Dominguez, S., J. Menkel, A. Fairbrother, B. Williams, AND R. Tanner. EFFECT OF 2,4-DINITROPHENOL ON THE METABOLIC RATE OF BOBWHITE QUAIL. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/J-94/084 (NTIS PB94144722).
Description:
Bobwhite quail were exposed to 2,4-dinitrophenol (DNP) in a respirometer designed to continuously monitor exchange of O2 and C02, from which metabolic rates (MR) were estimated. fter 14-16 days of acclimation to the system (temperature 22 degrees C, light cycle 8L:14D), hens received feed amended with 0, 625 ppm, or 1250 ppm DNP ad libitum for eight days, followed by 2-5 days of 0 ppm feed. he 625 ppm treatment produced dark period MR 31-41% higher than corresponding control values, and light period MR 23-32% higher than controls. he 1250 ppm treatment produced dark period MR 48-77% higher than control values, and light period MR 41-67% higher than control. ver the eight days of testing, the 625 ppm treatment hens expended 32V more energy than the control hens and hens consuming 1250 ppm feed expended 60% more energy than control hens and lost most of their body fat. n general, the risk of being unable to meet energy demands for survival or reproduction would probably be substantially increased by the observed elevation in MR.
