Liquid Dewormer for Cattle – Fenbendazole 10% Solution

Fenbendazole 10% Liquid Dewormer for Cattle (100 mg per mL) is a veterinary-recognized anthelmintic formulated to treat and control susceptible internal parasites in beef and dairy cattle. It works by binding to parasite tubulin, disrupting energy metabolism and leading to the elimination of targeted worms.

Fenbendazole is approved for use in cattle under specific labeled formulations and dosing standards established under regulatory guidance from the U.S. Food and Drug Administration.

What Parasites Does It Target in Cattle?

Fenbendazole is used for the treatment and control of susceptible:

• Gastrointestinal roundworms (Ostertagia, Haemonchus, Cooperia species)
• Lungworms (Dictyocaulus viviparus)
• Certain stomach worms
• Some intestinal worms

⚠️ Important: Fenbendazole is not effective against liver flukes.
⚠️ Tapeworm control in cattle is limited and species-dependent.

Parasite susceptibility may vary by region due to resistance patterns.

Symptoms of Parasites in Cattle

Cattle with internal parasite burdens may show:

• Poor weight gain
• Reduced feed efficiency
• Diarrhea
• Rough hair coat
• Anemia (pale mucous membranes)
• Coughing (lungworm cases)
• Reduced milk production

Strategic deworming supports improved herd productivity.

Verified Dosage (10% = 100 mg/mL)

Standard FDA-labeled cattle dose:
5 mg per kg body weight (single oral dose)

1 kg = 2.2 lb
5 mg/kg = 2.27 mg per lb

Since the solution contains 100 mg/mL:

2.27 ÷ 100 =

✅ 0.023 mL per lb (Single Oral Dose)

Administration Guidelines

• Administer orally using a calibrated drench gun.
• Do not rely on water-medication systems unless specifically formulated for that use.
• Always dose according to accurate body weight.
• Underdosing increases parasite resistance risk.

---

Treatment Frequency

• Standard protocol: Single oral dose
• Strategic deworming based on fecal egg counts is recommended.
• Repeat treatments should follow veterinary guidance.

Routine blanket deworming without monitoring may increase resistance.

---

Safety & Breeding Guidance

• Approved for use in beef and dairy cattle at labeled doses.
• Generally considered safe in pregnant cattle when used at the recommended dose.
• Safe for calves when accurately weight-dosed.

Always consult a veterinarian for herd-specific parasite management programs.

---

Withdrawal Periods

Withdrawal times depend on formulation and label:

• Meat withdrawal periods apply.
• Dairy withdrawal varies depending on product labeling.

Always follow product-specific withdrawal instructions to remain compliant.

FAQs

How often should I deworm cattle?

Strategic deworming based on fecal egg counts and pasture exposure is recommended instead of fixed-interval blanket dosing.

---

Is it safe for calves?

Yes, when accurately dosed at 5 mg/kg (0.023 mL per lb).

---

Can it be mixed with feed or water?

Direct oral drenching ensures accurate intake. Mixing with water may result in inconsistent dosing.

---

Is it effective against liver flukes?

No. Fenbendazole does not treat liver flukes. A flukicide is required for that parasite type.

---

How quickly will cattle improve?

Parasite elimination begins shortly after dosing. Visible improvement depends on parasite load and nutritional status.
