Producing high feed value silage

Tips & Tricks Ireland

• High feed value silage reduces concentrate requirement during pregnancy
• Silage feed value must be determined by laboratory analysis to develop a nutrition plan
• Each 5% increase in DMD increases:
                                                          1. lamb birth weight by 0.25 kg
                                                          2. ewe weight at lambing by 6.5kg
• Target 75% DMD
• Ensile leafy herbage to produce high DMD silage
• Spread the grass to achieve a rapid wilt
• Wilt to approximately 25-30% DM
• Ensile after approximately 24 to 36 hours after mowing
• Ensile rapidly to provide anaerobic conditions for optimum fermentation
