- Abstract
AIM: to describe the methodology of calculating of Clarcs of energy distribution/protein transformation along the trophic chain “fodder – carcass meat” (in the case – “fodder-meat from M. longissimus dorsi”). METHODS: Experiment for fattening of 21 pigs (Danube white breed) from 30 to 110 kg live weight in 2 phases (30–60 and 60–110 kg). Controlled: Total fodder consumption, total metabolizable energy and total crude protein consumption, total weight and chemical composition of Musculus longissimus dorsi in the end of experiment. RESULTS: Clarc of energy distribution – CED (MEfodder – GEmeat of M. longissimus dorsi) – 0.0014 (0.14%); Clarc of protein transformation – CPT (CPfodder – CPmeat of M. Longissimus dorsi) – 0.0038 (0.38%).
