an average increase of about one-half of one per cent from 

 month to month. 



As a rule, a cow will produce more butter during the first few 

 weeks of a lactation period than at any equal subsequent time 

 during the same lactation. 



The general effect of the change from barn to pasture was an 

 increase in both milk flow and per cent of fat for the first two 

 weeks, and for the next three weeks a slight decrease in milk 

 and per cent of fat below the daily average for the last three 

 weeks in the barn. 



During the year 1892 twenty cows produced milk for 62^ 

 cents per hundred weight and fat for about sixteen cents per 

 pound for the food consumed. 



In general, the cows consuming the most food produced both 

 milk and fat at the lowest rate.
