Record of the Station Dairy Herd 



AND 



THE COST OF MILK PRODUCTION. 



By J. B. LiNDSEY. 



FOREWORD. 



Since 1896 the experiment station has kept a herd of from six to 

 twelve cows primarily for the purpose of studying the relative values 

 of coarse and of concentrated feedstuffs upon growth and milk pro- 

 duction, and also for investigating the effect of the different groups 

 of nutrients upon the chemical character of the milk fat. With such 

 objects in view it has, of course, not been possible to ascertain the 

 complete cost of milk production. An exact record, however, has 

 been kept of the food consumed by each animal in the herd and of 

 the composition and amount of the milk produced. It is believed 

 that the data accumulated are of sufficient importance to warrant 

 publication. 



Errata. 



After this bulletin was printed, one mistake in copying and a few small errors were 

 discovered due to faulty work in mechanical adding. Though the consequent mistakes 

 are not sufficient to in the least invalidate conclusions, they are here noted : 



Page 6, Cow Blossom, 1899, column i, in place of 6631, read 22 11. 



Page 27, Table IX, last column ; in place of ir.49, read 15.06. 



Page 9, Table If, errors in calculation corrected make total grain consumed 

 264,988 pounds; corn stover, 37,442 pounds; molasses, 2,048 pounds; oats, 1,070 

 pounds. Total food cost should be $11,690.16 in place of $11,794.80 and food cost 

 per cow in Table III should be 89.24 in place o£ 90.04; hence the food cost of one 

 quart of milk (page 17) should be ^.^^ cents in place of 3.35
