A suniiiiary of the feed units consumed and the milk f:it i»ivxluced wilh the 

 various crops is shown in the following table: 



Feed consumption and milk fat production on first, second, and third crop 



alfalfa hays. 



While these experiments indicate that second crop alfalfa is at least equal 

 in economy to the other crops, it is noted that it is less relished and that other 

 practical difficulties may tend to reduce its actual value. 



Manuring for milk, F. Wakerley {Midland Agr. and Dairy Col. Bui. 1, 

 1012-13, pp. 8, pi. 1). — A comparison of the feeding values of 2 pastures of 4 

 acres each, and treated with 10 cwt. ground lime per acre, one being also 

 fertilized with 4 cwt. superphosphate and 11 cwt. sulphate of potash per acre. 

 The total yield of milk during the 3 seasons, 1910-1912, was 8,740 lbs. on the un- 

 manured and 13,GG1 lbs. on the manured pasture. 



Winter feeding of dairy cows, J. Mackintosh {Jour. Southeast. Agr. Col. 

 Wye, 1912, No. 21, pp. 51-82).— In this article the author attempts to outline 

 a rational system of dairy cattle feeding, in which he discusses the Kellner. 

 Armsby, Hansson, and Haecker standards of feeding and suggests a number of 

 successful dairy rations involving home-grown feeds. 



The orig-inal St. Lambert Jerseys. — An account of their breeding, C. Clark 

 {KimhalVs Dairy Farmer, 11 {1913), No. 18, pp. 542-545, figs. 10). — The author 

 reviews the foundation, development, and capabilities of the St. Lambert strain 

 of Jersey cattle, and compares this American-bred type with the finer boned 

 Jersey Island-bred type. 



Comparative experiment between Red Danish milch cattle, Jersey cattle, 

 and Dane-Jersey cattle, J. J. Dunne {Hoard's Dairyman, 46 {1913), No. 9, pp. 

 234, 235). — Comparing these 3 groups, consisting of 15 cows each of approxi- 

 mately the same age, during a period of 2 seasons as regards their average 

 yields and cost of production, the results as summarized in the following table 

 were obtained : 



Average yearly yield and cost of production per coio. 



In churning and buttermaking experiments the Jersey butter was firmer 

 and harder than the Red Danish, due to a lower olein content, but the feed- 

 ing of rape oil reduced this hard and brittle consistency.
