Virbac

Veterinary Antibiotics

Injectable and oral antibiotic formulations for bacterial infections in livestock, with full AMR stewardship and withdrawal documentation.

Bacterial disease costs East African livestock producers 15-20% of herd value annually. Uncontrolled antibiotic use risks making those losses permanent.

Bacterial infections including respiratory disease, mastitis, foot rot and metritis are among the most common causes of livestock mortality and production loss in East Africa. Virbac Animal Health covers every major drug class needed in livestock practice: tetracyclines, cephalosporins, penicillins and macrolides in injectable, oral and intramammary formats. Jos•Hansen supplies Virbac antibiotics under veterinary prescription with full withdrawal documentation and AMR stewardship aligned to Kenya Veterinary Board requirements.

Veterinary Antibiotics

Resistance-conscious selection

Virbac's range leads with narrow-spectrum first-line options, oxytetracycline for broad coverage and amoxicillin-clavulanate for resistant gram-positive infections, reserving fluoroquinolones and third-generation cephalosporins for culture-confirmed resistant cases only.

Withdrawal documentation

Every Virbac antibiotic is supplied with species-specific and country-specific withdrawal period data, enabling safe management of meat and milk withdrawal and avoiding residue violations at market, dairy plant or export inspection.

KVB prescription compliance

Jos•Hansen supplies Virbac antibiotics exclusively under veterinary prescription through licensed channels, complying with KVB regulations, FAO antimicrobial stewardship guidelines and export certification requirements.

Bacterial disease is East Africa's leading veterinary cost.

Bovine respiratory disease, mastitis, footrot and metritis account for the majority of antibiotic treatment events in East African cattle and small ruminants. Left untreated, bacterial infections cause mortality, permanent udder damage and infertility. Treated late or with the wrong drug, they produce treatment failure, residue violations and wasted expenditure. Structured bacterial disease control requires early diagnosis, appropriate drug selection, correct dosing and documented withdrawal.

Depth across every major antibiotic class.

Engemycin (oxytetracycline 10% and 20%) is the most widely used broad-spectrum antibiotic in East African livestock practice. Excenel RTU (ceftiofur) provides third-generation cephalosporin activity for resistant respiratory and urinary infections. Lincomycin-spectinomycin covers Mycoplasma and gram-positive organisms in pig and cattle respiratory disease. Virbac intramammary tubes cover all four major mastitis pathogens in a single treatment format.

Jos•Hansen builds farm health plans, not just supply orders.

We work with veterinary practices and farm managers to structure antibiotic use: first-line drugs, treatment duration, withdrawal management and culture-based escalation for resistant cases. This reduces total antibiotic consumption, lowers residue risk and satisfies the AMR documentation required by major export buyers and dairy processors. Jos•Hansen maintains the supply records needed for regulatory and buyer audits.
