Accuracy and precision of Pulse Micro-dose Injection Device using Draxxin, Excede, Excenel and sterile water

摘要

The use of traditional syringes with needles for treating pigs can pose a safety hazard to the animal and the food supply. Needles can cause damage to carcasses at the injection site,1'2> 4 be a hazard if they break while injecting5, and can act as afomite to spread disease.3 These risks represent not only a pork safety concern, but they also have a significant economic impact on the pork industry. Abscesses and injection-site lesions alone cost the industry almost 1.5 million dollar in 1994, according to the Pork Chain Quality Audit.2 Needle-free injection devices address some of these issues. When using a needle-free injection device, it is important to know if the desired amount of product is truly being injected into the animal and if it will be repeatedly accurate. For producers to feel confident in a needle-free injection device, the accuracy and precision should be determined for the range of compounds that may be used.
