tion, 6.5 lbs. of skim milk per pouud of gain, but made the most economical 

 gains. The addition of protein-rich feeds as a supplement to ground barley 

 effected a considerable saving in the amount of grain required per pound 

 of gain. 



Successful experiments are reported in feeding roots, particularly mangels, 

 to brood sows, from 15 to 20 lbs. of raw mangels and 1 lb. of grain being fed 

 daily. The results of hogging off mangels, ruta-bagas, kale, and rape are 

 given, as furnished by a private farm in Washington. The hogs relished the 

 mangels best, the ruta-bagas being eaten less readily. The hogs did not do so 

 well on rape as they did on kale, but this was thought to be due to the dried 

 condition of the rape. 



The hogs on half rations of ground barley ate much larger quantities of 

 roots and forage than those on a full ration, though they made only about 

 half as large gains. Two lots of hogs on the mangels had the same acreage 

 each and the same tonnage of mangels, approximately, but those on the half 

 rations of grain had their mangels all eaten in 19 days, while the full-ration 

 hogs were put back on their field again and required 11 days longer to clean 

 up all their mangels. All the hogs on full feed were in good condition for 

 slaughter at the conclusion of the experiment ; the others were not. 



Swine feeding' experiments comparing skim milk, blood-grain meal, and 

 fat-free fish-feed meal for young swine, Klein {Milchw. Zentbl., 44 (1915), 

 No. 6, pp. 81-86). — Three lots of pigs fed a basal ration of skim milk, barley, 

 barley bran, and potato flakes, lot 2 receiving a blood-grain feed, and lot 3 fish 

 meal in addition, made average daily gains per head per day of 0.397, 0.379, and 

 0.37 kg., demonstrating that these supplementary feeds have little value when 

 skim milk forms a part of the basal ration. 



Successful swine rations for the corn belt, J. M. Ewakd and W. H. Pew 

 (Iowa Sta. Circ. 26 (1916), pp. 3-15, figs. 8). — This circular gives suggestive 

 rations for fattening hogs, breeding sows, and suckling sows under both dry- 

 lot and forage-feeding conditions. 



Stallion enrollment. — IV, Report of stallion enrollment work for year 

 1915 with lists of stallions and jacks enrolled, H. E. McCartney (Indiana 

 Sta. Circ. 53 (1916), pp. 238, pi. 1). — This is a report of stallion enrollment work 

 for the year 1915, with lists of stallions and jacks enrolled. 



Spotted asses, A. E. Jenks (Jour. Heredity, 7 (1916), No. 4, pp. 165-168, figs. 

 2). — It is stated that while piebalds are common among most domesticated ani- 

 mals the ass, like the camel and elephant, rarely has spots. However, in- 

 stances of the kind are cited and it is thought that selective breeding is largely 

 responsible for this albinism. 



Bacterial infection of hen's eggs, A. Postolka (Wiener Tierdrztl. 

 Monatsschr., 3 (1916), No. 1, pp. 3-11).— Out of 144 eggs examined 35 were 

 found to be bacterially infected. The principal bacteria found were Bacillus 

 mescntericus vulgatus, Staphylococcus pyogenes aureus, B. subtilis, and B. 

 megatherium. 



Care and management of baby chicks, Mr. and Mrs. G. R. Shoup (Wash- 

 ington Sta., West. Wash. Sta., Mo. Bui., 3 (1916), No. 12, pp. ii-16).— General 

 methods for handling baby chicks for the first eight weeks are given. 



DAIRY FARMING— DAIRYING. 



The succulent feed supply, E. B. Stookey (Washington Sta., West. Wash. 

 Sta., Mo. But., 3 (1916), No. 12, pp. 8-11). — Five plans for supplying succulent 

 feed for the dairy farm the year round are given. In two of these the silo is
