Understanding udder health
Last month we talked about why dry cow management is critical, though often overlooked. This month I wanted to dive further into the dry period’s importance to udder health.
Waikato dairy farmers are well-placed heading into the peak of summer, thanks to favourable growing conditions late last year that resulted in abundant onfarm feed reserves.
However, with warmer, more humid days ahead, SealesWinslow national sales manager Ryan Scholes advises farmers to focus on balancing cow diets and making strategic feeding decisions to keep cows in milk and maximise the strong forecast payout.
“Many farmers have more surplus feed, like grass silage, than they’ve had in recent years due to excellent pre-Christmas growth,” he says. “While this puts them in a good position, it’s important to remember that summer grass can become fibrous, so balancing the diet with more digestible feed is key to maintaining milk production.”
The importance of balanced diets
Farmers feeding fibrous grass silage or older pasture should consider supplementing with a low NDF (neutral detergent fibre) feed that is easier to digest and promotes efficient rumen function. According to Scholes, a feed with a good mix of protein and starch is critical.
Feeding fibrous silage alongside feed that doesn’t digest quickly, it can limit rumen efficiency, he says. “Instead, opt for a feed that ferments well in the rumen, has high metabolic energy (ME), and is compact and concentrated for easy consumption.”
This advice becomes even more critical as the hotter, more humid months approach.
“To maintain rumen efficiency and support milk production, every bite of feed needs to count.”
Managing heat and humidity
With the heat and humidity rising, cows expend significant energy trying to stay cool, often leading to reduced feed intake. Providing compact, high-ME feeds that cows can consume easily and efficiently during these challenging conditions is essential.

“When cows eat less in the heat, you need feeds that deliver high energy in a small package,” he says.
Transitioning to OAD
Many farmers are also starting to think about transitioning to once-a-day (OAD) milking. This change can help preserve body condition and reduce stress on cows during the hot, humid months. However, Scholes cautions farmers to ensure there’s suitable feed available in the shed to maintain milk production.
“Having something easily digestible and high in energy is critical for cows on OAD milking. It’s about keeping them productive while preserving their condition for the next season,” he says.
Keeping cows in milk longer
With no more advance payments for Fonterra farmers, Scholes advises them to keep their cows in milk as long as possible to maintain a steady income stream while preparing for the next season.
“Keeping cows in milk longer ensures you’re getting the best return on this season’s payout while maintaining their condition. It’s a balancing act between getting production now and setting yourself up for a strong start to the next season.”
