Hypothesis
This study aims to determine the total number of myofibers in the skeletal muscles of slow- and fast-growing broilers and analyze their meat quality.
Conclusion
The study found that fast-growing Arbor Acres broilers have significantly higher total numbers of myofibers and different amino acid profiles compared to slow-growing Wenchang chickens.
Supporting Evidence
- The total number of myofibers in the pectoralis major muscle of Arbor Acres males was significantly higher than that of Wenchang males.
- Essential amino acids were found to be significantly higher in Wenchang chickens compared to Arbor Acres.
- The shear force of the pectoralis major muscle was higher in Arbor Acres than in Wenchang chickens.
Takeaway
This study looked at two types of chickens to see how many muscle fibers they have and how that affects the quality of their meat.
Methodology
The study used a deep learning tool called MyoV to quantify the total number of myofibers in the pectoralis major muscle and other muscles of Arbor Acres and Wenchang chickens.
Limitations
The study focused only on two breeds of chickens and may not be generalizable to other breeds.
Participant Demographics
The study involved 80 male and 80 female chicks from each breed, raised under controlled conditions.
