128 ELEMENTARY AGRICULTURE 



6. A farmer owns six cows : Bess, Spot, Brindle, 

 Bos, Kate and Red. 



Bess gives 22 Ibs. of milk daily, which tests 3.8%, 

 Spot gives 15 Ibs, of milk daily, which tests 4.2%, 

 Brindle gives 30 Ibs. of milk daily, which tests 3.0%, 

 Bos gives 20 Ibs. of milk daily, which tests 3.5%, 

 Kate gives 14 Ibs. of milk daily, which tests 3.2%, 

 Red gives 24 Ibs. of milk daily, which tests 5.2%. 



Figure out the dairy value of each. Which is the 

 best cow? The poorest one? Classify them in order 

 of dairy value. 



7. Figure out the number of pounds of milk given 

 by each cow in a month, and the value of it in butter- 

 fat at 25 cents per pound. 



8. Two herds of ten cows each are compared : 

 The Jerseys average 18 Ibs. of milk each daily; the 

 Holstein-Freisians average 30 Ibs. of milk each daily. 

 The Jerseys test 5.4 per cent; the Holstein-Friesians 

 test 3.2 per cent. Which is the more valuable herd? 



9. With butter-fat at 30 cents per pound, what is 

 the monthly average per cow of each herd ? 



10. Pupils will furnish actual data from home for 

 other dairy problems.
