Abstract

The objective of this research was to evaluate the forage production, crude protein and neutral detergent fiber level, stocking rate of three forage systems compounds for Coastcross-1 (Cynodon dactylon L. Pers.) + ryegrass (Lolium multiflorum Lam., cv. Comum); Coastcross-1 + ryegrass + red clover (Trifolium pratense L., cv. Estanzuela 116) and Coastcross-1 + ryegrass + white clover (Trifolium repens L., cv. Yi). The experiment was carried out from April 2007 to April 2008, for 11 grazing cycles, six in winter season and five in summer season. Holstein cows receiving 0.9% of body weight/day feed supplement concentrate were used. The herbage mass of pre and post-grazing, botanical and morphological composition crude protein and neutral detergent fiber level were evaluated. A randomized complete design was used with three treatments (forage systems) two replications (paddocks) and independent evaluations (grazing cycles). Superior value (P<0.05) of forage production and daily dry matter accumulation rate were found in winter season for the forage systems with legume. No differences in dry matter disappearance rate and stocking rate averages were detected among pastures. Residual effects of red clover were observed on Coastcross-1 + ryegrass with superior result (P<0.05) on crude protein and lower neutral detergent fiber level.
