168 EXPERIMENT STATION RECORD. 



gluten meal and other corn by-products, linseed cake and meal, cotton-seed meal, 

 distillers' grains, goose wheat, fall wheat, broken soda biscuit or crackers, rice 

 meal, and condimental feeds. 



Mealies grown at Potchefstroom (Tiaiisraal Ayr. Jour., Jf {1906), No. H, 

 Pl>- SofJ-ifJl). — Analyses of 10 samples of corn are reported. On an average 

 the samples were drier than American-grown corn, doul)tless owing to the dry 

 South African climate. They contained " less protein and fat, but more starch, 

 while they are about the same so far as ash and crude fiber are concerned." 



" It would appear from these analyses that flint varieties of mealies, so far 

 as chemical composition goes, are decidedly preferable for feeding purposes to 

 dent varieties, and that the soft corn is poorest in ash, protein ('flesh form- 

 ers"), and fat. though richest in starch." 



Castor bean by-products, A. Halenke and M. Kling {Landw. Vers. Stat., 

 (j-'i (1906). :\(). 1. pp. .'>l-86, figs. i3).— Available data regarding the histology 

 of castor-bean seed, the composition of seeds and by-products, castor-bean prod- 

 ucts as adulterants, and other questions are suunnarized. 



Blood molasses as a feeding stuff, G. Monti ni {Staz. Sper. Agr. Ital., 38 

 (190.')). \o. 9, pp. 7s.')-79S). — Tests with farm animals are briefly summarized, 

 showing the vahie of blood molasses as a feeding stuff. 



Calculating rations, A. Stutzek (BcreclniiDuj dcr Fiittcrrationcn. Berlin: 

 Paul I'urey, 1906, 2. cd.. pp. 81). — This is the second, revised, and enlarged 

 edition of this popular treatise, which discusses the food requirements of 

 different farm animals, the composition of feeding stuffs, method of calculating 

 rations, and related (piestions. 



Concerning the composition of animal fat, C. Schneider and S. Blumen- 

 JELD (C'hein. Ztij., 30 (1906), Ao. 6, pp. 53, 5-'f). — The chemical and physical con- 

 stants of fat from seal, lynx, bear, crane, and other sorts of game are reported. 



Live stock, J. H. Grisdale (Canada Expt. Farms Rpts. 190,i, pp. Jfl-Sl, 73- 

 75). — It is estimated that the average cost of feeding and care of work horses 

 at the station is 32.33 cts. per working day. 



The extensive use of bran in the place of oats has effected a very considerable 

 saving in the cost of horse feeding during the year, and the value of bran and 

 oats in different proportions as compared with oats alone was studied with 5 

 lots containing 2 work horses each, the grain ration being supplemented with 

 mixed hay. On some of the rations there were small gains and on others losses, 

 but in general the conclusion was reached that bran may " very safely and very 

 profitably constitute a very large percentage of the meal ration of working 

 horses. Probably equal parts bran and oats might be taken as a fair propor- 

 tion in which to mix the two feeds. Where the mixture is being fed to horses 

 with sound teeth there does not seem to be any particular advantage in grinding 

 llie oats." 



Beef production, .1. II. (Jrishai-e (Canada Expt. Farms lipts. 1905, pp. 62- 

 70). — In short /•. long feeding jieriods a lot of 9 steers was fed for 127 days in 

 comparison with a similar lot fed 202 days. The average daily gains per 

 steer in the 2 cases were 1.85 and 1.83 lbs., and the cost of a pound of gain 6.7() 

 and 7.38 cts., respectively. 



The influence of age on the cost of beef was studied, the average daily 

 gain with 3-year-olds being l.G.") lbs. per head at a cost of G..'j2 cts., with 2-year- 

 olds 2.1(5 lbs. and 5.99 cts., with yeai'lings 2 lbs. and 4.3 cts., and with skim- 

 milk calves under 8 months 1.54 lbs. and 3.4 cts. 



Continuing earlier work (E. S. R., 17. ]>. 171), the cost of ])roducing baby 

 beef was studied with steers 2 years old, with steers 13i months old. and with 

 calves, full fattening rations and limited growing rations being compared in
