ANIMAL PRODUCTION. 507 



During 1912 these plats were pastured with sheep. The average weight of 

 sheep carried ver acre on the several plats was 440, 460, 489, and 441 lbs., re- 

 spectively, and the average increase per sheep in 16 weeks was 43.9, 45.2, 51.5, 

 and 42.6 lbs. 



During 1013 these plats were jia.stured to cattle in the early part of the sea- 

 sou and sheep in the fall. The average increase per acre for the 3-months' 

 cattle feeding was 233, 271, 254, and 295 lbs., respectively. The average weight 

 of .sheep carried per acre was 239, 189, 184, and 188 lbs., and the average in- 

 crease i>er sheep during 10 weeks pasturing was 11.5, 16.8, 15. and 12.6 lbs., 

 respectively. The total value of produce per acre for the one year of haying 

 and two years of pasturing was £15 69. lid., f 16 5s. Id., £16 7d., and £14 16s. 7d. 



The results obtained from these plats for the three years show, as a whole, 

 that a heavy seeding with rye grass, such as was given plat 1, is not superior 

 to a lighter seeding, such as was given plat 2, or to a mixture without rye 

 grass, such as that of plat 3. 



Chemical composition of moor hay causing excessive licking in cattle, 

 H. VON Feilitzen {Svcnska AlosskuUurfdr. Tidskr., 28 {1914), ^^o. 2, pp. 155- 

 161; abs. in Inteniat. Inst. Agr. [Rome'\, Mo. Bui. Agr. Intel, and Plant Dis- 

 eases, 5 (1914), ^'o. 8, pp. 1002, 1003). — Samples of moor hay which cau.sed 

 an excessive desire to lick in cattle were analyzed and found to contain a larger 

 quantity of sodium and chlorin than other hays, thus no doubt furnishing salt 

 de.sired by the cattle. 



Modern silage methods, W. L. Wright {Salem, Ohio: The Silver Manufac- 

 iuring Co., 1914, 10. ed. rev., pp. 264. figs. 77). — General information on methods 

 of ensiling crops and their feeding to farm animals. 



The ensiling of beet tops with lactic acid bacteria, D. Meyek (Landw. 

 Wchn^schr. Sachseti, 16 {1914), No. 26, pp. 231, 232).— In experiments in which 

 beet tops were ensiled for 160 days, with and without the use of a lactic acid 

 culture, it was found that the loss of nutrients was in all cases greater in that 

 material ensiled without the use of the culture than that to which it was added. 

 The addition of the culture improved the aroma and palatability of the silage. 



The ensiling of potatoes with a lactic acid culture, D. Meyer {Landio. 

 Wchmchr. Sachscn, 16 {1914), A'O. 12, pp. 106, 107).— It is stated that potatoes 

 may be ensiled with less fermentation loss by the use of lactic acid culture. It 

 is estimated that the loss in diy matter is 4.9 per cent, in protein none, in nitro- 

 gen-free matter 5.6 per cent, and in fiber 21.8 per cent. The ferment used for 

 this purpose is Baeillus delhriieki in the case of steamed potatoes, and for raw 

 potatoes and roots B. cueumens fcrmentati. The ensiled product is high in 

 sugar content and is valuable for all kinds of stock. 



Ensiling potatoes {Ztscln: Landw. Kammer Sehlesien, 18 {1914), ^os. 38, 

 pp. 1485, I486; 39, pp. 1505. 1506). — Directions are given for the ensiling of 

 both raw and cooked potatoes. A lactic acid culture is added to hasten the fer- 

 mentation process. It is stated that horses, cattle, and sheep can use 40 kg. of 

 this material per 1.000 kg. live weight per day. while fattening hogs use a 

 smaller quantity. 



The utilization of marc for the feeding of cattle, L. Degrully {Prog. Agr. 

 et Tit. (Ed. VEst-Cenfrc), 35 (1914), Xo. 37. pp. 300-303).— \ summary of 

 data based largely on the work of Fabre previously noted (E. S. R.. 21, p. 

 667). It is suggested that from 10 to 12 kg. per day may be fed to horses and 

 mules together with bran and a small quantity of water, 20 to 25 kg. to cattle, 

 5 to 6 kg. to sheep, and 5 to 10 kg. to swine. 



Molasses and molasses feeds, J. E. Halligan (Baton Rouge, La.: Bd. Agr. 

 and Immifir. [1914]- PP- 2-12, fig. 1). — An account of the composition and feed- 

 ing value of cane and sugar-beet molasses, and of various molasses-mixed feeds.
