MOKSNES, KNUT and GUNNAR NORHEIM: Selenium concen trations in tissues and eggs of growing and laying chickens fed sodium selenite at different levels. Acta vet. scand. 1982, 23, 368-379. -Growing and laying chickens were fed graded levels of selenium in the form of sodium selenite. One day old Norwegian bred broiler chickens and 20 weeks old Norwegian bred White Leghorn chickens were divided into 5 groups each and fed a basal diet supplemented with 0, 0.1, 1.0, 3.0 or 6.0 !1g Se/g for 6 and 31
more » ... Se/g for 6 and 31 weeks, respectively. At the end of the experiments significantly higher concentrations of selenium were found in the groups fed 1.0, 3.0 and 6.0 !1g Se / g diet compared to the control group. Correspondingly higher concentrations of selenium were found in egg samples. The increase in e'gg yolk selenium was much higher than in egg white. Significant correlations were found between the amounts of selenium added to the ration and the selenium concentrations in liver, kidney, breast muscle, egg white, yolk and homogenized egg. There were no differences in body weight gain and egg production between the groups. A possible positive contribution to animal and human health of selen ium supplementation of animals' diet above the required level is discussed, dietary selenium; tissue; egg; selenium concent rat ion s; g row i n g chi c ken s ; I a yin g chi c ken s.
