Abstract

The European eel, a catadromous endangered species, displays plasticity in phenotypic traits and in trophic behaviour, features that can eventually affect growth. The aim of this study was to compare variation in carbon (δ13C) and nitrogen (δ15N) stable isotopes in muscle tissue of the adult eel life stages (i.e. yellow and silver eel), as function of growth. Eel samples were obtained from nine sites across the Mediterranean region, that included seven coastal lagoons of different size and ecological structure, and two freshwater habitats corresponding to one river and one lake. A large variability was found in both δ13C and δ15N values, suggesting that eels fed over a broad range of potential food sources. Eels from each location showed specific range values of δ13C, in most sites irrespective of stage, reflecting lagoon- or freshwater-specific carbon sources. A positive correlation was found between individual δ15N values and annual growth rates, suggesting that eels generally seem to feed on prey of higher δ15N values among the trophic resources available in each foraging habitat. This allows individuals to grow faster and to attain earlier the pre-spawning phase (i.e. the silver stage). A better understanding of eel trophic ecology across different life stages and different habitats is one of the prerequisites for the effective management of local stocks.

Abstract

The majority of organic marine fish farms currently begin the production cycle with non-organic juveniles from conventional hatcheries, permitted by the European Regulation on organic fish origin (EC 710/2009) until the end of 2016. Wild juvenile gilthead seabream (Sparus aurata) from coastal lagoons and hatcheries were experimentally reared under organic conditions, in order (1) to investigate differences in fillet lipid content and fatty acids composition, and (2) to propose a possible future source of juveniles destined for organic aquaculture. Wild juveniles were readily distinguishable by their fatty acid signature, showing significantly higher ratio levels of n-3 polyunsaturated fatty acids and n-3/n-6. Fillet lipid composition of organically fed wild S. aurata juveniles was preferable to that from domesticated juveniles. These results seem promising for organic aquaculture, where fish feed is more environmentally sustainable but is of lower nutritional quality

Abstract

The melanocortin-4 receptor (MC4R) gene codes for a G protein transmembrane receptor playing an important role in energy homeostasis control. In pig a single nucleotide polymorphism c.1426G>A has been identified and associated to average daily gain, feed intake and fatness traits but a lack of agreement on the effects of the gene on carcass traits in different breeds comes out from many studies. In the present study the c.1426G>A polymorphism is analysed in two Italian pig breeds, Large White and Duroc to study the association of the MC4R gene with some carcass traits. The results show that the c.1426G>A polymorphism affects daily gain, feed conversion ratio and ham weight in both breeds, lean cuts in the Italian Duroc and backfat thickness in the Italian Large White. The presence of MC4R mRNA transcript in different porcine tissues was analysed.

Abstract

The aim of this study was to evaluate the effects of single nucleotide polymorphisms (SNPs) and haplotypes in porcine calpastatin (CAST) gene on performance and carcass traits in Italian Large White (ILW) pigs. Seven SNPs located from promoter to exon 17 of CAST gene were genotyped by the Illumina GoldenGate genotyping assay in 280 ILW pigs and seven haplotypes were inferred from four informative SNPs. Association analyses were performed for SNPs and haplotypes with performance and carcass estimated breeding values in the ILW population. Significant association (P

Abstract

PLIN2 (perilipin 2) is a cytosolic protein that promotes the formation and stabilization of the intracellular lipid droplets, organelles involved in the storage of lipid depots. Porcine PLIN2 gene represents a biological and positional candidate for fat deposition, a polygenic trait that affects carcass and meat quality. The aim of the present study was to screen PLIN2 gene for polymorphisms, to evaluate the association with carcass quality traits, and to investigate the gene expression in skeletal muscle. Six new single nucleotide polymorphisms (SNP) were detected by sequencing 32 samples from five pig breeds (Italian Large White, Italian Duroc, Italian Landrace, Belgian Landrace, Pietrain). Two SNP localized in introns, two in the 3′-untranslated region (UTR), and two missense SNP were found in exons. A 3′-UTR mutation (GU461317:g.98G>A), genotyped in 290 Italian Duroc pigs by High Resolution Melting, resulted significantly associated (P < 0.01) with average daily gain, feed conversion ratio, lean cuts and hams weight estimated breeding values. PLIN2 gene expression analysis in skeletal muscle of Italian Large White and Italian Duroc pigs divergent for backfat thickness and visible intermuscular fat showed a trend of higher expression level in pigs with higher intermuscular fat. These results suggest that PLIN2 can be a marker for carcass quality in pigs. Further investigation at both gene and protein level could elucidate its role on fat deposition.

Abstract

The adiponectin (adiponectin, C1Q and collagen domain containing) encoded by ADIPOQ is an adipokine that modulates several biological processes such as lipogenesis, gluconeogenesis, fatty acid oxidation, glucose uptake and insulin sensitivity. An objective of this study was to identify SNPs in the ADIPOQ gene both in cosmopolitan and local pig breeds reared in Italy and in Meishan samples. Resequencing of ADIPOQ gene regions in 16 pigs of 12 breeds revealed only two SNPs ( EU489740 : g.1611G > A synonymous and EU489740 : g.1735G > A missense mutations) already reported. The g.1735G > A polymorphism was genotyped by PCR-RFLP in 510 pigs from 11 breeds reared in Italy (Italian Large White, Italian Duroc, Italian Landrace, Belgian Landrace, Hampshire, Pietrain, Calabrese, Casertana, Cinta Senese, Mora Romagnola and Nero Siciliano) and from Chinese Meishan breed. The Italian local breeds were homozygous for the g.1735G allele while the Meishan samples resulted homozygous for the g.1735A allele. The polymorphism segregates in the cosmopolitan breeds, except for Hampshire, and the rarer g.1735A allele showed the highest frequency in Italian Duroc (0.12). Association analysis of g.1735G > A polymorphism with estimated breeding values (EBVs) for average daily gain (ADG), feed:gain ratio (FGR), weight of neck and loin (lean cuts, LC), weight of ham (H) and backfat thickness (BFT) were performed in Italian Duroc heavy pigs. The GA vs GG pigs showed higher least square means for ADG ( P = 0.003) and LC ( P = 0.036) EBVs and lower value for FGR EBV ( P = 0.033).

Abstract

Association mapping of the central part of porcine chromosome 2 harboring QTLs for carcass and meat quality traits was performed with 17 gene-tagged SNPs located between 44.0 and 77.5 Mb on a physical map (Sscrofa102) in Italian Large White pigs. For the analyzed animals records of estimated breeding values for average daily gain, back fat thickness, lean cuts, ham weight, feed conversion ratio, pH(1), pH(u), CIE L*, CIE a*, CIE b* and drip loss were available. A significant QTL for fat deposition (adjusted P = 0.0081) and pH(1) (adjusted P = 0.0972) to MYOD1 at position 44.4 Mb and a QTL for growth and meatiness (adjusted P = 0.0238-0.0601) to UBL5 at position 68.9 Mb were mapped. These results from association mapping are much more accurate than those from linkage mapping and facilitate further search for position candidate genes and causative mutations needed for application of markers through marker assisted selection.
