초록

This study was conducted to investigate the effects of dietary supplementation with Ptecticus tenebrifer powder on the mortality and meat quality of Korean native chickens. A total of 40,000 Korean native chickens (1 day old, Hanhyup No. 3) were allocated to two dietary treatments (20,000 chickens in each treatment), which were fed the following: basal diet (control) and 1% of Ptecticus tenebrifer powder (T1). Feeding trials were conducted for 12 weeks, and mortality was measured weekly. At the end of the experimental period, 16 chickens (8 chickens in each treatment) were selected and slaughtered to obtain breast meat. The items used to analyze meat quality were pH, TBARS, and meat color. The weekly mortality rate was decreased by around 2 to 3 times in the T1 treatment group compared with the control group. The pH, TBARS, L*, and b* values of Korean native chicken breast were not affected by Ptecticus tenebrifer powder supplementation (p>0.05); however, a* values showed statistical significance (p<0.05). In conclusion, the addition of 1% Ptecticus tenebrifer powder reduced mortality rate and demonstrated its potential in livestock environmental management.
