From Long Days to Real-Time Updates: “Nothing Slips Through the Cracks”
Trevor Shanahan – South-West Victoria, Australia

Gone are those long, tiring AI days, says Trevor Shanahan, who started using CowManager in February of 2021. A fourth-generation dairy farmer, Trevor, his wife Sarah and parents Pat and Trish, are all actively involved on the farm. The Shanahans milk 250 to 300 cows at Koroit in South-West Victoria and employ two part-time milkers. They have two daughters and Trevor thinks one of them might be interested in dairying later on.

“The ear tag is easy to get on and off and it’s less intrusive than a collar. We chose CowManager mainly for the Fertility module, but we have the Nutrition and Health modules as well. CowManager gives us more accurate timing of heats and we can AI accordingly. It gives us greater certainty when using sexed semen and makes it more effective and economical. Joining is less stressful; it sorts itself out. There are no big AI days like there were when we used hormones. We let them cycle naturally and we can manage our workload better.” 

The Health and Nutrition alerts on CowManager picks up cows that are struggling, often well before a problem might be noticed by the farm team. It monitors temperature and rumination and allows early intervention before conditions like mastitis and pneumonia become critical. “It’s good when we’re out and about. If a cow hasn’t moved overnight, we get an alert and can treat her first thing. It’s an easier way of doing things and it allows us to pay more attention to the care of individual cows. We have better control. We can keep an eye on them, and nothing slips through the cracks.”
