Comparative effects of meat meal and fish meal in swine feeding experi- 

 ments, A. Kleemann (Landw. Vers. Stat., 13 (.1910), No. 1-3, pp. 187-219).— 

 Basal rations of steamed potatoes, potato chips, potato flalies, maize, and phos- 

 phate of lime were fed to 6 lots of 4 swine each. The supplementary rations 

 compared were meat meal, fish meal rich in fat, and fish meal poor in fat. 

 Starch was added to the latter ration in order to equalize the amounts of 

 digestible protein and starch values. 



In a period lasting 99 daj's 2 groups receiving the meat meal made an average 

 daily gain per head and day of 0.513 kg., at a cost of 0.172 mark per kilogram 

 (about 4 cts. per pound), and 0.462 kg. at a cost of 0.1838 mark per kilogram, 

 respectively. The 2 lots receiving starch and fish meal deficient in fat made 

 an average daily gain per head and day of 0.511 kg. at a cost of 0.3157 mark 

 per kilogram, and 0.531 kg. at a cost of 0.352 mark per kilogram, respectively. 

 The corresponding figures for the lots receiving fish meal rich in fat were 

 0.525 kg. at a cost of 0.2796 mark per kilogram, and 0.563 kg. at a cost of 

 0.2644 mark per kilogram. The feeds were estimated at the following prices 

 per 100 kg. : Steamed potatoes 3 marks, potato chips 13 marks, potato flakes 

 15 marks, maize 16.9 marks, meat meal 26.5 marks, fish meal 26.8 marks, starch 

 20 marks, and phosphate of lime 13.8 marks. Analyses of the feeds are given. 



The animals in one lot on meat meal.were off their feed toward the close of the 

 test, and hence made considerably lower gains than the other lots. The flesh 

 of all the experimental animals was considered of good quality. Samples of 

 flesh taken from the back showed no essential difference in the Reichert-lNIeissl 

 number or in the melting point, but the iodin number was higher in the fish-fed 

 animals, particularly those fed fish meal rich in fat. 



Feeding hogs in the South, D. T. Gray (U. »S'. Dept. Agr., Farmers' Bui. 

 Jfll, pp. -'/?. fiffs. 9). — This publication, replacing Farmers' Bulletin 100 (E. S. R., 

 11, p. 381) was written to furnish information of a practical nature for the 

 benefit of those engaged in swine production in the Southern States. The breeds 

 of swine are briefly described, and illustrations are given of 3 types of portable 

 hog houses. The use of dairy by-products and other supplements are discussed, 

 and a large number of feeding tests made at the state stations are cited. Evi- 

 dence is presented in support of the argument that hogs can not be profitably 

 raised on corn alone. 



The advantages of using pasture are summarized as follows: "Pork costs 

 only one-third to one-half as much when pastures are used as when concentrated 

 feeds alone are used. The soils are improved very materially as a result of 

 growing the legumes for the hogs and feeding extra grains to the animals. 

 The crops are harvested (through the hogs) without danger of loss from rains 

 and without expense. The hogs are under favorable health conditions ; there- 

 fore losses from disease will be lessened." 



Preservation of beet pulp by lactic ferments, Ij. Malpeaux (Betterave, 20 

 {1910), No. 513, pp. 291-294; Sucr. Indig. et Colon., 16 {1910), No. 13, p. 292- 

 296). — Directions are given for using a commercial ferment (lacto-pulpe), with 

 which the beet pulp is inoculated when put into the silo. A brief report is 

 made of investigations on the chemical changes which take place in the ensiled 

 pulp. 



Methods of computing rations, A. Kraemer (Lainhv. Jahrb., 39 {1910), 

 No. 3, pp. 439-Ji59, fig. 1). — Illustrations are presented of a method of computing 

 rations for live stock, based on the valuation of dry matter, protein, and the 

 starch values of Kellner.
