Knowledge on the nutritional and sensory characteristics of wild meat provides a better basis for its use as food, ultimately expanding studies in gastronomy areas and stimulating the development of new products. This review aims to present information on the use of wild meat, with a focus on collared peccaries (Pecari tajacu). The biological characteristics of collared peccaries are discussed, with a focus on the main aspects of their meat. Collared peccary meat has excellent nutritional value due to its high protein levels (18.25%), unsaturated fatty acids (51.6-57.8%), and tenderness, similar to other domestic animals, thereby stimulating the interest of a new product market. Despite the demand for this product, collared peccary meat is scarce and not readily available for commercialization. Further, public policies are needed to encourage the management of this species to add value to the development of a production chain.
The collared peccary ( Linnaeus, 1758) is a vital resource for the subsistence and economy of the Amazonian inhabitants. Despite its importance, there is a notable lack of genetic information on Peruvian collared peccary populations. This study presents the complete mitogenome of from Peru, obtained by Illumina sequencing.
- Mineral licks in the Amazon are crucial for large mammals, serving as key resources that affect their behavior and ecological interactions, particularly in the Peruvian Amazon.
- The study monitored six large mammals using camera traps and soil analyses, finding that mineral licks provide vital nutrients like sodium, especially for frugivorous species, while also playing a role in toxin mitigation for others like the Brazilian porcupine.
- The research emphasizes the necessity of protecting mineral lick sites, highlighting their contribution to biodiversity and the overall health of the Amazonian ecosystem.
Parasitic infections of the gastrointestinal tract of domestic animals play a major role in the transmission of disease, which in turn may result in financial and productive losses. Notwithstanding, studies on the burden and distribution of diarrheagenic protists in zoological gardens are still insufficient. Given the close animal-animal and animal-human interaction in these settings, Public Health concerns under the One Health context are raised.
This work aims to study the major salivary gland morphology of peccaries during their growth. The glands were analyzed using macroscopic description, light microscopy, electron microscopy, histochemistry, and immunohistochemistry. Topographically, the salivary glands resemble other animals, including domestic animals and pigs.
The study examines how predator hunting strategies (stalking by cougars and coursing by wolves) affect the movement behaviors of both predators and their ungulate prey in eastern Washington.
Using hidden Markov models on data from over 400 GPS-collared animals, researchers found that while predators adjusted their movements based on prey type, ungulates reduced their movement in areas with large predators, regardless of the predator's strategy.
The results indicate that predator and prey movements are influenced more by long-term patterns of risk and resource distribution than by specific hunting behaviors, highlighting the complexity of interactions in multi-predator, multi-prey systems.
