Studies on the sodium, chlorine and iodine requirements of young pheasants and quail.

Previous studies from this laboratory have dealt with the protein, calcium, phosphorus, vitamin D, manganese, zinc, riboflavin, niacin and choline requirements of pheasants (Scott, et al., '54, '58a, '59) . The phosphorus requirements of young Bobwhite quail also have been reported (Scott, et al., '58b). Although many studies have been made on the effects of various levels of salt in rations for chickens, little has been reported on the sodium and chlorine requirements of this species, and nothing on either salt, sodium or chlorine requirements of young pheasants and quail. Since iodine is usually supplied to practical rations in the form of iodized salt, it was considered desirable to determine not only the sodium and chlorine requirements , but also to determine whether or not the amount of iodized salt needed to supply these requirements would also suptJly sufficient iodine for normal growth and thyroid development in young pheasants and quail . The results of these experiments are presented in this report.
