with each other in regard to some of their most important 
constituents, the proportions of dry matter, woody fibre, and 
nitrogen, being specially mentioned as the base of calculations. 
2. That the purchased food should be the same in each 
experiment, and not so large in quantity as to exert too great 
an influence upon the increase of the animals ; if cake and 
meal were used, about 6 lbs. per head daily of the mixture should 
be sufficient, 
3. That if grass silage be used, the parallel experiment should 
be with meadow hay ; if clover silage, then with clover hay. 
The Committee decided to carry out the experiment on the 
lines of Sir John Lawes's recommendations, using for the 
bullocks, per head per day, 3 lbs. of decorticated cotton-cake 
and 3 lbs. of maize-meal, in addition to which four bullocks 
were to receive a mixture of swedes and hay-chaff, and the other 
four only silage, the quantities to be arranged after analysis of 
the different foods, so that the amounts of dry substance, woody 
fibre, and nitrogen should be as nearly as possible equal in the 
silage and in the mixture of roots and hay-chaff. 
Analyses were made by me of the silage taken from silo 
No. 1, of the swedes, and of the hay-chaff and other foods. The 
essential constituents, as decided on for the regulation of the 
quantity of food, were — 
Dry Matter. 
Woody
