Description 
By-product of commercial processing of whales.
Processes 
Whales are processed only on a commercial scale. During the processing the whale meat is heated using steam and is broken down into a slurry releasing the oil, which is the primary product. The oil is then centrifuged off and the remaining material is divided into liquid and solid fractions. The solid material is dried, ground and marketed as whale meal. The liquid fraction can be concentrated and acidified and sold as whale solubles.
Nutritional aspects
Nutritional attributes 
Whale meal and whale solubles are good sources of crude protein and water soluble vitamins, including B-12. Whale meal has primarily been used as a supplemental source of protein for monogastric animals.
Potential constraints 
Mercury (Hg) has been shown to accumulate in whale meat, so care should be take to assure that Hg levels are within acceptable levels in the meal. The Hg content in the tissues was found to increase as the amount of whale meal of solubles increased in the diet of swine (3)(CAB 771460767) (Godfrey, 1977).
Pigs 
Whale meal replace meat and bone meal in a swine grower ration (20 to 85 kg) with no effect on feed conversion and gain observed (3)(CAB 771460767)(Godfrey, 1977). Replacing meat and bone meal with increasing amounts of whale solubles progressively decreased gain and feed conversion in growing swine (3)(CAB 771460767)(Godfrey, 1977).
Minks 
Replacement of 50 % of frozen pollack with whale meal did not reduce reproductive performance in minks, but did reduce pelt quality (2)(CAB 741417874) (Efimova, 1974).
