돼지의 도체 및 육질특성에서 스테비아와 숯의 항생제 대체효과

This study was conducted to determine effect of dietary reduced antibiotics supplementation on carcass characteristics and meat quality of finishing pigs fed stevia and charcoal. A total of 180 pigs (LYD) were randomly allocated into 3 treatments with 3 replications. Dietary treatments were 1) T1 (control, basal diet, no stevia and charcoal addition, antibiotics both in early and late fattening periods), 2) T2 (basal diet, 0.3% stevia + 0.3% charcoal, antibiotics both in early and late fattening periods), 3) T3 (basal diet, 0.3% stevia + 0.3% charcoal, antibiotics in early fattening period only). At each marketing day, pigs were conventionally slaughtered, examined the carcass characteristics and loin (Longissimus) muscles were removed for the meat quality traits. In the carcass characteristics, T3 group showed higher incidence of A carcass grade compared to the other treatments. Backfat thickness was higher in T2 group compared to the others (p
