New vaccine features a needle-free delivery system.

Merial has introduced the first and only USDA-approved swine respiratory vaccine administered by a needle-free delivery system. SWIVAX-MH was approved to aid in the reduction and control of Mycoplasmal pneumonia, and has been specifically formulated to be administered exclusively with the DERMA-VAC NF Transdermal Vaccination System, also new from Merial. SWIVAX-MH is prepared from inactivated cultures of mycoplasma combined with an adjuvant. The vaccine cannot be administered with a conventional needle and syringe. The needle-free system works to deliver vaccine by release of a small amount of pressurized gas upon triggering, which forces the vaccine through the nozzle orifice of the delivery system. An ultra-fine stream of vaccine, moving at high initial pressure and speed, penetrates the skin and is dispersed into the animal tissue. There are many advantages to using transdermal delivery. “This mode of administration will allow for a targeted immune response, reduction of broken needles and increased worker safety,” explains Frank Milward, Merial Biological Research and Development. “Also, less product is required for vaccination — 0.5 ml vs. a typical dosage of 1.0 ml to 2.0 ml.” For more information, contact your local Merial sales representative or call (888) 637-4251.

Reproductive Data Management

Iowa Pork Industry Center (IPIC) of Iowa State University has developed Sow Tracker, their new swine reproductive data management software. This entry-level software is designed to assist the swine producer in managing the breeding, farrowing and weaning aspects of a swine production enterprise. Written in MS-Access and compatible with USB printers, Sow Tracker is comprised of more than 14 reproductive data management reports to assist the producer in his farrowing operation. Data entry is simplified using a drop-down, menu-based system. It's easy to modify sow numbers in full view of the sows' full reproductive history. All basic events such as entry, mating, pregnancy check, group identification, location identification, farrow, foster, pig death, wean, part wean, nurse on, nurse off and sow removal are included. Data can be extracted for upgrading to more comprehensive software applications. For more information, contact IPIC Director John Mabry at (515) 294-4103 or
