Plantain rethink at demo farm
The Lincoln University Dairy Farm (LUDF) is rethinking its approach to plantain, in the face of continued difficulty in realising its expected benefits.
About 320 dairy farmers at a focus days heard how LUDF has produced milk solids for $3.50/kg farm working expenses (FWE) or less -- down from $4.28 and $3.87 in the two previous seasons.
The farm also boasts yields better than 1800kgMS/ha and 520kgMS/cow on imported dry matter feed of only 126kg/cow.
The focus day, examining LUDF's end-of-season financial performance, is one of four the farm holds each year in nearby regions Duntroon, Temuka, Ashburton and Culverden. All other focus days are held at the LUDF farm.
While the figures are not necessarily better than those of other farms, Ron Pellow, executive director of Lincoln University's South Island Dairying Development Centre (SIDDC), says there were "gains and opportunities" farmers could adopt.
LUDF was grateful for the co-operation of seven Canterbury farms whose production statistics were a benchmark for LUDF comparison and "to see if we really are as profitable as we think".
middle of that group of farms but the two standout farms have nearly double or double our profitability. So they've done a combination of things that have significantly improved their profitability relative to the rest of our group including ourselves," says Pellow.
"We are getting better all the time at growing more grass with less input, and feeding that grass more efficiently to our herd, to maximise milk produced and sold, and minimise the amount of feed required for other requirements that don't actually generate milk."
Pellow says a major focus for LUDF is nitrate control. "We are probably ahead of the game well and truly, compared with our benchmark farms, but we made a deliberate choice to operate in that space.
"ECan requires, for example, farms in Selwyn/Waihora to make big changes by 2022. We're largely achieving their requirements now. We're showing farmers how they can achieve some of those future requirements and we're maintaining profitability.
"We have a very high-yielding farm. We get good sunshine hours, we've got good soils, good fertility, good pastures. We can put irrigation water on as required but the biggest constraint often is the amount of nitrogen in the system.
"So if we allowed ourselves to have more nitrogen we'd be able to produce more pasture and produce more milk. We'd have higher income, higher profitability. But we need to balance that in respect of the total environmental outcome."
Pellow says one factor impacting LUDF's profitability was its approach to Johne's disease, compared with the two more profitable farms in the benchmark group. Testing the herd and culling the high carriers of Johne's was having a short-term impact but over the next four to six years should result in fewer cow losses, he says.
"Johne's is a common disease but we are trying to significantly reduce our exposure to it by identifying cows carrying it -- what we call high-shedders. So if we can reduce our high-shedders then we can reduce the risk of transmission of the disease to our young stock."
