Resumo: | The objective of this was to evaluate the effect of chemical treatments with urea (3 or 5% DM) and anhydrous ammonia (3% DM) applied to the post-harvest hay residues of Brachiaria brizantha cv. Marandu that contained different moisture contents (15, 25 or 30%). A randomized block design was used with eight treatments and four replications (defined as the bale layers within the hay stacks). The hay treated with 3% anhydrous ammonia and 15% moisture content reduced the levels of neutral detergent fiber (NDF) from 84.3 to 79.1% and increased the in vitro digestibility of the dry matter (DM) from 37.3 to 55.5% compared to the control group. The variation in the moisture content did not significantly alter the action of ammonia, with mean values of 77.6% NDF and 57.3% in vitro digestibility of DM. The hay with 5% urea reduces the NDF content from 84.3 to 79.6% compared to the untreated hay, so the hay moisture content has to be increased to 30% to achieve a greater effect on the DM digestibility, which subsequently increases by 12 percentage units. |
