Loncor 300 (Florfenicol) Injectable Solution for Cattle

Loncor 300 (Florfenicol) Injectable Solution

Bovine respiratory disease (BRD) presents a significant challenge for cattle farmers, leading to decreased productivity, increased veterinary costs, and potential losses. Loncor 300 Florfenicol Injectable Solution is a powerful antibiotic specifically formulated to treat BRD, providing effective and long-lasting relief from bacterial infections. 

Unlike many antibiotics that require frequent dosing, Loncor 300 offers a convenient, single-dose administration, minimizing stress on cattle and reducing labor costs. Its broad-spectrum activity ensures that it targets the most common bacteria responsible for respiratory diseases in cattle, delivering rapid and reliable results.

Moreover, with careful storage and precise administration, Loncor 300 maintains its potency and efficacy, making it an essential tool for cattle health management.

Prescription items are NON-RETURNABLE and NON-REFUNDABLE.
