Wolff's standard for fatttMiing: sheep calls for digestible nutrients in 

 pounds per 1,000 pounds live weight, protein 3.2, fat O.G, carbohy- 

 drates 14.8, with a nutritive ratio of 1:5, and .50,000 Calories of energy. 

 As compared witli such a .standard, the ration of lot 1 in each of the 

 three series of ex]>eriraents was liberal in total quantity of nutrients 

 and large in amount of ]irotein. The largest gains in live weight and 

 best financial returns were in series N. in which the width of the ration 

 was in the neighborhood of 1:5. 



The eflects of the nitrogenous and non-nitrogenous rations with fat- 

 tening steers and sheep are recapituhitcd in the talmhir statement 

 herewith. Wohf 's standards provide sdinewhat ditlrrciit quantities for 

 diflterent fattening periods. The figures here ust'd are means.
