“…One such tool that has received increased interest is the use of baits as delivery vehicles for pharmaceuticals, such as oral vaccines, to feral swine (Fletcher et al, 1990). The foundational basis for this technology stems from .35 yr developing and implementing oral vaccination programs in Europe (Schneider et al, 1988), New Zealand (Barlow, 1991), and the United States (Baer et al, 1971) in other mammalian species.…”

“…In the United States, investigations involving feral swine oral delivery systems (or baits) have been limited to three studies; two of these studies were conducted on Ossabaw Island, Georgia (Fletcher et al, 1990;Kavanaugh and Linhart, 2000), and one study was conducted in southern Texas . These studies found high removal, high consumption rates, or both of baits made up of or flavored with fish or corn products by feral swine and nontarget animals, such as raccoons (Procyon lotor).…”

ABSTRACT:Within the domestic swine industry there is growing trepidation about the role feral swine (Sus scrofa) play in the maintenance and transmission of important swine diseases. Innovative disease management tools for feral swine are needed. We used field trials conducted in southern Texas from February to March 2006 to compare species-specific visitation and removal rates of fish-flavored and vegetable-flavored baits with and without commercially available raccoon (Procyon lotor) repellent (trial 1) and removal rates of baits deployed in a systematic and cluster arrangement (trial 2). During trial 1, 1) cumulative bait removal rates after four nights ranged from 93% to 98%; 2) bait removal rates by feral swine, raccoons, and collared peccaries (Pecari tajacu) did not differ by treatment; and 3) coyotes (Canis latrans) removed more fish-flavored baits without raccoon repellent and white-tailed deer removed more vegetable-flavored baits without raccoon repellent than expected. During trial 2, feral swine removed fish-flavored baits distributed in a cluster arrangement (eight baits within 5 m 2 ) at a rate greater than expected. Our observed bait removal rates illustrate bait attractiveness to feral swine. However, the diverse assemblage of omnivores in the United States compared with Australia where the baits were manufactured adds complexity to the development of a feral swine-specific baiting system for pharmaceutical delivery.

“…PIGOUT ® Feral Pig Baits (Prototype 2) (Animal Control Technologies, Somerton, Victoria, Australia) were spiked with IA by drilling a 0.6 cm hole into the center of the bait. The marker was injected at 22.7 mg/bait, a quantity known to mark feral pig serum [17]. On day 1, 1170 IA marked baits were placed on the property on transects (n = 18) oriented on a 273 • azimuth and spaced at 260 m intervals.…”

“…In the past, IA has been successfully used as a marker in bait acceptance studies in a variety of animal species including carnivores [6][7][8][9][10][11], herbivores [12][13][14][15][16] and omnivores [17] and has been used to determine the feasibility of delivering oral vaccine to wild swine [17] and raccoons [9,24]. Field experiments in which feral pigs (S. scrofa), raccoons (P. lotor), and opossums (D. virginiana) were exposed to IA following ingestion of IA-marked baits were used to confirm the appropriateness of (−)ESI/LC-MS identification in these studies.…”

Liquid chromatography-electrospray ionization mass spectrometry for direct identification and quantification of iophenoxic acid in serum" (2006 AbstractA liquid chromatographic-electrospray ionization mass spectrometric technique was developed for direct quantitation of iophenoxic acid (IA) in serum. IA was spiked into canine, feline, bovine, equine, and porcine sera, extracted, and quantified using negative ion monitoring following chromatographic separation on a Luna C18(2) 3 m (100 mm × 2.1 mm) reversed-phase column. The limit of detection was 25 ng/mL and the limit of quantification was 50 ng/mL. Inter-and intra-assay accuracy (86-113% and 87-115%, respectively) and precision (1.8-7.7%) were calculated. Analysis of serum collected from feral pigs, raccoons, and opossums following ingestion of IA-marked baits confirmed the appropriateness of this method for bait acceptance studies.

Daily and Landscape Influences of Species Visitation to Toxic Bait Sites for Wild Pigs

Toxic baiting of wild pigs (Sus scrofa) is a potential new tool for population control and damage reduction in the United States. Use of toxic bait sites by non‐target species is concerning because of the risks posed from exposure to a toxic bait. A 2018 field trial in northern Texas, USA, examining the efficacy of a prototype toxic bait (HOGGONE®, containing 10% sodium nitrite) revealed unexpected hazards to non‐target species, primarily passerine birds, from consuming toxic bait spilled outside of bait stations by wild pigs. The hazards jeopardize the ability to register HOGGONE as a tool for controlling wild pigs. We conducted a post hoc analysis from that 2018 trial to identify how daily and landscape factors influenced the use of bait sites by non‐target species, and subsequent hazards from consuming the toxic bait. We discovered that no single strategy can eliminate visitations by all non‐target species, but offering the toxic bait at night, in wild‐pig specific bait stations, and in more homogeneous landscapes appeared to be the best strategy for minimizing visits by passerine birds. We also found that use of bait sites by wild pigs were temporally clustered, and more pigs visited bait sites along linear features of the landscape (e.g., agricultural edges or riparian corridors). We recommend a baiting strategy where applicators do not place bait stations directly at sites where remnant particles of grain (from prebaiting) are available on the ground. Published 2021.
