As shown in Figure 5 mold counts tend to be greatest in the first flock with WOwhile LP and YP values were similar. Placing the bedding materials in storage (Figure6) and treating with a mold inhibitor (Figure 7) had no apparent influence on moldpopulations. As reported in the literature, mold populations decrease significantly once aflock of birds have been grown on the bedding material.Log(#/g)8.28.187.97.87.77.67.57.48.27.97.7LP WO YPFlock 1Figure 5.
