Experiments with fattening oxen. — Series Q differs from the others in 

 having three lots instead of two. The object of lot 3 was a teat of the 

 question whether the hay of the basal ration could be replaced by the 

 dry residue, an extra amount of the latter being used for this purpose- 

 As the hay used for lots 1 and 2 was richer in protein than the dry 

 residue, this deficiency in the latter was made up by lupines. The 

 results were most favorable for the dry residue. In series R the animals 

 did not consume the dry residue t'omi>letely at first and the ditfereuce 

 had to be made up with concentrated fodder, and furthermore the dura- 

 tion of tlie experiment was shortened by warm weather the middle of 

 April. Hence the results are not as satisfactory as they would other- 

 wise have been. The outcome of the two series is favorable both for 

 the dry residue and for the more liberal feeding. 



t^eries Q. — Experiments icith ensiled vs. dried diffusion residue. — Con- 

 ducted by Herr Rimpau in Schlanstedt. Fifteen young steers divided 

 into three lots of five each. In estimates of results tlie animal in each 

 lot having the smallest increase in live weight, was left out of account. 

 The remaining four animals in each lot averaged l,(Hi5, 1,01 L', and !>'.>7 

 pounds live weight, respectively. P.asal ration per head per day in

Series R. — Experiments with wet vs. dry diffusion residue. — Conducted 

 byllerr Kastendiek in Ampfurt. Ten oxen of Bavarian breed averag- 

 ing 1,507 and 1,448 pounds live weight, re.sj)ectively, divided into two 

 lots of five each. Basal ration per heatl i)er day in pounds, hay 5.5, chafl" 

 2.6 to 4.4, straw 1.1 to 2.2, cotton-sewl meal 4.4, rice meal 2.9 to 7.3, 

 and wet or dry diffusion residue in quantities as stated. Duration of 

 experiment from February 25 to April 15 — 49 days.
