Quantitative descriptions of muscle architecture are needed to characterize the force-generating capabilities of muscles. This study reports the architecture of three major trunk muscles: the rectus abdominis, quadratus lumborum, and three columns of the erector spinae (spinalis thoracis, longissimus thoracis and iliocostalis lumborum). Musculotendon lengths, muscle lengths, fascicle lengths, s...

Concern about pork quality has increased during last decades. Given the influence of fat content and composition on sensorial, nutritional, and technological variables of pork meat, an accurate knowledge about genetic control of pig lipid metabolism is required. This study focused on providing a broad characterization for serum and meat lipid trait heritability estimates in pigs. Analyses were ...

The objectives of this study were to determine 1) the effectiveness of calcium chloride when injected later than 2 d postmortem, 2) the effect of extended postinjection aging time, and 3) the tenderness response curve in calcium chloride-treated beef. In Exp. 1, the longissimus thoracis et lumborum was injected on either d 2 or 14 postmortem with 5% by weight of a 200 mM calcium chloride soluti...

Visible and near infrared reflectance spectroscopy was used to predict pH at 24h (pH24) post-mortem, sarcomere length (SL), cooking loss (CL), Warner-Bratzler Shear Force (WBSF) and colour parameters (L(∗), a(∗), b(∗)) in beef cattle samples. Samples from M. longissimus thoracis et lumborum from 30 bulls were aged at 4°C for 1, 3, 7 and 14 days and analysed for pH, SL, CL, WBSF and colour. NIRS...

The influence of protein phosphorylation on meat color stability was investigated in this study. Phosphatase and protein kinase inhibitors were added to minced ovine Longissimus thoracis et lumborum (LTL) muscle to manipulate the global phosphorylation of sarcoplasmic proteins. The data obtained show that the rate and extent of pH decline, along with lactate accumulation in postmortem muscle, w...

We studied the effect of a high linolenic acid diet supplementation with synthetic (vitamin E + selenium) or veg-etal mix rich in natural antioxidants (grape skin oregano) on live performances, carcass and meat quality, fatty composition oxidative stability intramuscular lipids Longissimus thoracis et lumborum muscle medium-heavy pigs. Neither traits nor chemical proximate was affected by dieta...

This study analyzed the chemical composition and β-carotene, tocopherol retinol content of meat (musculus longissimus lumborum, musculus gluteus maximus) from young rams fed different silage-based diets. The animals were divided into four groups depending on type silage in feed ration (hybrid ryegrass, Festulolium cv. Becva, Felopa, Paulita). concentrations examined lipophilic compounds measure...

The objective of the study was to analyse fatty acid profile (FA) and amino (AA) in musculus longissimus lumborum et thoracis (MLLT) two contrast pig populations. carried out on a total 39 pigs (19 barrows 20 gilts) indigenous Prestice Black-Pied Pig (PB) 37 (17 three-breed commercial hybrid Large White × Landrace Whitesireline (CH). were kept same conditions diet management. slaughter at avera...

The aim of this study was to examine carcass properties and variability in chemical content and fatty acid composition in the musculus longissimus lumborum et thoracis (MLLT) of different genotypes of pigs. Of 36 male castrated animals used in the trial, 24 were from two strains of Mangalitsa pigs (12 Swallow bellied (SBM) and 12 White (WM)), while 12 were of the Swedish Landrace (SL) breed (th...
