Fatty Acid and Transcriptome Profiling of Longissimus Dorsi Muscles between Pig Breeds Differing in Meat Quality
Fat and lean pig breeds show obvious differences in meat quality characteristics including the fatty acid composition of muscle. However, the molecular mechanism underlying these phenotypes differences remains unknown. This study compared meat quality traits between Lantang (a Chinese indigenous breed) and Landrace (a typical lean breed). The Lantang pigs showed higher L* values and intramuscul...
متن کاملComparative Analyses by Sequencing of Transcriptomes during Skeletal Muscle Development between Pig Breeds Differing in Muscle Growth Rate and Fatness
Understanding the dynamics of muscle transcriptome during development and between breeds differing in muscle growth is necessary to uncover the complex mechanism underlying muscle development. Herein, we present the first transcriptome-wide longissimus dorsi muscle development research concerning Lantang (LT, obese) and Landrace (LR, lean) pig breeds during 10 time-points from 35 days-post-coit...
متن کاملSlow fiber cluster pattern in pig longissimus thoracis muscle: implications for myogenesis.
Recent evidence implicates fiber type proportions as playing a role in meat eating quality, and in pigs it has been suggested that the slow oxidative fibers contribute to both juiciness and tenderness. The fiber distribution in pigs is different from that found in most other species, in which the various types of skeletal muscle fiber are distributed in a "checkerboard" pattern, because in pigs...
متن کاملRelationships between muscle fibre characteristics and physico-chemical properties of longissimus lumborum muscle and growth rate in pig fatteners of three breeds*
In 40 Polish Landrace, 38 Polish Large White and 14 Pietrain fatteners the longissimus lumborum (LL) muscle fibres were characterized and LL quality indicators determined. The correlation was estimated between the LL fibres traits and daily live weight gain, muscle pH and texture parametres. Muscle fibres were identified as I, IIA and IIB types based upon their dehydrogenase (NADH) activity. Th...
متن کاملThe effects of sex and slaughter weight on muscle fibre characteristics and physico-chemical properties of lamb longissimus thoracis muscle
The objective was to investigate the effect of sex and slaughter weight on muscle fibre and meat quality traits of longissimus thoracis (LT) muscle in lambs. Used were 22 female and 30 male lambs of Polish Longwool sheep from two slaughter weight groups: I – 15-20 kg and II – 25-30 kg. LT muscle samples were taken to categorize fibre types (I, IIA and IIB) according to their NADHtetrazolium red...
