Study In Vitro: Kombinasi Herbal dan Probiotik sebagai Alternatif Antibiotic Growth Promoter

Antibiotic growth promoters (AGP) are widely used in animal feed for feed efficiency, stimulate growth, productivity and minimize mortality by preventing infection, but now its use has been officially banned by the government. As a result of the ban, many farmers or animal feed producer seek solutions in various ways such as the addition of herbs, probiotics, and a combination of both, but there are still few reports on the role of herbs, probiotics and a combination of both for alternative substitutes for AGP. This study aims to determine the role of herbs in the growth of probiotics. Herbs used ginger, turmeric, galingale, wild ginger, and temuireng, while the probiotics used are Bifidobacterium longum, B. bifidum, Bacillus sp., and Saccharomyces cereviciae. The benefits of herbs in supporting probiotics were tested using the disc diffusion method. Chloramphenicol disc ware used as control positive. Observation and measurement of the growth zone of probiotics were carried out after incubation. The results of this study prove that herbs do not inhibit the growth of probiotics. Herbal content can be a prebiotic candidate that can support the growth of probiotics. The combination of herbal-probiotics can potentially be an AGP substitute in animal feed.
