“…In summary, the higher number of products of recognised quality reflects both the great appreciation in Spain for natural and artisanal pork products and the recognition of the high value of the country's rural food heritage. This type of farming also fits in perfectly with the emphasis given to animal welfare and, more particularly, with environmentally friendly farming (Aparicio et al, 2018) and the strategy for sustainable and natural livestock farming systems. Thus, extensive pig farming models (dehesa pigs) have the best agro-ecological credentials for energy return on investment (EROI), contributing to the energy transition and offering organic meat to society (Ramos et al 2022).…”

The economic success of the intensive poultry and pork sectors is a milestone in the Spanish economic history of the past seven decades. This work analyses the boom in the chicken and pork businesses in Spain, verifying the strengths and weaknesses of both livestock models, and drawing conclusions in relation to the agribusiness system. The influence of chicken and pork in the booming Spanish meat sector is analysed from the perspectives of livestock farming and agroindustry, followed by the impact of both forms of intensive livestock farming on Spain’s domestic consumption and foreign trade. The similarities and differences in their evolution are identified from the perspective of two food supply models: a predominance of economies of scale until the 1980s, and of so-called economies of scope since that time. While the development of mass production in both intensive livestock businesses followed a similar pattern, the progressive segmentation of the market towards higher quality, more artisanal and sustainable products has greatly favoured the sector more deeply rooted in rural tradition: pork.

“…Although the Gochu Asturcelta and Bísara breeds are thought to have common ancestors (Aparicio, 1944), the patterns of nucleotide variation caused by recent drift due to a population bottleneck may mimic those caused by selection pressures at specific loci (Hohenlohe et al, 2010; Oleksyk et al, 2010), and therefore, we have used a very conservative approach to identify genomic regions putatively specific to the Celtic‐Iberian pig strain. Particularly, because of populations with significant levels of inbreeding, the identification of breed‐specific characteristics may be difficult (Schiavo et al, 2021).…”

“…In 2002, a conservation programme for the Gochu Asturcelta was initiated using six founders (Menéndez et al, 2015; Menéndez, Álvarez, et al, 2016). Addressing this gap is important because Celtic‐Iberian pigs were majority in Spain and Portugal until the 1950s (Aparicio, 1944; Santos Silva et al, 2019). Recovery programmes for the Celtic‐Iberian pig breeds were implemented only recently: the programme for the Portuguese Bísara breed started in 1996 by implementing two governmental‐run conservation nuclei in Guimarães and Montalegre (Santos Silva et al, 2019).…”

“…Historically, two different pig strains were bred in the Iberian Peninsula (Aparicio, 1944; Sotillo & Serrano, 1985): the Celtic and the Iberian pig breeds. The Iberian and Lusitano pig breeds are hypothesized to result from a particular domestication event occurred in the Iberian Peninsula, whereas Celtic‐Iberian pigs would result from an ancient process of migration of Northern‐Central European pigs, with population replacement, into the Iberian Peninsula (Aparicio, 1944; Sotillo & Serrano, 1985). Such hypotheses are consistent with genetic data (Menéndez, Goyache, et al, 2016).…”

Celtic‐Iberian pig breeds were majority in Spain and Portugal until the first half of the 20th century. In the 1990s, they were nearly extinct as a result of the introduction of foreign improved pig breeds. Despite its historical importance, the genetic background of the Celtic‐Iberian pig strain is poorly documented. In this study, we have identified genomic regions that might contain signatures of selection peculiar of the Celtic‐Iberian genetic lineage. A total of 153 DNA samples of Celtic‐Iberian pigs (Spanish Gochu Asturcelta and Portuguese Bísara breeds), Iberian pigs (Spanish Iberian and Portuguese Alentejano breeds), Cinta Senese pig, Korean local pig and Cosmopolitan pig (Hampshire, Landrace and Large White individuals) were analysed. A pairwise‐comparison approach was applied: the Gochu Asturcelta and the Bísara samples as test populations and the five other pig populations as reference populations. Three different statistics (XP‐EHH, FST and ΔDAF) were computed on each comparison. Strict criteria were used to identify selection sweeps in order to reduce the noise brought on by the Gochu Asturcelta and Bísara breeds' severe population bottlenecks. Within test population, SNPs used to construct potential candidate genomic areas under selection were only considered if they were identified in four of ten two‐by‐two pairwise comparisons and in at least two of three statistics. Genomic regions under selection constructed within test population were subsequently overlapped to construct candidate regions under selection putatively unique to the Celtic‐Iberian pig strain. These genomic regions were finally used for enrichment analyses. A total of 39 candidate regions, mainly located on SSC5 and SSC9 and covering 3130.5 kb, were identified and could be considered representative of the ancient genomic background of the Celtic‐Iberian strain. Enrichment analysis allowed to identify a total of seven candidate genes (NOL12, LGALS1, PDXP, SH3BP1, GGA1, WIF1, and LYPD6). Other studies reported that the WIF1 gene is associated with ear size, one of the characteristic traits of the Celtic‐Iberian pig strain. The function of the other candidate genes could be related to reproduction, adaptation and immunity traits, indirectly fitting with the rusticity of a non‐improved pig strain traditionally exploited under semi‐extensive conditions.

“…The Gochu Asturcelta pig breed belongs to the Celtic pig strain bred in the Iberian Peninsula [17]. The Celtic-Iberian pigs, which are hypothesized to result from an ancient process of migration of Northern-Central European pigs, with population replacement, into the Iberian Peninsula, were in the majority in Spain and Portugal until the 1950s [17,18]. However, Celtic-Iberian pig breeds, mainly characterized by long, noncompact bodies, good skeletal development, and typically huge ears dropping to the sides of a well-developed head [19], became nearly extinct at the end of the 20th century due to their absorption into and substitution with improved foreign breeds [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.
