Figure 1.

Comparison of the H, L, and H/L values in blood samples from 2 different broiler breeds (WRR and LS) and under different conditions (H-WRR or H-LS means broilers under heat stress). (a) Means the percentage of heterophil; (b) means the percentage of lymphocyte; (c) means the ratio of heterophil to lymphocyte. Significant differences exist in the values with lower case letters in the same cluster, of the same breed, at the same age (P < 0.05). Highly significant differences exist in the values with upper case letters (P < 0.01).
