Los ovinos Pantaneiro tienen unas características peculiares, son animales de lana, pero no tienen lana en el vientre y miembros inferiores, son sexualmente precoces y no presentan estacionalidad reproductiva, producen canales de alto rendimiento, tienen piel de características intermedias, entre los ovinos de pelo y los ovinos de lana. Están muy adaptados a las condiciones del Bioma Pantanal, ya que su formación genética es elresultado de siglos de selección natural desde la llegada del primer ovino con los colonizadores. Este artículo reúne informaciones de investigaciones realizadas en los últimos quince años con este recurso genético. Se evaluaron medidas morfométricas y estandarización de la raza, teniendo en cuenta el origen genético, color, cabeza, orejas,cuello, tronco, piel, ubre, extremidades, vellón, cola y testículos, seguido de índices zootécnicos y las características productivas de la carne, la leche, lana y piel, destacando el grupo genético Pantaneiro como polivalente. La raza ovina Pantaneira es una opción genética para los ganaderos, porque tiene potencial productivo posible su explotación económica.

Qualitative Characters of Indigenous Sheep in Central Brazil: Putting Phenotype into Perspective

et al. 2021

For centuries, indigenous sheep have been bred in extensive low-input systems in Midwestern Brazil. The hypothesis of this study was the assumption that phenotypic evaluation of indigenous livestock may drive the establishment of breed standards and official breed recognition, and, therefore, promote more local business opportunities. On the basis of more integrative and participatory theoretical background to applying any decision based on phenotype, we designed this research to determine the most typical and unusual phenotypes of Pantaneiro sheep. Pantaneiro ewes (281 ewes from five conservation units in five counties) were evaluated, bearing in mind both conservation and development. Descriptive statistics were used to classify ewes into typical, intermediate, and unusual phenotypes. Chi-squared tests for association were performed to test if morphological variation in the different sampling sites occurred randomly (p > 0.05) or not (p < 0.05). Some results suggest some sort of diversifying selection pressure, i.e., distinct preferences among keepers. We observed considerable morphologic variation among ewes, but it was straightforward to determine the predominant phenotypes. The study evokes integrative agrobiodiversity by putting phenotypical characterization of indigenous livestock into perspective. Discussions coming from this study may support innovative governance and participative decision-making, allied with strategies that value the socioeconomic, biocultural, and adaptive aspects of indigenous livestock in tropical regions and developing countries. This is a challenge for government, rare-breed keepers, value-chain actors, and civil society.

“…An analysis of morphometric characterization, using 338 naturalized sheep from Mato Grosso do Sul and performed 20 morphometric measurements, concluded that the females of this genetic group have relatively large heads (32.4 cm), and this feature along with the length of the skull (24.2 cm) are larger in females than in males [23].…”

Brazil has several breeds of sheep, including animals that developed from breeds brought by settlers soon after their discovery. Over the years, these animals were under the process of natural selection, resulting in breeds that are considered naturalized. The Pantaneiro sheep shows rusticity and ability of adaptation to tropical climate regions and tolerance or resistance to disease and parasites. Molecular tools have marked the discovery of the origin and domestication processes of a wide variety of species, using both nuclear and mitochondrial molecular markers. These tools have aided in the understanding of evolutionary relationships, taxonomies, and demographics of various species and provided support to identify the most important areas for conservation programs, in addition to assisting in the analysis of genetic diversity in domestic, wildlife and endangered species. Researches using these tools show the importance of exploiting the potential of the genetic diversity found in locally adapted livestock. So far, a few studies were performed to observe that Pantaneiro sheep served as maternal basis for the origin of other breeds reared. Moreover, it is possible to suggest an European origin for the sheep populations studied; therefore, more studies using more markers are needed, so that it is possible to prove their origin.
