were fed, compares the average returns from all the trials with the 

 gains secured in 6 trials in which silage was fed without roots, as 

 follows : 



Average daily Digestible matter 

 gain in 100 lbs. gain 



Average of all trials 1.8 pounds 900 pounds 



Where silage was fed 1.8 pounds 763 pounds 



In the 201 trials reported the fattening animals made an average 

 daily gain of 1.8 lbs., requiring 900 lbs. of digestible matter for 100 

 lbs. of gain, while in 6 trials where silage was fed the daily gain was 

 also 1.8 lbs., but only 763 lbs. of digestible matter was consumed for 

 100 lbs. gain. Ingle comments thus : ' ' This is high testimony to the 

 feeding value of silage compared with roots." (567) 



565. Cassava and sv/eet potatoes. — At the Florida Station^ Stock- 

 bridge fed 3 lots of 4 steers each averaging 446 lbs. for 70 days to 

 test the value of sweet potatoes and cassava in beef production. 



Cassava and sweet potatoes for fattening steers. 



It is shown that cassava and sweet potatoes are satisfactory in beef 

 production when combined with pea-vine hay and cotton-seed 

 meal. The steers fed crab-grass hay required more than twice as 

 much concentrates for 100 lbs. of gain as those in the other 

 lots. (288-9)

 and Marshall fed 2 lots of 5 yearling steers each on the following
