The experiment investigated the effects of Andrographis paniculata and Zingiber cassumunar
mixture (Mu-Plus®) on productive performance and carcass quality of broiler chickens. A total of 480 oneday-old chicks assigned to five dietary treatments with four replications of 24 chicks each. The basal
experimental diet supplemented Mu-Plus® at 0 (T1), 0.05 (T2), 0.10 (T3), 0.15 (T4) and 0.20% diet (T5).
Body weight gain, feed intake, and productive index had improved higher than the control group in broilers
fed 0.05 % diet group. Survival rate was significant (P0.05) by level of Mu-Plus®. However, Mu-Plus® 0.05 % diet fed broilers had shown the
higher in dressing percentage and total edible meat of broilers with lower abdominal fat and higher return on
investment (ROI).
