Abstract

An experiment was conducted to study the effects of supplementation of EM ( effective microorganism ) in feed on laying performance and egg quality. A 2x3 Factorial in Completely Randomized Design with 4 replications, using the total numbers of 288 layers was utilized. In one factor, supplementation and non-supplementation of EM were applied. In the other factor, supplementation of calcium at levels of 3, 3.5 and 4% were used. Results of the study, over the 3 period, 28 days per period revealed that there were no significant effects of supplementation of EM on daily feed intake, body weight gain, mortality, egg mass, egg weight, albumin weight, yolk weight, egg shell weight, yolk color and haugh unit (P>0.05). But egg production (P<0.05), feed per 1 dozen egg and specific gravity were highly significant difference (P<0.01).
