the mixed grain feed the results were contradictory. There was but very little 

 difference between the 2 animals. 



In consequence of the relatively small losses in the feces observed in 1907, 

 the total energy of the hay which was metabolizable was higher than in the 

 two previous years, the averages for both animals being as follows: 1905, 40.11 

 per cent: 1906. 41.2 per cent: and 1907, 4").()3 per cent, and the percentage of 

 "digested" energy metabolizable, 1905, 79.99; 1906, 79.73; and 1907, 78.34 per 

 cent. There was but very little apparent difference between the 2 animals as 

 respects the percentage of energy metabolizable. The average results of the 

 availability of metabolizable enei-gj' is shown in the following table:

The energy values of the feeding stuffs, technic employed, and method of 

 feeding during intorme<llate iierio^ls are also given in detail. 



Feeding experiments with beef cattle, R. S. Cubtis (North Carolina 8la. 

 Bui. 218, pp. 29-JtJf, figs. 10). — The object of these experiments was to determine 

 the difference in feeding value of corn stover, corn silage, and cotton-seed hulls 

 when fed with cotton-seed meal. Western North Carolina steers, principally 

 Shorthorn grades and weighing about 900 lbs., were used, and the same amount 

 of cotton-seed meal was fed to each of the three lots. The feeds u.sed were 

 rated per ton as follows: Cotton-seed meal $30. cotton-seed hulls $S. corn silage 

 $2.75, and corn stover $S. In figuring the profits manure produced was credited 

 at $2 per ton. 



Three lots of steers were fed for 112 days during the winter of 1909-10 an 

 average of 8.14 lbs. cotton-seed meal per steer daily. In addition the steers 

 in lot 1 were fed 16.52 lbs. corn stover and 23.17 lbs. corn silage; lot 2 was 

 fed 35.36 lbs. corn silage; and lot 3, 17.92 lbs. cotton-seed hulls per steer daily. 

 Lot 1 made an average daily gain of 1.31 lbs. at a cost of 17.94 cts. per pound 

 and were fattened at a profit of $0.74 each. The corresponding figures for lot 

 2 are 1.35 lbs., 16.02 cts., and $9.20, and for lot 3, 1.43 lbs., 16.07 cts., and $8.58. 

 These steers were bought at $4 and sold at $5.75 per hundred pounds live 

 weight. During the winter of 1910-11 3 lots of steers were fed for 112 days 

 an average of 6.77 lbs. cotton-seed meal daily per steer. In addition lot 1 

 received daily 20.8 lbs. corn stover and 23.64 lbs. corn silage; lot 2, 32.55 lbs. 

 corn silage: and lot 3, 21.6 lbs. cotton-seed hulls. These steers cost $4.50 per 

 hundred pounds. Lot 1 gained 1.3 lbs. daily at a cost of 17.17 cts. per ])Ound, 

 sold at $5.90, and made a profit of $1.99 each. Lot 2 gained 1.23 lbs. each daily, 

 at a cost of 15.11 cts. per pound, sold at $6.00, and made a profit of $6.79 per 

 steer. Lot 3 gained 1.45 lbs. each daily at a cost of 14.19 cts. per pound, sold 

 at $5,725, and made a profit of 31 cts. per steer. 



Though in each case the steers fed cotton-seed meal -and hulls gained more 

 than the other lots, the author states that the quality of the carcass was not 

 as desirable, nor was the dressing percentage as high as that for the two lots 

 receiving silage and stover. The statement is made that the high cost of gains
