Abstract

The objective of this research was to select elephantgrass clones for grazing conditions. A randomized complete block design was used, with 16 treatments and four replications. Each plot had a total area of 25m2, with the presence of animals. The following parameters were determined: leaf blade accumulation rate (LBAR) above 40cm height and total, stem accumulation rate (SAR), total forage accumulation rate (TFAR), dry matter concentration (%DM), crude protein concentration (%CP) and, neutral detergent fiber (%NDF). The results showed significant difference (P<0.05) between clones and evaluation periods for LBAR above 40cm, total LBAR and TFAR, with mean values of 28.08, 41.62 and 49.18kg/ha/day, respectively. Crude protein and NDF differences (P<0.05) were also found between the clones for all the different parts of the analyzed plant. The forage lost presented a similar chemical composition to the leaf blades above 40cm and to the post-grazing residue. The clones CE-08-AD and Venezuela AD presented a high performance considering the evaluated parameters and may be considered as promising materials.
