- Product Description
Oxytetracycline Hcl Powder - Veterinary Grade Antibiotic Solution
Xi'an Linnas Biotech Co., Ltd. manufactures pharmaceutical-grade Oxytetracycline Hcl Powder recognized under ISO 9001 quality management systems, with a purity criterion of 99%. For systemic veterinary uses, our product performs much better than base form competitors due to its superior water solubility of about 1g/mL.
Strict pharmacopeial compliance is maintained by the powder, which has assay values between 95.0% and 102.0% (HPLC, anhydrous basis) and a regulated pH of 2.0 to 3.0 in 1% solution. Our formulation guaranties the best stability and safety for managing the health of pigs, poultry, and aquaculture by tightly limiting moisture content below 2.0% and heavy metals under 50 ppm. Samples are available, and shipping is finished three days after payment is confirmed.

Mechanism & Veterinary Applications
By attaching itself to the 30S ribosomal subunit in vulnerable bacteria, our powder acts as a broad-spectrum bacteriostatic agent. Both Gram-positive and Gram-negative organisms, as well as Mycoplasma, Rickettsia, and Chlamydia species, are successfully prevented from synthesizing proteins by this reversible binding.
The powder completely dissolves in automated drinking water systems without clogging in intensive chicken raising. With consistent dosage distribution throughout big flocks, you may depend on it to cure Fowl Cholera, Colibacillosis, and Chronic Respiratory Disease (CRD).
It successfully treats respiratory infections and bacterial enteritis in swine operations. Because of the high tissue permeability, therapeutic doses are delivered to infection sites quickly, lowering mortality rates and increasing feed conversion ratios.
Its stability in medicated feed formulations is advantageous to aquaculture operations. The hydrochloride form remains effective even in the face of difficult water chemistry conditions, whether you are controlling Vibriosis in shrimp farms or Furunculosis in salmon production.
Manufacturing Excellence & Quality Assurance
Automated manufacturing lines with real-time monitoring systems are used in our production facility. Each batch is subjected to a thorough High-Performance Liquid Chromatography (HPLC) analysis to confirm potency and identify contaminants such as tetracycline and 4-Epioxytetracycline.
Tests for light-absorbing impurities verify photo-stability during transportation and storage. Because Oxytetracycline Hcl Powder is hygroscopic and needs to be handled carefully to retain its crystalline structure, we maintain stringent environmental controls to prevent moisture exposure.
Low bioburden is ensured by microbial limit testing, which confirms the absence of E. Coli and Salmonella. Feed safety compliance in international markets is ensured by residue on ignition remaining substantially below regulatory levels.
USP, EP, and BP pharmacopeial requirements are met by our quality control procedures. When importing to North America, Europe, or Asia-Pacific, this triple compliance streamlines your regulatory paperwork.
Storage & Handling Recommendations
Keep the powder out of direct sunlight and moisture by storing it in well sealed containers. In low-humidity settings, the ideal storage temperature is between 15 and 25°C to avoid deterioration.
Because of the product's susceptibility to alkaline environments, basic chemicals should be avoided during formulation. For optimal stability, use neutral or slightly acidic water sources when making water-soluble solutions.
Use first-in, first-out inventory rotation for large-scale operations. Fresher batches retain maximum potency for crucial medicinal uses, even tho shelf life can reach 24 months under the right circumstances.
Wear the proper personal protective equipment, such as gloves and dust masks. During transfer operations, the tiny crystalline powder may become airborne, necessitating sufficient ventilation in processing areas.

Frequently Asked Questions
Q: What distinguishes the hydrochloride form from the base of oxytetracycline?
A: The HCL form provides far more water solubility (about 1g/mL compared to the base's restricted solubility), allowing for faster absorption in non-ruminant animals and efficient mass medicine thru drinking water systems.
Q: Is it possible to utilize this product in organic farming operations?
A: Although our production satisfies organic facility requirements, most countries limit the use of antibiotics in certified organic animals. Before applying, check with your organic certifying body.
Q: How do you make sure that every batch has the same potency?
A: HPLC analysis is performed on each production batch to verify 99% minimum assay values. To ensure pharmaceutical-grade uniformity throughout the manufacturing process, we employ stringent environmental controls and raw material screening.
Q: How long does it usually take for animals that have received treatment to withdraw?
A: Depending on the species and local laws, withdrawal times differ. Before being killed, poultry typically need 5–7 days, pigs 14–21 days, and aquaculture species 21–30 days. Always refer to the veterinary authorities in your area.
Q: Do shipments come with a Certificate of Analysis?
A: A thorough COA including all quality criteria, such as HPLC assay, moisture content, heavy metals, and microbiological limits, is included with every shipment.
