| Abstract: | 1. Broilers were fed on wheat‐casein or wheat‐soyabean meal diets and the excreta collected after 12 and 24 h. Samples of excreta were freeze dried or dried in a force draught oven at 60 or 80 °C. 2. Drying procedure and collection time significantly influenced the determined energy and nitrogen concentrations of the excreta. 3. Drying excreta in an oven at 60 °G proved at least as effective as freeze drying for the majority of amino acids. |
