Ellagitannin-containing foods (strawberries, walnuts, pomegranate, raspberries, oak-aged wine, etc.) have attracted attention due to their cancer chemopreventive, cardioprotective, and antioxidant effects. Ellagitannins (ETs) are not absorbed as such but metabolized by the intestinal flora yield urolithins (hydroxydibenzopyran-6-one derivatives). In this study, Iberian pig is used a model clarify human ET metabolism. Pigs were fed either cereal fodder or acorns, rich source of ETs. Plasma,...
Iberian ham production includes both purebred (IB) and Duroc-crossbred (IBxDU) pigs, which show important differences in meat quality traits, such as muscle growth fatness. This experiment was conducted to investigate gene expression differences, transcriptional regulation genetic polymorphisms that could be associated with the observed phenotypic between IB IBxDU pigs. Nine 10 pigs were slaughtered at birth. Morphometric measures blood samples obtained from Biceps femoris employed for...
The two main genetic types in Iberian pig production show important phenotypic differences growth, fattening and tissue composition since early developmental stages. objective of this work was the evaluation muscle transcriptome profile piglets both types, order to identify genes, pathways regulatory factors responsible for their differences. Contemporary families coming from pure pigs (IB) or crossing with Duroc boars (DU×IB) were generated. Piglets (14 each type) slaughtered at weaning (28...
The effect of n-3 fatty acid-enriched diets (in the form 0.5% linseed oil with either 1.5% sunflower or olive oil) and α-tocopheryl acetate supplementation (200 mg/kg feed) on lipid oxidation (thiobarbituric acid-reactive substances, TBARS) cholesterol oxide products (COPS) in cooked pork was investigated. Longissimus muscle studied. Meat from pigs fed oil-enriched had a higher proportion acid than meat other dietary groups neutral (P < 0.0001) polar lipids 0.0001), 20% reduction n-6:n-3...
Iberian pig production includes purebred (IB) and Duroc-crossbred (IBxDU) pigs, which show important differences in growth, fattening tissue composition. This experiment was conducted to investigate the effects of genetic type muscle (Longissimus dorsi (LD) vs Biceps femoris (BF)) on gene expression transcriptional regulation at two developmental stages. Nine IB 10 IBxDU piglets were slaughtered birth, seven four months age (growing period). Carcass traits LD intramuscular fat (IMF) content...
The distribution of NADPH-diaphorase (ND) activity was histochemically investigated in the brain frog Rana perezi. This technique provides a highly selective labeling neurons and tracts. In telencephalon, labeled cells are present olfactory bulb, pallial regions, septal area, nucleus diagonal band, striatum, amygdala. Positive surround preoptic infundibular recesses third ventricle. magnocellular suprachiasmatic hypothalamic nuclei contain stained cells. Numerous anterior, lateral central,...
This study evaluates the effect of organic (Se-enriched yeast; SeY) versus inorganic selenium (sodium selenite; SeS) supplementation and different response source according to muscle pH on pork meat quality characteristics. Pigs (n = 30) were fed Se-supplemented diets (0.3 mg/kg) for 65 days. Neither electric conductivity (EC) nor drip loss affected by source. The SeY group had lower TBARS in samples after day 7 refrigerated storage higher a* values days 1 than SeS group. dietary some...
To meet the demand for chicken meat production, new additives that promote growth and health without adverse effects on quality are being investigated. This study was conducted to investigate effect of protected sodium butyrate (PSB) (0 vs. 2 g/kg), an olive leaf grape-based by-product (OLG-mix), or a combined supplementation PSB OLG-mix productive performance, antioxidant status, carcass, in broilers. improved performance parameters with greater initial phase. Both, increased plasma...
Abstract The effects of olive (MONO) or sunflower (POLY) oil-enriched (30 g/kg) diets with either a basal (10 mg/kg food) supplemented (200 mg/kg) level a-tocopheryl acetate on some measures production, fatty acid composition animal tissues and susceptibility to oxidation rabbit meat membrane extracts have been studied. MONO diet produced higher levels C18:1 in tissues. Animals that received POLY had C18:2 perirenal neutral fraction intramuscular fat C18:2, C20:4, C22:4 C22:5 phospholipid,...
Abstract The effect of extensive feeding, confinement and diet supplementation with a-tocopheryl acetate (100 mg/kg) on the fatty acid composition tocopherol concentration microsome extracts their susceptibility to oxidation was studied in Iberian pigs. pigs raised extensively mostly composed acorn grass. a-tocopherol contents grass were 20 171 mg/kg dry matter, respectively. Microsomal showed no differences among groups. Pigs feeding had a higher muscle microsomes than given mixed basal...
It has been proposed that dietary linoleic acid lowers blood pressure (BP) by being converted to arachidonic and prostanoids of the two-ene series. We tested effects on plasma acid, pressure, viscosity, RBC cation transport. Oleic major monounsaturated fat which is not a prostanoid precursor, was used as control. Seventeen adults consumed 23 g/d or oleic provided genetic variants safflower seed, each for 4 weeks in double-blind crossover design. Linoleic acids were enriched significantly...
This study evaluates the effect of source dietary selenium supplementation (organic versus mineral) and combined organic vitamin E on fatty acid composition lipolysis in pork intramuscular fat other meat quality characteristics such as drip loss lipid stability. Higher deposition, lower loss, higher stability against oxidation were detected muscle from pigs fed selenium. Also proportion free acids was observed than those inorganic selenium, being these mainly coming neutral fraction. In...
Grape byproducts are rich sources of polyphenols with powerful antioxidant and health-promoting effects. The impact supplementing chicken diets grape on plasma thigh meat concentrations phenolic metabolites was evaluated by analyzing samples high-performance liquid chromatography quadrupole time flight mass spectrometry. Chickens were fed three experimental diets: Control diet, Control+8% pomace, Control+0.1% seed extract. In plasma, 32 identified, some which conjugated catechin/epicatechin...
Olive tree leaves are characterized for having not only a potent antioxidant power but also effects on glucose and lipid metabolism. The impact of the individual oleuropein (OLE), vitamin E + Se (VE), or combined supplementation oleuropein, E, selenium (VEOLE) was evaluated pig plasma metabolites under fasting prior to slaughter. VEOLE OLE had lesser n-3 polyunsaturated fatty acids greater monounsaturated free compared control. n-3-fatty acid mobilization directly correlated with cystine...
Abstract Iberian pigs and its crosses are produced to obtain high-quality meat products. The objective of this work was evaluate a wide panel DNA markers, selected by biological functional criteria, for association with traits related muscle growth, fatness, quality metabolism. We used 18 crossbred divergent postnatal growth patterns whole genome sequencing SNP discovery, over 13 million variants being detected. 1023 missense SNPs located on annotated genes showing different allele...
The objective of this study was to assess the effect dietary copper and/or vitamin E supplementation on composition and oxidation M. longissimus in Iberian pigs compare it with meat samples from produced extensively fed acorn grass. Grass had highest α‐tocopherol content (> 150 mg/kg DM), while acorns concentration (78.1 DM). Dietary treatment did not affect muscle no interactions were detected between α‐tocopherol. diets supplemented α‐tocopheryl acetate (100 feed) 1.5 times greater (p...
