Abstract

The present study was carried out to study the effect of guar meal korma (GMK) as a feed ingredient and some feed additives on growth performance, egg production, digestibility coefficients of dietary feed nutrients and economic efficiency of egg production of Egyptian Silver Montazah (SM) local laying hens. A 4x3 factorial arrangement design was used in this experiment including four levels of GMK (0, 5, 10 and 15 %) and three sources of feed additives, 0, Avizyme 750 mg/kg diet and Probiotics 250 mg/kg diet. A total number of 288 laying hens and 36 cocks of SM local strain, 22 weeks old, were used in this experiment. All birds were randomly distributed into 12 treatment groups (24 hens and 3 cocks / each treatment). Each group was sub-divided into three replicates of 8 hens and one cock. Laying hens of each group were nearly of equal average body weight and similar average daily egg production. Results obtained at the end of the experiment ( 36 weeks of age) showed that average live body weight of layers was significantly (P
