ANIMAL PRODUCTION. 569 



The principles and practice of feeding, including our available stock foods, 

 W. II. Dalrymple {Louimma fitas. Bui. 115, pp. 3-63, figs. 12). — This is u 

 bulletin of general iuformation on the principles of stock feeding- Many ex- 

 amples of rations for different kinds of stock are given, with special reference 

 to the utilization of molasses, rice by-products, cotton-seed meal, Lespedeza hay, 

 and other feeding stuffs which can be economically raised iu Louisiana. The 

 data with reference to the feeding of blackstrap molasses are based in pnrt on 

 replies receivixl from a number of the large planters to a circular of inquiry 

 as to their experience. 



Analyses of registered feeding stuffs, J. T. Willard et al. {Kansas Sta. 

 Bui. loS, pp. 91-l.'f2, fig. 1). — This bulletin gives a summary of the history of 

 the feeding stuffs law and its administration, together with the amended law in 

 full, and an exposition and explanation of the requirements of the law and the 

 rulings made under it. Analyses of a great variety of feeds as made under the 

 amended law are also reported. 



The inspection shows that in general the feeds were fairly up to the guar- 

 anties. Most of the deficiencies were with corn chop, for which a guaranty is 

 no longer required. The samples varied according to the region in which the 

 feed was produced, and from a study of the different regions it appears that 

 the protein content tends to become higher the farther West the feed originates. 



Analyses of commercial feeding stuffs sold in Maryland, H. B. McDon- 

 nell ET AL. {Md. Agr. Col. Quart., 1909, No. Jf^, pp. 7). — ^Analyses are reported 

 of cotton-seed, linseed, germ oil, corn, meat, and bone meals, gluten feeds, malt 

 sprouts, dried brewers' grains, wheat bran and middlings, ground oats, oat 

 straw, oat hulls, and corn hulls. 



Alfalfa feeds, G. M. MacNider (N. C. Dept. Agr., Div. Chern. Circ. 1, pp. ^). — 

 Analyses of alfalfa meal and mixed alfalfa feeds are reported. 



Denaturing feeding barley {Illiis. Landiv. Ztg., 29 (1909), No. 46, pp. W, 

 4-'fl, figs. 6 ) . — This article describes a cheap and efficient method for denaturing 

 with eosin barley which is imported for feeding purposes. 



The American industry of corn products, T. B. Wagner {Jour. Soc. Chem. 

 Indus., 28 {1909), No. 7, pp. 3^3-348, fig. 1).— After a brief account of the 

 history of the corn industry in America, the author describes the process of 

 manufacturing corn oil, gluten meal, gluten feeds, starch, corn sirup, glucose, 

 and other products of the corn kernel. 



The use of waste products of vineyards as feeds for live stock, U. Rossi 

 {Agr. Mod., 15 {1909), Nos. 21, pp. 282-284; 22, pp. 296-298; 23, pp. 311-313, 

 fig. 1). — ^Analyses of vinasse and grape marc are given and their use as stock 

 feeds is discussed. 



Tapioca flour for raising calves, A. Gouin and P. Andouard {Bui. Soc. Nat. 

 Agr. France, 68 {1908), No. 10, pp. 776-779; Bui. 8ta. Agron. Loirc-Inf., 1907-S, 

 pp. 81-84). — The authors found the nutritive value of tapioca flour about equal 

 to that of potato starch when used as a supplementary feed with skim milk. 



Lamb feeding for 1908-9, A. D. Faville {Wyoming Sta. Bui. 81, pp. 3-8, 

 figs. 2). — An experiment is reported which was made for the purpose of testing 

 the value of Wyoming-grown grains for fattening purposes. Three lots of 3.5 

 sheep each were fed for 91 days on alfalfa of rather poor quality and equal 

 amounts of grain. With the different grains the average daily gains per head 

 were as follows: Corn 0..3 lb., emmer 0.2.3 lb., Scotch barley 0.33 lb. In each 

 lot 17 of the sheep were of the Rambouillet type. The rest were crosses of 

 Down sires with grade Merino dams. In each case the mutton grades made 

 more raiTid gains than the Rambouillet.
