A study was conducted to determine the adaptive response to high salt diets of feral hogs living in the salt marshes of Ossabaw Island, Georgia. Two groups of hogs were used. One group consisted of three feral hogs from Ossabaw Island and the other of three domestic Hampshire hogs. Both groups were maintained in metabolism cages under constant environmental conditions and fed consecutive diets of 0.5%, 3%, and 6% salt (NaCl) content. During each dietary regime, observations were made on food… 

Renal structural flexibility in response to environmental water stress in feral hogs.

Since the feral hogs living in the wild were exposed to a higher degree of water stress than the captive-raised hogs, it was concluded that the differences in observed kidney structure were due to acclimatization.

Plasma electrolyte concentrations in captive and free-ranging African penguins (Spheniscus demersus) maintained with and without dietary salt supplements

Experimental evidence is provided that African penguins maintained in freshwater exhibits on a herring-, capelin-, and squid-based diet do not require salt supplementation, providing evidence that penguins do not need to ingest high salt concentrations to remain in electrolyte balance.

Enhancing pork flavor and fat quality with swine raised in sylvan systems: Potential niche-market application for the Ossabaw hog

Forest-finished Ossabaw pork was considered more flavorful by food critics and renowned chefs than that of conventionally fed animals, and Mast from hardwoods offers the possibility of enhancing pork flavor for niche markets and using a renewable forest resource as a food source.

Renal Morphology of Sympatric Suiforms: Implications for Competition

Results were consistent with predictions that peccaries should have a competitive advantage over hogs in xeric environments with minimal surface water because of ecophysiology, however, a suite of environmental, behavioral, and functional factors appears to control competitive interactions between native peccary and introduced hogs.

The effective regulation of energy and water budgets during water restriction suggests that the fruit bat can cope with seasonal climatic changes and with variable fruit supply during various seasons.

The existence of problems with wild pigs (Sus scrofa) is nothing new to the Western Hemisphere. Damage by these introduced animals was reported as far back as 1505 by the early Spanish colonies in

Ossabaw Island miniature swine: Cardiometabolic syndrome assessment

Ossabaw miniature swine may recapitulate the natural pathogenesis of type 2 diabetes because of their “thrifty genotype” that enabled survival in the feast and famine ecology of Ossabaw Island.

The role of landscape composition and disturbance type in mediating salt marsh resilience to feral hog invasion

Novel evidence is provided that habitat patch composition at landscape scales can act together with local habitat attributes to dictate invasive species’ disturbance patterns and highlight areas most vulnerable to invaders in salt marshes.

Water requirements of African goats and haired-sheep

It would appear that African goats and haired-sheep lack the physiological mechanisms and are not free to utilize the behavioural mechanisms involved in freeing wild desert-dwelling ungulates from their dependence on drinking water.

Water metabolism of Merino and Border Leicester sheep grazing saltbush.

During late summer, Border Leicester wethers running with Merinos on a pure Atriplex nummularia stand turned over more water than Merinos but only about half as much water was required as on saltbush, suggesting differences in functional types of adjustment to saltbush associations.
