In past years, a substantial amount of research has centered on the levels of certain blood chemical constituents in birds, particularly in chickens and pigeons. However, little has been recorded concerning the blood chemical constituents of the mallard duck, Anas platyrhynshos. Likewise, the effects of hormones on its blood chemistry, in conjunction with its reproductive system, have been almost totally unexplored. Therefore, this study, conducted from October 14, 1965, to March 3, 1966, had as its purpose the determination of normal quantitative levels of certain blood chemical constituents (the electrolytes--calcium, sodium, potassium; the proteins--albumin and globulin; and lipids) and the measurement of the effects of estrogenic and gonadotrophic hormones on these constituents; and hence, on the reproductive system of the non-laying female mallard. Financial support for the work was supplied through a grant from The United States Department of Interior, Bureau of Sport Fisheries and Wildlife Service, contract number 14-16-0008-728.
