440 EXPERIMENT STATION RECORD. 



"A study of these epidemics teaches iis that — 



"(1) Whenever a case of communicable infectious disease is reported inqiiiry into 

 the source of the milk supply should be made. 



"(2) Milk traffic should be separated from houses where people live. The dairy 

 building should be at least 100 ft. from either the house, barn, or privy, and should 

 be on a higher level than any of these, and should have a pure water supply of its 

 own. At this dairy building all the dairy work should be done, including the cleans- 

 ing of pails and cans. 



"(3) It should be unlawful for anyone who has come in contact with a sick person 

 (when this sickness is not positively known to be noncontagious) to enter the dairy 

 building or barn, or to handle the milk. 



"(■i) All men connected with the milk traffic should be compelled to notify the 

 authorities on the outbreak of any disease in their respective abodes, and to abstain 

 from their work until permission to resume is given them by the authorities notified. 



"(5) Cities should accept milk only from dairies which are regularly inspected, 

 where all the cows have been tested with tuberculin and those giving the character- 

 istic reaction have been killed and the premises disinfected. 



"(6) The tuberculin test should be applied to all cattle, and those which react 

 should be killed, tlie owner being reimbursed from State funds. The premises on 

 which such tuberculous cattle have been kept should be thoroughly disinfected. 

 All cattle which are brought into the State should be quarantined until the tuber- 

 culin test has been applied. 



"(7) The use of one long trough for the purpose of feeding many cattle should be 

 avoided, since it is a ready means for the conveyance of pathogenic germs from one 

 animal to another." 



At what age should heifers be bred ? A. GouiN and H. George (Jour. Agr. Prat., 

 60 {1896), No. 46, pp. 713, 714). — General discussion of the subject. 



Bauauas for cow feed, A. H. Polk {Florida Farmer and Fruit Grower, 8 {1896), 

 No. 38, pp. 595, 596). — Cows ate freely the cured leaves, stalks, and roots of bananas 

 which had been injured by a frost. The author recommends feeding the roots of 

 bananas which have ripened fruit. The stumps were sliced for feeding. The cows 

 were fed banana roots during the winter and very little other food. In the author's 

 opinion their milk yield was increased and was of the best quality. 



The effect of peat-molasses feed and of ruta-bagas on the qualities of the 

 butter, Lassen {Milch Ztg., 25 {1896), No. 24, p. 5<S-^).— Cases are cited from practice 

 in which the butter produced when the molasses feed was fed moderately gradually 

 became oily and of inferior quality, and when fed with only a small ration of grain 

 was almost unsalable. The bad effects were persistent for some time after the 

 molasses feed was dropped, and in the latter case did not disappear until the cows 

 were turned to pasture. Instances of injury to the butter from feeding ruta-bagaa 

 are also given. 



Economic feeding of milch co'wrs, J. B. Lindsey {Massachusetts Hatch Sta. Bui. 

 39, pp. 23). — The author discusses the principles of nutrition, rations, and composi- 

 tion of milk. A table showing the composition, digestibility, and fertilizing value of 

 the most important cattle feeds is given. 



Determination of yield of butter fat by cows to aid in breeding good milch 

 cows, H. Weigmann {Landw. Wochenbl. Schles. Hol8t.,46 {1896), Nos. 32, pp. 459-461; 

 33, pp. 473-475). 



Milk record of a herd {Milch Ztg., 25 {1896), No. 44, pp. 704, 705).— k record for 

 1895-'96 for the Kleinhof-Tapian herd of 10-1 East Prussian Dutch Cows. 



Milk yield of Oldenberger cows {Oesterr. Molk. Ztg., 1896, Sept.; abs. in Milch 

 Ztg., 25 {1896), No. 43, p. 669).— Record for one year of 9 cows. 



Trial milkings of Algauer cows {Mitt, des milchw. Vers, in Algau, 7 {1896), No. 5; 

 abs. in Milch Ztg., 25 {1896), No. 34, p. 539).
