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...

The objectives of this study were 1) to determine which longissimus thoracis et lumborum steaks were appropriate for slice shear force measurement and 2) to determine the among and within institution variation in LM slice shear force values of 6 institutions after they received expert training on the procedure and a standard kit of equipment. In experiment 1, longissimus thoracis et lumborum mu...

A novel approach was used to measure the tenderness of prerigor ovine longissimus thoracis et lumborum by avoiding the confounding effects of heat-induced shortening resulting from cooking prerigor meat. The objective was to determine the tenderness of the muscle at the time of slaughter and to monitor changes in tenderness during rigor development and postmortem aging. Nine Romanov and 12 Finn...

In mammals, the epaxial muscles are believed to stabilize the trunk during walking and trotting because the timing of their activity is not appropriate to produce bending of the trunk. To test whether this is indeed the case, we recorded the activity of the m. multifidus lumborum and the m. longissimus thoracis et lumborum at three different sites along the trunk (T13, L3, L6) as we manipulated...

The present study aimed to evaluate the effect of freezing and frozen storage duration (1 4 months) on chemical composition technological properties lamb meat. Meat samples from Musculus Longissimus thoracis et lumborum were collected Bulgarian Dairy Synthetic Population their crosses with Ile-de-France Mouton Charollais breed, a slaughtering weight 22-23 kg. Samples in freezer at -18 ??. Froze...

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...

Lamb meat quality of two Portuguese products was examined. The influences of slaughter weight, sex and breed on eating quality were evaluated. Data were obtained from 72 lambs of two different breeds with protected designation origin. In accord with the normal slaughter weight in the region three classes were considered: A: 9-14kg live weight; B: 14-19kg live weight and C: 19-24kg live weight. ...
