Feeding' stuff control in the year 1906, F. Barnstein {Siichs. Lanilw. 

 Ztfschr., r,5 (IHOI). Nos. 11, pp. 22i)-232 ; 12, pp. 251-25.'t; 13, pp. 2!)3-296).~The 

 analytical and other work carried on at the M<Jckern Ex|)eriment Station in con- 

 nection with feeding stuff inspection is reported and discussed. 



Feeding stuffs (Sachs. Landw. Ztschr., 55 (1M1), Nos. 20, pp. Jt51t-456; 21, 

 pp. ^n'h -i^J; 22, pp. 505, 506; 23, pp. 651-65^; 2Jt, i)p. 67^-677 ) .—Data are given 

 regarding the character and amount of analytical work carried on in connection 

 with feeding stuff inspection at the Ponimritz Experiment Station. 



Classifying corn bran (Saatcn, Diiinjcr u. Futtvrmarlct, 1907, No. 1/1, pp. 

 1153-1156). — From a discussion of the character and composition of corn by- 

 products the conclusion is reached that declarations on such goods should state 

 that they are milling by-products consisting principally of the l>ran and hull 

 portions of the grain and designed only for use as feeding stuffs. 



Concerning corn oil, H. Stiegeler {Pure Products, 3 (1907), No. 11, pp. 

 532-535). — In a discussion of corn oil and other corn by-i)roducts data are given 

 regarding the waste from a yeast factoiy operated according to the old Vienna 

 pi-ocess in which 20 to 25 per cent corn and a like amount of maize malt were 

 used. 



The agricultural value of French rye grass (Arrhenatherum elatius) and 

 of orchard grass (Dactylis glonierata), and the harmful results which fol- 

 low feeding sour grass, K, Holy {Ber. Physiol. Lab. u. Vers. Anst. Landw. 

 Inst. Halle, 1907, No. IS, pp. 96-190, j)!. 1, figs. 3).— The opinions of different au- 

 thorities as to the value of Fi-ench rye grass and orchard grass are briefly given 

 and compai'ative culture experiments with these and a number of other species 

 are reported. The author found that yellow oat grass (Ai'cna flareseeiis), as com- 

 pared with other valuable grasses, removed from the soil a very small quantity 

 of plant food, while at the same time yielding a large quantity of forage. 

 Orchard grass was most exacting with reference to soil fertility, and was found 

 to retain the percentage of stand in grass mixtures as indicated by the propor- 

 tion of seed sown only on A-ery fertile soil. 



In experiments wMth sheep the average coefiicients of digestibility of French 

 rye grass were as follows: Protein 45.07, fat 15.03, nitrogen-free extract 50.27, 

 crude fiber 55.2.5, and ash 2n..34 per cent. Similar values obtained for orchard 

 grass were protein 40.03, fat 20.82, nitrogen-free extract 57.44, crude fiber 59.10, 

 and ash 3G..34 per cent. 



From a chemical study of these 2 sorts of grass, the results obtained in the 

 digestion exi)eriments, and determinations of the nitrogen excreted in the 

 urine, the author concludes that the orchard grass is a less satisfactory feeding 

 stuff than the rye grass owing to the fact that the saw-like edges of the blades, 

 which contain a large amount of silica, irritate the intestinal tract. 



The article also contains an extended study of the constituents of so-called 

 sour hay (Carex si)p., etc.) from whicli the author concludes that the harmful 

 effects noted when such material is fed are also due to a similar cause. 



Dried beet pulp, J. Tribondeau iScmaine Ayr. {Paris'\, 26 {1907), No. 1370, 

 pp. 269, 270). — In an article quoted from rAffriciiItiirc dc la region du Nord, 

 data are given regarding the successful feeding of beet pulp to draft cattle and 

 other farm animals. 



Denatured sugar in the feeding of farm animals {Betterave, 17 (7.907), 

 No. .'i32, pp. 303, 30.'i). — A brief account of a test in which steers were fed 

 with favorable results sugar denatured with cacao pulp.
