Three-dose health care for piglets: Inject Dingjian Subizhi 0.25mL at 3 days and 7 days after birth, and 0.5mL at weaning to prevent bacterial infections caused by stress from environment, castration, teeth clipping, tail docking, etc., reduce diseases such as Haemophilus parasuis and Streptococcus, significantly improve survival rate, herd uniformity, and piglet weaning weight. 
One-dose health care for sows after farrowing: Intramuscular injection of Dingjian Subizhi 8~10mL 8~12 hours after farrowing can effectively prevent postpartum syndrome in sows (postpartum mastitis, endometritis, and agalactia). 
Injection combined with oil-based vaccines: Add an appropriate amount of Dingjian Subizhi to pig oil-based vaccines, shake well by hand to mix thoroughly. Combined use can effectively prevent bacterial infections caused by various pathogens, improve prevention efficiency, and reduce prevention costs.

Pharmacological characteristics

Rapid onset, long-lasting effect, high bioavailability, bioequivalent formulation 
After intramuscular injection of ceftiofur sodium, the peak blood concentration is reached in 0.85 hours, the elimination half-life in the body is 11.6 hours, and the drug concentration in the individual remains above the effective concentration for common pathogens after 24 hours, indicating high bioavailability. Data show that intramuscular ceftiofur sodium is rapidly absorbed and slowly released, achieving a perfect combination of rapid and long-lasting effects. It is bioequivalent to imported similar products with consistent clinical effects.

Process advantages

Fine particle size, slow sedimentation, smooth needle passage, mild irritation 
The ceftiofur raw material is ultrafinely pulverized and produced by high-shear colloid milling. The drug particles are small and uniform (molecular particle diameter less than 5μm), sediment slowly (no stratification after 4 hours), have strong needle passage (smooth drawing and pushing with a No. 7 needle), cause no skin irritation, and do not form abscesses. Thixotropic colloid technology is also used to give the suspension excellent suspension stability, good redispersibility, and chemical stability during long-term storage.
