Evaluation of hays produced with Andropogon Gayanus at different ages using in situ degradability technique
In this study were evaluated Andropogon gayanus hays produced at different ages of growth (56, 84 and 112 days) to assay in situ dry matter (DM), organic matter (OM), crude protein (CP), and fiber fractions degradability. The statistical design was randomized blocks with split plots. The ages of growth were parcels and degradation time (0, 3, 6, 12, 24, 48 and 96 hours) were subparcels with five repetition by treatment (blocks). The different ages showed the same degradation kinetic behavior. A. gayanus hays produced with plant between 56 days are different from the 84 and 112 days of growth and had higher degradation for DM,OM,CP, NDF and ADF. The observed results indicated that the best A. gayanus hays are obtained from plants cut in between 56 days.
