United States Department of Agriculture Wildlife Services: Staff Publications

Habitat fragmentation and degradation have led to a proliferation of small and isolated populations that are vulnerable to genetic erosion. Reduction in habitat and concomitant declines in population connectivity can expediate the collapse of species that exist as natural metapopulations. In recent years, Allegheny woodrats (Neotoma magister) have experienced local extirpations and declines in genetic diversity across their range due to disease-related mortality, reduced food availability, and disruption of connectivity among subpopulations. In response, we developed a captive-breeding program to facilitate genetic management of isolated woodrat populations in Indiana. Between 2010 and 2012, 27 captive-reared individuals were released to four …

Economic Estimates Of Wild Hog (Sus Scrofa) Damage And Control Among Young Forest Plantations In Alabama, Micah Fern, Rebecca Barlow, Chris Slootmaker, John Kush, Stephanie Shwiff, Larry Teeter, Jim Armstrong

United States Department of Agriculture Wildlife Services: Staff Publications

Operating as ecological engineers, the increased distribution and abundance of wild hogs (Sus scrofa) has caused considerable socio-economic impacts. The international scope of economic research providing wild hog damage estimates are often confined to agricultural crops, while damage estimates among forest plantations are lacking. In Alabama, private landowners hold the majority of timberland acreage and are less equipped to absorb financial losses from wild hog damage than their industrial counterparts. A survey was conducted to estimate the economic impact of wild hogs, namely costs of damage and control, to privately owned forestlands. The survey was distributed in the …

United States Department of Agriculture Wildlife Services: Staff Publications

Toxic baiting of wild pigs (Sus scrofa) is a potential new tool for population control and damage reduction in the US. Field trials testing a prototype toxic bait (HOGGONE 2 containing 5% sodium nitrite [SN]), though, revealed that wild pigs spilled small particles of toxic bait outside of bait stations which subsequently created hazards for non-target species that consumed those particles, primarily passerine birds. To deter non-target birds from consuming particles of spilled bait, we tested four deterrents at mock bait sites (i.e., baited with bird seed) in north-central Colorado, USA during April–May 2020. We found a programable, inflatable deterrent …

United States Department of Agriculture Wildlife Services: Staff Publications

A challenge that conservation practitioners face is manipulating behavior of nuisance species. The turkey vulture (Cathartes aura) can cause substantial damage to aircraft if struck. The goal of this study was to assess vulture responses to unmanned aircraft systems (UAS) for use as a possible dispersal tool. Our treatments included three platforms (fixed-wing, multirotor, and a predator-like ornithopter [powered by flapping flight]) and two approach types (30 m overhead or targeted towards a vulture) in an operational context. We evaluated perceived risk as probability of reaction, reaction time, flight-initiation distance (FID), vulture remaining index, and latency to return. …

Management Strategies For Improving Survival Of Piglets From Hyperprolific Sows, R.N. Kirkwood, P. Langendijk, J. Carr

The Thai Journal of Veterinary Medicine

In efforts to improve profitability, sows have been subject to ongoing selection for larger litters. The current dogma is that larger litters improve sow productivity. This review, however, will question the validity of this assumption. It is inescapable that very large litters will have longer farrowing durations, lower average and more variable birth weights, and the sows will have insufficient teats available to feed their piglets. This is a recipe for increased piglet mortality with associated ethical considerations. This review will examine methods employed to address these challenges posed by larger litters in order to improve piglet survival. Producers, however, …

United States Department of Agriculture Wildlife Services: Staff Publications

Anthrax is a disease of concern in many mammals, including humans. Management primarily consists of prevention through vaccination and tracking clinical-level observations because environmental isolation is laborious and bacterial distribution across large geographic areas diffi cult to confi rm. Feral swine (Sus scrofa) are an invasive species with an extensive range in the southern United States that rarely succumbs to anthrax. We present evidence that feral swine might serve as biosentinels based on comparative seroprevalence in swine from historically defi ned anthrax-endemic and non–anthraxendemic regions of Texas. Overall seropositivity was 43.7% (n = 478), and logistic regression revealed county endemicity …

The Alterations Of Fecal Microbiota In Dogs With Acute Diarrhea, Thailand, Jeerawat Soonthornsit, Natharin Ngamwongsatit, Panpanga Sangsuriya, Nlin Arya

The Thai Journal of Veterinary Medicine

Acute diarrhea is a common clinical sign in dogs which the pathogenesis has associated with altered gut microbiome compositions and influenced by diet, environment, and medication. However, the impact of gut microbiome on dog health has still not been well elucidated in Thailand. This study aims to investigate the alterations of the fecal microbiome in dogs with diarrhea (<3 days) compared to healthy dogs. Fresh feces were collected once from each dog, and DNA extraction was performed following the QIAamp DNA stool mini kit protocol. The 16s rRNA gene, then, amplified and analyzed by the next-generation DNA sequencing technology. The results showed a significant reduction of the evenness and Shannon index in dogs with the diarrhea group. The most dominant phylum in healthy dogs, Firmicutes, was markedly declined. Additionally, significant decreases in bacterial abundances were observed in twelve genera. To the best of our knowledge, seven of them were first described in their alterations including Clostridium sensu stricto 1, Lachnospiraceae NKA4136 group, Erysipelatoclostridium, Tyzzerella 3, Alloprevotella and Slackia. Therefore, these findings disclose the new possible biomarkers for intestinal diseases and the effect of ordinary diets on the fecal microbiome in dog health, Thailand.
