The gains in live weight during the first two feeding 

 periods are not of particular interest so far as the 

 rations are concerned, but they seem to depend upon 

 the individuality of the cows. Ada gained 16 lbs. on 

 the farm-grown ration and practically held her own on 

 the ''oil mill ration" losing only 1 pound. Queen lost.
