DAIRY FARMING DAIRYING AGROTECHNY. 573 



Average yield, cost of »iaintcnance, and net profit per cow of 5 dairy herds. 



In estimating the total iucome the value of the calf was estimated at $2 and 

 the manure at $10 per year. lu computing the total cost a charge of $45 ^iev 

 year was made for the maintenance of each cow. It is stated that the first 

 four herds are examples of the most advanced methods in dairy farming. 



Dairying in China, J. H. Arnold {Dally Cons, and Trade Rpts. [U. S.], 1909, 

 No. 3537, p. 6). — The consul at Amoy, China, reports that the Amoy hinterland 

 is a good cattle grazing country but that dairying is almost unknown. Cows 

 have been bred for work rather than for milk. Most of the milk used in China 

 is produced by the water buffalo and the black goat. There is a growing 

 demand for condensed milk, which may eventually lead the people to appreciate 

 the value of milk and take more interest in daii'ying.

Better dairy methods, .J. H. Frandson {Idaho Sta. Bui. 67, pp. 3--'i8, figs. 

 18). — Investigations by the station having shown that in many sections of 

 Idaho cows are kept at a loss, this bulletin was prepared to supply the dairy- 

 men with such information as is needed to make dairying more profitable 

 under conditions existing in the State. The principal topics treated are con- 

 struction of the dairy barn and milk house, choosing dairy animals, feeding, 

 keeping milk records, testing milk, and the care of milk and cream. 



Report of Oesterg-btland Company Cow-testing" Associations, 1907—8, 

 K. A. Westman {Ostergotlands Lans Hushdll. Sdllsk. Hand!., 1909, No. 2, pp. 

 95). — Thirty -nine different associations were in operation within the county 

 during the year, and 8 new ones were formed ; these 47 associations included 608 

 different herds and 19,968 cows, making 18.5 per cent of the total number of 

 cows in the county. The cost of the associations ranged from 515 to 1,113 krone 

 a year each, or from 1.24 to 5.98 krone per cow. The maximum yields per cow 

 for any one association were 4,315.3 kg. milk and 164.24 kg. butter. Compari- 

 sons of the results obtained during successive years show that there has been a 

 gradual increase in the yield and in the feed consumption of the herds, as well 

 as in the returns obtained per 100 feed units consumed.
