DairyNZ supports vocational education reforms
DairyNZ is supporting a proposed new learning model for apprenticeships and traineeships that would see training, education, and pastoral care delivered together to provide the best chance of success.
Our recent DairyNZ wintering survey highlighted some notable achievements, including that 80% of farmers have now written wintering plans.
Planning makes perfect
Last winter, 74% of farmers implemented at least five good management practices to support their cows and manage winter conditions. Also, 96% of farmers surveyed said they had strategies to provide comfortable lying conditions for their cows.
Despite this, another finding is that portable trough use and back fencing had a low uptake, which hasn’t increased over the last three seasons. If you’re looking to lift farm performance in 2024, these are two highly beneficial actions to consider.
The benefits of portable troughs and back fencing
I’ve seen firsthand the advantages of using portable troughs and back fencing and encourage all farmers to consider how to make these a core part of winter grazing plans.
The main benefits farmers talk about relate to better soil conditions. Paddocks dry out sooner so you can get equipment in early and get something else growing more easily. And soils are less damaged, so when the wet weather arrives, back fences can be extended or dropped to provide more area for cows to lie on.
If you’re concerned about the added work involved in moving portable troughs, there are some great ‘number 8 wire’ solutions recommended by farmers who have used them successfully.
These include the installation of skis for ease of movement, putting troughs under fences of neighbouring grass paddocks to avoid dragging them through mud, and putting troughs on trailers.
Identify comfortable lying surfaces
Portable troughs and back fencing are an essential part of a great winter toolkit to provide comfortable lying surfaces that allow cows to lie down for as long as they want to. Since cows require a minimum of 8-10 hours of lying time per day, and prefer 10-12 hours, it’s important to make sure conditions are good enough for them to lie down comfortably when they want to.
During prolonged periods of wet weather when paddocks become too wet and muddy, it’s important to have a contingency plan. The range of strategies available include shifting cows to a drier, lower-risk paddock, or using crops positioned in drier or more-sheltered areas for grazing during bad weather.
You could also stand them off in a tree block, or use feed pads/standoff pads, or grass strips in crop paddocks.
I’ve also seen farmers roll out straw for cows to lie on.
Develop your wintering plans with your team so they clearly understand the ‘why’ behind the plan.
The Gumboot Score
So how do you decide when the conditions aren’t right for sufficient lying time?
The gumboot score is a tried-and-true method for responding to winter weather conditions.

However, we’ve heard of a few other quirky, but sensible methods. One farmer told us, “If the mud pulls your red bands off, it’s too wet for the cows to lie on”.
Another says, “If I won’t lie down in that paddock, I shouldn’t expect my cows to lie down in it either”.
Whatever your strategy for identifying a comfortable lying surface, it’s important to have a firm boundary for when you need to provide cows with a more comfortable surface to lie on.
Outline this in your written wintering contingency plan, including your portable trough and back fence strategy, and share it with your farm team so everyone knows when to act.
Farmers with teams tell us that because of the high risks around animal care and environmental requirements, they prefer to manage crop wintering themselves.
But upskilling your team could take some of the pressure off.
If you develop your wintering plans with your team so they clearly understand the ‘why’ behind the plan, you will get better outcomes and they might even have novel solutions to some of the day-today challenges.

Keeping cows comfortable
Cows wintered on crops prefer to lie for 10-12 hours daily. Discover tips to keep your cows comfortable and ensure their wellbeing over winter at dairynz.co.nz/cow-comfort.
