Japanese quail is one of the popular livestock for being used as animal protein by the society. Farmers use the antibiotics as a feed additive as a growth promoter in a small amount which can improve feed efficiency. The overuse of antibiotics may be harmful, which can cause resistance to pathogenic microorganisms and residues in meat and eggs. Probiotics are non-pathogenic microorganisms which provide health benefits Rahayu and Purwandhani (2007). With this view, this study was carried out to assess the effects of supplementation of probiotics (Probeads EC®) on growth traits in Japanese quail. A total of 240 Nandanam quail III day old chicks were weighed individually, then randomly assigned to two treatment groups of 120 chicks each. There were 24 chicks per replicate and five replicate per treatment group. A total of 96 Probeads EC®/replicate/days were given to the treatment groups, and empty beads (without probiotics) were given to the control groups, up to 5 weeks. Weekly body we

The above study concluded that, supplementation of Probeads EC®had improved the body weight and body weight gain in Nandanam quail III. Similarly, supplementation of probeads on Nandanam quail III showed less feed consumption, better feed efficiency and livability than control group.
