Cheryl Farrar

Rearing Specialist (South Island)
Based in mid-Canterbury, Cheryl provides technical and sales support to our South Island farmers. She’s a former dairy farmer and calf rearer with several years’ experience in multiple farm service businesses.

Her understanding of the challenges and objectives on farms all-round the South Island makes her an asset to the AgriVantage team and hopefully to your business too.

Cheryl’s story starts on a dairy farm at Reefton on the West Coast, where she grew up. She began her career as a dairy farmer at Mosgiel, milking 1,200 cows. She also reared calves for several years.

Since then, Cheryl has continued to relief milk while also working all-round the South Island as Sales Consultant for Fiberfresh, Territory Manager for CRV and more recently as Technical Sales Consultant for Milkbar.

Her time at CRV and now with AgriVantage appeals to her interest in breeding and rearing animals to maximise their genetic potential.

“It’s great to be part of a business that is focused on rearing healthy animals, selling products that are scientifically developed and proven effective. I am passionate about these products and helping farmers to use them to best effect.”

Cheryl stresses that she does not take a one size fits all approach. “Finding solutions for individual farms is what I am about.”
