578 EXPERIMENT STATION RECORD. 



[Feeding experiment with winter-fed lambs], H. H. Wing (New York 

 Cornell Bui. 285, pp. 40-.'i6, flgs. 2). — This reports an experiment to determine 

 the relative cost of gain in weight with wide and narrow rations, and to study 

 the effect of overfeeding. The experimental animals consisted of 3 pens of 

 feeding lambs. In addition to wheat salvage and corn, which was given to all 

 the lambs, lot 1 was given alfalfa hay, bean fodder, and oil meal ; lot 2 alfalfa 

 and ajax flakes (distillers' dried grains) ; and lot 3 timothy hay as a supple- 

 mentary feed. 



At the end of 60 days the lambs in lot 1 (nutritive ratio 1: 5) had made an 

 average gain of 16.3 lbs., at a cost of 8.27 cts. per pound gain. The correspond- 

 ing figures for lot 2 (nutritive ratio 1 : 4.6) were 20 lbs. gain, at a cost of 7.48 

 cts. per pound, and for lot 3 (nutritive ratio 1:8) 15.3 lbs. at a cost of 7.87 cts. 

 per pound. 



" The rations with nutritive ratios of 1 : 5 and 1 : 4.6 gave much better results 

 than the one with a nutritive ratio of 1:8. The experience with pen No. 3 

 goes to show that these sheep lacked protein in their ration. The sheep in this 

 pen showed this, (1) by being very eager to eat up all the bean forage, and (2) 

 by coming back up to full feed after their ration had been changed toward the 

 end of the experiment when many lambs in pen No. 3 were eating daintily or 

 were off feed entirely. . . . Pen No. 3 not only made poorer gains but it was 

 hard to get the lambs to eat as much grain by weight as did the lambs in 

 pens 1 and 2, until a change was made in the ration which narrowed the nu- 

 tritive ratio." 



A discussion of overfeeding as the cause of apoplexy is noted on page 588. 



Report of the wool specialist, J. A. Hill [Wyoming Sta. Rpt. 1910, pp. 

 65-67). — A brief report of work in progress which consists mainly of a study 

 of the variability in the breaking strain of wool fibers. A new experiment in 

 studying the effect of environment on quality and quantity of wool has been 

 imdertaken. The shrinkage of wool in scouring in samples sent in from 21 

 firms ranged from 43.6 to 79.1 per cent. 



Annual wool review (Bui. Nat. Assoc. Wool Manfrs., J/O (1910), No. Ji, pp. 

 301-352, pi. 1, chart 1, map 1). — An estimate of the domestic wool clip, exports, 

 and imports of wool in 1910. There is also a review of the wool industry, ac- 

 companied by many statistical tables concerning wool production in the United 

 States and foreign countries. 



Sheep breeding' in Scotland, K. Bitzek (Filhling's Landw. Ztg., 59 (1910), 

 No. 18, pp. 612-626, chart 1). — A general and statistical account of the sheep 

 industry in Scotland, with comments from a German point of view. 



On the present conditions of sheep husbandry, J. Natiiorst and T. Hofman- 

 Bang (K. Landthr. Akad. Handl. och Tidskr., J,9 (1910), No. 7, pp. 637-6J,Ji).—X 

 discussion of the conditions under which sheep husbandry can be made profit- 

 able in modern Swedish agriculture. 



Plan to promote sheep raising' in Russia, J. H. Snodgrass (Daily Cons, and 

 Trade Rpts. [U. 8.], IJf (1911), No. 12, p. 190).— A note on the efforts of the 

 Russian Government to encourage the sheep industry in those portions of 

 Siberia not well adapted for other branches of agriculture. 



The wild oriental sheep of Gmelin (Ovis orientalis), N. V. Nasonov (Isv. 

 Imp. Akad. Nauk (Bui. Acad. Imp. 8ci. St. Petcrsb.), 6. scr., 1910, No. 9, pp. 

 681-710, pi. 1, figs. 12). — A detailed description of the original cranium of a 

 Gmelin oriental ram, as described by Pallas in 1776, and which has been in the 

 museum of the Russian Academy of Science. Measurements of skeletons and 

 diagrams of cross sections of the horns of modern sheep now kept in the vicinity 

 of Ispahan are submitted to show the close relationship to 0. orientalis.
