| Abstract | ||
| This study was conducted at the Poultry Farm, Department of Animal Resources, College of Agriculture, University of Baghdad, during the period from 21 / 2 / 2013 to 7 / 9 / 2013. The aim of this experiment was to compare the effect of supplementation of organic and inorganic selenium to the diet on productive performance of laying hens. (147) females of Lohman Brown, (20) weeks old were used in this study. Females were reared during experimental period at the cages, and at 22 weeks old of age, birds were randomly distributed into 7 treatment groups with 3 replicates in each treatment group, so (7 females for replicates, 21 females for treatment). Control group T1 were fed on basal diet, and inorganic selenium (sodium selenite) were supplemented to treatments, T2, T3 and T4 with 0.3, 0.5 and 0.7 mg/kg feed respectively and organic selenium (sel-plex) were supplemented to treatments, T5, T6 and T7 with 0.3, 0.5 and 0.7 mg / kg feed respectively. Supplementation of organic selenium (sel-plex) and inorganic selenium (sodium selenite) was used from 22 weeks of age until the end of the experiment, at 39 weeks old. The results showed that there was high significant (p<0.01) improvement in productive traits included egg production ratio, egg mass, cumulative eggs number, egg weight and feed conversion coefficient in treatment groups that have added selenium, with superiority of the effect of supplementation of organic selenium compared with inorganic selenium in most of studied traits. | ||
