EXPERIMENT STATION RECORD. 



determinations of betain, cholin, gossypein, organic acids, and several members of 

 the carbohydrate group. The principal conclusions follow: 



The average amount of lietain and cholin in 7 samples of cotton-seed meal is 0.28 

 per cent. The ratio of betain to cholin in 2 samples is 79:21 and 78:22. (xossypein, if 

 present, is in minute quantity. 



Of the nitrogen-free extract in 9 samples, 29.2 per cent is composed of pentosans, 

 and 47.4 per cent of ratlinose. The pentosans of cotton-seed meal are not soluble in 

 diastase, and are contained entirely in the nitrogen-free extract, unless an unusually 

 large (luantity of hulls is present. Cotton-seed meal contains no starch. No appre- 

 ciable quantity of sucrose or reducing sugars is present. 



Small quantities of organic acids are present, the average of 5 samples being 0.48 

 per cent. 



Concerning blood molasses, a ne-wr feeding stuff, F. Strohmer [Oesterr. Ungar. 

 ZtseJir. Ziickirhid. k. L<i)i<1h\, A'y [lUOO), p. lai; nhs. in Cfidhl. A(jr. Chem., 30 {1901), 

 No. 9, j)p. 596-698). — Molasses proved a valual)le addition to blood feeds, since it 

 improved the feeding value and acted as a preservative. Analyses of a number of 

 l)lood molasses feeds are reported. 



Analyses of feed stuffs sold in Maryland (Mar)/l<mdAffr. Col. (juart., 1901, No. 

 lii, pp. 2-19). — The State feeding-stuff law is quoted, and analyses reported of a num- 

 ber of samples of cotton-seed meal, flaxseed meal, pea meal, middlings, gluten feed, 

 germ-oil meal, gluten meal, mill feed, h(jminy chop, shipstuff, old-process oil cake, 

 bran, ground corn, corn fodder and hay, distillery grains, linseed meal, cereal 

 breakfast food by-products, mixed rations, and poultry feeds. Three samples of 

 insecticides were also examined. Brief directions are given for mixing rations, and 

 condiments and condimental feeds are discussed. ■ ^ 



Analyses of concentrated commercial feeding stuffs, H. J. Wheeler and 

 A. \V. Jjosworth (Rhode Jdand Shi. lUd. 77, pp. 173, 174)- — Analyses of 19 samples 

 of gluten meal, 1 of gluten feed, and 2 of linseed meal. 



Analyses of feeding stuffs, H. J. Wheeler and A. W. Bosworth {Rhode Island 

 Stii. Bid. 78, pp. 177-181). — In comi)liance with the State feeding-stuff law, analyses 

 were made of hominy meal, chops, damaged whole wheat, spring-wheat Ijran, winter- 

 wheat bran, middlings, cotton-seed meal, linseed-oil meal, gluten meal, animal meal, 

 oats, ground beef, beef scrap, and a number of commercial feeds for poultry and 

 stock, mostly ])y-products from the mamifacture of cereal breakfast foods. 

 • Feeding stuffs, A. Halencke and N. Klinc; {Jahre.^tter. Thai. Londu'. Kreis l>ns. 

 Slat. Sjiei/er, 1900, /ip..5-S). — A number of analyses of feeding stuffs and molasses are 

 reported. 



Digestion experiments witli Kansas feeds, J. T. Willard and R. W. Clothier 

 {Kansas Sta. Bnl. 103, pp. 253-275). — The (ligestil)ility of a number of feeding stuffs 

 was tested with steers, with the results shown in the table below. These included 

 alfalfa hay of different cuttings, Buffalo-grass hay, prairie hay, Katir-corn stover, 

 Katir-corn meal and soy-bean meal. Kafir-corn stover was fed with the last two 

 materials, the digestibility of the concentrated feeds alone being calculated.
