Book Description
Two hundred and seventy day-old female chicks were randomly distributed to six treatments each in Phases II and III. Three replications were maintained in all phases of the study. Varying levels of dried poultry waste (DPW) was incorporated in the diets of chicks, growing pullets and layers and compared to similar levels of rico bran in the diets. Feed intake was not affected by feeding chiks with the diet containing 5 per cent DPW. Levels of 5, 10 and 15 per cent DPW in the diets did not affect gain in body weight and mortality at 8 weeks. Feed efficiency poorer at 10 and 15 per cent. The 15 and 20 per cent levels of DPW in the diet of growing pullets did not influence the amount of feed intake. Gain in body weight and mortality of growing pullets were not affected by feeding diets with 10, 15 and 20 per cent DPW. Feed efficiecny was significantly poorer at 20 per cent DPW however, but no significant differences were observed at 10 and 15 per cent levels of DPW. Layers fed diets with 15, 20 and 25 per cent levels of DPW had better egg production, produced heavier eggs, had better feed conversion efficiency, and had lower mortality rates as compared to those fed the rice bran diets. Egg quality was not influenced by feeding diets with varning levels of DPW as measured by Haugh unit scores. Egg color was more intense at 20 and 25 per cent levels of DPW. Feed consumption was significantly influenced by feeding diets with varying levels of DPW.

Book Description
In developed market economies with intensive animal production systems, such as The Netherlands, many new feedstuffs have been introduced as part of the diets of ruminant and monogastric animals. These new feedstuffs are often by-products of human food processing. It is important that these by-products and also the by-products from wastes are properly evaluated with regard to the possibilities of incor porating them into livestock diets. Research on the subject of feed from waste, its processing and its use in the nutrition of poultry has increased considerably during the last decade. The Department of Animal Nutrition of Wageningen Agricul tural University (WAU), Wageningen, The Netherlands, in close co operation with the Poultry Feeding and the Processing Industry, has been active in this field. In order to update research and to expedite further work in this field, a comprehensive review of the literature on the subject of feed from waste was made. Such a study would not only bring the industry up to date on the subject but could also indicate specific topics which may be of great value for developing market economies. Poultry scientists and technologists suggested that a review would fill a need as a reference and textbook, not only for the industry but also for undergraduates and graduates of agricultural colleges and extension services all over the world.
