Vilnus FOAM: Lactic Acid and Iodine Combination Pre-Milking Dip

Combining Lactic Acid and Iodine in a Foam Format

Vilnus FOAM is a pre-milking teat dip that delivers both lactic acid and iodine as active disinfectants in a foam application format. The combination provides fast-acting bactericidal activity from the lactic acid component alongside the broad-spectrum coverage of iodine, in a product designed specifically for foam-gun application.

Foam format improves teat coverage compared to liquid dipping: foam clings to the teat skin and teat end, maintains contact longer during the pre-milking lag time, and uses less product per cow than a liquid dip cup because coverage is more efficient. For large dairies and farms where milker labor cost matters, foam pre-milking dips reduce the time per cow while maintaining or improving disinfection coverage.

Iodine in Pre-Milking vs Post-Milking Products

Iodine is most familiar as a post-milking teat dip active ingredient, where high-concentration formulations (3,000–5,000 ppm) provide long-duration teat canal protection. In pre-milking formulations like Vilnus FOAM, iodine is used at lower concentrations suited to pre-milking purposes: rapid bactericidal effect on the teat surface without excess residue that might carry over into the milk.

The lactic acid component in Vilnus FOAM contributes rapid kill of environmental gram-negative bacteria and gram-positive pathogens, complementing the broader coverage of iodine.

Equipment Compatibility

Vilnus FOAM is designed for foam application using standard foam dipping equipment. The Ambic Multi Foamer Plus is a suitable applicator for parlor use. For individual cow checking or smaller operations, the Tudder Micro provides a compact foam dipping tool.

Choosing Vilnus FOAM vs Other Pre-Milking Dips

Vilnus FOAM is the natural choice when:

• Foam application is the preferred or established pre-milking method on the farm
• Dual-active (lactic acid + iodine) pre-milking chemistry is desired
• Herd size and throughput justify investment in foam application equipment

For chlorhexidine-based dual-active pre-milking, Vilnus LACO provides the lactic acid + chlorhexidine combination. For iodine-based post-milking dips in the same product line, the Vilnus F-series products handle post-milking iodine dipping.
