Nutritive and Biological Value of Liver and Blood of Various Slaughtered Animals

Offal, such as liver, heart, tongue, kidneys, blood, skin, bone, etc., represents an essential source of protein, vitamin and mineral elements. The present study is an attempt at determining the amino acid composition of horse and beef liver and blood. In general, horse liver was to be a good source of protein (25.06%) compared with beef liver (17.4%). The moisture (74.9%) and fat (3.8) contents were significantly higher (p<0.05) in beef liver, while the ash content of the horse liver was 1.42% compared to 1.30% in beef liver. Total essential amino acid content was higher in beef liver (40.63%) than in horse liver (37.31%).
