Influence of different selenium sources on performance, blood and meat selenium content of fattening lambs
An investigation was conducted to evaluate the bioavailability of different Se sources on fattening lambs. Forty-eight lambs, divided in 3 groups, were ad libitum fed the same diet without Se addition (control, C), or with a supply of 0.03% sodium selenite (IS) or 0.03% of organic selenium (OS; Sel-...

| Summary: | An investigation was conducted to evaluate the bioavailability of different Se sources on fattening lambs. Forty-eight lambs, divided in 3 groups, were ad libitum fed the same diet without Se addition (control, C), or with a supply of 0.03% sodium selenite (IS) or 0.03% of organic selenium (OS; Sel-PlexTM). Growth performances were not affected by treatment. With respect to C, OS significantly increased Se content of blood (P<0.01), liver (P<0.01) and GSH-Px enzyme activity (P<0.01). OS also significantly increased blood (P<0.01) and liver (P<0.05) Se content with respect to IS. It was concluded that Se in organic form had a better bioavailability compared to the inorganic form. |
