An Ayrshire cow, Crocus, is reported to have given over 

 45 tons of milk during her 17 years of life. Another Ayrshire 

 cow, Annie Bert, is reported to have given over 45 tons of milk 

 during twelve lactation periods. She also had a record of nearly 

 2 tons of butter. The University of Missouri had a Jersey cow, 

 Hope of Ramapo, that in 17 years produced 78,585 pounds of 

 milk, 4,147 pounds of butter, and 15 calves, thus bringing 

 $1,341.72 into the treasury. The noted Jersey cow, Jacoba

 pounds of butter-fat. Another noted Jersey, Sophie 19th. of 

 Hood Farm, in 6 years produced 75,920 pounds of milk and 

 4,433 pounds of fat. Lily of Willowmoor, an Ayrshire owned 

 in the state of Washington, produced 84,991 pounds of milk 

 and 3,362 pounds of fat in 5 years. The most notable long- 

 distance record is that of the Holstein cow Tilly Alcartra, owned 

 in California, that has produced in 6 consecutive years a total 

 of 4,913 pounds of butter-fat and 156,776 pounds of milk.
