What is Meat and Bone Meal?

Meat and Bone Meal is a product made by cooking, defatting, sterilizing, grinding, and sifting by-products of bits of dead animals from the slaughterhouse that are not suitable for human consumption.

It is used in many animal feeds including dog, cat and chicken feeds to improve amino acid profiles of the feed. Meat and Bone Meal usually contains 48-52% protein, 33-35% ash, 8-12% fat and 4-7% water. 

Most parts of the world including Australia do not allow feeding Meat and Bone Meal feed to Ruminant animals to avoid diseases such as Mad Cow Disease. This is why on some feed bags it will say "This product does (or does not) contain Restricted Animal Material", meaning it either does or does not contain Meat and Bone Meals.
