Experiments were conducted on chick broilers and hens to determine the metabolizable energy of citrus sludge. A determination of metabolizable energy values showed that the values decreased as the level of citrus sludge in the diet increased. A series of protein levels were fed to day-old chicks for a 3-week period in an attempt to assay the protein quality of citrus sludge. As the level of sludge in the diet increased, its utilization decreased with an almost toxic effect being observed at higher concentrations. Vitamin D3 and citrus sludge were fed to day-old chicks to determine if the minerals contained in the sludge could be causing the destruction of Vitamin D3 in the feed. Experiments were also conducted to evaluate the biological availability of phosphorus contained in the sludge. Citrus sludge was also examined as a source of pigmentation in egg yolks and in broilers.
