Top results for this dairy farm – no bull!

Owen & Cathy Copinga have seen some big changes on their Southland farm since their herd were all fitted with Allflex collars and that’s no bull…literally. The collars have assisted the couple to farm more effectively and enabled Owen to do 100% artificial insemination and go bull-free for the first time.


Owen & Cathy run split-calving, on their Southland dairy farm. Their 650 Holstein Friesians allow them to supply Fonterra year round. However, it also means they are calving for a total of 20 weeks a year and traditionally spent a lot on heat detection aids - such as tail paint or scratch off patches.


Identifying cows on heat used to be a time-consuming task for Owen and Cathy. The application of tail paint and scratch pads “was another job someone had to do”, explained Owen. With time already in short supply, daily applications were a constant struggle. Having had enough of these time consuming and inaccurate heat detection methods, Owen and Cathy fitted the collars in the wettest winter they had experienced in 20 years. However, despite the poor growing conditions the farm managed to lower its empty rates by 5%.


The collars monitored the herd’s rumination and activity, allowing Cathy and Owen to know exactly what animals were sick or in heat - regardless of if they are at home or at the back of the farm. The Allflex programme also automatically added cows which had not cycled 35 days after calving to ananoestrus group.

“Last spring was probably the first time we were able to proactively manage non-cycling cows - because we had real-time, accurate information”, proclaimed Owen. The collars also ensured cows having silent heats were picked up. This has enabled Owen to do 100% artificial insemination and go bull-free for the first time. “The staff certainly do not miss having bulls around”, he laughed. “For a number of cows, there are no visual signs whatsoever that they’re cycling, but when I put my hand inside the cow, I can feel that she’s ready to be mated”.


The Allflex programme has also helped improve sexed semen conception rates. “We use a lot of sexed semen, but it’s vitally important that you get the timing of the insemination correct”, explained Owen”.


The (Allflex) system automatically colour-codes heats, so a farmer can easily tell how long it’s been since a cow’s had a standing heat”. The programme is compatible with the Copinga’s automated drafting software. This allowed information from the collars to be downloaded as cows walked past antennas on the way to the milking shed. As the cows exit the50-bale rotary, any with heat or health alerts are automatically drafted.


“We wanted some extra technology that could help us identify cows that were struggling shortly after calving, but were undetectable to us”. Protocols have been put in place for staff to check cows drafted for a health alert. “We had a freshly-calved heifer in the spring who triggered a health alert. We checked her milk and there were no visible signs of mastitis”, he said.  “However, when we examined the milk more closely, you could see she was developing mastitis. It enables us to treat the infection earlier”.


The Copingas have a big focus on animal health and nutrition. “We only had one cow go down with milk fever last spring,” says Owen. “The collars helped us identify cows that needed a preventative bag of calcium borogluconate or dextrose. It would trigger an immediate response and the cow’s rumination would be back to normal within 12 hours.” The Allflex system even alerted the team to cows active outside of their usual times, such as breaking out on a crop at night. “We would not have picked up those problems that early without the help of the collars. They made a huge difference.
