Probiotics and Herbs Combination in Commercial Feed Additives as Growth Promoter in Broiler Chicken

The prohibition on the use of Antibiotic Growth Promoter (AGP) causes the use of probiotics, herbs, enzymes and organic acids as an alternatives to AGP. This study aimed to determine the role of combination of probiotic and herbs in commercial feed additives on broiler performance.
Sixty day-old male broiler were divided into 3 groups where each group consisted of 20 chickens with 4 replication each group. Group I was given commercial feed, group II was given commercial feed + AGP and group III was given commercial feed + combination of probiotics, herbs, enzymes and
organic acids. All chickens were kept for 5 weeks. Body weight gain (BWG), body weight (BW) and Feed Convertion Ratio (FCR) were calculated every week. Carcass percentage was calculated at week 5. The results obtained from BWG and BW on group III at weeks 4 and 5 weeks were higher and significant difference (P˂0.05) compared to groups I and
II. The percentage of carcasses between groups did not have a significant difference (P˃0.05). FCR values in group III from week 1 to weeks 5 were lower than groups I and II. The use of combination of probiotics, herbs, enzymes and organic acids has proven to have a good role on broiler
performance so that it can replace AGP as a feed additive on broiler.
