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

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, promot...
