We saw not only a superior and safer delivery system, but an opportunity to minimize risks associated with physical hazards and to give the entire pork chain more peace of mind. PDN needles look and function like standard needles used in modern livestock production. The big differences are the product's proprietary alloy, which has proved to be up to 90 percent more process detectable than stainless steels used today, and the polypropylene hub, which is reinforced to be stronger than typical plastic hubs. PDN needles have proved to be 99.9 percent detectable. Like needles with aluminum hubs, PDN needles bend at the junction of the hub and the needle.
Independent engineers are also impressed with the needle's design.
In this way, the hub and needle stay intact during severe, unrestrained animal movement but enough damage is done that re-use is not an option. While Schering-Plough Animal Health will initially market the needles in North America in conjunction with its growing line of swine vaccines, the company also plans to market them to the U.S. and Canadian cattle industries as well. Schering-Plough Animal Health plans to begin shipping PDN needles in North America by June 2001. They will be available in six sizes ranging from 14 to 20 gauge. While pricing has not yet been announced, the cost in Canada currently averages about CDN 6 cents per hog based on 10 uses per needle, or an equivalent of US 4 cents per hog.
