Pen No. 1 contained one Berkshire, one Middle Yorkshire, and one Tam- 
worth-Berkshire ; they were fed on ground maize (uncooked). 
_ Pen No. 2 contained two Tamworth-Berkshires, and were fed on cooked 
maize. 
Pen No. 3 contained two Tamworth-Berkshires, and were fed on ground 
maize (uncooked), 
Pen No. 4 contained two Middle Yorkshire-Berkshires, and were fed on 
cooked maize. 
The Berkshire and Yorkshire were from purebred stock, and the Tam- 
worth-Berkshires were from Berkshire sows by Tamworth boars; the Middle 
Yorkshire-Berkshires were from Berkshire sows by Middle Yorkshire boars. 
The ground maize was fed as a thick slop, and the boiled maize was fed in 
the liquid in which it was cooked. The pigs were fed three times per day, as 
much food as they would readily eat up, and in addition an ample supply of 
water. The cooked and uncooked foods were fed so as to afford an opportunity 
of ascertaining the effect, if any, on the quality and quantity of the flesh 
produced. It will be seen from the figures in Table I., pen 1, that the daily 
average gain of the pigs was as follows:—Berkshires, 2°28 lb.; Middle York- 
shire, 2°08 lb. ; Tamworth-Berkshires, 1°97 Ib. In comparing pens 2 and 3 it is 
found that the daily average per pig in pen 2 is 1°93 lb., and in pen 3 the 
average daily gain is 2°041b. The daily consumption per pig in pen 2 was 
10°12 lb. of boiled maize, and in pen 8, 10°31 Ib. of ground maize. Pen 4: 
The daily average gain of each pig was 1°84 lb., and the food consumed, 
9:89 lb. per head. 
By referring to the summary of results we find that the pigs in pen 2, 
fed on boiled maize, consumed 5°18 Ib. for each lb. of increase; and pen 3 
consumed 5:04 lb. of ground maize for each lb. of increase; pen 4 consumed 
4:97 lb.; pen 1 consumed 4°72 Ib. of ground maize for each lb. of increase. 
The feeding value of maize, as fed to the pigs, computed on the basis of a 
pound of increase being worth 4d. per lb. was in the case of pen 1, 3s. 11:4d. 
per bushel; pen 2, 3s. 71d. per bushel; pen 3, 3s. 83d. per bushel; and 
pen 4, 8s. 10°4d. per bushel.
