Use of antibiotics as feed additives has been prohibited because possibility of resistance. Alternatives that can maintain health and increase poultry production are needed. One of it is by providing probiotics and herbs. This research aims to analyze the effect of adding combination probiotics herbs as feed additives to resistance characteristics of digestive tract bacteria and performance of broiler chickens.
The material used in this research was 74 Lohman strain broiler chicken which were divided into two groups, with each group consisting of 37 chickens. The treatment group was given combination of herbs and probiotics in drinking water, while the control group was given no combination of herbs and probiotics. Chickens are kept for 35 days. Three cloacal swab samples were taken before treatment and three samples after treatment then an antibiotic sensitivity test was carried out using the Kirby Bauer method. Testing was carried out on the antibiotics ampicillin 10 ?g, ciprofloxacin 10 ?g, kanamycin 30 ?g, penicillin 10 ?g, streptomycin 10 ?g, and tetracycline 30 ?g. The resistance results obtained from zone of inhibition formed and compared with CLSI standard. The performances of broiler chickens are observed by measuring body weight gain and calculating feed conversion at the end of every week. Data on average feed consumption, body weight and FCR were analyzed and tested using the T-Independent method in the SPSS program.
Resistance test on samples before administration feed additives was 100% resistant to ampicillin, ciprofloxacin, kanamycin, penicillin, streptomycin and 33% resistant to tetracycline. The samples after administration was 100% resistant to all of the antibiotics tested. In the treatment group given a combination of herbs and probiotics, performance of broiler chickens includes feed consumption and body weight gain increased and the FCR value was lower than the control group. The results of this research showed that giving a combination of herbs and probiotics in drinking water had effect on the resistance characteristics of good bacteria in the digestive tract and was able to improves the performance of broiler chickens, but not significantly. The best performance was shown by the treatment group in the fifth week with average body weight of 2,5 kg and FCR value of 1,38.
