DAIRY FARMING— DAIRYING. 



Manuring for milk, J. F. Blackshaw (Midland Agr. and Dairy Col. Bvl. 1, 

 1909-10, pp. 10, dgm. 1, charts 2). — A preliminary report on experiments in 

 improving pastures for dairy cows. 



Following an application of lime, 400 lbs. of superphosphate and 1.50 lbs. 

 of sulphate of potash per acre were applied to a pasture with a rather poor 

 clay soil. The milk produced by the cows pastured on the fertilized lot was 

 at the rate of 84 gal. per acre, valued at £2 2s., in excess of that on the 

 irafertilized lot. The cost of the fertilizer was fl 13s. 



Breeding for production in dairy cattle in the light of recent advances in 

 the study of inheritance, R. Pearl (Agr. of Maine, 1909, pp. 190-200). — ^A 

 paper read before the Maine Dairymen's Association in 1909. 



It is shown from exijeriments in breeding plants and poultry that the old 

 method of selecting breeding stock by performance alone does not lead to the 

 results which were formerly supix)sed to exist. The lesson for the dairyman 

 from these experiments is that in order to improve his stock it must be done 

 not by selecting cows in the " advanced registry " but by selecting bulls which 

 show a large percentage of daughters in the " advanced registry." In this new 

 method of selecting breeding .stock it is not the ability to produce milk, but the 

 power to transmit the ability, which is the desideratum. 



What gives us the satisfactory dairy cow — " Her breeding," W. W. Marsh 

 {Ann. Rpt. Wis. Bd. Agr., 1910, pp. J,09-Ji20) . — A lecture before the Wisconsin 

 Board of Agriculture in 3910. The difference between show type and producing 

 type is discussed, and it is pointed out that the improvement of the dairy type 

 can only be brought about by breeding animals with an ancestry which shows 

 a great productive capacity. 



Investigations on the influence of pasturing and stabling upon dairy 

 cattle, with special consideration of the changes in the epidermis, P. Riegeb 

 {Untersuchungcn iibcr den Einfluss von Weidegang und StallhaUung auf das 

 Milchvieh, mit desonderer BcrUclcsichtigung der Verdnderungen der dusseren 

 Decke. Inaug. Diss., Univ. Bern, 1910, pp. 36, figs. 2; Deiit. Lamlw. TierzucM, 

 U (1910), Nos. 26, pp. 305-309; 21, pp. 317-320; 28, pp. 329-332) .—The author 

 records some observations on the differences in the conformation and in the 

 character of the hair between dairy animals at pasture and those kept in the 

 stable. 



Milk, its investigation and usage, F. Utz (Die Milch, ihre Uniersucliung 

 und Vertvertung. Vienna and Leipsic, 1911, pp. 261/, figs. 72; rev. in Mollc. Zfg. 

 [Hildesheim], 25 (1911), No. 15, p. 258).— A general treatise on milk and its 

 properties, based largely on the results of recent investigations. 



Market milk and its inspection, W. Bremme (Ztschr. Fleisch u. Milchhyg., 

 21 (1910), Nos. 2, pp. 33-il; S, pp. 68-76; 21 (1911), Nos. 4, PP- 110-118; 5, pp. 

 152-160).— This series of articles discusses the chemistry of the composition of 

 milk, the changes caused by bacteria in its transit to the consumer, and methods 

 of official control in order to insure a sanitary product. A bibliography is 

 appended. 



A study of some of the spore-bearing anaerobic bacteria in market milk, 

 H. R. Brown (Ann. Rpt. Bd. Health Mass., J/l (1909), pp. 632-667).— A bac-

 obtained their milk supply from different contractors, who, in turn, received
