Gebbie’s Maplehurst Farm was started in the 1850s and is now a 5th generation farm. In 1973 there were 35 cows onsite; in 1980,  100 cows; and from ’93 to 2015 they grew ten times in size! Ever since, they have experienced steady growth, with a currently total of 240, down from 375 when they added new milking robots.


Gebbie’s Maplehurst Farm started construction on their complete mix digester in 2011, and it became operational in 2012. Reasons prompting them to add the digester included odor issues and the hope of reducing their fertilizer bill, but also because they were inspired to try something new and innovative.
