Corn meal and oil cake "fed dry and mixed produced gaina in weight with it per 



rent less grain than did car corn and oil cake fed separately, both dry. The gain in 



the corn meal lot was 28.(1 per cent greater than in the ear corn lot, The hogs 



, ing ear corn would not eat more than one-sixth as much oil cake as corn (the 



rob figured out) when both were allowed ad libitum." 



In the opinion of the author the severity of the weather had an unfavorable effect 

 on the gains made. The subject is discussed and data summarized regarding the 

 influence of temperature on gains, indicating "that extreme heat of summer and 

 extreme cold of winter act alike to the extent that they both occasion large energy 

 expenditure on the part of the animal, in one case to keep warm, in the other to keep 

 cool; and in either case occasion a great reduction in the profit from feeding in the 

 dry lot when compared with results obtained in spring and fall. These results, 

 however, do not apply to the feeding of hogs on pasture." 



The poultry industry in Tasmania, R. J. Terry (Agr. <nnl Stock Dept. Tas- 

 mania, Bui. 7. pp. 15, Jigs. 4). — Various questions connected with profitable poultry 

 raising under local conditions are discussed and some experimental data on fattening 

 poultry are briefly reported. 



DAIRY FARMING— DAIRYING— AGROTECHNY. 



Profitable dairying, C. L. Peck (New Yuri: Orange Judd Co., 1906, pp. XII J - 174, 

 figs. 34).— This is offered as "a practical guide to successful dairy management," and 



consists of 23 chapters in which are discussed the physiology of milk secretion, dairy 

 breeds, feeding cows, milking, care of milk, butter making, and similar topics. 



Breed, individuality, and heredity in the production of milk, M. Fischer 

 ( Landw. Jahrb., 35 ( 1906), No. 3; pp. 333-379, pis. 3).—\ study was made of the yield 

 and composition of the milk with particular reference to the casein of 12 cows repre- 

 senting 6 different breeds, and also of 10 cows selected from a large herd with a view 

 to showing the influence of individual characteristics and heredity. 



The milk of the mountain breeds including the Brown Swiss and Simmental 

 showed a higher percentage of fat, casein, and solids-not-fat than that of the low- 

 land breeds including the Oldenburg, East Fresian, Angler, and Wilstermarsch. The 

 average annual yield of the latter group, however, was greater, making the annual 

 yield of fat and casein of the 2 groups practically the same. In producing milk for 

 cheese making the Brown Swiss breed is considered especially valuable as compared 

 with the other breeds mentioned. 



Within the same breed the author finds in casein production as in fat production 

 marked individual variations. The transmission of individual characteristics. is dis- 

 cussed at some length. 



A test of a fly repellent, C. H. Eckles (Missouri Sta. Bid. 68, pp. 35-39).— The 

 entire dairy herd was sprayed with a fly repellent each morning during alternate 

 periods of 2 weeks each. The test was continued during the entire summer of 1903 

 and for 6 weeks in the summer of 1904. The yields of milk and fat during the 

 periods when sprayed and when not sprayed are tabulated and show no important 

 effects either upon the yield of milk or fat due to the use of the fly repellent. When 

 applied every morning the material used was fairly effective in protecting the cows 

 from flies, but the claim made that the material will protect cows if applied at inter- 

 vals of several days is considered erroneous. 



Milking machines, P. G. AVickex (Jour. Dept. Agr. West. Aust., 13 (1906), No. 

 4, pp. 301-303, pis. 2). — This is a summary of a report on the use of milking machines 

 in Western Australia, the author concluding that the Lawrence-Kennedy-Gillies 

 machine is now beyond the experimental stage and is working in hundreds of places 

 daily giving practical results. 



The composition of milk, H. D. Richmond (Analyst, 31 (1906), No. 363, pp. 

 170-130). — The average composition of 14,828 samples of milk analyzed during 1905
