The transformation of food fat into milk fat. S. Gogitidse Ztschr. Biol., 45 



— In 3 experiments with sheep and 1 with a dbg 

 linseed oil in varying quantities was fed and determinations were made of the i<>ilin 

 number of the milk fat before, during, and after the oil-feeding period. The linseed 

 oil caused a rapid increase in the iodin numbers, which, after the oil was withdrawn 

 from the rations, slowly returned to the normal. As much as 33 per cent of the 

 constituents of the linseed oil was estimated as having passed directly into the 

 milk fat. 



ith which the iodin numbers of the milk fat decreased indicated 

 that a portion of the linseed oil had been transformed into body fat during the feed- 

 ing period and later retransformed into milk fat. It is therefore concluded that food 

 fat passes into the milk in two ways. 1 | directly and | 2 • indirectly through the 

 body fat. the greater part of the transformation taking place directly. A marked 

 decrease in the yield of milk was attributed to the influence of the linseed oil. A 

 bibliography i- appended. 



Note on Dr. S. Gogitidse's article entitled. "The transformation of food 

 fat into milk fat," W. Caspari {Ztschr. Biol., 46 {1904), No. 2, pp. 277-279).— 

 Attention is called to investigations by the author, published in 1899 | E. S. K.. 11. 

 p. 973 . the results of which " -- ttially the same as those recently obtained by 



ritidse in the article noted above. Caspari estimated that in his experiments 

 :*>2.4V» per cent of the milk fat came from the iodin fat fed; Gogitidse, 33 per cent 

 from Unseed oil. 



Comparative investigations on the quality and quantity of the milk of the 

 two principal breeds in Carinthia, H. Svoboda {Osterr. Molk. Ztg., 11 {19 

 Nos. 14. pp. 191-193; 15, pp. 205-207; separaU from Carinthia II. 1904, No. 2-3, 

 pp. 31 I. — From data collected during a period of 3 years the following averages were 

 obtained for the 2 breeds of cows: MoUtaler, annual yield. 2,056 to 2,250 kg.; specific 

 gravity of the milk. 1.0328; total solids, 13.22 per rent: fat. 3.86 per cent; soUds-not- 

 fat, 9.39 per cent: Blondvieh, annual yield. 2,089 to 2,409 kg.; specific gravity of the 

 milk. 1.0328; total solids. 12.76 per cent: fat, 3.67 per cent: and solids-not-fat, 9.09 

 per cent. 



Report of the experiment station and school for dairying at Kleinhof- 

 Tapiau. 1903-4, Hittcher {Ber. Tat. I" 5 . Lehranst. Molhw. Kleinhof-Tapiau, 

 1903-4. i rp. 11). — This is a summary of the work during the year, with tabulated 

 data showing the average yield and composition of the milk of over 103 cows and 

 also variations from morning to evening and from day to day in the yield and com- 

 position of the milk. 



The average composition of the milk of lis cows for 10 years | 1887-1897) was as 

 follows: Specific gravity. 1.0306: fat content; 3.18 per cent: total solids. 11.73 per 

 cent: solids-not-fat. 8.55 per cent. The lowest fat content was 2.36 per cent. During 

 1903-4 the fat content averaged 3.50 per cent, the extreme daily variations being 

 2.61 to 3.50 per cent. Total solids varied from 11.095 to 12.263. ami averaged 11.613 

 per cent.

 pp. 22 . — This contains an outline of experimental work during the year with state- 

 ments concerning results obtained. The work included tests of dairy apparatus, a 

 study of some molds in dairy products, chemical and bacteriological investigations 

 of the butter in the Province of Posen, studies of method- of examination of milk and 

 milk products for the detection of adulteration, analyses of dog's milk. etc.
