Managing severe respiratory outbreaks, bovine respiratory disease (BRD) complexes, swine respiratory disease (SRD), and acute bacterial infections in beef cattle, non-lactating dairy cattle, and commercial swine herds requires a high-potency, broad-spectrum antimicrobial with rapid bactericidal tissue penetration. When livestock encounter aggressive gram-negative and gram-positive pathogens such as Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and Actinobacillus pleuropneumoniae, infections progress rapidly across crowded housing units, causing severe lung consolidation and high mortality.
Left unmanaged, bacterial respiratory disease epidemics lead to high herd morbidity, permanent pulmonary scarring, heavy treatment failures, and severe economic losses.
Relying on outdated, bacteriostatic antibiotics during aggressive field outbreaks fails because they only slow bacterial growth instead of destroying pathogens at the cellular level.
To deliver immediate, concentration-dependent bactericidal eradication across heavy livestock populations, professional veterinarians and commercial producers rely on gold-standard fluoroquinolone injectables. Enroflox 100 is a premier, professional-grade sterile injectable solution containing $100\ \text{mg/mL}$ of enrofloxacin. Packaged in convenient multi-dose bottles, Enroflox 100 delivers powerful antimicrobial activity engineered specifically for beef cattle, non-lactating dairy cattle, and swine.
Enroflox 100 delivers a targeted biochemical mechanism designed to inhibit DNA replication and destroy pathogenic bacteria rapidly:

Enrofloxacin ($100\ \text{mg/mL}$) is a broad-spectrum fluoroquinolone antimicrobial agent. It acts by inhibiting bacterial DNA gyrase and topoisomerase IV enzymes, which are critical for bacterial DNA supercoiling, replication, and transcription. By blocking these enzymes, enrofloxacin halts bacterial multiplication and induces rapid cell death.
High-Volume Volume of Distribution: Enroflox 100 achieves exceptionally high concentrations in pulmonary tissue, bronchial fluids, liver, and kidney, ensuring rapid neutralization of encapsulated respiratory pathogens.
Single-Dose and Multi-Day Flexibility: Formulated for flexible dosing regimens, allowing rapid therapeutic intervention during herd health emergencies.
Enroflox 100 is an essential therapeutic and metaphylactic tool for beef feedlots, cow-calf operations, non-lactating dairy units, and commercial swine farms:
Bovine Respiratory Disease (BRD / Shipping Fever): Treatment and control of BRD associated with Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and Mycoplasma bovis in beef and non-lactating dairy cattle.
Swine Respiratory Disease (SRD): Treatment and control of bacterial swine respiratory disease associated with Actinobacillus pleuropneumoniae, Pasteurella multocida, Haemophilus parasuis, and Bordetella bronchiseptica.
Herd Metaphylaxis During Outbreaks: Rapidly halts the spread of respiratory disease across incoming feedlot calves or nursery swine units during high-stress transition phases.
To guarantee absolute safety, proper bioavailability, and tissue compatibility, Enroflox 100 must be administered strictly according to approved species and route guidelines.
1.Inspect Vial & Disinfect Septum:Aseptic Setup.
Inspect the multi-dose bottle to ensure seal integrity. Swab the rubber stopper thoroughly with an antiseptic alcohol pad before drawing the solution into a sterile syringe.
2.Confirm Species-Specific Route:Route Selection.
Select the correct route carefully:
Cattle: Administer via subcutaneous (SQ) injection in the neck.
Swine: Administer via intramuscular (IM) injection in the neck muscle.
3.Calculate Precise Body Weight Dose:Dosage Calculation.
Calculate volume strictly by body weight. Standard cattle BRD single-dose therapy is $7.5\ \text{mg/kg}$ ($3.4\ \text{mL}$ per $100\ \text{lbs}$), while swine SRD is dosed at $7.5\ \text{mg/kg}$ ($2.27\ \text{mL}$ per $100\ \text{lbs}$ body weight).
4.Observe Site Volume Limits:Injection Limits.
For heavy cattle, split large doses across multiple injection sites so that no more than $10\ \text{mL}$ is administered per site.

The table below outlines standard administration guidelines for Enroflox 100 ($100\ \text{mg/mL}$):
| Target Species | Clinical Indication | Standard Dose Rate | Approved Route | Administration Schedule |
| Beef & Non-Lactating Cattle | Bovine Respiratory Disease (BRD) | $7.5\ \text{mg/kg}$ ($3.4\ \text{mL}$ / $100\ \text{lbs}$) | Subcutaneous (SQ) in Neck | Single-dose therapy (or daily low-dose regimen) |
| Beef & Non-Lactating Cattle | BRD Control (High-Risk Herds) | $7.5\ \text{mg/kg}$ ($3.4\ \text{mL}$ / $100\ \text{lbs}$) | Subcutaneous (SQ) in Neck | Metaphylactic single dose upon arrival |
| Swine | Swine Respiratory Disease (SRD) | $7.5\ \text{mg/kg}$ ($2.27\ \text{mL}$ / $100\ \text{lbs}$) | Intramuscular (IM) in Neck | Single-dose or consecutive daily dosing |
Strictly Non-Lactating Cattle Only: Do not use in female dairy cattle 20 months of age or older. Use in dairy cattle of breeding age may cause drug residues in milk. Approved strictly for beef cattle and non-lactating dairy stock.
Meat Withdrawal Period: Always adhere strictly to regional regulatory withdrawal windows. Note: Cattle treated with Enroflox 100 at the single high-dose rate typically carry a mandatory meat withdrawal period of 28 days.
Storage Parameters: Store unopened multi-dose bottles at controlled room temperature between 15°C and 30°C (59°F to 86°F). Protect from direct sunlight and freezing.
