Abstract

A eight-week trial was carried out to investigate the effects of various levels and type of organic selenium as
compared to inorganic selenium. Total of 81 layer hens (LSL) 35 weeks of age were used in a randomized
complete blocks with 9 treatments, 3 replications of 3 birds per experimental unit. Treatment diets included
control 0/3 mg/kg sodium selenite and selenium yeast, (250 mg/kg, 500 mg/kg). Qualitative characteristics of
storing eggs under different conditions (23- 7°C) for 14 days determined. Haugh unit of keeping eggs in room
(23-27°C) was significantly (P
