breeds, using lucerne hay, oat straw, potatoes, cocoannt meal, peanut meal, 

 v/heat bran, and rye meal as feeding stuffs. The quantities of the different 

 materials were varied in the several feeding periods in accordance with the 

 purposes of the study. From the results the author concluded that, provided 

 the proper nutritive ratio was maintained, neither gradual nor sudden changing 

 of the quantity of dry matter in the ration had any influence either upon the 

 digestion or health of the cow or upon the milk or butter fat production. 



Report of feeding tests for 1904-1907, Van Der Zande (Verslag. Ver. 

 Exploit. Proefzuivelhoerderij Hoorn, 1906, pp. 13-6.'f). — This article gives the 

 details of a study of the relative value of a ration containing fodder beets, 

 straw, hay, cotton-seed meal, and peanut meal as compared with the hay and 

 linseed meal ration in comnion use for milch cows. For 3 seasons 2 groups of 

 10 cows each, each group as nearly uniform as possible as to milk pi'oduction 

 and yield of fat and of dry matter, were used in these tests, one group being 

 fed with the former ration and the other with the latter ration. 



The data discussed by the author are those regarding the quantity of milk 

 and of fat and total dry matter in the milk, the quantity and quality of cheese 

 and butter, the changes in the live weight of the animals, and the financial 

 outcome of the two methods of feeding. In the avei'age for the 3 years the milk 

 production was 10.5 per cent larger on the beet ration, and the average fat con- 

 tent 0.2 per cent lower, while the dry-matter content of the milk was the same 

 on one ration as on the other. The total quantity of dry matter produced was 

 9.4 per cent more, that of fat 3.2 per cent more, of cheese 9.5 per cent more, of 

 cream butter 5.7 per cent more, and of whey butter 15 per cent more on the 

 beet ration than on the other. 



Report of fodder tests at Uithuizen, conducted during the winter 1906-7, 

 C. K. Van Daalen (Cultura, 19 (1907), No. 230, pp. 657-61^ ) .—The data of 

 the tests are given in detail and fully discussed. As these comprised only one 

 series with the rations studied, definite conclusions are not drawn, but the re- 

 sults indicate that beet tops constitute a fodder that, with hay, straw, and con- 

 centrates, may be fed to milch cows with profit, and that fodder beets may ad- 

 vantageously replace part of the concentrates. Fodder beets had a more 

 favorable influence on the quantity of milk and butter fat than the beet tops, 

 and the live weight of the animals increased on the ration containing the for- 

 mer. As compared with this, however, the cost of the ensiled beet tops was less, 

 Fodder beets showed the most favorable effect in respect to milk and butter- 

 fat production. As regards the butter fat, there was little difference between 

 the results from concentrates and those from ensiled beet tops.

Report of Alnarp agricultural and dairy institute. 1906 {Ber. Verks. 

 AJnarps Landtbr. Inst, och Mcjeri Inst., 1906. pp. JfS+XXXXVI). — The report 

 gives the usual account of the work of the institutes during the year. A feeding 

 experiment with legumes (ground peas) r. oil cakes for milch coWs, conducted 

 by the dairy department, is also reported. 



Twentieth annual report of the Bern dairy school at RUtti-Zollikofen 

 (JnJiresber. Molk. Schule Rittti-ZoUikofen. 20 (1906-7), pp. 61). — This includes, 

 in addition to an account of educational matters at the dairy school, a sum- 

 mary of articles on the work of the year at the dairy institute on centrifuging 

 the whey from fat cheese to recover the residual Initter fat, results of the con- 

 trol of the quality of milk and milk products, analysis of niargarin cheese, ob- 

 servations on the influence of fertilizer on the fitness of milk for cheese making, 

 and various statistics regarding the cheese and creamery industries.
