Protein is greater in lean animals than in those that are fat. 

 The half- fat ox has 2.1 per cent, more protein than the fat ox; 

 the lean sheep 2.6 per cent, more than the fat sheep; and the 

 lean pig, 2.8 per cent, more than the fat pig. There is more 

 protein in the ox than in the sheep and more in the sheep than in 

 the pig. 



Fat. — The fat calf has 14.8 pounds of fat per 100 pounds 

 live weight; the half-fat ox 19. i pounds, the fat ox 30.1 pounds, 

 a difference of 15.3 pounds between the fat calf and the fat ox. 

 The lean sheep contains 18.7 pounds of fat per 100 pounds live 

 weight, the fat sheep 35.6 pounds and the extra fat sheep 45.8 

 pounds, or a difference of 27.1 pounds between the lean and 

 extra fat sheep. The lean pig contains 23.3 pounds of fat 

 per 100 pounds live weight and the fat pig 42.2 pounds, a 

 difference of 18.9 pounds. It is shown that there is 2.5 i>er 

 cent, more fat than protein in the half- fat ox and 15.6 per cent, 

 more in the fat ox; in the lean sheep 3.9 per cent, more and in 

 the fat sheep 23.4 per cent, more; in the lean pig 9.6 per cent, 

 more and in the fat pig 31.3 per cent. more. 



Nature of Gain in Fattening. — The findings of Lawes and Gil- 

 bert show that an increase in fattening means a great increase ini 

 the dry matter. The increase of fat is greater than protein. In 

 fattening oxen the increase of live weight will approximate Ij4 

 per cent, mineral matter, 7 to 8 per cent, of protein, 60 to 65 per 

 cent, of fat and 70 to 75 per cent, of dry matter. 



Should oxen be fattened while 'young and growing the in- 

 crease may amount to about 2j4 per cent, of nuneral matter, 

 about ID per cent, of protein and about 50 to 5.5 per cent, of fat. 

 The fattening increase of mature animals amounts to about three 

 quarters dry matter and one quarter water, while for young 

 growing animals two-thirds dry matter and one-third water 

 represents the proportion of increase. 



The increase for sheep amounts to about 2 per cent, mineral 

 matter, about 7 per cent, protein, from 65 to 70 per cent, fat, and 

 75 to 80 per cent, dry matter. The increase of mineral matter 

 of sheep is greater than for mature oxen because of the growth 

 of wool. In the final period of excessive fattening of sheep the
