“…Further studies on these subjects would complement our understanding of the importance of wild animal resources to fulfil people's needs, as well as the ecological and social processes that might emerge from the management of fauna in the region. An example of work that evaluates the interactions between introduced domesticates in the TCV and vegetation are the studies that have characterised the plant species consumed by goats [159,160] and those that have assessed the effects of goat herbivory on the growth and flower set of plants [161]. Although goats have been considered detrimental for ecosystems, several authors have documented that, at the right densities, these animals may contribute to the conservation of plant diversity and participate in seed dispersal of numerous species [162][163][164].…”

Background: Interactions between humans and fauna lay in the heart of the history of human subsistence. In Mesoamerica, the Tehuacán-Cuicatlán Valley (TCV) harbours a high biodiversity with archaeological and ethnoecological evidence of its use by people inhabiting the area since at least 12,000 B.P. It is recognized as one of the most ancient areas of agriculture in the Americas, and a broad spectrum of management practices aimed to ensure the availability of desirable plants has been documented, but it has not been analysed for animals. This study aimed to investigate the use and management practices directed to wild animals along current settlements within the TCV and neighbouring areas. Methods: We conducted an extensive search, review and analysis of documental sources for the period between 1967 and 2018. We found 38 documents providing information about the presence of animal species and 15 describing their use and/or management. We included our own observations from four case studies among the Ixcatec, Cuicatec, Nahua and Mestizo people, as well as from regional studies of biodiversity. We used unconstrained multivariate data analysis to describe the management typology of the animals in the region. Results: Hitherto, 652 vertebrate species and 765 species of insects have been recorded in this area; and until present, 107 wild animal species have been reported to be used in 11 use-type categories, mostly for food (65.42%), ornamental (27.52%) and medicinal (21.10%) purposes by the Nahua, Cuicatec, Popolocan, Ixcatec, Mazatec and Mestizo people. Their extraction entails manual capture and gathering as well as hunting and trapping strategies, some of them involving planning in time or space and communitarian regulations; in addition, relocation actions and care in captivity were recorded. Nearly 178 of the species distributed in the region with no reports of local use are used in other localities of Mesoamerica. Ethnozoological information is still lacking for the Mixtec, Chinantec and Chocholtec people in the area. Conclusions: Wild fauna is still a valuable resource for the inhabitants of the TCV. Animals are obtained through extractive practices, which vary from one another in their qualitative attributes. With this work, we provide a context for further research priorities on fauna management in a region of high biocultural significance.

“…A lo largo del año, las variaciones climáticas estacionales acarrean fluctuaciones tanto en la biomasa como en la estructura de la cobertura vegetal y de la relación hoja: tallo. Además, el contenido nutrimental y químico de las plantas también presenta oscilaciones (Foroughbakhch et al, 2013, Mandujano et al, 2019. Todo esto puede influir en el consumo de los animales.…”

Objetivo. Exponer el método de observación visual de categorías de bocados para estimar el consumo de rumiantes en agostaderos, su complejidad, fortalezas y limitantes. Materiales y métodos. La revisión se focalizó en los trabajos que mejoraron el método (validación, aumento en la precisión de la estimación, repetibilidad y fiabilidad) y en la identificación de las fortalezas y limitantes del método, se presentan ejemplos de su uso en etología, nutrición y parasitología. Resultados. El método consiste en un conjunto de técnicas que integran elementos de etología, botánica, nutrición y estadística, resultando en una estimación confiable y detallada de la cantidad y calidad de follaje ingerido por los rumiantes. La validación fue efectuada por diversos autores en estudios que abarcan desde los marcadores de óxido de cromo hasta el uso de animales fistulados. El método de observación de bocados evolucionó a lo largo de los años incorporando mejoras como el refinamiento de las categorías de bocados según el tamaño y forma de las partes de las plantas consumidas (tablas de categorías de bocados), y el uso de protocolos de habituación en los animales a observar para evitar influenciar la conducta de ingestión de los animales bajo estudio. Conclusión. Es un método de bajo costo, respetuoso del bienestar animal, no interfiere con la conducta habitual, la estimación entre observadores tiene buena repetibilidad y exactitud, la estimación es cuantitativa y detallada. Sin embargo, su implementación es laboriosa, requiere conocimientos de etología, botánica y entrenamiento en la identificación de las categorías de bocados. Puede considerarse un método vigente, aplicable si se dispone del recurso humano capacitado.

“…500 g of forage or tree, shrub, and herbaceous pods were collected; the samples were processed for subsequent laboratory analysis. Direct observation method (Arias et al, 2014;Mandujano et al, 2019) was used for forage sampling. An animal was randomly observed for a minute to determine the species being consumed during grazing; the producers provided the names of each species.…”

The Mixteca region of Oaxaca, Mexico, is characterized by extensive grazing of various grasses, shrubs, and trees to raise goats. The objective of this study was to identify and determine the dry matter (DM), organic matter (OM), crude protein, neutral detergent fiber (NDF), and in vitro dry matter digestibility (IVDMD) of the species consumed by goats in the Mixteca region of Oaxaca. The direct observation method was used to collect forage from the species during the rainy (August-September) and dry (April-May) seasons. A botanical collection was made for later identification. The variables considered were the season (rainy, dry) and growth habit (tree, shrub, herbaceous, pod) as treatments. The chemical composition values were analyzed with a completely randomized experimental design. A total of 116 species were identified, of which 74 % were found in the rainy season and 26 % in the dry season. By growth habit, 42 % were trees, 34 % shrubs, and 24 % herbaceous. In addition, 11 % of the total species provided pods that goats consumed. The Fabaceae family was the most represented. Regarding chemical composition, the NDF content of the species was higher (p ≤ 0.05) in the rainy season. By growth habit, the highest values obtained (p ≤ 0.05) for DM were in herbaceous and pods; for OM, in pods; for NDF, in pods and trees; and for IVDMD, in trees, shrubs, and pods. The goat livestock of the Mixteca region in Oaxaca has an important ecological niche. The evaluated species maintain a variable chemical composition between the rainy and dry seasons.
