1919] ANIMAL PRODUCTION. 367 



The modified Wolff-Lehmann feeding standards, F. B. Morrison (Avicr. 

 Soc. Anhu. Prod. Proc. 1915, pp. 64-69). — After a discussion of liie limitations 

 of feeding standards and the necessity of modifying the Wolff-Lehmann stand- 

 ards, suggested modifications are presented which have since been embodied in 

 Table V of the appendix to Henry and Morrison's Feeds and Feeding (E. S. R., 

 34, p. 261). 



Nitrogenous constituents of feeding stuffs, H. S. Grindley {Amer. Soc. 

 Anim. Prod. Proc. 1916, pp. 133-141). — The analytical data on the amino-acid 

 content of blood meal, tankage, skim milk, wheat, barley, oats, corn, white soy 

 beans, cottonseed meal, and alfalfa hay published by Grindley and Slater 

 (E. S. R., 34, p. 412) are reprinted, and a general discussion is given as to the 

 value of such determinations in feeding investigations. 



Concerning corn as a source of protein and ash for growing animals, A. G. 

 HoGAN (Amer. Soc. Anim. Prod. Proc. 1916, pp. 221-232). — This contribution 

 from the Kansas Experiment Station presents without essential modifications 

 the material in a publication by the author previously noted (E. S. R., 37, 

 p. 164), with an added section reporting the observation that a pair of rats 

 kept on a ration of corn and ash consistently ate their young (.5 litters) until 

 the diet was changed. Parturition was difficult during the corn-feeding period. 



Utilization of apple pomace for animal feeding, G. AVarcolliee and H^diard 

 (Vie Affr. et Rurale, 8 (1918), No. 1, pp. 11, 12). — Suggestions are given for the 

 use in animal feeding of fresh, ensiled, and dried pomace. Pi'oximate analyses 

 of four samples of the latter are published. 



[Analyses of] unusual feeding stuffs, A. E. Vinson and C. N. Catlin (Ari- 

 i:ona Sta. Rpt. 1917, pp. 477, 478). — Proximate analyses are given of samples of 

 Tucca elata, sword beans (Caimvalia ensiformis), alfalfa hay, alfalfa straw, 

 tepary-bean hay, sorghum refuse, milo maize head chop, and wheat bran. The 

 protein content of other samples of wheat bran, of shallu whole grain, and of 

 cotton-stalk hurds is also noted. 



Weights of typical Shorthorns, .T. L. Tormey (Breeder's Gas., 75 (1919), No. 

 24, pp. 14O8, 141O). — A table is presented showing the average weights and the 

 range in weights by age groups of breeding animals of the Shorthorn breed 

 exhibited at the International Live Stock Expositions of 1908 and 1910. 



Investigations with growing steers, T. L. Haecker (Amer. Soc. Anim. Prod. 

 Proc. 1916, pp. 169-173). — In continuation of work at the Minnesota Experi- 

 ment Station previously mentioned (E. S. R., 82, p. 99) and published else- 

 where,* the author reports the individual slaughtering data of 5 calves killed 

 at the weight of 100 lbs. and 5 killed at 400 lbs., together with the average 

 for each group of the water, protein, fat. and ash content of the several tissue 

 components of the carcasses. 



More grass to make more beef, F. D. Faerell (Breeder's Gas., 75 (1919), No. 

 15. pp. S.'il. 8-'i2). — A consideration of some of the problems of grassland man- 

 agement, \\ith particular reference to the native pastures of Kansas. 



The utilization of grain sorghums in meat production, W. A. Cochel (Amer. 

 Soc. Anim. Prod. Proc. 1915, pp. 9-14). — The folio-wing feeding trials at the 

 Kansas Experiment Station are summarized: (1) Experiments in wintering 

 beef calves and cows on Kaflr corn silage or fodder with a protein supplement, 

 reported in Bidletin 19S (E. S. R., 32, p. 68) ; (2) a comparison, apparently not 

 elsewhere published, of ground corn, ground Kafir corn and hominy feed for 

 fattening steers, with sweet sorghum silage as roughage; and (3) the hog- 

 feeding tests given in the report of the station for 1915 (E. S. R., 36, p. 167).
