ANIMAL PKODUCTION. 291 



Dried brewers' grains and distillers' grains, Dietrich {Landw. Vers. Stat., 58 

 {1903), No. 3-4, pp. 24-1-262, figs. 18). — A number of forms of apparatus for drying 

 brewers' and distillers' grains are described. 



Oats, E. Haselhopf and F. Mach {Landw. Vers. Stat., 60 {1904), No. 3-4, pp. 161- 

 206, pis. 2). — Data regarding the composition, structure, and feeding value of oats 

 and oat products and related topics are summarized and discussed. 



Composition and food value of the leaves of sugar beets, L. Grandeau 

 ( Jour. Agr. Prat., n. ser., 8 {1904), No. 30, pp. 106-108). — Asummary of data on this 

 topic. 



The terminology of the constituents of feeding stuffs, A. Gregoire {Bui. 

 Cercle oV Etudes Agron. [Brussels'], 1903, No. 8, pp. 369-375). — The terminology pro- 

 posed for the constituents of feeding stuffs is practically the same as that followed 

 in the United States, Germany, and elsewhere. 



The digestibility of peat as an absorbent for molasses in molasses feeds, 

 T. Pfeiffer and A. Einecke {Mitt. Landw. Inst. Univ. Breslau, ..' {1904), No. 4, pp. 

 683-694). — Experiments with sheep showed that an appreciable quantity of the total 

 organic material, nitrogen-free extract, and pentosans of peat meal was digested. 

 The author calls attention to the fact that molasses peat has more value than is ordi- 

 narily believed. 



The digestibility of pentosans, S. Weiser (Landw. Vers. Stat., 58 {1903), No. 

 3-4, pp. 238-240). — Experiments are briefly reported on the digestibility of pentosans 

 by steers, pigs, sheep, and a horse. The coefficients of digestibility varied within 

 rather wide limits with the different animals and in different experiments with the 

 same animals, but on an average this constituent was quite thoroughly digested. As 

 shown by the experiments reported the digestibility of pentosans is parallel to and 

 varies directly with that of carbohydrates. 



The fate of pentosans (xylans) in the animal body, B. Slovtzov (Izv. Imj>. 

 Akad. Nauk [Bo/. Acad. Imp. Sd. St. Peter ■slurg], 5. ser., 15 (1901), pp. 423-434; abs. 

 in Zischr. Untersuch. Nahr. u. GenussmtL, 8 {1904), No. 2, p. 157). — From experiments 

 witli separated ferments and with guinea pigs, the conclusion was drawn that when 

 xylan is consumed by herbivora in small quantities a portion at least is resorbed and 

 serves as a nutrient. The digestive ferments did not act upon xylan, but hydro- 

 chloric acid changed some of it into xylose. 



Concerning the resistance of true albumin to tryptic digestion in the animal 

 body, S. Kosexberg and C. Oppenheimer (Beitr. Chan. Physiol, u. Pathol., 5 {1904), 

 No. .'', /*/*. 412-421). — Erom experiments with a dog with a fistula carried on in con- 

 tinuation of earlier work" the conclusion was reached that in the body as well as in 

 vitro true albumin is resistant to the action of tryptic ferments. 



Concerning the influence of alkalis on protein metabolism, E. Dufourt 

 (Jour. Physiol et Path. Gen., 6 {1904), No. 3, pp. 489-496).— Experiments with dogs 

 on a meat and on a vegetable diet are reported, the alkali studied being bicarbonate 

 of soda in varying doses. According to the author the alkali increased the urea 

 excretion as compared with the total renal nitrogen both on a vegetable and on a 

 meat diet. The experiments are discussed at some length. 



Sweet clover as a stock feed, G. H. Otis {Breeder' ■■< Gaz., 46 {1904), No. 2, p. 54). — 

 ( 'ontrarv to the general opinion, the author on the basis of experience considers sweet 

 clover hay a satisfactory feed for farm animals, including horses and mules; however 

 he recognizes the fact that it is necessary to first accustom them to its use. In his 

 opinion it should be cut early and handled like alfalfa. The value of sweet clover 

 for binding soil on washed-out and abandoned limestone lands is also spoken of. 



On the distribution of osseomucoid, C. Seifert and W. J. Gies (Amer. Jour m 

 Physiol., 10 (1903), No. 3, pp. 146-148). — Experiments with mammals, birds, reptiles, 



a Beitr. Chem. Physiol, u. Pathol., 4 (1903), p. 279.
