IFF has introduced Omni-Bos™ PHY, a novel phytase enzyme developed specifically for dairy cattle nutrition to enhance nutrient availability and feed conversion rates.

The biological feed additive unlocks bound nutrients within existing feed components, allowing dairy cows to extract greater nutritional value from standard rations. The ingredient will undergo an initial commercial rollout across the Middle East, Africa, and Asia-Pacific regions.

The launch addresses production economics at a time when global milk output is projected to expand by 2% annually over the coming decade. With feed representing one of the highest ongoing variable costs in commercial dairy management, improving feed conversion efficiency serves as a central lever for managing margins and environmental targets.

Overcoming Digestive Barriers in Ruminant Nutrition

Phytate, an anti-nutritional compound present across common grain and plant feedstuffs, binds essential minerals and proteins, limiting their bioavailability during digestion. While commercial phytase enzymes have been widely deployed within monogastric swine and poultry feeding programmes for decades, adapting the technology for ruminants has historically presented formulation challenges.

Conventional phytase additives are typically degraded or inactivated within the complex rumen environment before reaching the abomasum, where enzymatic phytate breakdown can occur. Omni-Bos™ PHY was engineered to maintain structural stability under ruminant digestive conditions.

"We believe the future of dairy nutrition is helping cows receive more value from the nutrients in their feed," said Regina Cortada, Vice President, Animal Nutrition & Health for IFF Health & Biosciences. "Our research challenged the long-held assumption that dairy cows fully utilise the phytate contained in feed. We found that phytate breakdown is often incomplete, leaving valuable nutrients unavailable to the animal. Omni-Bos PHY was developed to unlock those nutrients and help producers improve feed efficiency, support sustainability goals and increase profitability."

Ester Vinyeta, Innovation Director, Animal Nutrition & Health for IFF Health & Biosciences, added: "Traditional phytase enzymes were not designed to withstand the unique digestive conditions of dairy cattle. Omni-Bos PHY was specifically developed for ruminants and is designed to remain active where it can unlock nutrients that would otherwise remain inaccessible. This enables dairy producers to extract more nutritional value from existing feed ingredients while reducing nutrient losses."

Validated Nutritional Performance and Digestibility Trials

By releasing native phosphorus, protein, and trace minerals bound to phytate molecules, the enzyme reduces the formulation requirement for inorganic phosphorus supplements and rumen-protected amino acids. The mechanism also expands opportunities to incorporate lower-cost alternative protein ingredients without compromising digestive performance.

In trial evaluations conducted during the product's development phase, Omni-Bos™ PHY lowered undegraded phytate in the abomasum by approximately 70% compared with an unsupplemented control diet.

Controlled trials in lactating dairy cows demonstrated measurable gains across core nutritional metrics:

Phytate and Phosphorus Breakdown: Significantly enhanced phosphorus and phytate digestibility throughout the digestive tract.

Macronutrient Uptake: Elevated systemic digestibility of dietary crude protein and calcium.

Environmental Excretion Reductions: Decreased excretion of unutilised phosphorus and nitrogen into manure streams, lowering the environmental load of dairy operations.

Application Formats and Distribution

Omni-Bos™ PHY is formulated for flexibility across standard commercial milling and on-farm mixing setups. The enzyme additive is validated for direct inclusion into compound concentrates, vitamin and mineral premixes, and farm-level total mixed rations (TMR).

Commercial availability will initially focus on feed manufacturers and dairy producers across regional markets in the Middle East, Africa, and Asia-Pacific, with wider geographical registrations expected to follow.
