ANIMAL PRODUCTION. 369 



with 3 ewes and their 5 lambs sliowing that turnips may malve a profitable 

 sheep feed under the agricultural conditions of eastern Norway. 



Fertility in Scottish sheep, F. H. A. Marshall (Trans. Highland and Agr. 

 Soc. Scot., 5. scr., 20 (IfiOS), pp. 139-1.51). — A series of statistics based upon 

 inquiries made by sheep breeders was compiled by the author for the purpose of 

 showing some of the principles involved in determining fertility in sheep. The 

 percentage of lambs per 100 ewes and the percentage of barren ewes in various 

 flocks of different breeds and kept under diffei'ent conditions are show^n in 

 tabular form. It was found that certain changes of weatlier during the breed- 

 ing season may have an unfavorable effect upon the percentage of lambs and 

 that the practice of flushing ewes almost invariably has the effect of increasing 

 the percentage of twin lambs and triplets. Considerable evidence was obtained 

 to show tliat a high fertility is ordinarily hereditary. 



Caracul sheep, E. Meuleman (Le Motif on Karakul. Brussels, 1908, pp. 

 20, figs. S). — An account of raising Persian, caracul, and similar sheep which 

 yield the fur known as Persian lamb, broadtail, astrakhan, etc. The author 

 believes that raising such sheep might be advantageously carried on in parts of 

 Belgium. 



Caracul sheep and their possible use in the sandy regions of Germany, 

 J. KtJHN (IIIKS. Landio. Ztg., 28 (1908), No. 2J,, pp. 213, 21), figs. .J).— The 

 author does not believe that caracul sheep would be suited to German condi- 

 tions, as they apparently require their usual environment in order to produce 

 lambs with the cliaracteristic pelts. 



Raising and fattening calves on skim milk with and without supplement- 

 ary feeds, P. DoRKic and P. Daire (Indus. Lait. [Paris], 33 (1908), No. 10, 

 pp. 183— ISl). — Barley flour, rice flour, and linseed oil were used as supple- 

 ments to skim milk and in the tests which are briefly cited the calves gained 

 from 0.6 to 1 kg. per head per day. The addition of oil to the ration did not 

 materially improve the quality of meat nor influence the gains in weight. 



Beef production. II, Methods of beef production in Indiana. Ill, Factors 

 influencing the value and cost of feeders, J. H. Skinner and W. A. Cochel 

 {Indiana Sta. Circs. 12, pp. 32; l-i, pp. 23, figs. 22). — Circular 12 is a summary 

 of replies received from 929 successful feeders of Indiana to a list of 100 ques- 

 tions submitted relative to the extent of the business of feeding cattle, the 

 equipment used, and the methods of feeding in vogue. Circular 14 discusses 

 the conformation, quality and breeding, age, condition and weight of steers, 

 market conditions, and other factors influencing the value and cost of feeders. 



Fifty years among Shorthorns, R. Bruce (London, 1907, pp. 21.'i, pis. 21).— 

 On the basis of personal knowledge the author describes a very large number 

 of notable Shorthorn animals of Great Britain. 



Congo cattle, E. Meuleman (Le Detail du Congo, Brussels, 1907, pp. 23, 

 figs. 13). — A summary of data on the zebras and the cattle in the Congo. The 

 advantages of introducing improved breeds of cattle and related questions are 

 considered. 



Inverted starch in pig feeding, S. S. Sevenster (Milch Ztg., 37 (1908), No. 

 8, p. 88). — A brief note on the use of diastasoliu for inverting starch. The use 

 of smaller amounts than usual of the ferment is to be preferred, according to 

 the author's experience. 



Supplements to corn for fattening hogs in dry lot, J. H. Skinner and W, A. 

 CociiEL (Indiana Sta. Bui. 126, pp. 11(3-159). — Tankage, linseed meal, and soy- 

 bean meal were compared as supplements to corn meal for fattening hogs. The 

 tests were conducted at different seasons of the year with hogs of various ages 

 and conditions of finish. The results are shown in the following table :
