Productive performances of Maremmana young bulls reared following organic rules (Reg. CE 2092/91 and Reg. CE 1804/99) were studied. Fourteen calves reared on pasture, supplemented with hay and concentrates of organic origin, were slaughtered at 19 and 23 months of age. Growth and somatic development were investigated.

Abstract
Productive performances of Maremmana young bulls reared following organic rules (Reg. CE 2092/91 and Reg. CE 1804/99) were studied. Fourteen calves reared on pasture, supplemented with hay and concentrates of organic origin, were slaughtered at 19 and 23 months of age. Growth and somatic development were investigated. Dressing percentage was calculated at slaughter. Chilled carcasses were evaluated according UE grid. Physical-chemical characteristics were determined on Longissimus thoracis (LT) and Caput longum triceps brachii (TB) muscles. Growth rate showed linear increase whereas dressing percentage (on average 52.11%) and carcass quality (conformation: R+; adiposity 2+ of UE grid) didn’t show significant difference between slaughter ages. Meat from animals of 23 months of age showed higher lightness, yellowish index, tinta and drip loss. TB raw muscle showed higher shear force and resulted with higher moisture, ether extract and ashes contents.
