On the Fattening of Oxen. 
with 5 ; and one with G animals. The numerical results are 
arrano^ed in Tables as follows : — 
In Tables I., II., 111., IV., V., and VI., the actual weights, and 
gain in weight, of each animal. 
In Table VII. the total quantities (both fresh and dry), of food 
consumed, litter used, and increase and dung obtained, in each 
experiment. 
In Table VIII. the average amounts (both fresh and dry) of 
food, litter, increase, and dung, per head per week. 
In Table IX. the average amounts (both fresh and dry) of 
food consumed, per 100 lbs. live-weight per week. 
In Table X. the average amounts (both fresh and dry) of food 
consumed, to produce 100 lbs. increase in live weight. 
In Table XI. is given a summary of the results of the feeding 
of oxen at VVoburn, side by side with those obtained by other 
experimenters. 
In Table XII. the average results of experiments on the feed- 
ing of oxen, are compared with similar particulars relating to 
sheep and pigs. 
In Tables XIII. and XIV. the proportion of the dung obtained 
to the food consumed, and litter used. 
In the brief remarks which follow attention will be chiefly 
confined to the amounts of food consumed in relation to a given 
weight of animal, and to produce a given amount of increase ; but 
a few observations will also be made on the amounts of fresh and 
dry dung obtained for given amounts of fresh and dry food and 
litter used. The question of the composition of the dung, in rela- 
tion to that of the food, will be considered on a future occasion. 
Experiment 1 included 6 Herefords and 5 Devons ; and Ex- 
periment 2, 7 Herefords and 5 Devons. The animals were 
taken from grass, weighed, and put into the boxes, on September 
18, 1849. Those of Experiment 1 were fed upon crushed oil- 
cake, clover-hay chaff, and Swedish turnips ; and those of Expe- 
riment 2 on a cooked mixture of 2 parts linseed-meal, 2 parts 
barley-meal, and 1 part bean-meal, with chaff and roots as in 
Experiment 1. During the first period of the experiment, from 
September 18 to October 17, the food, litter, and dung were not 
accurately weighed. On October 17, the oxen were re-weighed, 
and the boxes emptied ; and from this date to the end of the ex- 
periments, about the middle of December, the whole of the food 
and litter were accurately weighed ; and at the conclusion, the 
whole of the dung of each lot was weighed, turned over, well 
mixed, and re-weighed. Several samples of 100 lbs. each were 
then taken from the heap ; to some of which acid was added to 
prevent the loss of ammonia. Fair average samples of all the 
foods, and litter, were also taken.
