We examined feral pig tissues to determine whether the potential hazard of consuming meat from pigs previously exposed to diphacinone rodenticide baits was reduced by cooking. Residue levels were measured in cooked and uncooked tissues of feral pigs exposed to sub-lethal quantities of the anticoagulant rodenticide. Pigs were provided large amounts of baits or untreated food to consume, then euthanized prior to the onset of symptoms indicative of rodenticide poisoning or sickness. For analysis, we grouped pigs into three levels of mean diphacinone consumption: 0, 3.5, and 7.4 mg/kg. None of the pigs displayed obvious signs of toxicity during the …

Developing organisms must reconcile conflicts between demands of survival within the current life-history stage, with those of maturation, while negotiating the transitions through succeeding stages. In the case of feeding performance, the parts of the feeding apparatus and their biomechanics must maintain functional integrity to meet the feeding needs of a juvenile even as they develop toward their adult form. We concurrently examine the ontogenetic relationships of feeding performance, dentition and feeding biomechanics, relative to key life-history events, utilizing samples drawn from the same population of known-age coyotes Canis latrans. The development of feeding performance is asynchronous with development …
