“…Gochu Asturcelta individuals are rustic-prolific pigs with slow growth but are well adapted to specific local environments and to using locally available feedstuffs. The characterization of carcass yields and meat quality while keeping traditional extensive or semi-extensive rearing systems is initiated only [22,23]. After the foundation of the breeding program, a strict mating policy was implemented aiming at keeping founder contributions balanced across generations by prolonging the reproductive career of the founders and their direct descendants for as long as possible [17].…”

Copy number variations regions (CNVRs) can be classified either as segregating, when found in both parents, and offspring, or non-segregating. A total of 65 segregating and 31 non-segregating CNVRs identified in at least 10 individuals within a dense pedigree of the Gochu Asturcelta pig breed was subjected to enrichment and functional annotation analyses to ascertain their functional independence and importance. Enrichment analyses allowed us to annotate 1018 and 351 candidate genes within the bounds of the segregating and non-segregating CNVRs, respectively. The information retrieved suggested that the candidate genes spanned by segregating and non-segregating CNVRs were functionally independent. Functional annotation analyses allowed us to identify nine different significantly enriched functional annotation clusters (ACs) in segregating CNVR candidate genes mainly involved in immunity and regulation of the cell cycle. Up to five significantly enriched ACs, mainly involved in reproduction and meat quality, were identified in non-segregating CNVRs. The current analysis fits with previous reports suggesting that segregating CNVRs would explain performance at the population level, whereas non-segregating CNVRs could explain between-individuals differences in performance.

“…They are resistant and adapt to the environment easily. Gochu Asturcelta pigs have been traditionally reared in the extensive system in Ibero-Atlantic deciduous forests [56,57]. The origin of the Majorcan Black breed is uncertain, but the existence of pig livestock in Mallorca dates back to the period of the first settlers, approximately 3500 BC.…”

The purpose of this paper is to summarize the available important information on local pig breeds maintained in Europe. Genetic erosion has prompted national and international bodies to take organized action aimed at the minimization of further losses of biodiversity. Since the genetic resources of livestock ensure both food security and the sustainable development of rural areas, genetic diversity is indispensable for sufficient flexibility of future animal husbandry to adapt to changing consumer demands and climatic conditions. Therefore, the problem of biodiversity has recently become an essential part of the comprehensive international program of the World Conservation Strategy and the global idea of the so-called sustainable development. The issue of biodiversity protection occupies an important place in the provisions of the EU Common Agricultural Policy. The successive financial perspectives assume an increase in relevant expenditure from the EU and national budgets. With regard to the protection of native pig breeds, a particularly large increase in funding was recorded in 2014–2020.

“…The skin colour shows a great variety; the Gochu Asturcelta population can have white, black, or spotted coats, and some appear to have belt-like patterns. The breed risked extinction in the 20th century and was revived only recently [37]. The SDG local risk status is defined as "at risk" with "endangered maintained".…”

Belted pig breeds have unique, distinguishing phenotypic characteristics. This review summarises the current knowledge on pig breeds displaying a belted coat pattern. Belts of different widths and positions around the animal’s trunk characterise specific pig breeds from all around the world. All the breeds included in the present paper have been searched through the FAO domestic animal diversity information system (DAD-IS), Every country was checked to identify all breeds described as having black or red piebald coat pattern variations. Advances in genomic technologies have made it possible to identify the specific genes and genetic markers associated with the belted phenotype and explore the genetic relationships between different local breeds. Thus, the origin, history, and production traits of these breeds, together with all the genomic information related to the mechanism of skin pigmentation, are discussed. By increasing our understanding of these breeds, we can appreciate the richness of our biological and cultural heritage and work to preserve the biodiversity of the world’s animals.
