EXPERIMENTAL FARMS 



7-8 EDWARD VII., A. 1908 

 GLUTEN, OIL MEAL, COTTON SEED MEAL VS. BRAN AND OATS. 



During the winter of 1906-7 an experiment was undertaken to gain some infor- 

 mation as to the value of gluten, oil meal, and cottonseed meal as feeds in comparison 

 with bran and oats. 



The tables which follow give a full history of the experiment. 



It will be seen that while these feeds, especially oil meal and gluten, checked the 

 falling off in millv flow they at the same time raised the cost of production so that 

 the period when bran was being fed holds first place in economy. Gluten meal period 

 is very close behind, however, and has the advantage of having not only checked the 

 natural decrease in milk flow but even induced a slight incre'ase.
