Therefore, this study was designed to characterize biochemically the contractile and metabolic type of goatling muscles through of myofibrillar ATPase and lactate dehydrogenase (LDH) activities respectively.
Myofibrillar ATPase activity is correlated with contraction speed because it is responsible for hydrolyzing ATP during muscle contraction.
Myofibrillar ATPase and lactate dehydrogenase (LDH) activitieswere determined at 1 hour of ageing time (because these enzymes exhibit activity only in the early hours post mortem),pH values and decline rate were measured every hour, from 1 hour up to 24 hours of ageing time, cathepsins activities were determined at 1, 10, 24 hours 6 and 8 days; after reaching the appropriate ageing times, samples for cathepsins activities were stored at -80C until analysis (within two weeks), myofibrillar toughness was performed only SM and ST muscles (because muscle L did not reach the thickness of 1cm required to make this determination) at 1, 6 and 8 days.
05) the ash content, myofibrillar ATPase activity and emulsification capacity of the pectoral major muscle in mature capons (26-week-old) compared to the Sham in trial 2.
Early caponization however, did not influence on the moisture, crude protein, crude fat contents, pH value, emulsification capacity and myofibrillar ATPase activity (p>0.
