ANIMAL PRODUCTION. 1109 



fed mangels in addition to a grain ration (corn, oats, and linseed cake) there was an 

 average daily gain of 40.5 lbs. per sheep as compared with 33 lbs. when sugar beets 

 were fed with the same grain ration. The sugar beets eaten were grown on 0.909 

 acre and the mangel-wurzels on an acre. The cost of growing the latter was less than 

 the former. 



The test was repeated in 1901 with 2 lots of 16 sheep each, fed respectively niangel- 

 wurzels and sugar beets in addition to 1 lb. per head i)er day of oats, maize, and lin- 

 seed cake. In the 8 weeks of the test the sheep fed mangel- wurzels made an average 

 gain of 30 lbs. each, and those fed sugar beets of 22 lbs. "Moreover, tlie sheep which 

 had received mangolds handled better, and their wool looked brighter than in the 

 case of those receiving sugar beet. These results were, therefore, even more unfa- 

 vorable to sugar beet than those obtained in the trials of the preceding year."

On the gro-wth cf suckling pigs fed on a diet of skimmed cow's milk, 31. \ k- 

 OAKET B. Wilson [Amer. Jour. Physiol., 8{190'2), No. 3,j)p. 197-212). — In continua- 

 tion of previous work by L. C. Sanford and G. Lusk, which is noted in detail, the 

 author tested the comparative feeding value of skim milk with and without the addi- 

 tion of dextrose and lactose. Six new-born pigs of the same litter were obtained. 

 Three were slaughtered and analyzed, and each of the rations tested was fed to one 

 of the 3 remaining pigs. In the 16 days of the test the pig fed skim milk made a 

 total gain of 883 gm.; that fed skim milk with 30 gm. of lactose hydrate per liter 

 gained 1,140 gm., and the pig fed skim milk with the same amount of dextrose gained 

 98(5 gm. At the close of the test the pigs were slaughtered and analyzed. Below is 

 the autlior's summary of this test and the earlier one referred to above: 



"Skimmed cow's milk, with or without 2 to 3 per cent of added lactose or dex- 

 ti-ose, is normally absorbed by suckling pigs. Two pigs fed on skim milk from 14 to 

 16 days gained 26.4 and 66.8 per cent in weight. Two pigs fed on the same skim 

 milk, with 2 and 3 per cent of lactose added, gained 79.7 and 88 p6r cent in weight. 

 Two pigs fed on the same skim milk, with 2 and 3 per cent dextrose added, gained 

 73.6 and 64.4 ])er cent in weight. 



"Those fed with plain skim milk gained 114 and 218 gm. in weight for every 1,000 

 l)hysiologically available calories in the food. The lactose pigs gained 222 and 215 

 gm. per 1,000 calories in the food. The dextrose pigs both gained 213 gm. per 1,000 

 calories in the food. Except in the case of one ill-nourished skim-milk pig, the 

 growths of the sucklings stand in a constant ratio to the calories in the food. 



"The pigs fed on plain skim milk used 23 and 35 per cent of the proteid in the 

 food for tissue growth, the lactose pigs used 38 and 44 per cent, and the dextrose pigs 

 48 and 42 per cent. All the pigs of the second litter gained in fat when fed on plain 

 skim milk or on skim milk with sugars. 



" The percentage of calcium in the bodies of the pigs diminished with their growth. 

 There was considerable and normal deposition of calcium in the pig, and this was 

 proportional not to the calcium in the food, but to the growth of the animal. Not 

 only is the growth in grams of the pigs proportional to the calories in the food, but 

 the number of calories retained in the tissue substance during growth is i)roporti(inal 

 to the calories in the food. Eighteen to 19 per cent of the calories in the food were 

 found stored in the tissue growth of the pigs fed on the 3 varieties of skimmed milk. 



" There seems to be striking evidence that the suckling pig reared on skinnned 

 cow's milk conforms to the same laws of nutrition as the breast-fed infant." 



Measures for increasing pig raising, O. Knispel [Arh. Devt. Landv. (IfucIL, 

 1903, No. 77, pp. i.jf.v).— The author describes the methods followed in different 

 German States to encourage pig raising. He mentions the work undertaken by 

 breeding societies, offering of prizes, vaccination of pigs, and related topics.
