Abstract/Context: The dataset collects the results of four large scale experiments conducted to evaluate the energy sparing effects of supplemental protease by measuring nutrient digestibility, total tract metabolisability, energy partitioning (indirect calorimetry), and live performance of broilers.
Experiment 1 evaluated the effects of supplemental protease and diet type (maize- or wheat -based) on jejunal and ileal digestibility and total tract metabolisability of nitrogen, starch, and energy in broilers from 6 to 31 d of age.
Experiment 2 consisted of 2 trials which evaluated the effects of supplemental protease and cereal grain source (maize- or wheat-based) on nutrient digestibility (nitrogen, starch, and digestible energy) and live performance (trial 1), and nutrient digestibility (nitrogen, starch, and digestible energy) and energy partitioning (indirect calorimetry) (trial 2) of broiler chicks fed maize-based diets with reduced amino acid concentrations.
Experiment 3 explored the effects of varying AME concentrations (low-, moderate-, or high-AME) and protease supplementation (without or with) on broiler growth performance and jejunal and ileal digestibility (nitrogen, starch, and digestible energy) of broilers during a 5-week production period.
Experiment 4 assessed the effects of supplemental protease (without or with) and dAA concentrations (standard or reduced) on energy partitioning (indirect calorimetry) and live performance of broilers.
Data are organized based on experimental number. Within each folder consists of subfolders, which contain animal ethics, diets, protocol, and measured results (i.e. nutrient digestibility, energy partitioning, live performance).
