토종닭 실용계의 생산성, 도체율 및 육질특성 비교

Abstract

This study was conducted to compare performance, carcass yield, and meat quality of 4 Korean indigenous commercial chickens (Hanhyup 3: G, Sorae 1: V, Woorimatdak 1: S, Woorimatdak 2: W). A total of 384 chickens were divided into 4 treatments with 4 Korean indigenous commercial chickens, 6 repetitions per treatment, and 16 birds per treatment (♀ 8 birds, ♂ 8 birds). For 12 weeks, body weight was significantly higher in G and V breeds than S and W breeds (<i>P</i>&lt;0.01), but body weight gain lower in S breed (<i>P</i>&lt;0.05). Feed conversion ratio was significantly higher in W breed at 8~10 wk of age (<i>P</i>&lt;0.05). There was no significant difference on livability among four treatments. Carcass yield and fresh meat ratio were highest in V breed at 12 wk of age (<i>P</i>&lt;0.05). On breast meat, shear force was lower in G breed (<i>P</i>&lt;0.05), and higher in male than in female (<i>P</i>&lt;0.05). Lightness (L^*) of breast meat was higher in female except V breed, and redness (a^*) was significantly higher in breed G (<i>P</i>&lt;0.05). Yellowness (b^*) of breast meat was higher in G and V breeds, and higher in male than in female except breed G. In conclusion, G and V breeds showed superior performance, and S and W breeds showed superior meat quality.
