DAIRY FARMING— DAIRYING. 



Dairy farming', J. Michels (Milwaukee, Wis., 1911, 3. ed. rev., pp. 296, pi. 



I, figs. 81). — A pi-actical work on dairying, intended to be nsed as a text and 

 reference book in American dairy scliools, and wliich contains results of the 

 autlior's experience in dairy farming and as a teacher of dairy husbandry in 

 agricultural colleges. 



Soiling" and summer silage, H. O. Daniels (Amcr. Cult., 73 (1911), No. 49, 

 pp. 2, 3, fig. 1). — This is a comparison of these 2 systems of furnishing succu- 

 lent feed for dairy cows throughout the year, based on the experience of the 

 author. 



He found that growing clover and either oats, rye, or wheat for ensiling in 

 June was a more economical and satisfactory method, and required less laboi", 

 than summer soiling for keeping up the milk supply when the summer pastures 

 began to dry up in the summer time. In September, when the clover and rye 

 or wheat silage has been used up the silo was filled with corn silage, which 

 lasts until the summer silage is again ready for harvest. Details are given 

 for raising the crops. 



On the feeding value of fresh grass and hay made from the same, A. 

 MoBGEN, C. Beger and F. Westhausser (Landw. Yers. Stat., 75 (1911), No. 

 5-6, pp. 321-3't8). — ^Analyses of fresh grass and hay indicated that the loss 

 of organic matter through drying was slight. There was a loss of organic 

 phosphorous when dried in the open air, but not when dried in an enclosed box. 

 In tests with 3 sheep and 1 goat there was little difference in the milk flow or 

 live weight, although the hay was not quite so readily digested as the grass. 

 The greatest loss of nutrient material was in fat and pure protein. The 

 decreased digestibility was due to the changed physiological condition of the 

 hay. 



The external characteristics of dairy cows of different breeds (Cnlfura, 

 23 (1911), Nos. 270, pp. 74-93; 271, pp. 123-138).— A study of conformation as 

 a guide to the milking capacity of cows. 



Red Polls as milkers, T. A. J. Smith (Jour. Dept. Agr. Victoria, 9 (1911), 

 No. 11, pp. 778-781, fig. 1). — This reports the milk yields of 13 Red Polled cattle 

 kept at the tobacco farm of the department at Whitfield. 



Concerning the nutritive value of the milk of buffaloes and cows, G. 

 Magini (Atti. R. Accad. Lincei. Rend. CI. Sci. Fis. Mat. e Nat., 5. ser., 20 (1911), 



II, No. 8, pp. J,39-US, pi. 1; Clin. Vet. [Milan], Rass. Pol. Samt. e Ig., 34 (1911), 

 No. 23, pp. 933-1000). — Comparative analyses were made under corresponding 

 conditions of the milk of cows and Indian buffaloes obtained in and about Rome. 



The buffalo milk was found to contain considerably less water, one-third 

 again as much fat, and more albuminoids and milk sugar. The author concludes 

 that it is likely to become of increasing economic value in the Roman campagna. 



The dirt content of evening' and morning milk, F. Reiss (Mollc. Ztg. 

 [Hildeshcim], 24 (1910), No. 88, pp. 1655, 1656).— A number of tests showed 

 that the morning milk as a rule had a higher dirt content than evening milk. 



A preparation for increasing the secretion of milk, K. Basch (German 

 Patent 238,995, Aug. 21, 1909; ahs. in Chem. Ztg., 35 (1911), No. 127, Repert., 

 p. 527). — ^A note on a patented process for extracting from animal placentas a 

 substance which induces milk secretion. It is claimed that it can be used for 

 both animals and humans. 



The problem of city milk supplies, P. G. Heinemann (Pop. Sci. 3Jo., 80 

 (1912), No. 1, pp. 66-75, figs. 9). — A popular article on the importance of having 

 a pure milk supply. The fact is emphasized that consumers must be taught to 

 realize that at present prices milk is a cheap food as compared with meat.
