Carcass and meat quality of Thai native cattle, fattened for 2 years on Guinea grass (Panicum maxima) and Guinea grass-legume (Stylosanthes guianensis) pastures, were investigated in twelve 3-years old males. Groups had similar carcass quality except for kidney fat percentage (higher in cattle of the grass-legume group). This group also had a lighter meat (Longissimus dorsi, Infraspinatus) than...

One hundred and four pure-bred Norwegian Duroc boars were CT (computed tomography) scanned to predict the in vivo intramuscular fat percentage in the loin. The animals were slaughtered and the loin was cut commercially. A muscle sample of the m. Longissimus dorsi was sampled and analyzed by the use of near-infrared spectroscopy. Data from CT images were collected using an in-house MATLAB script...

The nutritive utilization of magnesium and calcium was studied using two different formulations of Mg: MgCO3 and an organic dietary Mg preparation. The influence of supplementation with the latter was also studied. The dietary organic magnesium did not modify food intake, which remained adequate in all animals used in the present experiments. Magnesium in both inorganic compound and organic pre...

This study determined effect of automobile seat backrest inclination on lattisimus dorsi muscle electromyographic (EMG) activity. Myoelectric activity was determined at two seat backrest angles (90 degrees and 100 degrees inclinations).  Twenty-one (21) participants were engaged in the study. Electromygraphic activity at 90 degrees inclination had slope value of -0.065 mV/minute while ...

OBJECTIVE The purpose of this study was to investigate the influence of AMP-activated protein kinase (AMPK) activation on protein acetylation and glycolysis in postmortem muscle to better understand the mechanism by which AMPK regulates postmortem glycolysis and meat quality. METHODS A total of 32 mice were randomly assigned to four groups and intraperitoneally injected with 5-Aminoimidazole-...

Epigenetic factors, such as DNA methylation status, may regulate adipogenesis and lipogenesis, thus affecting intramuscular fat (IMF) deposition in longissimus dorsi muscle (LM) of beef cattle. In Korean cattle steers, the LM consists mainly of muscle tissue. However, the LM tissue also contains IMF. We compared the gene expression levels between the IMF and muscle portions of the LM after tiss...

Skeletal muscle protein synthesis is reduced in neonatal pigs in response to endotoxemia. To examine the role of insulin in this response, neonatal pigs were infused with endotoxin (LPS, 0 and 10 mug.kg(-1).h(-1)), whereas glucose and amino acids were maintained at fasting levels and insulin was clamped at fasting or fed (2 or 10 muU/ml) levels. Fractional rates of protein synthesis and transla...

The aim of this study was to determine the relationships among muscle fiber-type composition, fiber diameter, and myogenic regulatory factor (MRF) gene expression in different skeletal muscles during development in naturally grazing Wuzhumuqin sheep. Three major muscles (i.e. the Longissimus dorsi (LD), Biceps femoris (BF) and Triceps brachii (TB)) were obtained from 20 Wuzhumuqin sheep and 20 ...

bovine hypodermosis is a myiasis caused by larvae of hypoderma bovis and h. lineatum which are commonly known as grubs. as different insecticide pour-on treatments and sc ivermectin, which must be in direct contact with larvae, are used in larvae controlling programs, therefore, determining the exact topography of the most probable regions of larval presence is of great importance and it could ...

Background: The latissimus dorsi muscle flap is one of the most commonly used surgical options for breast reconstruction. The donor area scar on the back, although sometimes hidden beneath the bra strap, is often extensive and enlarged or hypertrophic. The aim of this study is to describe the dissection and rotation of the latissimus dorsi muscle using 2 reduced vertical incisions. Methods: Twe...
