Summary and Implications
A nutritional approach to estimating manure excretions allows producers to evaluate the impact of dietary strategies in their operation; considering nutrients that will be land applied as well as those that may volatilize during storage. A national effort is nearing completion that will take a nutritional or mass-balance approach to estimating excretions by revising the current table values of manure composition and characteristics.
