to feed l)eet pulj) ir is ht'st to give siiuill (j[UMntities at first and 

 increase the amoiuit gradually as the cow's appetite permits. 



The First Experiment 1898-99. 



The plan of this experiment was to feed the beet pulp in alter- 

 nating periods with corn silage, and to feed about the same amount 

 of pulp daily as of silage to the individual cows. Because of the 

 greater amount of dry matter in silage this resulted in the smaller 

 cows consuming twice as much hay when fed pulp as when on silage 

 and with the further result that practically equal amounts of dry 

 matter were consumed whether the cow ate silage or pulp. 



The grain fed consisted of eight pounds per head daily of a mix- 

 ture composed of two parts of gluten feed, two parts of wheat bran 

 and one part of cotton seed meal. The milk was weighed at each 

 milking and composite samples taken which were tested for fat con- 

 tent each week. A description of the cows as to breed, age, num- 

 ber of days in milk and weight follows : 



Ada, 31-32 Holstein. , 

 Cherry, Grade Jersej^ 

 Kate, 7-8 Holstein , . 

 Mollie, 15-16 Holstein.

The weekly record of each of these cows as to the amounts of 

 different foods consumed and of milk and fat produced together 

 with the dry matter consumed per 1,000 pounds daily and the num- 

 ber of pounds of dry matter required by each to produce one hun- 

 dred pounds of milk and one pound of fat is found in table 1. The 

 experiment began on December 6, but the first five days were con- 

 sidered preliminary and the records as given in the table begin with 

 December 11.
