The Ensilage of Fodder.

At the Massachusetts (Hatch) Station 1 in a feeding trial with 

 dairy cows fed equal amounts of hay and grain, those getting 30 Ibs. 

 of corn silage daily gave 4 per ct. more milk than those getting 40 

 Ibs. of mangels daily. (563, 656, 757-8) 



353. Relative cost of beets and silage. At the Pennsylvania Sta- 

 tion 2 Waters and Hess estimated the cost of 1 acre of corn placed 

 in the silo at $16.17, while to grow and house an acre of beets cost 

 $57.54. In this case it cost 5 times as much to produce 100 Ibs. of 

 dry matter in roots as in corn silage. At the Ohio Station 3 Thorne 

 found that to grow and harvest an acre of beets yielding 15.75 tons 

 and containing 3,000 Ibs. of dry matter cost more than an acre of 

 corn yielding 57 bushels of grain and containing 6,000 Ibs., or twice 

 as much, dry matter. Grisdale of the Ottawa Experimental Farms 4 

 found turnips more expensive and not much more effective than corn 

 silage for milk production. Sugar beets proved the best of the root 

 crops, but were more expensive than corn silage. After experiment- 

 ing with steers fed roots and corn silage with hay and grain, Day of 

 the Ontario Agricultural College 5 concludes that when a ton of roots 

 is worth $2, corn silage is worth $2.44 per ton for beef production. 



354. Southern v. northern seed for silage corn. At the North 

 corn plants from southern seed grow much larger than those from 

 northern seed. The merits of the two classes of seed corn have been 

 tested at several stations, as the data given below will show. 



Yield of corn forage at the North from northern and southern seed.
