DIGESTION EXPERIMENTS WITH SHEEP.

6.38 per cent, fiber, 81.40 per cent, extract matter and .28 per cent. fat. 

 The mangels were very low in protein, fiber and fat, and high in extract 

 matter. They were fed in combination with hay only, and constituted 

 from 40 to about 47 per cent, of the total dry matter of the combined 

 ration, which had a nutritive ratio of 1:11 to 1:13. The coefficients are 

 quite satisfactory, showing the dry matter to be 87, the protein 51 and 

 the fiber and extract matter 95 per cent, digested. It is possible that 

 the mangels improved the digestibility of the hay somewhat, but it is 

 regretted that they were not fed also with a combination of hay and a 

 protein concentrate in order to note if they would not have had a more 

 pronounced effect. 



(d) Pumpkins. 

 Summary of Coefficients of Entire Pumpkins. 



Two lots of pumpkins, grown on two different farms in successive years, 

 were used. One lot was tested whole, and also without the seeds and 

 connecting tissue. The whole pumpkins averaged 87.53 per cent, water, 

 and the dry matter contained 7.74 per cent, ash, 15.60 per cent, protein, 

 15 per cent, fiber, 49.37 per cent, extract matter and 12.29 per cent. fat. 

 The edible portion contained 94.58 per cent, water, and its dry matter 

 consisted of 8.81 per cent, ash, 13.74 per cent, protein, 17.33 per cent, 

 fiber, 57.56 per cent, extract matter and 2.56 per cent. fat. 



Wider variations occur in the digestibility of the different ingredients 

 by the two sheep than are desirable. In case of Series XX., Periods 3
