Tlie total (jnantitics of dig«*sti])h* nutrients are about as in WolflTs 

 stan(lar<l; tiie quantities of luoleiii are very large and tlie nutritive 

 ratios extremely narrow. Tlie gain in li\»' weight increases slightly, and 

 the liiiaiicial gain decidedly with the increase of ])rotein. It is to be 

 reiiieiiibered, however, tliat the valuation of manure from the nitroge- 

 nous food counts for a large part of tlie pecuniary gain. 



EXPEKIMENTS Vrvm F.VTTENING SHEEP. 



Of these, three series (L, M. and N) were made, one with one sided 

 iucrcjise of nitrogenous and two with one sided increase of non- 

 nitrogenous foods. The general ])laii was the same as that of the 

 exi)erimeiits with steers. 



Series L. — Kp'trts of one-sided increaw of nitrogenous foods. Cotton- 

 seed meal and irlirat Itran added in different tpmntities to ha.<ial ration. — 

 ("oiiducted by Heir Ibaune in Winningen. Thirty slieej), averaging 

 105.0 pounds live weight, divided into three lots of ten each. Basal 

 ration per ten head per day in pounds, licet diti'usion residue tio^ pea 

 straw 7.7, wheat cliatl" 7.20, and yellow lui>iiies 2.75; cotton-seed meal 

 and wheat bran in quantities as statcil. Duration of experiment from 

 January 23 to May 5 — 104 days.
