Arid and semi-arid climatic conditions and lack of water resources in some countries have led to a decrease in the quantity and quality of some animal feed. To compensate for these deficiencies, proper utilization of livestock and agriculture by-products or residues as feed ingredients, for example, poultry bedding, has led to improved conditions for the production of livestock products. The four-section gastrointestinal tract of ruminants, and also the microbial digestion in their rumen, have enabled this livestock to consume and digest cheap waste products, which resulted in reducing feed costs in the rearing of these animals. Besides, it would be beneficial to maximize the use of agricultural residues in feeding these animals. The nutritional value of poultry bedding as a feed ingredient is mostly due to its high crude protein and mineral contents. Because of the high degradable crude protein content in the rumen, this by-product can be used as a potential supplement for low-protein feeds. Also, since protein is the most expensive component of animal feed, poultry bedding is a proper alternative to protein sources which reduces the overall feed costs.
