Three-dose health care for piglets: At 3 days, 7 days, and at weaning, inject Dingjian Sùbìzhì at 0.25 mL, 0.25 mL, and 0.5 mL, respectively, to prevent bacterial infections caused by environmental stressors, castration, tooth clipping, tail docking, and other stressors; reduce the incidence of diseases such as Haemophilus parasuis and Streptococcus; significantly improve survival rates, uniformity of the pig herd, and weaning weights of piglets.
Postpartum health care with a single injection for sows: Administer 8–10 mL of Dingjian Subbi Zhi via intramuscular injection 8–12 hours after farrowing; this can effectively prevent the occurrence of postpartum triad in sows (postpartum mastitis, endometritis, and agalactia).
Combination of oil-based vaccine with injection: Add an appropriate amount of Dingjian Sùbìzhì to the swine oil-based vaccine, shake thoroughly by hand to mix well; when used in combination, it can effectively prevent bacterial infections caused by various pathogenic bacteria, enhance preventive efficacy, and reduce prevention costs.

Pharmacological characteristics

Rapid onset, long duration, high bioavailability, and bioequivalent formulations
Following intramuscular administration of ceftiofur sulfate, peak plasma concentrations are achieved within 0.85 hours, and the drug exhibits a terminal elimination half-life of 11.6 hours. Even after 24 hours, plasma drug levels remain above the minimum inhibitory concentrations for common pathogenic bacteria, demonstrating high bioavailability. Data indicate that intramuscular injection of ceftiofur sulfate is rapidly absorbed yet releases slowly, achieving an optimal balance of rapid onset and prolonged duration of action. Compared with imported products of similar composition, it demonstrates bioequivalence and comparable clinical efficacy.

Process Advantages

Fine particle size, slow settling, smooth needle passage, mild irritation
Cefquinome raw material is subjected to ultramicro‑grinding and processed using a high‑shear colloid mill, yielding a drug with a fine, uniform particle size (particle diameter below 5 μm), slow sedimentation (no layering after 4 hours), excellent needle‑passability (smooth aspiration and injection through a No. 7 needle), non‑irritating to the skin, and no pustule formation. Furthermore, thixotropic colloidal technology is employed, endowing the suspension with outstanding suspending properties, good redispersibility, and long‑term chemical stability during storage.
