Interpretive Summary:

Technical Abstract: Broiler litter was deep-stacked without or with a plastic cover (open, O; cover, C), with 0, 2.8, or 5.7% urea, and with 0, 5, 10, or 20% (dry matter (DM) bermudagrass hay (B), ground corn (G), or molasses (M) to determine changes in nutrient composition and recovery. Litter and mixtures were placed in duplicate dacron bags in the center of deep-stacks for 9 weeks (wk). Covering increased neutral detergent fiber (NDF) recovery with 0% urea (68, 60, and 57% for O, and 74, 61, and 58% for C with 0, 2.8, and 5.7% urea, respectively; SE 1.0) and decreased recovery of neutral detergent soluble organic matter (NDSOM) (e.g., B: 126 vs 130%; SE 1.2). Urea decreased NDF recovery and increased recovery of NDSOM (122, 130, and 132% for B (SE 1.4); 133, 138, and 139% for G (SE 1.3); 124, 127, and 129% for M with 0, 2.8, and 5.7% urea, respectively (SE .9)). Urea addition and covering did not greatly change ruminal in situ (48 hour) DM disappearance (e.g., B-O: 87, 90, and 91% with 0, 2.8, and 5.7% urea, respectively (SE .7); B-C: 91, 89, 88, and 84% for 0% urea, 91, 90, 87, and 89% for 2.8% urea, and 92, 92, 91, and 88% for 5.7% urea with 0, 5, 10, and 20% B, respectively (SE .4). In conclusion, urea addition and covering deep-stacked broiler litter altered chemical composition but did not appreciably affect in situ DM disappearance.
