What cow condition can tell us

A cow’s body condition score isn’t just a measure of how she looks today – it’s one of the clearest indicators of how she’ll perform through the season ahead.

Father and daughter team Richard and Nicole Grayling reflect on what helped set their herd up for the season. And while spring always brings its share of surprises, one thing stands out.

“Body condition score tells you a lot about what sort of season you’re going to have,” says Nicole.

It’s not something the Waikato farming family focuses on for a few weeks before calving. Instead, it’s a year-round tool that helps guide decisions about feeding, stocking rate, pasture management and animal performance. Looking across the herd this spring, they’re already seeing the benefits of the work that started well before the first calves arrived.
 

The season started before calving

Like many farms, the Graylings were managing a balancing act heading into winter. Cows had milked well through autumn, but keeping condition on the herd remained a focus. Looking back now, Richard believes some cows entered winter lighter than ideal.

“We probably milked a little longer than we usually would,” he says. “That pulled a bit of weight off some of the cows.”

Rather than chasing condition at the last minute, the focus became maintaining a steady plane of nutrition and ensuring cows entered calving in as good a position as possible. 

“Once cows lose condition, it can be hard to get it back on quickly,” says Richard. “If they’re light at calving and then you hit a feed pinch, you’re already on the back foot.”
 

Observation made the difference

On reflection, one thing Richard and Nicole kept coming back to was the importance of paying attention. 

The Graylings spend time walking through cows every day. They’re looking for cows that aren’t behaving normally, animals that sit apart from the mob, or those that simply don’t look quite right. Sometimes the clues are subtle. A cow sitting while others graze. A slight drop in condition. An animal that seems out of place. 

Those observations often trigger conversations that help identify issues before they become problems.

“We’re in amongst them every day,” says Nicole. “That’s when you notice things.”

The approach isn’t limited to Richard and Nicole. Staff are encouraged to walk through the herd, ask questions and share what they see. “Everyone looks at animals differently,” says Richard. “If everybody feeds that information into one pool, we all learn together.”
 

Consistency tells its own story

Another thing they noticed this spring was how even the herd looked. 

“When you scan across the paddock, nobody really sticks out,” says Nicole. “All the cows are quite even.” For her, that’s often one of the most reassuring signs.

Not every cow needs to be perfect, but consistency across the herd suggests most animals are coping well with the demands of calving and early lactation. Richard agrees. “If they’re all looking about the same condition, that’s generally a good sign.”
 

Looking ahead to mating

Everything from feed decisions to body condition and pasture management now feeds into mating performance. For Richard, that’s why body condition score remains such a valuable management tool. A cow that calves in good condition is more likely to transition successfully into lactation, recover well and return to mating in a stronger position.

“If we can keep them on an upward plane, it’s going to put more money in the bank at the end of the day,” he says.

The connection isn’t complicated. Healthy, well-fed cows generally cope better with the pressures of the season. Better recovery. Better reproductive performance. Fewer interventions.
 

The real value of body condition score

Ask the Graylings what body condition score means to them, and neither talks about numbers first. Instead, they talk about outcomes. A smoother calving. A stronger herd. Less stress on animals and people. More confidence heading into mating. Looking back on spring so far, Richard believes body condition score remains one of the simplest ways to understand where a herd is tracking.

“We’re always looking at a range of things, but body condition score is one of the measures that helps guide our decisions,” says Richard.
