176 EXPERIMENT STATION RECORD. [Vol. 41 



Report on commercial feeding stuffs, 1918, E. M. Bailey {Connecticut 

 State Sta. Bui. 212 (1919), pp. 353-395).— llejiort is made on samples of feeding 

 sstufCs collected by the station's agent during December, 1918, and January, 

 1919, and those submitted by the dairy commissioner and private individuals 

 during the year. Proximate analyses are published of cottonseed meal, cotton- 

 seed feed, linseed meal, wheat bran, wheat mixed feed, wheat middlings, rye 

 feed, rye middlings, barley feed, barley mixed feed, ground barley, corn gluten 

 feed, hominy feed, yellow hominy feed, corn feed meal, brewers' dried grains, 

 distillers' dried grains, dried beet pulp, velvet bean feed, peanut-oil meal, 

 copra cake meal, and various proprietary stock feeds, calf meals, and poultry 

 feeds. Reports on condimental foods and remedies are also included. 



The international trade in feeding stuffs {Internat. Inst. Ayr. [Borne], 

 Intcmat. Rev. Sci. and Pract. Agr., 7 (1916), No. 4, pp. ^67-510; 8 (1917), No. 4, 

 pp. Ji89-551). — Statistics are given following the plan previously noted (E. S. 

 R., 33, p. 664). They show the production, foreign trade of the various coun- 

 tries, and prices of residues of the milling, oil, sugar, and brewing and allied 

 industries, also of residues of animal origin. Extensive bibliographies are 

 Included. 



International trade in concentrated cattle foods, G. de Bkancion and E. 

 Van de Weyer (InteiTiat. Inst. Agr. [Rotne], Internat. Trade Concent. Cattle 

 Foods, No. 4 (191S), pp. 72). — The information noted above is published in an- 

 other form and according to a slightly different plan. 



Steer nutrition (Georgia Sta. Rpts. 1917-18, p. 13).— In the course of diges- 

 tion trials, it was found that the time required for feed residues to pass through 

 the alimenary tract of a steer varied from 2.9 to 5.2 days, finely divided ma- 

 terial being excreted in the shortest time. Rapidity of passage was associated 

 with lowered digestibility in the case of crude fiber. 



Range cow maintenance project on Russian thistle silage (New Mexico 

 Sta. Rpt. 1918, pp. 62, 63). — Silage made exclusively of Russian thistle was 

 found to have a disagreeable odor when fresh and to deteriorate rapidly upon 

 exposure to the air, but silage made from a mixture of Russian thistle and 

 corn meal (100:1) proved satisfactory and maintained the body weights of 

 ;1 range cows fed no other feed for 20 days. At the end of the test each cow 

 was eating about 40 lbs. per day. It is suggested that a few stalks of corn or 

 sorghum might be substituted for the corn meal. 



Milk ration for dairy calves (North Dakota Sta. Rpt. 1917, pp. 18. 19). — 

 It was found that a group of 4 calves, each fed 16 lbs. of skim milk and 1 

 lb. of boiled flaxseed per day, was essentially equal in thrift and general 

 development at the age of 6 months to another group fed 8 lbs. of whole milk 

 and 8 lbs. of skim milk per head daily. Both lots were fed whole milk ex- 

 clusively until 3 weeks old, and began to have grain added to the milk ration 

 when .5 weeks old. 



Quantity and composition of ewes' milk: Its relation to the growth of 

 lambs, R., E. Neidig and E. J. Iddings (Jour. Agr. Research [V. S.}, 17 (1919), 

 No. 1, pp. 19-32). — This paper from the Idaho Experiment Station furnishes 

 individual data for 18 ewes (3 typical specimens each from 6 breeds) as to 

 amounts of milk produced and its specific gravity and chemical composition on 

 tlie tenth, twentieth, thirtieth, fortieth, and fiftieth days after parturition and 

 the weights of the ewes and their lambs on these days. The amounts of milk 

 were determined by weighing the lambs before and after suckling. The milk 

 samples for analysis were secured by milking one side of the udder by hand 

 while a lamb suckled the other side. The breed averages for milk yield and 

 chemical comiuisition are summarized in the following table:
