In the modern landscape of global livestock management, the demand for efficiency and animal welfare has driven a technological revolution in drug delivery systems. The Twin Syringe for Farm Drug Delivery has emerged as a critical instrument in this evolution. Unlike traditional single-barrel syringes, the twin-delivery mechanism allows for the simultaneous administration of two different vaccines or medications in a single injection site, or separately, without the need for multiple punctures.
The global veterinary syringe market is experiencing a significant shift toward automation and precision. With the rising prevalence of zoonotic diseases and the increasing scale of industrial farming in regions like the Asia-Pacific, North America, and Brazil, farmers are seeking tools that minimize labor costs while maximizing dosage accuracy. The twin syringe technology addresses the "double-handling" problem, reducing animal stress and labor time by up to 50% during mass vaccination campaigns.
The application of twin syringes extends across various livestock sectors:

On May 18–20, 2013, Shaoxing Wanjia participated in the 11th China Animal Husbandry Expo in Wuhan. By 2015, we expanded to major booths in Chongqing, demonstrating our growing operational scale and industry recognition.

Entry into EuroTier Hannover (Germany) marked a milestone. We showcased our Twin Syringe solutions to the European market, gaining insights into advanced farming practices and global biosecurity requirements.

From VIV Asia in Bangkok to IPPE in Atlanta, USA, Shaoxing WANJIA continues to lead. Our participation in AGRAme Dubai and EuroTier 2024 reinforces our position as a top-tier veterinary equipment manufacturer.






When selecting a Twin Syringe for Farm Drug Delivery, several technical parameters must be considered to ensure the longevity of the device and the health of the livestock. Shaoxing WANJIA focuses on these critical engineering aspects:
Our syringes, such as the WJ202 and WJ210-1, utilize TPX (Polymethylpentene) and high-grade plastic steel. These materials are chosen for their exceptional chemical resistance. In a farm environment, syringes are exposed to harsh disinfectants and various oil-based or water-based medications. TPX ensures that the barrel does not cloud or crack over time, maintaining clear visibility for dose measurement.
Mass vaccination of 10,000+ poultry or swine can lead to repetitive strain injuries for farm workers. WANJIA's designs focus on the "A-type" and "D-type" handles, which are balanced to reduce the squeeze force required. This ergonomic focus not only protects the worker but ensures that the last animal receives as precise a dose as the first.
The HRS (High-Resistance System) in our continuous syringes allows for fixed-dose delivery with a tolerance of less than 1%. This is crucial for high-potency drugs where over-dosing is expensive and under-dosing is ineffective. The spiral mouth and Luer-lock connections ensure that needles remain secure even under high pressure during thick medication delivery.
By using durable, autoclavable syringes, farms can significantly reduce plastic waste compared to disposable alternatives. Our products are designed for hundreds of thousands of cycles, aligning with global sustainability goals in the agricultural sector.
