Ajit Singh ^[7] | Pranab Doley

Abstract: An experiment was conducted to determine the immunomodulator of broilers fed diets supplemented with a Tulsi (Ocimum sanctum) leaf powder. A total of 72 (Arbor-Acres) day old chicks were used in this study. Four levels of a Tulsi (Ocimum sanctum) leaf powder at the rate of 0.00 %, 0.25 %, 0.50 %, and 1 % were incorporated into the basal diet for six weeks. Feeding period for all groups was lasted for 42 days. Birds were vaccinated with ND virus and serum was assessed for humoral immune response (HI). Cell mediated immune response (CMI) was assessed as increase in IDF thickness after and before PHA-P injection. Supplementation of Tulsi at either dose showed improved HI and CMI responses. Increasing the supplementation level of herbal Tulsi (from 0.25 to 1 %) improvement HI and MI. The humoral immune response (HI) and Cell mediated immune response (CMI) significantly higher in 1 % Tulsi leaf powder group (T4) as compared control (T1) in a column (4th week & 6th week). The study indicated that Tulsi at 1 % could be used as natural supplement to improve immune response in broiler chicken.
