The BEWI-FATRIX® range of rumen-protected amino acids, developed by BEWITAL agri, is now available to UK and Ireland dairy producers through Azelis’ distribution.
BEWITAL agri’s range of rumen-protected amino acids, the BEWI-FATRIX® product range is available for UK and Ireland dairy producers, distributed by Azelis. The product range is designed to boost milk yields, support milk protein synthesis, and reduce nitrogen excretion.
Developed by German animal nutrition specialists BEWITAL agri, the BEWI-FATRIX® range uses a special cryotechnology to protect essential amino acids like lysine and methionine from rumen degradation. This ensures targeted delivery to the small intestine, where they are most efficiently absorbed and utilised by the animal.
PRECISION NUTRITION
“Supplementing low-crude-protein diets with amino acids provides a smarter solution for reducing the environmental footprint of the dairy sector” explains Leia Trotman, Ruminant & Equine Technical Sales Manager at Azelis UK. “In many standard rations, methionine and lysine are the first-limiting amino acids. The BEWI-FATRIX® range helps balance amino acid supply with precision and high bioavailability, improving protein efficiency, boosting performance, and supporting sustainability.”
With increasing pressure on producers to reduce soya use, cut nitrogen losses, and optimise feed efficiency, improving amino acid delivery to the small intestine has become a key priority for dairy nutritionists.
“As producers move towards soya-reduced rations and alternative protein sources like rapeseed meal, the risk of lysine deficiency increases,” adds Trotman. “Without an adequate supply of methionine and lysine, milk protein synthesis suffers. Simply increasing crude protein can create inefficiencies, strain metabolism, waste energy and contribute to negative environmental impacts.”
PROVEN PERFORMANCE
Research has consistently demonstrated high bioavailability thanks to the special production process, which embeds amino acids evenly to minimise degradation, rather than enclosing them in a conventional fat coat.
Trials by Schothorst Feed Research show that BEWI-FATRIX® Methionine achieves a rumen bypass rate of 86.4%, with 88% intestinal availability and a bioavailability of 77.4%, offering a highly effective source of bioavailable methionine for dairy cows.
The BEWI-FATRIX® range reportedly provides a science-backed solution that allows producers to reduce crude protein inputs while maintaining or even improving performance. All amino acids within the BEWI-FATRIX® range are embedded in a rumen-stable fat matrix derived from either palm oil or rapeseed oil (RS) – the latter offering a more sustainable option.
Key products in the range include:
• BEWI-FATRIX® Methionine and RS-Methionine
Rumen-protected methionine – critical for milk protein synthesis, liver function, and early lactation performance.
• BEWI-FATRIX® Lysine and RS-Lysine
Delivers digestible, rumen-protected lysine to support milk protein production, especially in soya-free or reduced-protein diets.
• BEWI-FATRIX® LM 101
A combination of intestinal digestible lysine and methionine to increase milk performance and nitrogen efficiency; awarded an Innov’Space Award at the 2022 SPACE Livestock Show in France.
“We’re seeing strong demand from UK producers wanting to fine-tune rations and meet environmental goals,” remarks Leia Trotman. “BEWI-FATRIX® is easy to incorporate into premixes, minerals, or complete feeds and is backed by robust science – making it a practical and effective choice for forward-thinking dairy systems.”
Its UK launch gives dairy farmers access to a targeted, research-proven tool for improving feed precision, reducing environmental impact, and maintaining high-performance herds – at a time of increasing input costs and environmental scrutiny.
Benefits of the BEWI-FATRIX® range have been explained as:
• Optimises amino acid supply and supports liver metabolism,
• Reduces crude protein requirements and improves feed efficiency,
• Supports higher milk yields and improved milk components,
• Helps lower environmental burden from excess nitrogen,
• Free-flowing, slow-release, and easy to handle,
• Consistent nutrient distribution within products due to special production process,
• Concentrated formulations with up to 40% active ingredients.
Azelis highlights that this launch aligns with its long-term sustainability programme, Impact 2030, leading the industry in environmental stewardship, social responsibility, and ethical governance. The programme incorporates SBTi-guided greenhouse gas emission reduction targets and aims to provide customers with greater product transparency for better choices and enable principals to accelerate their sustainability strategies. By enabling more efficient protein use and reducing nitrogen excretion, the BEWI-FATRIX® range is expected to contribute to the programme’s goals of lowering greenhouse gas emissions and promoting sustainable agriculture.
