Dairy and Cattle Barn Biosecurity
Cattle operations combine housing, pasture, calf rearing and milking, each with its own pests and hygiene rules. Flies and ringworm drive most housing complaints, ticks drive pasture pressure, and milking parlor sanitation is governed by milk regulations.
Flies and larval habitat
Stable flies breed in wet mixtures of hay, manure and urine at round-bale feeders, calf pens and bedding packs; house flies breed in manure and feed spills. Stable flies bite and reduce weight gain and milk yield. Weekly removal of spilled feed and wet bedding, parasitoid releases and targeted larvicides reduce pressure. Adult sprays alone select resistance. Larva BioControl premise use against manure larvae is in development pending label amendment.
Ringworm, calves and hygiene
Trichophyton verrucosum spreads in calf groups through contact with pens, gates and equipment, with spores persisting for months. Calf hutches and pens need removal of bedding, washing and disinfection between calves. Water troughs develop biofilm and algae and should be scrubbed and sanitized regularly. Footbaths at entry points and dedicated boots between sick pens and clean areas limit spread. Cleaning trough water also improves intake, which supports production. Isolate new calves until checked for lesions.
Ticks and milking rules
Cattle on pasture meet ticks along wood edges and brush; yard zoning and vegetation management reduce contact, and our tick product is in development with premise and perimeter scope only. Milking parlor and milk house sanitation must meet the Grade A Pasteurized Milk Ordinance or national equivalent, which restricts which chemicals may contact milk equipment. Vetpure Disinfectant is used only as its label allows. Check every label for milk contact and withdrawal statements before use.
Key facts
- Stable flies cost US cattle production an estimated 2.2 billion dollars per year (Taylor, Moon and Mark 2012, Journal of Medical Entomology 49:198)
- Milk equipment sanitation in the US follows the Grade A Pasteurized Milk Ordinance (FDA, Grade A Pasteurized Milk Ordinance)
- 1% geraniol applied to cattle reduced Hyalomma tick counts by 98.4%, 97.3% and 91.3% at days 7, 14 and 21 (Khallaayoune et al. 2009, Parasite 16:223)
How our delivery technology applies
Cattle premises are large and exposed to weather, so short-residual actives need frequent reapplication. Encapsulation addresses two needs here: holding chlorine dioxide stable in solution for up to one month for recurring pen and trough sanitation, and extending the field residual of volatile actives such as geraniol for perimeter tick work, where neat oils last a few days.
Dairy and beef operations can apply to host fly larva or tick perimeter trials.
