GETTING READY FOR WINTER 47 • OCT/NOV 2018 Autumn drilling offers opportunities to bridge forage gaps Autumn 2018 offers many dairy farmers more opportunity than usual for late-season establishment of perennial or hybrid ryegrass, with leys drilled in the coming weeks offering the potential to accelerate the rebuilding of depleted forage stocks. THIS was the message from forage experts Germinal at UK Dairy Day, where the company highlighted an early maize harvest and prolonged warm soil tem- peratures as reasons for planning additional reseeding. “The hot, dry summer has ham- pered grass growth and caused forage shortages, but it’s also resulted in an accumulation of heat units that we are predicting will bring forage maize maturity forward by two to three weeks in many areas,” said Germinal GB na- tional agricultural sales manager Ben Wixey. “There will therefore be more time this autumn to es- tablish grass after maize, and we also expect soil temperatures to stay warmer for longer, extending the period when grass and clover can be sown successfully. “Short term Italian ryegrass or Westerwolds are the norm where drilling is possible after maize, but this year the wider window will bring perennials and hybrids – possibly with white clover – into the reckoning. These longer-term ryegrasses will offer better quality forage over a longer period, so may well be a more versatile solu- tion for anyone seeking ways to rebuild their forage stocks.” Germinal’s expectation for an earlier maize harvest is based on data recorded at their own research station in Wiltshire, where average dry matters across a range of varieties in trials have already reached the 30–32% DM required to trigger harvest. “We’ll be harvesting our maize plots during the week of UK Dairy Day, which is a full two weeks ahead of expectations for the varieties we have in trials,” said Germinal GB technical trials man- ager Dr Jo Matthews. “With the heat unit accumulation that we’ve seen across the country, farmers should now be monitoring their crops closely as maturity is likely to be advanced in a lot of cases. “We are seeing a lot of variabil- ity this year, however, not only across the country but also within fields. Crops on heavier soils have generally fared better during the dry spell, but it’s unwise to make any assumptions and there’s no substitute for getting out into the crop, taking representative sam- ples and checking the dry matter of whole plants.” Germinal advises that dairy farm- ers considering autumn drilling of grass leys, whether after maize or otherwise, should ensure they create conditions that will allow good soil-to-seed contact and that there is enough moisture. www.abccomms.co.uk FORAGE BUDGETING CRITICAL THIS YEAR Despite grass availability finally increasing, most producers are still facing a winter forage shortfall and therefore careful planning is required to stretch out silage. “A lack of available grazing for the major- ity of the summer means many farmers have been buffer feeding for a longer period than usual,” explains David Jones, feeding specialist with InTouch. “With very little forage left over from last year due to delayed turnout, a significant propor- tion of this year’s silage has already been fed.” As a result, winter feeding is going to present a challenge, says Mr Jones, and producers need to act now to avoid their forage running out. “The first step is to measure how much forage you have and budget accordingly. By measuring silage stocks and testing quality, you can determine how much you have available on a dry-matter (DM) basis. This can then be allocated to the number of stocks on-farm, based on a normal winter-feeding period, and will flag the level of shortfall. It’s all about balanc- ing supply and demand,” he says. If silage stocks are not enough, Mr Jones advises producers to source additional feed as soon as possible, as prices are expected to rise, and availability could be limited. “When buying forage replacers, farmers should buy according to the cost of a tonne of DM, as feeds that appear good-value for the season can actually be very expensive if they have a high moisture content,” he says. Mr Jones also warned that rations will require careful balancing to ensure that all nutritional requirements are met. “While straw and hay are fairly good-val- ue in DM terms, appropriate protein and energy sources will be required to make up the nutritional gap.” He adds that the use of InTouch technolo- gy can help farmers budget their forage. “The InTouch system is based around a smart weighing device fitted to a diet feed- er,” says Mr. Jones. “It guides the operator through a specially-calculated loading order, quantity of ingredients and process- ing time, helping to optimise feed efficiency and cut down on waste.” In addition, the system also takes stock of the feeds available. “The stock-take function of InTouch shows how feed stocks are being eroded daily, and will therefore, flag potential shortfalls. While producers should avoid major dietary chang- es, this allows rations to be tweaked and alternative feed sources to be incorporated to avoid completely running out of forage. “If forage stocks were to become fully de- pleted, it would force drastic dietary changes, which alongside having a negative impact on stock performance would lead to a significant hike in feed costs,” he adds. “It’s estimated that producers could already face an increase in the cost of production of around three pence per litre, so forward planning and increased feeding accuracy will be even more important to maintain margins,” concludes Mr Jones. www.alltech.com/news.
