Effect of supplementing selenium yeast in diets of laying hens on egg selenium content.
Poult Sci. 2005 Dec; 84(12):1900-1.PS

Abstract

An 8-wk experiment was conducted using 90 Hy-Line W-98 hens (26 wk of age) to evaluate the use of organic Se from Se yeast as an Se source for laying hens. At 22 wk of age, the hens were placed on a low Se corn-soybean meal pretest diet for 4 wk. At the end of the pretest period, hens were placed on 1 of 3 experimental treatments; the low Se diet without supplementation (basal diet), basal diet with 0.3 ppm of Se added from sodium selenite, or basal diet with 0.3 ppm of Se added from Se yeast. Diets contained 0.11, 0.38, and 0.34 ppm Se for basal, basal plus sodium selenite, and basal plus Se yeast diets, respectively. The experimental diets were each fed to 10 replicate groups of 3 hens for 8 wk (26 to 34 wk of age). Selenium levels in eggs (mg/kg of whole egg) were analyzed at 0, 4, and 8 wk. Egg Se contents at 0 wk were similar among treatments. Eggs from hens fed the 2 Se-fortified diets had higher (P < 0.01) Se concentrations than did eggs from hens fed the low Se diet at 4 and 8 wk. The Se yeast diet also yielded levels of egg Se that were significantly higher (P < 0.01) than those from the sodium selenite diet at 4 and 8 wk. The Se yeast resulted in a 4.8-fold increase in egg Se concentration compared with a 2.8-fold increase for the sodium selenite diet over the unsupplemented diet at 8 wk (0.065, 0.182, and 0.311 ppm for the control, sodium selenite, and Se yeast diets, respectively). There were no differences in egg production, egg weight, feed intake, or mortality among treatments. Results of this study indicate that use of Se yeast in laying hens diets is very effective for increasing the Se content of eggs.
