Rapid determination of metabolisable energy of foods using cockerels

摘要: 1. Adult cockerels were trained to consume their daily food allowance of about 100 g in 1 h. Excreta collected for the next 24 h and metabolisable energy (ME) content diet was determined. 2. Two different diets used study effects ME on adaptation diet. Repeatable estimates obtained without a period adaptation. 3. No difference found when test fed adult h, or continuously excreta over 5 d. The conventional total collection method determining using groups growing chickens yielded similar results. 4. between 48, 48 72 post‐feeding constant values following feeding two diets, indicating that all from 1‐h voided during 5. is precise results can be reported 36 after receipt sample.
