Interpretive Summary:

Technical Abstract: Different sources and levels of condensed tannins were mixed with (M) or covered (C) broiler litter and embedded in a deep-stack for 3 or 9 wk. Substrates were vegetable extract ((VE) quebracho powder; Tannin Corp., Peabody, MA), peanut skins (PS), bird-resistant sorghum grain (BS), and sorghum grain (S), with condensed tannin concentration of 68.4, 25.6, .6, and 0%, respectively. Substrate levels were 0, .04, .09, .17, .35, 1.3, 2.6, 5.2, and 10.3% VE; 0, 3.6, 7.1, 14.2, and 28.4% PS; and 0, 5, 10, 20, and 40% BS and S. Condensed tannin recovery for VE (120, 113, 105, 98, 63, 27, 18, 1, 2, and 10% for M, and 125, 118, 107, 84, 59, 37, 23, 20, and 23% for C at 3 wk (SE 3.3); 87, 74, 66, 61, 44, 22, 16, 9, and 11% at 9 wk (SE 3.3) with 0, .04, .09, .17, .35, 1.3, 2.6, 5.1, and 10.3% VE, respectively), PS (139, 29, 18, 14, and 20% for M, and 126, 37, 27, 25, and 46% for C at 3 wk (SE 4.9); 52, 21, 12, 9, and 6% for M, and 91, 23, 1 4, 10, and 17% for C at 9 wk (SE 4.9) with 0, 3.6, 7.1, 14.2, and 28.4% PS respectively), and BS (135, 99, 109, 75, and 50% at 3 wk (SE 9.8); 97, 88, 88, 68, and 48% at 9 wk (SE 3.9) with 0, 5, 10, 20, and 40% BS, respectively) was less for 9 vs 3 wk and decreased with increasing substrate. Actual minus predicted NH3-N for VE, PS, and BS increased with increasing substrate level (-1.6, -1.3, .5, 1.0, 2.3, 2.7, 2.9, 1.9, and 2.7% (SE .51) with 0, .04, .09, .17, .35, 1.3, 2.6, 5.1, and 10.3% VE, respectively; 1.7, 3.0, 3.1, 3.4, and 5.0% (SE .52) with 0, 3.6, 7.1, 14.2, and 28.4% PS, respectively; 2.1, 2.4, 1.9, 2.4, and 3.9% with 0, 5, 1 20, and 40% BS, respectively). In summary, mixing with broiler litter befo deep-stacking decreased condensed tannin concentration.
