The aim of this research was to study the myofibrillar evolution of different types of muscular fibers in longissimus dorsi muscle of Chianina steers and bulls reared in feed-lot and slaughtered at 13, 20 and 26 months still showed an high percentage of splitting myofibrils. At 20 months this percentage was reduced and it remained constant up to 26 months; observing the trend of the slitting myofibrils percentage as a function of age, we noted tha at 13 months castrated animals showed a significant difference in the percentage of myofibrillar division in comparison of that stated for bulls.

Abstract
The aim of this research was to study the myofibrillar evolution of different types of muscular fibers in longissimus dorsi muscle of Chianina steers and bulls reared in feed-lot and slaughtered at 13, 20 and 26 months still showed an high percentage of splitting myofibrils. At 20 months this percentage was reduced and it remained constant up to 26 months; observing the trend of the slitting myofibrils percentage as a function of age, we noted tha at 13 months castrated animals showed a significant difference in the percentage of myofibrillar division in comparison of that stated for bulls.File in questo prodotto:
