Muscle Fibre Architecture of Thoracic and Lumbar Longissimus Dorsi Muscle in the Horse

Comparison of the Fatty Acid Composition of the Longissimus Dorsi Muscle of Kids, Lambs and Calves Produced under Iranian Transhumant Production System

Transhumant production system (TPS) is a type of extensive livestock production practiced by transhumant pastoralists in which indigenous livestock breeds are mainly fed a pasture-based diet. The hypothesis tested in this work was whether differences existed between fat samples from the different species in respect to ratios of n-6/n-3, and polyunsaturated fatty acids to saturated fatty acids. ...

Sequencing and Characterization of Divergent Marbling Levels in the Beef Cattle (Longissimus dorsi Muscle) Transcriptome

Marbling is an important trait regarding the quality of beef. Analysis of beef cattle transcriptome and its expression profile data are essential to extend the genetic information resources and would support further studies on beef cattle. RNA sequencing was performed in beef cattle using the Illumina High-Seq2000 platform. Approximately 251.58 million clean reads were generated from a high mar...

The Anatomy and Function of the equine thoracolumbar Longissimus dorsi muscle

Expression 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 ...

Expression of ADAMTS4 and ADAMTS5 in longissimus dorsi muscle related to meat tenderness in Nanyang cattle.

The ADAMTS4 and ADAMTS5 are secreted proteases, which can cleave aggrecan, brevican and versican to regulate rebuilding of the extracellular matrix. We analyzed the ADAMTS4 and ADAMTS5 gene expression patterns in longissimus dorsi muscle at intervals from 135 days fetal age to 30 months old by qRT-PCR in Nanyang cattle. Expression of ADAMTS4 was significantly higher in 135 and 185-day-old fetus...
