 pp. 30, 31). — Analyses are reported of wheat bran, shorts, middlings, mixed 

 feeds, and stock foods.

 Analyses are reported of middlings, corn and oats, ground oil meal, flax bran, 

 molasses feed, and proprietary mixed feeds.

 {Staz. Spcr. Agr. Ital.. J,S {1910), No. 3, pp. 273-282; ahs. in Zentbl. Agr. Chem., 

 40 {J 911), No. 5, pp. 358, 359). — ^Analyses are reported on the nutritive value of 

 corn cobs from different varieties of corn, and their value for feeding stock is 

 discussed. 



The conservation of products from sugar factories and distilleries, R. 

 Sarcin {Circ. Hehd. Syndicat Fahr. Sucre France, 1909, No. 1079; ahs. in 

 Ztschr. Ver. Deut. Zuckerindus., 1910, No. 649, II, p. 105; Zenthl. Agr. Chem., 

 40 {1911), No. 3, p. 212). — A method for treating beet chips with a lactic ferment 

 known as " lacto-pulp " is described. Successful experiments in feeding the 

 fermented product to cattle and sheep are reported. 



Notices of judgment {U. S. Dept. Agr., Notices of Judgment 902, 913, p. 1 

 each; 923, pp. 2). — These relate to the adulteration of alfalfa hay and stock 

 feeds. 



Observations on rumination, E. Belz (Physiologische und Klinisehe BeO' 

 hachtungen iiber 4ie Rumination. Inaug. Diss., Univ. Giessen, 1910, pp. 92; rev. 

 in Zenthl. Biochem.. u. Biophys., 10 {1910), No. 9-10, pp. 453, 45 i)- — The average 

 number of movements of the .law to masticate 1 bolus was as follows: Grown 

 cattle, 49 ; calves, 60 ; sheep. 78 ; and goats, 60. The number of seconds the 

 bolus remained in the mouth was for mature cattle 53, calves 55, sheep 61, and 

 goats 70. Rumination began from f to li hours after eating. In all rumi- 

 nants there were from 4 to 6 masticating periods, lasting from 25 to 35 minutes. 



The significance of the mechanical part of the energy of digestion of 

 cattle, K. Dahm {Biochem. Ztschr., 28 {1910), No. 5-6, pp. 456-503; ahs. in 

 Zenthl. Physiol., 25 {1911), No. 2, p. 86). — To compare a ration rich in fiber 

 with an easily digested ration a young bull was given a daily ration of 5 kg. 

 of Lay and 1 kg. of barley for 10 days. In the second period of the same 

 length the ration consisted of 1.5 kg. of hay and 2.5 kg. of barley. This con- 

 tained 1,086 gm. less of raw fiber than the former ration, and required 549 

 calories less energy. The energy required for chewing and for ruminating 1 kg. 

 of hay was determined to be 52.3 and 41.9 calories, respectively. Eight per 

 cent more energy was required when standing than when lying down. 



On substituting a foreign fat for milk fat in feeding skim, milk to calves, 

 C. Besana -{Stas. Sper. Agr. Ital., 43 {1910), No. 1, pp. 86-90; ahs. in Zenthl. 

 Agr. Chem., 40 {1911), No. 7, pp. 501, 502). — Margarin and skim milk were 

 gradually substituted for whole milk in feeding 4 calves, which made an aver- 

 age daily gain of 0.717, 1.23, 0.897, and 0.923 kg., respectively. 



Breeding from ewes at an early age, J. Mackintosh {Jour. Southeast. Agr. 

 Col. Wye, 1910, No. 19, pp. 25-29). — A later report of work previously noted 

 (E. S. R. 25, p. 273). During the second year the difference in weight between 

 the 2 lots of ewes was diminished because the earlier bred ewes lost much 

 less in live weight than did the lot of ewes mated at 20 months of age.
