Ultrasonographic in vivo estimation of back fat depth and Longissimus dorsi area in Iberian pigs
Real-time ultrasound is a useful technology for measuring carcass composition in live animals and to select future seedstock for carcass merit. Therefore, the objective of this study was to evaluate the use of ultrasound to predict the amount of fat and muscle in Iberian pigs. A total of 163 Iberian pigs were ultrasonically scanned one day before slaughter, and carcass composition was also dete...
متن کاملTranscript profiles in longissimus dorsi muscle and subcutaneous adipose tissue: a comparison of pigs with different postweaning growth rates.
Although most pigs recover rapidly from stresses associated with the transition of weaning, a portion of the population lags behind their contemporaries in growth performance. The underlying biological and molecular mechanisms involved in postweaning differences in growth performance are poorly understood. The objective of this experiment was to use transcriptional profiling of skeletal muscle ...
متن کاملExpression of myogenes in longissimus dorsi muscle during prenatal development in commercial and local Piau pigs
This study used qRT-PCR to examine variation in the expression of 13 myogenes during muscle development in four prenatal periods (21, 40, 70 and 90 days post-insemination) in commercial (the three-way Duroc, Landrace and Large-White cross) and local Piau pig breeds that differ in muscle mass. There was no variation in the expression of the CHD8, EID2B, HIF1AN, IKBKB, RSPO3, SOX7 and SUFU genes ...
متن کاملPhysicochemical properties of M. longissimus dorsi of Korean native pigs
Background The meat quality of Korean native pigs (KNP) and crossbred pigs (LYD; Landrace × Yorkshire × Duroc) was examined to generate data useful for selecting native pigs for improved pork production. Methods Fifty Korean native pigs (KNP) and 50 crossbred pigs (LYD) were tested. Loin samples (M. longissimus dorsi) of the two breeds were analyzed to determine meat quality and sensory prope...
متن کاملMitochondrial genome polymorphisms associated with longissimus muscle composition in Iberian pigs.
We carried out a study to investigate the associations between mitochondrial DNA polymorphisms and meat quality traits (intramuscular fat and protein content of the longissimus) in an Iberian porcine line named Torbiscal. The studied pigs (n = 319) belong to 9 maternal lineages and were previously assigned to 6 mitochondrial haplotypes (H1 to H6), based on Cytochrome b and Dloop sequences. Stat...
