The financial, operational and managerial benefits of Ceres Tag ear tags are significant, according to Kenneth Irons, managing director at Precision Farming.
Unfortunately the reverse also happens: the top performing results get dragged down into the general population. This is fine when we are only interested in trends in the status quo, but the dairy industry today needs change.
The dairy industry faces a number of challenges – environmental, welfare and profitability to name a few.
But change is not driven by averages; it is driven by the statistical outliers – those farmers trying something different in all or part of their farming systems.
Trying to predict the future is not a perfect science but it is reasonable to expect that environmental standards will be tighter, and in particular N leaching limits will need to be lower, animal welfare standards will be increasingly monitored by the public and profitability needs to be maintained in the face of highly variable payout.
Production increases of 40% in the last two years (to 2200kg MS/ha), N leaching levels dropping 25%, grass harvest over 18t/ha, stocking rates of seven cows/ha with no pasture damage, costs under $3.00/kgMS, high yield crops produced solely on effluent, simple high input systems – these are statistical outliers hidden by the industry use of averages.
These statistical outliers are all being achieved on a number of farms with HerdHomes shelters and, as I’m sure, they are being achieved under different farm systems also.
These HerdHomes farms are following neither a traditional NZ grazing method nor a traditional European fully housed system; they are developing a hybrid system which utilises the best of both worlds by providing shelter to cows when necessary to protect the cows or pasture or both.
This allows the farmer to focus on efficiently growing and harvesting the highest tonnes of DM/ha possible. In a number of cases this is a mix of crop and pasture with pasture harvest yields higher due to a focus on limiting damage and maintaining the grass in an active growing stage. This is achieved by the cows themselves: giving them access to shelter during poor weather means they will leave the paddock themselves, saving the paddock from greater damage.
Having flexibility of feed options also means farmers can match demand far more evenly, and the cows use the feed more efficiently when out of the wet, cold or heat in some areas of the country.
Effluent capture is simple on these properties and is then treated as a valuable fertiliser resource, returned to the paddocks to maximise use of the nutrients and minimise environmental runoff. In a number of cases this reduces the need for any external phosphate or potash.
When wrapped together it can be a very efficient growing platform, recycling resources via feed efficient cows which allows strong profitability from a long term sustainable system.
Or of course you can be average.
