Sugar Beet Pulp as a Food for Cows. 11 



Charts. 



The following diagrams show the variation in average daily yield 

 of. milk and per cent of fat during the two feeding periods. The 

 diagram for each cow is given above her name, the record for milk 

 appearing above that for per cent of fat. Passing from left to 

 right in the chart each division represents one week. Passing 

 upward or downward each space represents one-half pound of milk 

 or one-tenth of one per cent of fat as the case may be. The space 

 between the heavy perpendicular lines represents the period during 

 w^hich beet pulp was fed, i, e., in the year 1898-9 ; with Ada, 

 Cherry and Puby this period was from the sixth to the eighth 

 weeks inclusive, while with Kate and MoUie it was from the first to 

 the fourth weeks, inclusive. In the year 1899 the beet pulp feed- 

 ing period was from the second to the sixth weeks, inclusive. 



A survey of the records shows that the cows did quite as well on 

 beet pulp as on silage. In fact the pulp seems to liave had a stimu- 

 lating effect on the flow^ of milk, as is seen from the records during 

 the first few weeks of feeding pulp in 1899. With the exception 

 of Mollie, 1898-9, and Puby, 1899, the individual cows consumed 

 about equal amounts of dry matter per 1,000 pounds live weight 

 whatever the feed, and each one also required nearly the same quan- 

 tities of dry matter for one hundred pounds of milk and one pound 

 of fat, wdiether the food was silage or pulp. A greater difference 

 in this respect is found in the amount of dry matter required for 

 milk than of that required for fat, as may be shown by making a 

 few averages from the records. In order to secure periods in which 

 the peculiar influence of each food may be seen as clearly as pos- 

 sible, we have made up some averages from the third to the fifth 

 weeks and from the seventh to the ninth weeks, inclusive, during 

 the first experiment, and for the sixth and seventh and ninth and 

 tenth wrecks of the second experiment. The averages thus obtained 

 are here given.
