The objective of this study was to determine effects of spent mushroom (Cordyceps militaris) substrate supplementation in broiler diet on productive performance and some blood variables. A total of one-hundred and eighty, one day-old mixed sex Ross 308 broilers were randomly divided into 4 groups with 3 replicates of 15 birds under Completely Randomized Design (CRD). The diets supplemented with a standard diet (control), control + 0.05% chlortetracycline, 0.10 and 0.20% of mushroom substrate, respectively. The broiler chickens were fed ad libitum diet and water. The results showed the productive performance and some blood variables were not significantly different among groups (P>0.05). The average daily gain (ADG) was 39.02, 45.38, 39.85 and 43.41 gram/bird/day, respectively. The feed conversion ratio (FCR) was 1.67, 1.42, 1.50 and 1.46, respectively. The basal feed supplemented with spent mushroom substrate at 0.10-0.20% had better FCR than the control group, and similar to the control + 0.05% chlortetracycline group. The spent mushroom substrate supplementation has increased benefits to broiler industry.
