| Popis: | Pine shavings poultry litter from four growouts were analyzed for particle size distribution and chemical composition for untilled litter and litter that had been tilled three times following each growout. Little change in the particle size distribution was observed after the first growout for either treatment. The majority of the nutrient mass was associated with the larger size particles (those failing to pass a No. 50 screen) while the percent element analysis increased with the smaller size fractions for both treatments. Little change in nutrient content was observed between treatments, but the tilled litter had an increase in percent ash content and a decrease in percent crude fiber. No difference was observed in the crude protein percentage in the two treatments. |
