474 EXPERIMENT STATION RECORD. 



[Live stock in foreign countries], E. G. Babbitt, A. W. Thackara, and J. A. 

 Smith (Mo. Cons, and Trade Rpts. [U. S.], 1909, No. 3.',5, pp. 81, 82).— The 

 latest available statistics of live stock in Japan are for the year 1905, which 

 show M steady decrease in the number of animals since 1900, but there may have 

 been an increase in the past 2 years owing to a movement encouraged by the 

 government to improve the breeds of cattle and horses and to increase the 

 number to meet the growing demand. The imports of live stock from the 

 United States in 1907 were valued at $18,022. The Japanese use but little 

 milk and butter and there is no demand for cheese except among the foreign 

 residents and to supply hotels. 



In Prussia during the past 3 years there has been an increase in the number 

 of horses and cattle and a decrease in the number of sheep and hogs. In Italy 

 the value of live stock was $350,044,000 in 1881 and $772,000,000 in 1908. This 

 increase is accounted for in part by the improvement of the breeds and the 

 higher prices of meat products. 



Live stock statistics of Bavaria (Bcitr. Statis. K. Bayern, 1907, No. 72, pp. 

 135, maps 4). — The statistics of live stock in Bavaria, taken in December, 1907, 

 show a large increase in the number except for horses. The increase in cattle 

 is noticeably large, being a gain of 219.543 since 1904. 



DAIRY FARMING— DAIRYING— AGROTECHNY. 



Soy beans and soy cakes, D. A. Gilchrist (Mark Lane Express, 100 (1909), 

 No. .'fOo-'f, p. 667). — This is a report of a feeding experiment to test the com- 

 parative value of soy bean and decorticated cotton-seed cakes as feeds for milch 

 cows. The trial included 6 cows, and the basal ration consisted of hay, oat 

 straw, crushed oats, and roots. With soy bean cake as a supplementary feed 

 for 6 weeks the average daily yield of milk was 22.1 lbs. per cow. When 

 decorticated cake was substituted for the same period the average daily yield 

 was 21.6 lbs. per cow. 



Soy bean cake, J. Hansen (Deut. Landw. Presse, 36 (1909), No. Jfl, pp. ^39, 

 JiJfO; Jfo2, 453). — In this experiment with 3 cows and lasting" 6 weeks, soy 

 bean cake from which the oil had been extracted was contrasted with linseed 

 cake. The basal ration was composed of hay, bran, and sugar chips. The 

 average yield per cow per day during two periods of 14 days each when fed 

 the linseed cake was 1.3.14 kg. of milk, testing 3.45 per cent of fat. The cor- 

 responding yield during one period of 14 days with soy bean cake as the supple- 

 ment was 13.55 kg. of milk, testing 3.33 per cent of fat. 



Nuclear division in the milk glands of cattle, A. Zimmermann (Ztschr. 

 Fleisch u. Milehhyg., 19 (1909), No. 9, pp. 311-319, pi. i).— From his investiga- 

 tions the author thinks that mitotic division of the cells in the milk gland takes 

 place during all stages of milk secretion, although it can be demonstrated only 

 by taking great pains. Although 1,000 preparations were carefully made but 

 8 cases of mitotic division were found. A bibliography on the subject is 

 appended. 



On the factors which determine the increase in the function of the mam- 

 mary g'land, C. FoA (Arch. Fisiol., 5 (1908), No. 6, pp. 520-556, figs. 2; abs. in 

 Zentbl. Physiol., 22 (1908), No. 23, pp. 7^9, 750).— Subcutaneous and intra- 

 peritoneal injections of extracts obtained from a bovine fetus were made for 20 

 days in virgin rabbits. At the end of 15 days there was a noticeable enlargement 

 of the mammary gland. From the 2 rear glands a drop of milk could be 

 pressed out on the last day. No such effect was produced when the extract 

 was heated to 110° C.
