JIMENEZ A., Ronald et al. Effects of particle size and type of ammoniation-preservation on the digestibility and intake of corn crop residues in sheep. Rev. investig. vet. Perú [online]. 2010, vol.21, n.1, pp.19-25. ISSN 1609-9117.

The effect of particle size (PS) and type of ammoniation-preservation (AP) on the digestibility and intake of corn crop residues in sheep was evaluated. Four sheep were used in a 4 x 4 factorial arrangement: PS (1, 2, 3, and 4 cm) and AP. There was no effect of PS, but ammoniated silage treatments (AS, SC, SI) significantly (p<0.01) improved the digestibility and intake of the corn crop residue. AS and SI performed better in protein and fiber digestibility. It was concluded that the 2 cm- AS combination was considered the most appropriate from an economic, practical and technical viewpoint.

Keywords : sheep; particle size; corn crop residues; ammoniated; digestibility; intake.
