DAIRY FARMING— DAIRYING. 



Feeding dairy cows, J. W. AVilson and H. G. Skinner {South Bal-ota Sta. Bid. 

 81, pp. -7-40) . — Several feeding stuffs were compared in experiments with grade and 

 pure-bred cows. In the first test 15 cows were divided into 3 lots as nearly uniform 

 as possible, and fed the same kind of grain ration for a period of 27 days. The rough- 

 age for lot 1 was corn silage, for lot 2 Bromus inermis hay, and for lot 3 alfalfa hay. 

 The data are tabulated and notes are given on the individuality of the cows. During 

 the test lot 1 consumed 1,575 lbs. of silage and 335 lbs. of grain, awd jiroduced 25.28 

 lbs. of butter fat at an average cost of 14.45 cts. per pound; lot 2 consumed 576 lbs. 

 of brome grass hay and 340 lbs. of grain, and produced 24.58 llis. of butter fat at 14.72 

 cts. per pound; and lot 3 consumed 389 lbs. of alfalfa hay and 336 lbs. of grain, and 

 produced 19.53 lbs. of butter fat at a cost of 16.35 cts. per pound. 



In 2 subsecjuent periods of 21 days each, spelt, barley, and corn were compared 

 with the same lots, one cow in each, however, being replaced by a fresh one. The 

 roughage was uniform in character during the test. The grain required for the pro- 

 duction of 1 lb. of butter fat was, on an average, as follows: Spelt 17.5, corn 15.5, 

 and barley 15.5 lbs. The cows gained in weight when fed spelt or barley and lost 

 when fed corn. Fresh cows produced Ijutter fat with less grain than cows in advanced 

 lactation. The beef-bred cows required one-third more grain to produce a pound of 

 butter fat than the dairy-bred cows. 



Economies in dairy farming, E. INIathews {Londo)i: Country Life, 1903, pp. 

 XI \ 68, pis. 39). — This book is based in part upon tests of over 1,500 cows made 

 during a period of about 10 years, and contains many suggestions relating to the 

 economical production of milk and butter. Some of the subjects discussed are the 

 composition of milk, characteristics of dairy cattle, feeding dairy stock, economical 

 disi)osal of milk, and hints on butter making. Under characteristics of dairy cattle, 

 the effect of breeding and selection is illustrated by the early history of the Shorthorn 

 and Jersey breeds, and considerable space is devoted to a discussion of the escutcheon. 

 ]Methods of keeping farm accounts are also described and illustrated.
