Abstract

A 33-day feeding trial was conducted to evaluate the effectiveness of probiotics in drinking water on broiler performance. In this experiment, 300 day-old straight-run broiler chicks were randomly assigned to three treatments following a completely randomized design (CRD). Each treatment was replicated ten times with ten broiler chicks per replicate. The birds in Treatment 1 were given commercial feeds with plain drinking water. Broiler chicks in Treatment 2 were fed also with commercial feeds with 1.25g/L anti-biotics in drinking water for 14 days. The birds in Treatment 3 were fed commercial feeds with 1ml/L probiotics in drinking water throughout the feeding trial. Results revealed that final body weight, body weight gain, feed consumption, water consumption, dressing percentage and percent livability were not significantly different (P>0.05) among treatments. However, probiotics in drinking water significantly improved the overall feed efficiency of broilers.
