Biological Effects of Different Selenomethionine Forms and Levels on Breeder Hens and Their Offspring
Selenium (Se) is an essential trace element for mammals and birds,and can be categorized into two forms,inorganic sodium selenite (SS) and organic se.Compared with the SS,the organic Se possesses antioxidant properties,has high bioavailability and accumulates in tissues without causing toxicity (Wang et al.,1997). The majority of the Se in organic Se (i.e.Se-yeast) is selenomethionine (SM),a Se analog of methionine (Beilstein and Whanger,1986).Zhan et al.(2007) reported that the SM was more effective than sodium selenite,in depositing Se in tissues and enhancing the antioxidant status. As the SM has two different forms (i.e.,L-SM and DL-SM),very few studies have been preformed to investigate the biological efficiency of these two SM forms. The present study hypothesized that the DL-and L-SM exhibited different biological effects. Thus the objective was focused on the effect of dietary SM form and level on Se distribution and productive performance in hens.
