Abstract

Abstract Background Effective Microorganisms is the mixed cell culture composed of photosynthetic bacteria, actinomyces, yeast, lactobacillus and fungi which improves growth rate, feed efficiency, egg production and increases the health status of poultry. The experiment was conducted to evaluate the economic efficiency of effective microorganism’s supplementation to Bovans Brown laying hens. Results The result revealed that layers fed in T4 (124.07g) was significantly higher (P < 0.05) than T1 (119.67g), T2 (122.36g) and T3 (122.37g). The total egg production during the experimental period (week 20 to week 67) was 241,242,249 and 268 for T1, T2, T3 and T4, respectively. The highest (P < 0.05) feed conversion ratio was observed in T4 (2.23). The total feed cost was T1 > T2 > T3 > T4. The highest net revenue was obtained from T4 and the lowest was T1 and T2. The economic efficiency was ranged from 0.66 to 0.90 and the feed cost ratio was ranged from 1.66 to 1.90 ETB. Conclusion Therefore, from this study it can be concluded that supplementation of EM with drinking water and in feed (T4) had the best production performance indices among the treatment groups.
