摘要:

The energy metabolism was measured by means of indirect calorimetry in growing bulls with mean live weights of 290–420 kg and in wethers with mean live weights of 40–60 kg. The animals were fed 12 (bulls) and 8 rations (wethers) with high variation in the nutrients composition and with a range of energy metabolizability (q) between 0.74 and 0.47 on 3 steps of nutrition level (deposition, maintenance, underfeeding) as a rule.
