JExperiments on the Feeding of Stock.

but since lie does not stare the general mistrust entertained for 
scientific results, he did not hesitate to apply the principles de- 
duced from these trials to his general system of stall-feeding. 
He rejects a forcing system of feeding which is irrespective of 
the animal's powers of assimilation. He condemns as useless 
and costly the employment of corn and cake from the beginning 
of the fattening process, because, before this is done, the stock 
should be well "ballasted" with an abundance of staying cheap 
food. Mangold, he says, or, better still, mangold-pulp, will 
always bring on both cattle and sheep, so that a very little corn 
will complete the fattening process. He points to the fact that 
the animal should be ripe before it is sold, because the value of 
prime meat per pound is often double that of lean inferior meat, 
so that in feeding, the chief profit is often derived from the extra 
value attached to the superior quality of the produce. 
Value of Mangold, Steamed, Raw, or as Pulp. 
To test the feeding-value of mangold-pulp, and correct the 
exaggerated impression entertained by some persons of the unim- 
portance of saccharine matter for feeding purposes, 3 lots, each of 
5 sheep, 23 months old, the first cross of Southdown, were fed, 
from November 28, 1858, to May 5, 166 days, the 1st lot on 
raw mangold ; 2nd, on pulp ; 3rd, on mangold steamed, with the 
addition to each sheep of nearly J lb. of bran and \ lb. of straw- 
chafF. The result showed that, if mangold is valued at 10s. pei- 
ton, pulp is worth 65. %d. per ton ; or since a ton of mangold gives 
about |- of a ton of pulp, the refuse from 1 ton of mangold is 
worth 5s. 
In this experiment steamed mangold showed a decided advan- 
tage over that given raw, since 59 lbs. steamed were found equi- 
valent to 70 lbs. raw. 
In addition to the straw-chaflf, the sheep picked a little straw 
out of the rack, but the amount was insignificant. 
The following table gives — 
A. The total increase in live weight. 
B. The total cost of the food : mangold being valued at lOs^ 
per ton, pulp at 6s. 8J., straw at 2Z., bran at 6/. 
C. An estimate of the total value of the manure, arrived at by 
the confinement of one sheep of each lot for 24 hours in the 
cell arranged for this purpose. 
D. The amount of roots or pulp consumed for the increase of 
1 kilogramme of live weight. 
E. The cost of that same increase. 
F. The nitrogen in the food for that increase. 
G. The percentage of nitrogen found in the meat.
