Germany: research on lactation period

In Germany, research of the university of Rostock during four years with 3000 cows shows that cows that after their first lactation had a dry period of eight weeks instead of six weeks later produce more milk. In 100 days the eight week cows produced 4224 kilogram milk compared to 4155 kilogram milk of the six week cows. In 305 days the eight week cows produced 300 kilogram more milk.
