 The Ohio Experimental Station has published the result of its researches 

 into the daily increase of the Jersey and Holstein-Friesian breeds from 

 birth to calving. The data were collected at the experimental farm, and 

 comprise up to now : 69 series of individual daily observations up to one 

 year; 51 series up to two years, and 37 series up to the first calving. In 

 addition to the increase of weight, there was also noted day b}' day the quant- 

 ity of food consumed and the cost of this food, as well as the total cost of 

 rearing, allowing for the other expenses incurred. 



We sum up in the following table the average data in reference hereto : 



Food consumption during the first year and costs of r eating. 



Consumption of food during the second year and costs of rearing.

An examination of the individual series discloses the fact, which is
