Fig. 3From: Epidemiological investigation and drug resistance of Eimeria species in Korean chicken farmsComparison of body weight gain in field sample-infected chickens. Five-day-old ROSS 308 female chickens were orally infected with 3 × 104 sporulated oocysts of 9 different field samples (A–I). Body weight gain (n = 20) was measured at 9 days after infection. * P < 0.05, ** P < 0.01, and ***P < 0.001 indicate significant differences compared to untreated and healthy group (NC). The results represent mean ± SE values. NC, negative control; PC, untreated and infected group as a positive control; A-I, farm samplesBack to article page
