Werner Marx milks 270 crossbred cows on 100 hectares alongside his daughter Amy and son-in-law Nathan producing an average 470kg/MS per cow. The family supplies Mataura Valley Milk, part of the a2 Milk Company, and has been working to transition their herd to fully a2 over the past five years.
“I could see where things were going with a2 and that it would offer a premium payment if we could transition our herd to a2 milkers,” says Werner. “We have been successfully breeding for a2 producing cows with CRV semen for the past five years.”
Last season he decided to try CRV’s sexed semen straws to see if he could boost his rate of a2 heifers. The results were so good he’s planning on using sexed semen across most of his herd this mating season.
“We used 50 straws right at the start of mating season last year so we could have a second chance if they didn’t get in calf, but 36 out of the 50 cows got in calf first time,” says Werner.
