are worth fully one-half as much again as wheat bran. Brewers' dried grains and 

 malt sprouts do not vary greatly in feeding value; the former will generally be given 

 the preference. Brewers' grains and malt sprouts are rather superior in feeding 

 value to wheat bran, probably 10 per cent." 



Records of a dairy herd for five years, C. L. Beach (Connecticut Starrs Sta. 

 Bui. 29, pp. 32, figs. 18). — Individual records are given of 17 to 25 cows each year for 

 5 years. In all, records were obtained of 50 different cows, the total number of lacta- 

 tion periods being 103. The average annual production of milk for the 5 years was 

 5,498 lbs., and the average production of butter 326 lbs. The kind and amount of 

 food was much the same during the entire period. The increase in the net profits 

 from a loss of $1.23 in 1899 to a profit of $21.69 per cow in 1903 is attributed to the 

 selection of animals better suited to dairy purposes. 



The cows were classified as regards type into the dairy group, cows lacking digestive 

 capacity, and the fleshy group, the average profits of the 3 types being, respectively, 

 $28.09, $5.81, and $6.09. As regards the profits from butter fat, the Jerseys made 

 the best showing; but as regards the profits from milk, a much better record was 

 made by the Holstein breed. On an average the maximum yield of milk was obtained 

 during the third week of lactation. The fat content of the milk increased about 0.1 

 per cent each month during the first 10 months of lactation.

Dairy observations, ('. L. Beach (Connecticut StorrsSta. Bid. 28, pp. JO, Jigs. 7). — 

 This consists of reprints of 3 articles from the last annual report, namely, Dehorn-

 Cost of Raising Calves ( E. S. R., 15, p. 893). 



Standard milk, F. W. Morse (New Hampshire Sta. Bui. 103, pp. 79-82). — This is 

 a brief discussion of the composition of milk with special reference to the require- 

 ments of the New Hampshire law, which is quoted. As a means of meeting the 

 requirements of the law the careful selection and testing of cows is urged. To aid 

 farmers in this respect the station offers to make determinations of fat for 10 cts. per 

 sample, and total solids for 25 cts. per sample. Brief directions are given lor 

 sampling.
