Rumenco launches new silage additive
Rumenco has launched NovaSile Cool and Stable (NovaSile CS), a new silage additive designed to work across all silage types including grass, maize, wholecrop and legumes.
“NovaSile CS contains two fast-acting lactic acid bacteria that reduce the pH level of a clamp or bale quickly, to protect its nutrient value and prevent against yeast and mould development that can cause silage to heat,” explains Rumenco’s Dr Alison Bond.
NovaSile CS also contains an acetic acid producing bacteria that improves aerobic stability once silage is exposed to oxygen. Having two independent bacteria working in harmony enables NovaSile CS to keep ensiled forage cool and improve dry matter retention when the clamp is opened. The homofermentative and heterofermentative bacterial strains provide complementary properties that keep silage stable and lock in nutrients, helping to optimise feed quality.
NovaSile CS contains the only European Food Safety Authority (EFSA) approved bacteria proven to reduce heating and improve dry matter retention. It does this by converting sugars into more controllable amounts of acetic acid and other anti-fungal compounds that prevent yeast and moulds developing as quickly, especially when the clamp has been opened,” says Dr Bond.
With silage quality and quantity a concern in some parts of the UK, and with feed stocks down for many, 2026 will be a crucial year to optimise forage production. With its ability to improve silage quality, speed up fermentation and provide a higher dry matter and nutrient rich forage, NovaSile CS could be an important solution for many livestock farms next year.
“Bought-in feed is a huge cost to any livestock farm, so maximising homegrown forage and locking in the nutrients is essential for maintaining animal health and profitability. NovaSile CS is a breakthrough in forage preservation and offers a unique silage control formulation that will help keep silage fresher for longer,” says Dr Bond.
NovaSile CS is suitable for all forage types, making it easy to adopt on larger farms that produce maize and wholecrop in addition to grass. The product is available in 200-gram sachets each able to treat 100 tonnes of fresh forage when diluted in up to 7 litres of water. It is best applied during chopping to ensure even coverage and can be applied via both low-dosing systems and standard systems.
