872 EXPEEIMENT STATION EECORD. 



From the foregoing experiments it is concluded that self feeders are advan- 

 tageous; that a heavy 2- or 4-rov5'ed barley is preferable for feeding purposes 

 to a light 6-rowed barley ; and that in general it will not pay to reduce a good 

 quality of alfalfa hay, although it is recognized that reducing alfalfa increases 

 the feeding value of an ordinary grade from 15 to 25 per cent. 



Plans of self feeders and of feeding yards are included. 



Breeding lambs for fur, H. D. Smith (Farm and Ranch, S2 (1913), No. 36, 

 pp. 1, 2, figs. 6). — An account is given of extensive breeding operations being 

 carried on in Kansas in crossing American Lincoln ewes with the fur-bearing 

 caracul rams from Asia. 



Three kinds of fur are obtained from these crosses, i. e., first grade or Persian 

 lamb, if the curls are small and very tight; second grade or Astrakhan, if the 

 curls are leoser ; and third grade or Krimmer, when the fur is streaked with 

 gray. The hybrids resulting from this cross are said to be very hardy, with- 

 standing both drought and cold, and excellent rustlers. It is believed that 

 Cotswold, Leicester, and Wensleydale ewes can be used with as satisfactory 

 results as the Lincolns. 



Docking and castrating lambs, H. Hackedorn {Missouri 8ta. Circ. 61, pp. 

 207-210, figs. 2). — This circular describes the knife and hot pincers methods of 

 docking lambs and a common method of castrating. 



Dalgety's annual wool review for Australasia {Dalgetifs Ann. Wool Rev. 

 Austral., 1912-13, pp. 102, pi. 1). — This publication gives a complete summarized 

 account of the commercial wool industry in the markets of Australasia, with 

 references to the markets of Europe and America. The topics included are 

 market record, character of the clip, the producers' and buyers' positions, 

 demand and distribution, American demand, American tariff, trade with the 

 East, wool production estimates and the wool outlook, wool-selling methods, 

 preparation of cUp, excellence of Australian wools, competitors, wool substi- 

 tutes, and other related subjects. 



Productive swine husbandry, G. E. Day {Philadelphia and London, 1913, 

 pp. X+330, pis. 2, figs. 70). — This is a popular work dealing with the breeds of 

 swine, the results of swine-feeding experiments, and the care, management, and 

 marketing of swine, together with building specifications and directions. 



Ration experiments with, swine, 1908—1911, G. E. Morton {Colorado Sta. 

 Bill. 188, pp. 20, figs. S).— Continuing previous work (E. S. R., 24, p. 269), 6 lots 

 of 10 head each of 4S-lb. pigs were fed in 1908 and 1909 for a period of 14 weeks 

 on various proportions of corn and selected tankage and corn and fertilizer 

 tankage. The gains made apparently justified the use of the lower-priced fer- 

 tilizer tankage as compared with the selected material. The feedins; of corn, 

 barley, and selected tankage 3:3:1 proved slightly more expensive per 100 lbs. 

 gain than did a ration composed of corn and selected tankage 6 : 1. The feeding 

 of corn and shorts 2 : 1 produced less gain and at a somewhat higher cost per 

 pound of gain than the corn and tankage ration. 



In 1909 and 1910, 10 lots of 10 head each of approximately 175-lb. pigs were 

 fed for a period of 8 weeks on various proportions of California feed barley 

 with selected tankage, fertilizer tankage, shorts, corn, alfalfa hay, or sugar 

 beets, and 1 lot on winter rye. The best ration in the series proved to be one 

 consisting of California feed barley and corn 1 : 1, with alfalfa hay ad libitum, 

 the hay being fed whole in racks. This ration cost 4.83 cts. per pound of gain. 

 A ration of California feed barley and fertilizer tankage 9 : 1, costing 5.05 cts. 

 per pound of gain, was second in economy and preferable to rations composed 

 of either 7 or 5 parts barley. A ration of barley and alfalfa hay alone vrithout 

 com cost 5.06 cts. per pound of gain, and a ration of barley and sugar beets
