    NIS helps keep middle ground milk contact on track

One Wiltshire estate is making the most of the middle ground milk market by tightly matching the requirements on its contract while using NIS to help boost intakes and yield…

When a profitability ‘tipping point’ was reached five years ago with the dairy herd at Stowell Farms near Marlborough in Wiltshire, estate manager Gavin Davies faced a choice of reinvestment or selling the cows. The decision to expand was made, and now with the herd three times the size and yields averaging 10,000 litres, his aim is to maximise margins from the estate’s middle ground milk contract by driving yields while keeping cows in good health.

Gavin explains that although the role of a dairy herd on an estate such as Stowell is broader than it would be on a specialist unit, the enterprise still has to turn a profit in its own right.

“The dairy herd plays a more holistic role in a large integrated farming business – utilising homegrown by-products and providing rotation opportunities and manure to support the arable operations,” he explains.

With 1,500 acres of arable and 1,500 sheep, there are a number of ways in which the enterprises can complement each other, with the latest addition being an anaerobic digester attached to the dairy with the digestate going back on to arable land.

Firstly it increases intakes of forage fibre because it doesn’t have the ‘gut-fill’ problems associated with chopped straw. But it also improves diet consistency by being easier to mix in the feeder wagon, reducing sorting and overcoming any quality issues with the estate’s own straw supply following a challenging harvest. The cows are settled on it too and aside from these benefits, it usually stacks up cost-wise.

At the moment the ration premix consists mainly of soya, maize distillers grains and soya hulls with minerals and molasses. NIS is added at 2kg for the high yielders and 1kg for later lactation cows. While there is some movement between comparative inclusion rates of soya hulls and NIS in the high yielding ration as the price of straights fluctuates, James is minded to keep NIS in at a minimum of 1kg for high yielders because of the other contributions it makes.

“I feel NIS does a better job of maintaining intakes in very high yielding cows that are on the edge for acidosis,” James explains. “So we now tend to ‘titrate’ the quantity required against what the cows are telling us. There’s a base of 1kg in the blend and then we float another 0.5-1kg on top of that depending on the dung and intakes.

“Managing the butterfat content is very important on this type of contract as under 3.5%, Gavin suffers heavy penalties, but if we go over 3.5% he doesn’t get sufficient bonus payments to compensate for the probable fall in volume.”

This, says James, is why it’s preferable to manage butterfat without resorting to C16. “The trick is to keep the cows on a stable, consistent diet, then from there, manage the fat levels by tweaking the ratios of other elements both in overall quantity of starch, sugar and NDF but also quality of NDF. NIS is an effective way of increasing digestible forage fibre without suffering the problems associated with chopping and feeding straw.”
