Comparison of Telomere Length and Vitality among Korean Native Chicken Breeds

We compared the degrees of vitality 12 Korean native chicken breeds, such as Jaeraejong, Rhode Island Red (Rhode), White Leghorn, Cornish (Cornish), and Ogye breeds. The survival rate telomere length were measured vital markers. Telomere was analyzed via quantitative fluorescence in situ hybridization method using lymphocytes 466 chickens. found that decreased linearly with increasing chronological age all shortening rates (TSR) significantly different among breeds after 20 weeks (P<0.01). had longest lowest TSR, whereas shortest highest TSR. In terms 50-week-old chickens half 8-week-old There also a significant difference Both rates, while lowest. positive correlation between length, old showed higher than young age. Therefore, it is considered TSR more closely related to length. Based on dynamics concluded breed vitality, respectively.
