Chemical composition, in vitro digestibility, and storability of selected agro-industrial by-products: Alternative ruminant feed ingredients in Israel.

The global demand for animal-based products is rising in the face of dwindling feed resources, and yet a huge pool of agro-industrial by-products (AIBPs) are generated, underutilized, and improperly deposited to landfills leading to environmental pollution. Ruminants have a special microbiome that can bioprocess and convert human inedible fibrous material into meat and milk, which appears as a great opportunity to simultaneously reduce pollution while promoting food security. In this study, we collected 15 domestically produced AIBPs from various regions of Israel during both winter and summer seasons to examine their potential as ruminant feed alternatives.
