Bullock Feeding Experiments. 



3 l 3 



All the bullocks had per head per diem the following 

 quantities of artificial foods :— October 26th to January 19th 

 2 lbs. linseed cake ; 1), 2 lbs. common cotton-cake (2), 2 lbs 

 crushed wheat, and 2 lbs. crushed barley — in all 8 lbs. — 

 January 13th to February 14th, 10 lbs. per head per diem of 

 the same mixture. Throughout the experiment the beasts 

 were given as much hay and straw-chaff (half and half) as 

 they could eat. The actual amounts eaten, as determined by 

 giving weighed amounts, and weighing what was lefi over, 

 were as follows : — 



Lot I. — 5,805 lbs., or per head per diem, 16 lbs. 



Lot II.— 3,917 lbs. ,, 11 lbs. 



Lot III.— 3,620 lbs. ,, „ „ 10 lbs. 



Lot IV.— 3,625 lbs. „ 10 lbs. 



The object of the experiment being to determine the most 

 economical daily ration of roots, the following amounts were 

 given per head per diem to the several lots : — 



Lot I. — 3 stones — 42 lbs. 



Lot II. — 6 stones - 84 lbs. 



Lot III. — 9 stones = 126 lbs. 



Lot IV. — Ad libitum. 



Lois I. and IT. were given the actual amounts stated, 

 which they ate readily and completely throughout the whole 

 time. Lot III. also received the full amount, but did not eat 

 quite all of it, nor could Lot IV. be induced to eat more than 

 about eight stones per head per diem. The exact amounts 

 eaten, as determined by the same method as was used for 

 the chaff, were : — 



Lot L — 1,095 stones = 42 lbs. per head per diem. 

 Lot II. — 2,175 stones = 84 lbs. >> >> 

 Lot III. — 2,784 stones = 107 lbs. „ 

 Lot IV. — 2,955 stones = 115 lbs. ,, ,, 



Thus it will be seen that while Lots I. and II. ate the exact 

 amount of roots intended, the amount consumed by Lots III. 

 and IV. did not reach those set forth in the plan of the experi- 

 ment, in fact the greatest average weight of roots eaten per 

 head per diem was only just one hundred-weight. 



The method adopted in portioning out the food was to give 



(1) Containing oil, 9.32 per cent., albuminous compounds, 26.34 per cent. 



(2) ,, 4^22 per cent. , ,, ,, 24.46 per cent.
