Intramuscular fat (IMF) content depends on sex, genotype and diet and varies with pig growth. The aim of the present work was to determine the evolution of IMF by genotype-sex, muscle and muscle location, to determine relationships between IMF content of different muscles and to predict IMF in live pigs with computed tomography (CT). For this purpose, 155 pigs of seven combinations of genotype-sex were CT scanned and slaughtered at 70, 100 and 120 kg. From the carcasses, fat thickness was measured at several locations along the midline...

Properties of skipjack tuna loins subjected to high-pressure processing (HPP) at 150 to 600 MPa for 1 to 5 min were compared with those of loin that underwent steam cooking for 10 min. Protein denaturation in HPP-treated loins increased with increasing pressure level, but these loins retained between 1.1% and 2.4% more water than steam-cooked loin. Water holding capacity decreased from 57% to 44% when the loins were treated at 600 MPa. ΔE value of HPP loins was between 5.8 and 26.3 when treated at 150 to 600 MPa, whereas it was 34...

The purpose of this study was to evaluate the clinical characteristics of 44 pediatric patients who were diagnosed as having nutcracker syndrome (NCS). We also investigated the left renal vein Doppler ultrasonography (DUS) results, to determine whether or not there was an association between clinical symptoms and DUS findings among these patients. The clinical data from 44 pediatric patients who were diagnosed as having NCS from January 2008 to December 2015 were retrospectively reviewed. We grouped the patients according to the presenting symptoms as symptomatic (loin pain; macroscopic hematuria or both) and non-symptomatic (microscopic hematuria and proteinuria were detected incidentally) and evaluated the left renal vein DUS indices in these two groups separately...

Today, the U.S. exports 2.2 million t of pork and pork products annually, representing just over 26% of U.S. pork production. In order to meet specific demands of a growing export market, pork quality and carcass characteristics are now integrated into breeding objectives. Color and marbling are two loin quality traits that influence consumer acceptability of pork and while correlations between early and aged ventral quality have been established, it is unclear if those correlations differ between production objectives (meat quality vs...

Selection for beef traits in Italian dual-purpose breeds is often carried out using growth and in vivo conformation recorded on young, performance tested bulls and muscularity traits scored during routinely linear type evaluation on primiparous cows. In this context, the knowledge of the genetic structure of traits obtained in different sexes and at different times is necessary for a proper selection plan. This study aimed to estimate, in the local dual-purpose Rendena breed, the genetic relationships between muscularity linear type traits from primiparous cows, the same traits scored on candidate young bulls, and the performance test traits recorded in candidate young bulls...

Fresh beef color stability is a muscle-specific trait. Mitochondria remain biochemically active in postmortem beef muscles and influence meat color. Although several intrinsic factors governing muscle-specific beef color have been studied extensively, the role of mitochondrial functionality in muscle-dependent color stability is yet to be examined. Therefore, the objective of this study was to examine mitochondrial oxygen consumption rate (OCR), mitochondrial metmyoglobin reducing activity (MMRA), and instrumental color attributes in beef Longissimus lumborum (LL) and Psoas major (PM) during retail display...

This study was conducted to determine whether the application of high pressure processing (HPP) could prevent the process of rigor in fresh pork and to identify the physical and chemical changes occurring in the meat that are responsible for this effect. Pressure (0-400 MPa) and time (10 min) were applied to the pork loin and enzyme samples. The effects of treatment on shear force, myofibrillar fragmentation, enzyme activity and meat texture were measured. The results showed that, compared with untreated samples, HPP treatment inhibited the occurrence of rigor in pork...

This study aimed to determine the effect of frozen-then-chilled storage on free Ca2+ , proteolytic enzyme activity of calpains and the proteasome, water-holding capacity and shear force of porcine longissimus thoracis et lumborum muscle. Pork loins were subjected to either chilled storage at 2 ± 1 °C for 1, 2, 4, 6 and 9 days, or frozen-then chilled storage (-20 ± 1 °C for 1 week followed by thawing overnight). Free Ca2+ increased with chilled storage in the non-frozen group. Frozen-then-chilled storage increased free Ca2+ concentration, followed by a faster decrease of calpain-1 activity and activation of around 50% of calpain-2...

Control and quercetin dihydrate-supplemented (2 g/kg) feeds were fed to 32 New Zealand White rabbits (both sexes) from 5 to 12 weeks old. Slaughter weight, carcass and organ weights, meat yields and physical and proximate meat quality were determined. Quercetin increased the hindleg meat:bone ratio (P < .001) by reducing hindleg bone weight (P = .01), contrary to the current understanding of the effect of quercetin on the skeletal system. However, this and the increase in skin weight (P = ...

Fatty acid-binding protein 4 (FABP4) participates in fatty-acid transportation and variation in the gene has been reported to affect fat deposition in mammals. To assess the effects of variation in FABP4 on carcass and growth traits in sheep, two regions of the gene were investigated in 749 New Zealand Romney lambs. Five variants (A1  - E1 ) were found in region-1 (exon 2 - intron 2) and three variants (A2  - C2 ) were found in region-2 (exon 3 - intron 3). A1 was associated with a decrease in leg meat yield, loin meat yield and total meat yield, whereas A2 was associated with a decrease in weaning-weight and pre-weaning growth-rate...

The objective of this study was to evaluate the effect of dry-aging on meat quality and microbiological properties of grass-fed beef loins. At 7 d postmortem, eighteen bone-in loins (M. longissimus lumborum) from 9 beef carcasses (USDA Select) were obtained. Each loin was cut in half yielding a total of 36 sections, which were assigned to three aging methods: wet-aging (WA); dry-aging (DA); and dry-aging in a water permeable bag (DW). DA resulted in greater shrink and trim loss compared to WA (P < 0...
