774 EXPEEIMENT STATION RECORD, 



[Dairying], Miss E. A. Maidment (Rhodesia Agr. Jour., 8 (1911), No. 3, pp. 

 423-434). — Some notes on the general condition of the dairy industry in Rho- 

 desia. 



The cattle at the Kon-Kolodiesk Agricultural Scliool, A. V. Abriutin 

 (Selsk. Khoz. i Licsov., 234 (1910), Oct., pp. 234-24G, figs. 3; ahs. in Intcrnat. 

 Inst. Agr. [Rome], Bui. Bur. Agr. Intel, and Plant Diseases, 1910, No. 2, pp. 

 310, 311). — An account of the dairy herd of the agricultural school of Kon- 

 Kolodiesli. 



The breeds repi'esented are Simmental and crosses of this with native Rus- 

 sian breeds. The milk yield has been increased by careful selection for a 

 number of years, while the average live weight has decreased. The average 

 fat content for 15 years has been 4.5 per cent. 



[Feeding experiments with dairy cows], E. Barnett (South Carolina Sta. 

 Rpt. 1910, pp. 69-71). — A brief report of the work in animal husbandry at the 

 station. 



In the study of the physiological effects of feeding cotton-seed meal in large 

 amounts to dairy cows, it was found that 4 lbs. per head per day could be 

 safely fed to mature cattle in connection with other feeds, but that when fed 

 in amounts from 6 to 8 lbs. per head and day for periods of from 1 to 3 years 

 the milk production was lessened, and it was thought to be the cause of mam- 

 mitis and abortion. 



The average cost of the feed for 17 cows was $57.23 per head per annum. 

 The average yield of milk was 5,741 lbs., containing an average of 4.5 per cent 

 fat. 



[Milking machine] (NeiD Zeal. Dairyman, 15 (1911), No. 5, p. 15). — ^A 

 description of a new type of milking machine, said to be simple in construction 

 and easily cleaned. 



The cow's udder and the process of milk production, M. H. Reynolds 

 (Hoard's Dairyman, 42 (1911), No. 10, pp. 345-350, figs. 10). — ^A popular ac- 

 count of the physiology of milk secretion and the structure of the tissues 

 concerned. 



[Milk secretion], K, Basch (Deut. Med. Wchnschr., 36 (1910), No. 21, pp. 

 987-990; abs. in Hyg. Rundschau, 21 (1911), No. 3, p. i75).— From studies of 

 the innervation of the mammary gland and experiments in transplanting the 

 gland from the ventral to the dorsal side of dogs, the author concludes that milk 

 secretion is not stimulated by means of the nervous system, but by a stimulat- 

 ing constituent of the blood. Injections of placental extracts also induced milk 

 secretion. It is stated that this view is supported by the case of the Blazek 

 sisters, who were connected twins but had separate nervous systems, and both 

 of whom secreted milk after one of them had given birth to a boy. 



Investigations on the milk production of rutting cows, B. Weber (Ililchiv. 

 ZentW., 7 (1911), No. 1, jjp. 1-19). — In only a few instances was the yield of 

 milk or the percentage of fat reduced during the rutting period from that of a 

 normal condition. As a rule there was no change in the taste, appearance, or 

 character of the milk, except that it did not coagulate readily upon boiling. 

 Whenever the cow was unduly excited there was a high percentage of acidity, 

 and sometimes the milk was exceptionally yellow in color. 



A bibliography is appended. 



Milk from slop-fed cows, A. Rolet (Lait. et Indus. Ferme [Paris], 20 

 (1910), No. 12, pp. 89, 90). — This is an unfavorable view concerning the use of 

 distillery slop for feeding dairy cows, on the ground that on feeding large quan- 

 tities the flavor, odor, and acidity of the milk are affected. The opinion is 

 expressed that milk coming from cows fed distillery slop should never be 

 labeled "sanitary milk."
