Novamont and Sila unveil Nutrilox feed additives: up to 33% lower ruminant methane intensity in trials

Novamont, a Versalis (Eni) company, and Sila, a specialist in microencapsulated products for animal nutrition, presented Nutrilox at EuroTier in Hannover (10–13 November 2026), according to adnkronos.com. Nutrilox is a family of feed additives developed jointly by the two companies adnkronos.comadnkronos.comadnkronos.comOpen source ↗. The universities of Milan and Bologna validated it through a series of in vitro and in vivo tests that checked its characteristics and efficacy against the development targets.

Composition and microencapsulation

The range is based on short- and medium-chain fatty acids and essential oils. The fatty acids are produced at Novamont's biorefinery in Porto Torres (Sassari). The company says the process uses a proprietary technology, the first of its kind, designed to exploit the molecular complexity of vegetable oils.

Sila's microencapsulation technology is applied on top of this base. Specific coatings protect the selected active ingredients, improve their stability and bioavailability, and provide controlled, targeted release along the digestive tract.

Product line and results

The stated aim is more precise and effective animal nutrition and better production performance. For ruminants, the companies report a reduction in methane emission intensity of up to 33%, as shown by in vivo studies conducted by the University of Bologna adnkronos.comadnkronos.comadnkronos.comOpen source ↗.

The line currently includes five products [1]:

• Nutrilox Geolin, in EB and PP versions, for different stages of the ruminant production cycle;
• Nutrilox Defence and Nutrilox Performance, developed for poultry;
• Nutrilox Starter, for calves in the early rearing phase.

Alessandro Del Seppia, Head of Biochemicals at Novamont, said Nutrilox combines the fatty acids made in the integrated biorefinery with Sila's microencapsulation science, and that the companies came to EuroTier to offer it to more precise and efficient livestock farming. Maurizio Lorenzon, CEO of Sila, said the product responds to a growing number of farmers asking for quality products with lower environmental impact, and that the two companies showed that production efficiency and sustainability can improve together.
