Jan., 1911] FEEDING SHEEP AND LAMBS. 



TABLE 1. MIXTURE OF GRASSES COMPOSING NATIVE. HAY. 



The chemical composition is as follows : 



TABLE 2. PERCENTAGE COMPOSITION OF NATIVE HAY. 



A fairly accurate, though not elaborate, digestion experiment 

 was performed with one of the sheep to determine the relative 

 digestibility of the native hay used in the feeding test.* 



The digestion coefficients are given in Table 3.

WEIGHTS AND GAINS OF SHEEP. 



Lots I and II contained the lambs; III and IV the aged ewes. 

 Lots I and III were supplied clover hay; II and IV, native hay. 

 The sheep in the different lots were selected, so as to be as nearly 

 alike as possible and thus obviate striking individual differences. 

 In lot IV, sheep No. 18 made negative gains, yet she appeared 

 perfectly healthy and vigorous and apparently ate her feed as 

 well as the others. 



* Acknowledgment is due to Mr. W. L. Adams, formerly assistant in chemistry at New Hampshire Experi- 

 ment Station, for successful prosecution of this phase of the experiment; also to bulletins No. 114 and No. 

 71 of the South Dakota and Nevada Agricultural Experiment Stations, respectively, from which valuable 

 information was gleaned as to methods of pursuing this work.
