Fj.i'i>rnmc)\is in beef itrothidioii. .1. II. (JrisdjiU' (pp. T.")-.S7). — Datu aro re- 

 ported on the cost of .uaiiis in short feil steers, in the production of baby beef, 

 and the comparative value of several feeds in the tn-ononiical production of 

 beef. The roughage used generally consisted of clover hay, silage, roots and 

 straw. Nine steers averaging 1,145 lbs. in vv^eight fed a grain ration of bran, 

 gluten, and oil meal for 100 days made an average daily gain of 2.77 lbs. per 

 head at a cost of 5.01 cts. per pound. The net profit per steer was $13.07. 

 Four yearlings averaging 472.5 lbs. in weight fed for 100 days on the same 

 ration minus the oil meal made an average daily dain of 2.17 lbs. per head 

 at a cost of 5.73 cts. per pound. The net profit per steer was $4.43. 



In the baby beef experiment 5 steers weighing 504 lbs. each on a limited 

 growing ration, of which the grain consisted of bran, gluten, oil meal, and 

 corn for 393 days made an average daily gain of 1.23 lbs. per head at a cost 

 of 5.5 cts. per pound, but there was a loss of $2.04 per head. Six steers weigh- 

 ing 593.3 lbs. each on a full fattening ration for 290 days made an average 

 daily gain of 1.01 lbs. per head at a cost of 0.02 cts. per pound. The average 

 I)rofit per head was $5.19. 



Three steers weighing 923 lbs. each, on a grain ration of bran and ground 

 corn for 70 days, made an average daily gain per head of 2 lbs, at a cost of 

 8.15 cts. per pound. The net profit per steer was $1.47. Three steers weighing 

 735 lbs. each, on a grain ration of bran and oil meal for 70 days, made an 

 average daily gain of 2.1 lbs. per head at a cost of 7.19 cts. per pound, and gave 

 a in-ofit per head of $1.20. Three steers weighing 837 lbs. each on a grain ration 

 of bran, gluten, and oil meal for 70 days, made an average daily gain of 1.53 

 lbs. per head at a cost of 9.9 cts. per pound. There was a net loss of 12 cts. 

 per steer. 



Five calves dropped in 1907 weighing at the start about 84 lbs. each, fed a 

 limited growing ration of which the grain consisted of bran, oil and gluten 

 meals, oats, and corn made an average daily gain for 729 days of 1.24 lbs. per 

 head at a cost of 4.06 cts. per pound. There was an average loss per steer of 

 S2.05. Six steers weighing 106 lbs. each, on a full fattening ration containing 

 the same ingredients, made an average daily gain in 020 days of 1.52 lbs. per 

 head at a cost of 4.88 cts. per pound. The profit per head was $5.19. 



Siviiie feeding cxiicrimcnts, J. H. Grisdale (pp. 82-80). — The aim of these 

 experiments was to compare gluten, imperial feed flour, and a mixture of oats, 

 oil meal and imperial flour as feeds for swine, and to obtain data as to the value 

 of potatoes as a supplement to these feeds. The main feeding period lasted 42 

 days and there were 10 pigs in each lot. The basal ration consisted of barley 

 and bran. The average daily gain on the supplementary ration of gluten and 

 potatoes was 1.35 lbs. per head at a cost of 4.84 cts. per pound. On the gluten 

 ration the average daily gain was 0.99 lb. per head at a cost of 0.11 cts. per pound. 

 On tlie imperial flour and potato ration the avei'age daily gain was 1.11 lbs. 

 per head at a cost of 4.6 cts. per pound. On the imperial flour ration the 

 average daily gain was 0.52 lb. per head at a cost of 8.41 cts. per pound. On a 

 mixture of oats, imperial flour, and oil meal the average daily gain was 1.17 

 lbs. per head at a cost of 4.68 cts. per pound. 



Cattle feeding experiment, A. Macitay (pp. 337, 338). — In this test western 

 rye grass was comi)ared with alfalfa. Two lots of 3-year-old steers weighing 

 a little over 1,000 lbs. each were fed for 16 weeks a basal i-ation of corn and 

 linseed meals. The lot receiving rye grass as a supplementary feed made an 

 average gain of 228 lbs. and the cost $49.07 per head. On the alfalfa ration 

 the avei'age gain was 177 lbs. and the cost .$.51.07 jier head. The net profit per 

 head on the rye grass was $11.10, and on the alfalfa $9.81.
