                                        Managing Director Tim Pollock.
                                        “In ten years yield from forage
                                        has fallen by over 700 litres per cow with under 30%
                                        of production in the average herd coming from forage.
                                        This means feed costs have increased by around £70 per
                                        cow. Farmers are more exposed to the increased volatility
                                        in feed prices which is a feature of the feed market.
                                        Producing more from forage is the main way farmers can
                                        offset the impact of rising feed prices.”
                                        The conference is being held at Hartpury College,
                                        Gloucester on Wednesday 2nd March and runs from
                                        9.30 a.m. – 4.00 p.m., including lunch.
                                        “The conference will help farmers develop strategies to
                                        exploit the value of forages and will focus on the various
                                        ways to increase production. An international panel of
                                        speakers will cover subjects including maximising forage
