The total quantities of nutrients in these experiments were rela- 

 tively small. Thus, Wolff's standard for fattening oxen per 1 ,000 iwunds 

 live weight, calls for protein 2.7, fat 0.6, and carbohydrates 14.8 pounds, 

 with a nutritive ratio of 1 : 6 and a fuel value of 35,070 Calories. The 

 smallest average increase of live weight and of profit in these experi- 

 ments was with the largest amount of watery food. 



Series I. — Beet (liffusion residue and potato residue added in different 

 quantities to basal ration. — Conducted by Herr Wagner in Warnisdorf. 

 Nine oxen averaging 1,760 pounds live weight, divided into three lots 

 of three each. Basal ration per head per day in pounds, hay 5.5, straw 

 8.8, bran, 2.2, and cotton-seed meal and maize in quantities sufficient to 

 make the desired amounts of total digestible nutrients in the ration 

 when the beet and potato residues were added; beet diffusion residue 

 and potato residue in quantities as stated. Duration of experiment 

 from January 23 to April 4 — 74 days.
