Basophils by releasing histamine can control and are responsible for allergy and antigens in the body (Vleck
et al., 2000). In chickens, high basophil level in blood indicates the birds are under abnormal environmental
condition like heat stress or facing pathogenic infection (Tamzil et al., 2014), while lower level indicated
that the birds are in healthier conditions (Maxwell et al., 1992). In our trial, basophil count was lower in
birds fed OligoPKE, especially those fed 1% OligoPKE at 21 DOA, suggesting that OligoPKE supplementation
enhances immune system in the broilers. Dietary OligoPKE did not affect lymphocyte, monocyte and
eosinophil concentrations in birds at 21 DOA. Conversely,OligoPKE supplementation did not affect all
the hematological parameters measured in birds at 35 DOA. The above result seems to suggest that supplementation
of OligoPKE was more effective in broiler chickens during their younger age when their immune
system was not fully developed (Beal et al., 2004).
