However, this assessment system may not directly translate to the US duck industry. One important management practice that is different between the United Kingdom and the United States is flooring type; in Europe most commercial facilities have solid floors with chopped straw bedding. The UK requirement for open trough waters results in considerable straw usage to account for the extra water waste. In the United States, duck barns use predominantly water nipple lines and the prevalent floor types are solid floors with wood shaving litter, raised wire/plastic floors, or a combination of the two.
