Abstract

We compared the effects of dietary protein and energy deficiencies onnorthern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) reproduction and determined if nutritional deficiencies leadto reproductive failure in quail. Captive adult female quail were feddiets that varied in protein and energy content, at both ad libitum and restricted levels. Protein and energy deficiencies led to declines in body and ovary mass, and egg production, but did not affect egg mass of either species. Although body mass and reproduction of both species were affected by protein and energy deficiencies, scaled quail wereless affected. Dietary energy was more important to body mass stasis and reproduction than dietary protein in both quail. Low energy diets led to elevations in corticosterone and increased food consumption in both species. Neither species increased food consumption in response to low dietary protein. Our study supports the hypothesis that macronutrient deficiencies can lead to reproductive failures in northern bobwhite and scaled quail.
