Day old broiler chickens will be obtained from a commercial hatchery and reared and fed low energy diets including strategies to increase the inclusion of distillers dried grains with solubles (DDG/S) in broiler diets. In addition, dietary amino acids will be investigated throughout the production cycle. Production efficiency and meat yield will be characterized. Studies on varying light intensities will be conducted in light controlled chambers. Blood samples will be obtained for analyses of selected blood gases, electrolytes, and indicators of stress as well as evaluation of immune stress. Also, neuropeptides associated with proopiomelanocortin release will be determined by obtaining brain samples from the thalamic region. Specific dissected areas will be extracted and component neuropeptides will be fractionated according to molecular size. Peptide identification will be performed by liquid chromatography and mass spectrometry.
