FEEDING ANIMALS. 



14.5 per cent, of the albuminods of oats will pass into the 

 solid excrement. The digestible part will pass into the 

 blood ; and if the sheep are not increasing in weight, or 

 suckling lambs, 85.5 per cent, of the albuminoids will pass 

 in the urine, so that all the nitrogen received in the food 

 will be voided in the solid and liquid excrement. But if 

 the animals are full-fed and are increasing in weight, then 

 the increase will reduce the quantity of manurial constitu- 

 ents in the excrement. From the German tables of exper- 

 iments, it is estimated that the following percentages are 

 stored up and voided as excrements when fed on barley- 

 meal. 



NITROGEN STORED UP AND VOIDED FOR 100 CONSUMED. 

 Table No. 2. 



ASH CONSTITUENTS STORED UP AND VOIDED FOR 100 CONSUMED. 

 Table No. 3. 



An examination of these tables will show, in the case of 

 fattening sheep, what proportion of the valuable elements 

 of the food are returned to the soil, or may be returned, to 

 prevent exhaustion. Over 95 per cent, of the nitrogen and 

 ash constituents are voided in the excrement in the cases of
