Effects of anabolic implants and ractopamine-HCl on muscle fiber morphometrics, collagen solubility, and tenderness of beef longissimus lumborum steaks.
The objective of this study was to examine the effects of growth-promoting technologies (GP) and postmortem aging on longissimus lumborum muscle fiber cross-sectional area (CSA), collagen solubility, and their relationship to meat tenderness. Two groups of black-hided crossbred feedlot heifers (group 1: = 33, initial BW 430 ± 7 kg; group 2: = 32, initial BW 466 ± 7 kg) were blocked by BW and as...
متن کاملMuscle and Lipid Biology and Biochemistry 132: AGING-INDUCED CHANGES IN SARCOPLASMIC PROTEOME OF THREE BEEF HINDQUARTER MUSCLES WITH DIFFERENTIAL COLOR STABILITY
specific variations in sarcoplasmic proteome influence beef color. Post-mortem aging is a common practice employed by beef industry for improving beef tenderness and palatability. However, the color attributes and sarcoplasmic proteome of beef muscles undergo changes during aging. The objective of this study was to examine the changes in the sarcoplasmic proteome profile of three differentially...
متن کاملPostmortem proteolysis in longissimus muscle from beef, lamb and pork carcasses.
Postmortem proteolysis in skeletal muscle and factors affecting this process were examined in pork, lamb and beef longissimus muscles (LM) to determine the cause of differences in meat tenderness among these species. Fat thickness differed among species in the following order: pork greater than beef greater than lamb. The following patterns were observed for rate of temperature and pH decline: ...
متن کاملFibre type characteristics and postmortem glycolysis of bison (Bison bison bison) Longissimus lumborum
Janz, J. A. M., Aalhus, J. L. and Price, M. A. 2002. Fibre type characteristics and postmortem glycolysis of bison (Bison bison bison) longissimus lumborum. Can. J. Anim. Sci. 82: 259–262. To augment the limited information base, muscle fibre and postmortem glycolytic data from bison longissimus lumborum were compiled. As expected, postmortem glycogen concentration and pH declined while lactate...
متن کاملEffects of ractopamine hydrochloride and zilpaterol hydrochloride supplementation on longissimus muscle shear force and sensory attributes of beef steers.
Effect of ractopamine hydrochloride (RH) and zilpaterol hydrochloride (ZH) on LM shear force and sensory attributes was determined using pens (n = 40) British × Continental crossbred steers randomly allocated to one of the following treatments: control; RH fed at 200 (RH 200) or 300 mg • steer(-1) • d(-1) (RH 300), or 400 mg • steer(-1) • d(-1) (RH 400) top-dressed for the final 30 d of feeding...
