Furthermore, Roland
(1988) attributed an additional 6.1% loss to uncollectable
eggs, such as those that fall through the cages into the
manure, which is estimated to cost $211.6 million per
year. In our experiment, the occurrence of cracked eggs
was more than 2.5 times greater from hens supplemented
with SY compared with those supplemented with SS.
Our results, however, are not consistent with the published
data. Siske et al. (2000) reported increased eggshell
strength when organic forms of Mn, Se, and Zn were
substituted into the diet for one-half of the inorganic
forms of these minerals
