The growth in the broiler industry and the concomitant increase in the broiler litter generated out of these operations, coupled with increased environmental awareness, has resulted in increased interest by producers and scientists in uses for broiler litter.
Long-term land applications of broiler litter have resulted in a buildup of some nutrients in certain soils.
Research results indicate that annual application rates of up to 4 tons/acre of litter are acceptable, but should be accompanied by annual soil testing.
Broiler litter of adequate quality is acceptable as a livestock feed, provided the litter is properly processed prior to feeding.
When used as a livestock feed, the ash level in litter is of concern due to its negative effects on the nutritive value (total digestible nutrients, TDN) of litter diets containing relatively high ash levels.
Based on expected levels of performance, broiler litter-based diets require varying levels of grain to meet the nutrient requirements of different classes of livestock.
Broiler litter can be used as both fertilizer and livestock feed, and the combining of broiler production with a commercial beef operation represents an attractive integration of two enterprises.
