What do Auckland property prices and this couple’s heifer development program have in common?
In 2009, Grant & Danielle Petterd randomly selected 29 calves out of the 78 replacements born that spring and raised them on the Queen of Calves program. The remaining 49 calves were raised on an identical nutrition program of milk & calfmeal but minus the daily addition of Queen of Calves to the milk.
We were unaware of the Petterd's in-farm trial, and the milk production & survival outcomes, until four weeks ago. Click below to read the full story.
