Bone Meal
a mineral additive in feed for farm animals made by processing the bones from slaughtered animals. It is made by grinding bones that are defatted by organic solvents and deglutinated by steam. Bone meal is rich in minerals, particularly calcium (245 g in 1 kg of feed) and phosphorus (118 g). For cattle, 40–100 g of bone meal are added to the ration, and for small animals, 8–20 g. Bone meal constitutes up to 1 percent of the weight of mixed feeds.
