wider than that of oats (1 : 6.2). + Writers upon this subject divide the fattening time into three periods. The proper nutritive ratio is wider for the second period than for the first; and wider for the third period than for the second. On the Farm. 1. If hills of corn are 33 ft. apart each way, how many hills to the acre? 2. If, in a field of corn planted as stated in Problem 1, there is on the average 14 lb. of corn to each hill, counting 80 lb. to the bushel to allow for shrinkage, what is the yield per acre? 3. If potatoes are planted in rows 3 feet apart, and in hills 2 feet apart in the row, how many hills to the acre? 4. If, in a field planted as stated in Problem 3, the yield on the average is 1 lb. to the hill, what is the yield per acre? 5. How many rods of fence will enclose a 40-acre square field and divide it into 10-acre square fields? 6. If the posts are placed exactly 1 rod apart, how many will be required for the fencing described in Problem 5? 7. How far must a man travel in plowing 3 acres of land (a) with a 16-inch plow? (b) With a gang of 2 12-inch plows? 8. How many 160-acre farms in a township 6 miles long and 6 miles wide? 9. If there is a 4-rod road on every section line* of a township exactly 6 miles square, (a) how many acres of the township in its roads? (b) How many acres of each square 160-acre farm are taken for roads? 10. If in mowing a square 10-acre field, one begins on the outer edge of the field and mows around it thus working towards the center, what part of the field is mowed when a strip 4 rods wide has been cut? 11. If corn is planted as stated in Problem 1, and when mature is cut and put into shocks each shock containing the corn from a piece 12 hills square, how many shocks to the acre? * A section is 1 mile square, and half of the width of the road is on each side of every section line.
