Responses to organic and inorganic selenium in the performance and blood selenium content of growing pigs
Kaija Suomi | Timo Alaviuhkola
An experiment was carried out with 36 growing pigs in order to compare their responses to organic selenium and inorganic selenium. No significant differences were found in daily gain, feed/gain ratio or carcass quality of growing pigs fed with 0.1 mg inorganic Se or the same amount of Se bound in yeast. Neither were there significant differences in the content of Se in the liver and serum between these Se sources. The amount of 0.4 mg yeast selenium in the feed increased the Se level in the serum and liver significantly as compared to a lower level ofsupplementation (0.1 mg) (p
