German Origin

Histochemical characteristics of muscle were evaluated in 12 German Heath lambs (6 males and 6 females). The lambs were slaughtered at the age of 150 days and samples of musculus longissimus lumborum et thoracis and quadriceps femoris were collected and measurements of fibre cross sectional area (µm2), diameter (µm2), and perimeter (µm2) were performed. Subsequently the fibre type distribution (%) was calculated. The dataset was evaluated using SAS 9.3. Significantly higher (P < 0.05) cross sectional area, diameter, and perimeter attributes were observed in females compared to males. Significant differences (P < 0.05 to 0.01) were observed in fibre type distribution between musculus longissimus lumborum et thoracis and quadriceps femoris muscle. The presented study describes evaluation of morphological formation of skeletal muscle tissue performed on a sheep breed of German origin. The results may be useful for meat scientists or meat industry due to close connection of these characteristics to meat quality.

Fibre Type Distribution

The percutaneous muscle biopsy procedure is an invaluable tool for characterizing skeletal muscle and capillarization. Little is known about methodological or biological variation stemming from the technique in heterogeneous muscle. Five muscle biopsies were taken from the vastus lateralis of a group of young men (n = 29, 22 ± 1 years) over a 96-h period. We investigated the repeatability of fibre distribution, indices of muscle capillarization and perfusion, and myofibre characteristics. No differences between the biopsies were reported in myofibre type distribution, cross-sectional area (CSA), and perimeter. Capillary-to-fibre perimeter exchange index and individual capillary-fibre contacts were unchanged with respect to the location of the muscle biopsy and index of capillarization. The variability in the sampling distribution of fibre type specific muscle CSA increased when fewer than 150 muscle fibres were quantified. Variability in fibre type distribution increased when fewer than 150 muscle fibres were quantified. Myofibre characteristics and indices of capillarization are largely consistent throughout the vastus lateralis when assessed via the skeletal muscle biopsy technique. Novelty Markers of muscle capillarization and perfusion were unchanged across multiple sites of the human vastus lateralis. Myofibre characteristics such as muscle cross-sectional area, perimeter, and fibre type distribution were also unchanged. Variation of muscle CSA was higher when fewer than 150 muscle fibres were quantified.
