The Intensity of MLLT Area Changes and Development of the Selected Body Parts Muscling in Bulls and Heifers of Blonded’ Aquitaine Cattle and its Crossbreeds During Rearing Period
The objective of this work was to determine the effect of sex, breed and birth season of calves on intensity of MLLT (musculus longissimus lumborum et thoracis) area changes and development of the selected body parts in bulls and heifers of Blonde d´Aquitaine (BA) cattle during rearing period. Two generations of bulls (n=63) and heifers (n=68) of Blonde d´Aquitaine (n=61) and crossbreds C×BA (C...
متن کاملThe use of visible and near infrared reflectance spectroscopy to predict beef M. longissimus thoracis et lumborum quality attributes.
Visible and near infrared reflectance spectroscopy was used to predict pH at 24h (pH24) post-mortem, sarcomere length (SL), cooking loss (CL), Warner-Bratzler Shear Force (WBSF) and colour parameters (L(∗), a(∗), b(∗)) in beef cattle samples. Samples from M. longissimus thoracis et lumborum from 30 bulls were aged at 4°C for 1, 3, 7 and 14 days and analysed for pH, SL, CL, WBSF and colour. NIRS...
متن کاملGenetic parameter estimates for serum insulin-like growth factor-I concentration and ultrasound measurements of backfat thickness and longissimus muscle area in Angus beef cattle.
A divergent selection experiment for serum IGF-I concentration began at the Eastern Ohio Resource Development Center in 1989 using 100 spring-calving (50 high line and 50 low line) and 100 fall-calving (50 high line and 50 low line) purebred Angus cows. Following weaning, bull and heifer calves were fed in drylot for a 140-d period. Real-time ultrasound measurements of backfat thickness and lon...
متن کاملHigh-starch diets induce precocious adipogenic gene network up-regulation in longissimus lumborum of early-weaned Angus cattle.
Adipocyte differentiation is probably controlled by transcriptional and post-transcriptional regulation. Longissimus lumborum from Angus steers (aged 155 d; seven animals per diet) fed high-starch or low-starch diets for 112 d (growing phase) followed by a common high-starch diet for an additional 112 d (finishing phase) was biopsied at 0, 56, 112 and 224 d for transcript profiling via quantita...
متن کاملSheep carcass composition estimated from Longissimus thoracis et lumborum muscle volume measured by in vivo real-time ultrasonography.
The use of Longissimus thoracis et lumborum muscle (LM) volume measured in vivo by real-time ultrasonography (RTU) to estimate carcass composition was evaluated in 47 female sheep. Animals were scanned over six sites (7th, 9th, 11th and 13th thoracic vertebrae and 2nd and 4th lumbar vertebrae). After slaughter carcass weight (CW) and composition by dissection were determined. RTU volume measure...
