of 9 COWS each, were fed two weeks a ration of alfalfa hay, dried beet pulp, and 

 wheat bran, lot 1 being then continued on the same feed for two weeks longer, 

 while lot 2 was fed for two weeks on beet pulp and alfalfa hay. During these 

 last two weeks lot 1 fell off 156 lbs. in milk yield, and lot 2 316 lbs. The loss 

 of lot 1 is thought to be the normal loss due to advancement of the period of 

 lactation and other natural causes. It is estimated that the actual saving by 

 feeding beet pulp instead of beet pulp and bran was $3.72 in two weeks. 



Body form and milk yield, E. Augustin (Flugschr. Detit. Oesell. ZiicMungsk.,

Holstein-Friesian makes world's dairy record (Breeder's Oaz., 61 (1915), 

 No. 13, p. 671). — It is announced that the Holstein-Friesian heifer Finderne 

 Holingeu Fayne has broken all world records for fat production by producing

Cost of milk, W. A. Linklater (Washington Sta., West. Wash. 8ta. Mo. 

 Bui., 2 (1915), No. 10, p. 13). — From records kept during a 12-month period of 

 a herd of from 12 to 10 head of cows, the computed cost of milk was $9.89 per 

 month per cow, or 3.9 cts. per quart. The cost of feed and pasture for the entire 

 herd for the year was estimated to be $720.16, and of labor $770. 



From experiments conducted in cooperation with a condensed milk concern, 

 it was concluded that contamination of milk after it is drawn is the cause of 

 inferior quality for condensing purposes rather than the feed eaten by the cow. 



The useful and harmful bacteria of milk, R. Pfister (Milchw. ZentM., 43 

 (1914), No. 18, pp. 4^^-469). — In this article the author discusses the value

 bacteria often found in milk. 



The devitalization of tubercle bacilli in milk by means of electricity, F. C. 

 Lewis (Tuberculosis Year Book, 1915; ahs. in Jour. Bd. Agr. [London]^ 21 

 (1914), No. 9, p. 844)- — Experiments conducted at the University of Liverpool 

 demonstrate that electricity can be successfully applied as a sterilizing agent in 

 milk. It is claimed that the total bacterial count is greatly reduced, all Bacil- 

 lus coli and its allies are destroyed, tubercle bacilli are destroyed, no chemical 

 changes in the milk can be detected, and the taste of the milk is unaltered.
