173 Eleventh Annual Report. 



Lot I ate 15751b. of hay and 1333 lb. of Kaffir corn and gained 

 236 lb. or 1.68 pounds a day per head. 



Lot II ate 2853 lb. of alfalfa hay and gained 230 lb. in weight 

 or 1.65 pounds a day per head. 



ALFALFA HAY VS. ALFALFA HAY AND SORGHUM. 



The last period of the trial covered six weeks during which 

 Lot II had sorghum in addition to alfalfa. 



Lot I ate 1890 lb. of hay and 181 4 lb. of sorghum and gained 

 277 lb. in weight or 1.65 pounds a day per head. 



Lot II ate 2898 lb. of alfalfa hay and gained 280- lb. in weight 

 or 1.67 pounds a day per head. 



During the entire trial of sixteen weeks Lot I ate 4977 lb. of 

 alfalfa hay and 4394 lb. of other forage and gained 711 lb. in 

 weight; Lot II ate 8680 lb. of alfalfa hay and gained 6521b. in 

 weight. There is therefore a difference of 59 lb. gain in favor of 

 the lot receiving fodder in addition to alfalfa, a difference of about 

 fifteen pounds per head in sixteen weeks, a difference hardly de- 

 cided enough upon which to base conclusions in favor of the use 

 of a supplementary feed or otherwise, especially when the fact is 

 taken into consideration that practically all of this excess of gain 

 was made during the first period when the alfalfa hay fed was not 

 of the first quality. 



In the spring a piece of land adjoining the Station farm was 

 purchased and pasture land thus became available for our use. 



On May nth the steers used in the foregoing trials were re- 

 divided, two of each lot being transferred, so as to offset any pos- 

 sible influence of previous feeding, and put upon pasture. Each 

 lot of four had two acres of good alfalfa pasture in addition to 

 which one lot had sorghum and the other alfalfa hay. 



During the eight weeks of this trial the lot receiving alfalfa 

 hay gained 364 lb. or 1.63 pounds a day per head while the lot 

 getting sorghum gained 348 lb. or 1.55 pounds a day per head. 

 The difference of sixteen pounds gain on four steers in eight weeks 

 in favor of alfalfa hay over sorghum would not seem to indicate 

 that there is much difference in the feeding value of these two 

 feeds when fed to these steers, on abundant summer pasture. 



The results of the foregoing trials are collected in the fol- 

 lowing table:
