EXERCISE 11. THE SILO ON THE STOCK FARM 



Explain the relation between the feeding surface of silage (the diameter 

 of the silo) and the size of the dairy herd to be fed. 



What are the outside limits for the diameter of silos adapted to practical 

 farm conditions? 



Example 1 : How large should a silo be built, and how large a field should 

 be planted to Indian corn, for supplying a herd of 25 cows, to be fed 30 pounds 

 of silage per head daily for a period of 150 days? 



Example 2: How long will the silage last in a completely filled silo, 16 

 feet in diameter, 36 feet high, when fed at the rate of 28 pounds per head 

 daily to a herd of 35 dairy cows?
