EXCEDE is a powerful, long-acting antibiotic used primarily in veterinary medicine to treat various bacterial infections in livestock. As a member of the cephalosporin class of drugs, it is specifically formulated as ceftiofur crystalline free acid, which allows for a sustained release of medication over several days. This unique delivery method makes it a preferred choice for veterinarians and producers who need effective treatment with minimal animal handling.
In this guide, you will learn about the specific applications of EXCEDE for cattle, swine, and horses. We will cover the benefits of using a long-acting antibiotic, the proper administration techniques, and the safety precautions necessary to ensure animal health and food safety. Whether you are a livestock owner or simply curious about veterinary treatments, this article provides a clear overview of what makes EXCEDE a vital tool in animal husbandry.
What is EXCEDE Antibiotic?
EXCEDE is a prescription antibiotic approved by the FDA for use in specific animal species. It is not intended for human use. The active ingredient, ceftiofur, is a broad-spectrum antibiotic that is effective against both Gram-positive and Gram-negative bacteria.
The “crystalline free acid” formulation is what sets EXCEDE apart from other antibiotics. When injected, the medication creates a depot at the injection site that slowly releases the drug into the animal’s bloodstream. This allows a single dose to maintain therapeutic levels for an extended period, often up to seven to ten days depending on the species and the condition being treated.
By providing a full course of therapy in a single injection, EXCEDE reduces the labor required for treatment. It also minimizes the stress on the animal, as they do not need to be caught or restrained for daily dosing. This efficiency is particularly valuable in large-scale agricultural operations and for animals that are difficult to handle.
Common Uses for Cattle
In the beef and dairy industries, EXCEDE is most commonly used to combat Bovine Respiratory Disease (BRD), also known as shipping fever. BRD is a complex infection that can be caused by various bacteria, including Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni.
Beyond respiratory issues, EXCEDE is also indicated for the treatment of other common cattle ailments:
- Bovine Foot Rot: This is an acute infection of the interdigital tissues. EXCEDE helps clear the bacterial infection, reducing lameness and swelling in the hoof area.
- Acute Metritis: This is a bacterial infection of the uterus that typically occurs within 10 to 14 days after calving. EXCEDE is effective against the pathogens associated with this condition, helping the cow recover quickly.
Because cattle are often part of the food supply, using EXCEDE requires strict adherence to withdrawal periods. These periods ensure that no drug residues remain in the meat or milk when the animal eventually goes to market.
Usage in Swine and Horses
While cattle are the primary users of EXCEDE, the antibiotic is also highly effective for swine and horses. In swine, it is primarily used to treat Swine Respiratory Disease (SRD). This condition is often associated with Actinobacillus pleuropneumoniae and Streptococcus suis, both of which are sensitive to ceftiofur.
For horses, EXCEDE is used to treat lower respiratory tract infections. These infections are frequently caused by Streptococcus equi ssp. zooepidemicus. Because horses can be sensitive to various medications, the long-acting nature of EXCEDE is beneficial as it reduces the frequency of injections needed to resolve the infection.
It is important to note that the administration site and dosage for horses and swine differ significantly from cattle. Always follow the specific label instructions or your veterinarian’s guidance for each specific animal type.
Key Benefits of EXCEDE
The primary advantage of EXCEDE is its convenience and efficacy. Traditional antibiotics may require daily injections for three to five days to be effective. In contrast, EXCEDE provides a complete course of therapy in one dose.
Reduced Animal Stress: Every time an animal is handled for medical treatment, it experiences stress. Reducing the number of injections to one significantly improves animal welfare and reduces the risk of injury to both the animal and the handler.
Improved Compliance: In veterinary medicine, “compliance” refers to completing the full course of antibiotics. With daily injections, it is easy to miss a dose or stop treatment early once the animal looks better. EXCEDE ensures the animal receives the full therapeutic dose every time.
Broad-Spectrum Coverage: Because it targets a wide variety of bacteria, it is a versatile tool for veterinarians. It can be used as a first-line treatment for many common infections without waiting for lengthy lab results in many cases.
How to Administer EXCEDE Correctly
Proper administration of EXCEDE is critical for the drug to work correctly and to avoid complications. The injection site varies by species, and using the wrong site can lead to ineffective treatment or tissue damage.
Administration in Cattle
For cattle, EXCEDE is uniquely administered via a subcutaneous injection at the base of the ear. This specific location is used because it allows for the slow release of the medication without affecting the quality of the meat in the primary carcass cuts. It is vital to avoid injecting into the ear canal or the blood vessels of the ear.
Administration in Swine
In swine, the injection is typically given intramuscularly in the post-auricular region (the neck area just behind the ear). The dose is calculated based on the weight of the pig, and it is important not to exceed the recommended volume per injection site.
Administration in Horses
For horses, EXCEDE is administered as two intramuscular injections, usually given four days apart. The injections are typically placed in the large muscles of the neck. It is recommended to rotate the injection site between the left and right sides of the neck to minimize soreness.
Storage and Handling Requirements
To maintain the potency of EXCEDE, it must be stored correctly. The medication should be kept at controlled room temperature, typically between 68°F and 77°F (20°C to 25°C). It should be protected from light and should not be allowed to freeze.
Once the vial has been punctured, the contents must be used within a specific timeframe, usually 12 weeks, as long as it is stored properly. Always check the expiration date on the bottle before use. If the suspension appears discolored or contains unusual particles, it should be discarded.
Before drawing the medication into a syringe, the vial must be shaken vigorously. Because it is a “crystalline” suspension, the active ingredients can settle at the bottom. Thorough shaking ensures the animal receives the correct concentration of the drug.
Safety Precautions and Side Effects
While EXCEDE is safe for livestock when used as directed, there are several precautions to keep in mind. First, this drug should never be used in animals that have a known hypersensitivity to cephalosporins or beta-lactam antibiotics. Allergic reactions, though rare in livestock, can occur and may require immediate veterinary attention.
Common side effects at the injection site include:
- Swelling: Temporary localized swelling is common, especially in horses and cattle.
- Soreness: The animal may show signs of tenderness at the injection site for a few days.
- Tissue Discoloration: In cattle, there may be some discoloration at the base of the ear, which is why the ear is the preferred site to protect the value of the carcass.
One of the most important safety factors is the withdrawal period. For cattle intended for slaughter, there is a specific number of days that must pass after the last injection before the animal can be processed for meat. Similarly, while EXCEDE has a zero-day milk discard period for dairy cattle when used according to the label, using it off-label can change these requirements. Always consult your veterinarian regarding withdrawal times.
Conclusion
EXCEDE is a highly effective, long-acting antibiotic that has revolutionized the way bacterial infections are managed in livestock. By providing a full course of treatment in a single dose, it offers a practical solution that balances animal welfare with agricultural efficiency. Understanding the proper use, administration, and safety protocols for EXCEDE ensures that animals stay healthy and the food supply remains safe.
If you suspect your livestock is ill, the first step should always be to consult with a licensed veterinarian. They can provide an accurate diagnosis and determine if EXCEDE is the right treatment for your specific situation.
