lbs. straw. The yields of butter are calculated froin the average yields 

 of butter fat by means of tlie following formula (Fjord's^ : Yield of 

 butter per 100 lbs. of milk = (per cent fat - 0.22) x \\^. 

 The average results per cow daily are as follows :

The data for the percentages of fat do not appear to bear any relation 

 to the intensity of feeding. The yields of milk and butter rise and fall 

 very regularly with the number of food units fed. This is especially 

 apparent from the average data for each group of three. 



Composition of Banish milk. — In thefoHowing table will be found the 

 average composition of the milk produced on the nine Danish estates 

 mentioned in the above table: 



Average chemical composition of millc produced on Danish estates. 



All experiments conducted since 1887 are included in the summary. 

 The determinations made show but small variations in the milk i)ro- 

 duced on the same estates from year to year. All experiments were 

 con<luct(^d during the winter, in the majority of cases between Novem- 

 ber and June. 



The average composition is also given of the various feeding stuffs 

 used in this cooperative experiment. — F. w. woll.
