ANIMAL PRODUCTION. 475 



The history of the development of the different breeds of cattle in Bavaria, 

 Attinger (Deitt. Lamlw. Tierzucht, 15 {1911), lYos. 19, pp. 221, 222; 20, pp. 

 233, 23-'/). — A historical account of improved methods of breeding, and of the 

 influence of introduced breeds of cattle. 



Feeding sheep and lambs: Clover hay v. native hay; turnips v. dry 

 ration, T. R. Arkell {New Hampshire Sta. Bill. 152, pp. 3-19, figs. 6). — This 

 reports the results of feeding tests conducted during 1909-10 to test the rela- 

 tive feeding values for sheep of (1) clover hay v. the ordinary hay mixture of 

 very variable composition and designated native hay, grown in New Hampshire, 

 and (2) turnips in conjunction with grain and hay v. a dry ration of grain 

 and hay. 



In the first experiment 4 lots of sheep were used, five in each lot, 2 lots 

 consisting of ewe lambs of the mutton breeds, and the others of 2 to 3-year-old 

 ewes, either Rambouillets or the ordinary grade stock of New Hampshire. 

 Both lots of lambs were fed an equal quantity of a mixture of corn, bran, and 

 oats (equal parts by weight) and turnips. In addition one lot was fed clover 

 hay, the other an equal quantity of native hay. With the aged ewes the same 

 plan was followed with the hay, but they were fed only turnips besides. 

 Analyses of all the feeds and digestion coefiicients of the native hay are 

 reported. 



The lambs fed clover hay made an average daily gain of 0.351 lb. per lamb 

 at a cost of 7.66 cts. per pound; those fed native hay, 0.229 lb. at a cost of 

 12.4 cts. The corresponding figures for the aged ewes were 0.184 lb. at a cost 

 of 16.24 cts.. and 0.065 lb. at a cost of 42.87 cts.. respectively. The poor results 

 with native hay were due to the fact that it contained large quantities of 

 timothy and other grasses that the sheep did not relish. Farmers are advised 

 to sell their timothy and native hay and purchase for their sheep clover or 

 alfalfa hay. 



In the second test 10 ewe lambs of the mutton breeds were divided into two 

 lots. Lot 1 was fed grain (oats, bran, and corn in equal parts by weight) and 

 clover hay ; lot 2, the grain mixture, clover hay, and turnips. The amount of 

 grain and clover hay given to lot 2 was so reduced that the cost of the ration 

 would equal that of lot 1. Lot 1 made an average daily gain per lamb of 0.29 

 lb. at a cost of 11.96 cts. per pound ; lot 2 a daily gain of 0.378 lb. at a cost of 

 9.60 cts. The results of this experiment were very striking. In every instance 

 the turnip-fed lambs made decidedly better gains than those fed the dry ration. 

 This was especially apparent toward the end of the test. The difference is 

 attributed to a stagnation of the appetite of those fed the dry ration. " The 

 turnip-fed lambs eagerly sought and would have eaten more." 



The pig, F. Faelli {II Porco. Milan, 1911, pp. Jf61; rev. in Vet. Jour., 67 

 {1911), No. J,31, pp. 311, 312).— K pioneer work on the breeds, breeding, feeding, 

 and management of swine from the Italii'.ii point of view. 



Is German meat meal a good feed for swine? M. Popp, W. Felling and F. 

 ScHtJTZE {Dent. Landw. Presse, 38 {1911), Nos. 37, pp. ^29, 430; 3S, pp. 41,0, 441, 

 figs. 4). — Meat meal proved to have about the same value as fish meal when 

 used as a supplement to barley and in mixed rations for swine. It was supe- 

 rior to a proprietary mixed feed or to a ration composed entirely of barley. 

 Analyses of feeds and results of slaughter tests are given. 



The conditions underlying the breeding of Percherons, and a comparison 

 of their form with the Boulonnais and Belgian breeds based on official 

 measurements, W. Gotzmann {Landw. Jahrb., 40 {1911), No. 1-2, pp. 1-81, pis. 

 3). — This treats of the origin, characteristics, and geographic distribution of 

 the Percherons. Measurements of 515 Percherons are presented in tabular form.
