The experiment carried out assessed the efficiency of plant extracts as alternative antifungal and growth promoters in broiler diet. The experiment includes 330 broilers raised from 1 to 28 days of ages to study their influence on feed consumption, body weight gain and feed consumption. At the end of the experiment, 60 birds were sacrificed to assess organ morphometric. The broiler chickens were divided into 10 groups and 3 replicates with 10 chickens each. Diet 1: Control for feed A (CFA) contained no plant extracts, diet 2: Control for feed B(CFB) containing no plant extracts, diet 3: Low level of Aristolochia ringens (LARA) at 125gm/25kg of feed A, diet 4: High level of A. ringens (HARA) at 250gm/25kg of feed A, diet 5: Low level of Mistrascarpus scarber (LMSA) at 125gm/25kg of feed A, diet 6: High level of M. scarber (HMSA) at 250gm/25kg offered A, diet7: Low level of A. ringens (LARB) at 125gm/25kg of feed B, diet8: High level of A. ringens (HARB) at 250gm/25kg of feed B, diet 9: Low level of M. scarber (LMSB) at 125gm/25kg of feed, B diet 10: High level of M. scarber (HMSB) at 250gm/25kg of feed B. No significant changes in body weight gain were observed with the plant extracts compared to CFA or CFB at 28 days. No differences in feed efficiency were observed with any treatment. The result suggest that A.ringens and M. scarber have antifungal properties and since they caused no significant changes in body weight and also feed consumption compared to CFA and CFB. It warrants further study as a substitute for antibiotics in the diet.
