DAIRY FARMING— DAIRYING. 



[Convention of milk and butter producers at Washington, D. C, 1916] 

 (Amer. Food Jour., 11 (1916), No. 6, pp. 244-253). — An account of the conven- 

 tion of milk and butter producers and other dairy interests held at Washington, 

 D. C, May 5 and 6, 1916 (E. S. R., 3-5, p. 98). 



On the change in the composition of the milk of cows, O. Allemann 

 (Milchto. Zentbl., 44 (1915), No. S, pp. 122, i23).— Analyses are given of colos- 

 trum milk and of milk at short intervals after parturition, showing the rapid 

 changes that take place. 



Effect of water in the ration on the composition of milk, W. F. Turner, 

 R. H. Shaw, R. P. Norton, and P. A. Wright (17. S. Dept. Agr., Jour. Agr. 

 Research, 6 (1916), No. 4, pp. 167-178, fig. l).—ln these studies four different 

 methods of varying the water content of the ration were used : A full v. a lim- 

 ited allowance of drinking water ; turnips v. a dry-roughage ration ; wet v. dry 

 beet pulp ; and green v. dry crimson clover. 



Certain individual cows at times produced milk having an abnormal fat con- 

 tent. This effect was apparently independent of the ration, as it occurred not 

 only with the high water-content ration but with the dry as well. 



A study of the data obtained in the four series, however, shows that the 

 watery character of the ration has no effect upon the fat content of the milk. 

 There was even less variation in the other milk constituents than in the fat. 

 This indicates that rations of varying water content have no effect upon the 

 composition of milk. 



A bibliography of literature cited is given. 



The influence of sickness on the composition and characteristics of cow's 

 milk, R. Bergema (Untersuchungen iiber den Einfluss einiger dusseren und 

 inneren Krankheitcn auf die Z%isammensetzung und die Eigenschaften der 

 Kuhmilch. Inaug. Diss., Univ. Bern, 1915, pp. 78). — The specific gravity of 

 milk was in general not noticeably altered by sickness of the animal. The 

 chlorin content was in general high. The milk-sugar content often showed a 

 decline, while the fat content was as a rule higher than noi-mal. The diastase 

 content showed an increase of this enzym, and the catalase content was very 

 often high.
