AXIMAL PRODUCTION. 1065 



" I'ho two eci'eals omnier (TiUicum diroccum) and einkorn (Triliciiin vkjiio- 

 coccum) belong to the same group as the oats and like it are characterized by 

 high protein and relatively low carbohydrate. They have a lower intrinsic 

 fodd value than the other grains, but a narrow nutritive ratio and consequently 

 are muscle or energy producers. In ffiod value they are nearly the same as 

 (lats. and their "cultivation where oats can not be grown is to be advocated. 



"The two cereals proso or broom-corn millet ( J'dnicuiii niilidcciuti) and the 

 iionsaccharine sorghum (Andropoffoii sorghum) belong to the maize group, and 

 though lower in food value than maize itself they equal the oat group. They 

 are of great imi>ortance when maize can not be grown and when there is need 

 for a high carbohydrate and heat or fat producing food. 



" P.arley and rye belong to the wheat group and are nearly equal to it in food 

 value." 



Modern views concerning' the food requirements of farm animals and 

 the principles of rational feeding-, N. IIanssox (Xord. Mrjcri Tidn.. ,?.? ( IDOS). 

 Vo.s. .'i2, PI). -'i0.j-.'i97 : //.?, pp. 50S, .'kOD ; .',.',. pp. 520-.')22). — An address which dis- 

 cusses the results of recent studies conducted by Kellner, the Copenhagen Ex- 

 lieriment Station and others, of feeding problems and the nutritive effect of 

 (litferent food comp<jnents. The author has crystallized his deductions into 

 feeding standards showing the amounts of digestible protein and total feed 

 units (1 "feed unit" equaling O.G starch value) required per head daily under 

 varying conditions, in the case of dairy cows, fattening steers, young cattle, 

 working oxen and horses, and fattening and breeding swine. 



The mineral elements in animal nutrition, E. R. Fokp.ks (Ohio fita. Bui. 

 201, pp. 129-172). — This is an important snnnnary of available data. The main 

 facts regarding the function of the mineral elements in animal nutrition are 

 piesented in such manner as to serve the student of agriculture as an intro- 

 duction to this important subject. 



Commercial feeding- stuffs, E. II. .Jenkins and .J. P. Street (CoiiHcrticiii 

 i<ttitr i^ta. Rpt. 1!)()7-S, pi. UK pp. 7l7-7(i2). — The 218 samples of feeding stuffs 

 analyzed under the State law and Ti.^) samples sent by individuals included cot- 

 ton-seed and linseed meals, wheat bran, middlings, and feeds, maize meal, maize 

 for ensilage, gluten feeds, hominy feed, rye, buckwheat, flax and barley products, 

 distillers' and brewers' grains, spent hops, dried beet pulp, meat scrap, proprie- 

 tary stock and poulti'y feeds, mixed feeds, and miscellaneous materials. Nine 

 brands of gluten feed contained artificial coloring matter. The acidity of the 

 gluten feeds is reported as determined with different indicators, the results 

 being lf)west with litnnis, and considerably higher with plienoli)hthaleiu and 

 Toejtfer's reagent. Several pr()i)rietary feeds were found to contain large quan- 

 tities of we(Ml seeds, one brand of flax feed, costing $2.") per ton, containing 

 S(j,fH»0 wccfl seeds per jxunid. 



Commercial feeding- stuffs in 1907-8, .1. W. Carson and C. S. Fhaps (Tr.ra^ 

 i<ta. /{III. 117, pp. .5-67). — This bulletin contains the text of the State feeding 

 stuffs law and reports and disc-usses the results of the first year's operation. 

 Analyses are given of 1,042 sanqiles of feeding stuflfs, which Included cott(m-seed 

 meal and cakes, wheat bran, shorts and choi)s, rice polish, bran and hulls, corn 

 chops, crushed ears and bran, Kafir corn i-hojis. milo m:rize chojjs. and mixed 

 feeds. A list of the jtrovisional standards and definitions is included. 



Concentrated commercial feeding stuffs, A. Mr(Jii.i, ( Lah. Inlaiul A'rr. /)r-/)/. 

 \('iiii<i(l(i^ Hill. !.')<!. ]tp. 2(i). — This bulletin contains analyses of bran, middlings 

 or sliorts. linseed meal, cotton-seed meal, chopped feed, and other concentrated 

 feeding stuff.s.
