The use of a meat and bone meal as a protein source for pig rations.

The use of a’ meat and bone meal as the main protein source for pigs of 20 kg was investigated. It was compared in two feeding periods with soybean and fish meals alone or with mixtures of the two. The pigs, fed either the soybean or the fish meal or the meat and bone meal with either soybean or fish meal, had significantly heavier weight gains than the pigs fed a ration with meat and bone meal alone. Feed conversion results followed a similar pattern to liveweight results.
