DAIRY FARMING DAIRYING AGROTECHNY. 373 



" The basis of this volume Is to be sought in the bulletins and reports of the 

 agricultural experiment stations, Federal and State departments of agriculture, 

 live-stock periodicals, other publications of this and foreign countries, and in 

 our own personal experience. The book, therefore, embodies those experiment- 

 ally established facts and principles of animal husbandry which at present are 

 our most reliable guides to profitable practice. 



"American stock raisers are in a position to produce economically the finest 

 of animal products of all sorts. The recent meat inspection law has enabled 

 the Bureau of Animal Industry to devise and put in operation the most efficient 

 system of meat inspection known to the world. This book is designed to en- 

 coui'age the stockman to do his part in increasing the national resources."

A test of soiling crops for dairy cows, T. L. Maiks and F. S. Putney 

 (Pennsi/lvaniu Sta. Rpt. 1907, pp. 73-85). — Further feeding tests of soiling crops 

 (E. S. R., 19, p. 877) were made, leguminous plants being used as far as pos- 

 sible. The crops tested during the year were alfalfa, clover and timothy, field 

 corn, cowpeas, rye, field peas and oats, Kafir corn and cowpeas. The saccharin 

 soi'ghums fed in former years were abandoned in favor of Kafir corn, which 

 seemed to be more palatable and furnished a better support for the cowpeas with 

 which it was planted. Tables are given showing the yields of green forage, 

 air-dry matter and protein, the length of time required for maturity, and the 

 amounts fed per cow daily. 



During the 3 years that alfalfa has been grown it has yielded an average of 

 1,328 lbs. of protein per acre. During the periods that alfalfa was fed there 

 was a decrease in milk fiow, although there was an increase in digestible pro- 

 tein fed. The greatest proportion of increase in the milk flow was noted when 

 dry matter and green forage were increased but the protein diminished. " It 

 can not be said that milk production depends upon the quantity of any one of 

 the three — protein, dry matter, and green forage. The amount fed does not 

 seem to bear any definite relation to the amount refused. An attempt was 

 made to feed the cows according to their appetite, and except in the case of 

 rj'e and of corn the amount refused was so small as to be of little importance." 



Cooperative dairy investigations, P. N. Flint and J. E. Doeman (Georgia 

 Sta. Bui. 80, pp. 11,3-172, figs. 13).— K report of the records of four herds as 

 obtained on dairy farms of the State in cooperative work with the Dairy Divi- 

 sion of this Department. 



" The best cow produced in 1 year 9,257 lbs. of milk and 544.39 lbs. of butter. 

 The poorest cow produced in 1 year 1,589 lbs. of milk and 88.02 lbs. of butter. 



" The best herd produced an average of 4,873 lbs. of milk and 319.02 lbs. of 

 butter per cow. The poorest herd produced an average of 3,G53 lbs. of milk and 

 221..3G lbs. of butter per cow. The average production of all herds recorded 

 was 4,385 lbs. of milk and 276.03 lbs. of butter per cow. 



" The cost of producing a pound of butter varied from 10.07 cts. in the case of 

 herd D to 15.3 cts. in the case of herd C. The cost of producing 100 lbs. of 

 milk varied from 65.9 cts. in case of herd D to 94.2 cts. in the case of hered C. 

 The average value of the product of the herds was $889.77, cost of feed $35.88, 

 and profit $53.89."
