Indigenous sheep breeds in Brazil: potential role for contributing to the sustainability of production systems

Abstract

Brazil has vocation for food production, both vegetable and animal, with the sheep industry having an expanding activity. However, productivity rates are often bellowing the possibilities of the country. Here, the roles the native breeds may develop in this expanding activity are described. Breeds considered are the hair breeds Santa Inês, Morada Nova, Somális Brasileira, Cariri, and Rabo Largo, and the wool breeds Bergamácia Brasileira, Crioula Lanada, and Pantaneira. These breeds have arisen in environments that may be considered difficult for other (exotic) breeds, less adapted to the local conditions. The hair breeds emerged in a semi-arid environment, a hot and with low rainfall region, of the Northeast of Brazil. The Crioula Lanada is the only breed that originated in the South, in a subtropical region with cold winters. The genetic group Pantaneira had its origin in an environment with higher humidity, especially soil moisture. The Bergamácia Brasileira derived from the Italian Bergamasca breed, which was first introduced in northeastern Brazil. Animals from these breeds have been regarded as robust, with lower requirements for maintenance, resistant to worms, and easy to handle. On the other side, as they are generally smaller than the exotic breeds used for meat production, they are often considered as less productive. In this literature review, a possibility of valorizing them, both as purebred or in crossbreeding programs, especially for meat production is addressed. These breeds are part of the genetic, historical, and cultural heritage of Brazil, and if used properly, according to the different environments and production systems, they can also be very important in the development of the sheep industry.

Use of multivariate analysis as a tool in the morphological characterization of the main indigenous bovine ecotypes in northeastern Algeria

“…In order to deal with the effects of globalization, urbanization, mechanization, increase in world population, global warming and climate change, it is urgently needed to transform our agriculture and livestock farming systems to more sustainable agriculture by taking into account the environmental considerations (fight against climate change, genetic characterization and monitoring of local breeds which are well adapted to the local environment, preserving and redeploying biodiversity endangered breeds) [1,2]. Moreover, this transformation aims also to provide a fair and stable income and good working conditions to farmers and could contribute significantly to social equity and local economies [3][4][5].…”

Short-, Medium- and Long-Term Metabolic Responses of Adult Meat Ewes Subjected to Nutritional and β-Adrenergic Challenges

“…The efficiency of BR mobilization-accretion processes, to overcome undernutrition, is therefore recognized as an essential mechanism in ruminants [ 3 , 4 , 5 , 6 ]. These processes contribute to maintaining the resilience of the flock under a fluctuating feed supply, such as in tropical [ 7 ] or Mediterranean regions, where seasonal forage availability is highly fluctuating.…”

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

“…Typically, Pantaneira sheep, named after the Pantanal ecosystem (a biodiversity hotspot in Midwestern Brazil), are kept in low-input grazing systems [10]. Currently, the sheep breeders' association in Brazil lacks an official description of Pantaneiro sheep [11].…”
