Repeatability of ultrasound-predicted percentage intramuscular fat was studied using observations from 144 head of cattle. Animals were scanned at an average age of 433-d by a certified technician. Each animal was scanned five times using two Aloka 500V machines. Percent intramuscular fat was then predicted by placing a box at two different positions within an image. Overall standard deviation ...

CGRP, which coexists with acetylcholine in trigeminal motoneurons, could be one of the regulatory anterograde factors responsible for the enhanced expression of AChR subunits in neuromuscular junction. It has been also shown that low level of thyroid hormone plasma concentration has influence on the transitional development of muscle fibers and related motoneurons through a sever reduction in A...

The aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of Romanian Simmental dairy cattle. For the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...

background and objectives: sarcopenia is explained as age-related reduction in muscle mass and performance. some of the most important risk factors for sarcopenia include age, malnutrition, and sedentary life style. the aim of this study was to investigate the association of food intake and physical activity with body composition, muscle strength and muscle function in post-menopausal women. ma...

Body Mass Index (BMI) is a weight-to-height ratio used as a quick and easy guide to obesity classification. BMI of 30 or greater is indicative of excess body fat and has been labelled as increasing the risk of degenerative diseases such as cardiovascular disease and diabetes. Body fat percentage is also assessed through skinfold thickness measurement.. The aim of this study was to estimate the ...
