Meat and bone meal is the dried and rendered product from mammal tissues. It does not contain horn, hair, hide trimmings, manure, stomach contents, added blood meal or poultry by-product. The calcium content should not be more than 2.2 times the phosphorus content. A calcium content higher than this indicates additional calcium from a source other than bone.
The protein in meat and bone meal is degraded relatively slowly in rumen.
Meat bone meal can be fed as a protein source. It may be included in the grain mix at a rate of up to 5 percent or fed at up to 1 ½ pounds (0.68 kg) per cow per day. It is not very palatable and should be introduced into the ration gradually.
