EXPERIMENT STATION, 



[Jan. 



Sheep III. digested the feed rather better than Sheep IV. 

 Attention has already been called to the fact that the Old 

 Sheep had a slightly stronger digestion than the others, but 

 why the difference should be so noticeable is difficult to 

 explain. 



The protein in the sample of Green Diamond experimented 

 with was better digested than that in the several other sugar 

 feeds. The results secured with Sheep III. and the average 

 results of all trials agree closely; and it may safely be said 

 that this feed has about the same type of composition and a 

 like degree of digestibility as the other sugar feeds examined. 

 The average results of all trials show the sugar feeds to be 

 only moderately digestible, being noticeably less so than either 

 flour middlings or gluten feed. 



Sea Island Cottonseed Meal. — This meal contained a 

 large quantity of hulls, showing only 24-25 per cent, of 

 protein, 5-6 per cent, of fat and some 18 per cent, of fiber. 

 It is claimed that the hulls of this variety of seed are thin, 

 and that it is not possible (or profitable) to thoroughly sep- 

 arate them from the meats.

Sheep TV. was not able to digest the meal as fully as was 

 Sheep Y. The cause of this difference is due largely to the 

 indigestible character of the tough, woody fiber. The co- 

 efficients secured at the Maine station for a similar meal are 

 somewhat lower than those obtained in the present experi- 

 ment.
