On the Composition and Nutritive Properties of 



chaff, 49 Ibs. of linseed-cake, 34 cwts. 2 qrs. 21 Ibs. of mangold- 

 pulp. 



Lot II., 4 sheep fed upon mangolds, consumed 196 Ibs. of 

 clover-hay chaff, 49 Ibs. of linseed-cake, 33 cwts. 1 qr. 19 Ibs. 

 of mangolds. 



It will be observed that the sheep in the first lot consumed 

 1 cwt. 30 Ibs. more pulp than the quantity of roots eaten by the 

 sheep in the second lot. Each sheep was weighed on the 12th 

 of April, 26th of April, and May 10th. The weight of each 

 sheep at these periods, and their final increase, is given in the 

 subjoined Table : 



TABLE showing the Weight of each Sheep in Ibs. at beginning of Experiment 

 and at different times of Experimental period ', and Final Increase. 



LOT. I. Four Sheep fed upon Mangold-pulp. 



LOT II. Four Sheep fed upon Mangolds. 



It appears thus that the 4 sheep fed upon mangold gained 

 30J Ibs. more in weight than the 4 sheep fed upon pulp, although 

 the latter consumed 1 cwt. 30 Ibs. more of pulp. One of the 

 sheep in the first lot, it will be noticed, lost 3 Ibs. in weight. 

 This is due to the sheep having been affected with scouring 

 after it had been fed for some time upon pulp. The pulp, which 

 is very acid, is apt to produce this disorder. It ought there- 

 fore always to be given with a good deal of dry food. 



These experiments, though deficient in some respects, I think 

 still confirm sufficiently the theoretical opinion to which I have 

 been led by the analysis of the pulp and of mangold-wurzeJ.
