      abstract = {Grass cultivars Mulato (a hybrid; Brachiaria brizantha χ  B. ruziziensis), MarandCi (Β. brizantha) and Toledo (B.  brizantha) are the most important tropical grass releases  in Latin America for grazing. However, information on yield  and persistence of these cultivars in Puerto Rico is  limited. This study assessed yield, nutritive value and mob  grazing effects of Mulato, MarandCi and Toledo. The study  was conducted at the Corozal substation of the Agricultural  Experiment Station of the University of Puerto Rico. Soil  type was of the Corozal series (fine clay, mixed,  isohypetermic Aquic Haplohumults). Established stands of  Mulato, MarandCi and Mulato were stocked every 35 d with  yearling steers (mob grazed for 1 to 2 d to a 15-cm  height). Prior to grazing, a 1 m2 quadrant was clipped,  weighed and dried to determine yield, and sub samples (500  g; four samples in the year) were ground to determine their  chemical composition [crude protein (CP), neutral detergent  fiber (NDF), and acid detergent fiber (ADF)]. All pastures  were mob grazed for 15 grazing cycles to determine changes  in yield over time. Mean yield of Mulato (1,207 kg/ha),  MarandCi (1,094 kg/ha) and Toledo (1,271 kg/ha) were  different (P<0.05), but there were no differences in CP  (6.8%). There was a cultivar effect (P<0.05) on NDF and  ADF, with a lower NDF (64.6%) and ADF 33.6%) for Mulato.  There was a grazing cycle date effect on yield (P<0.05)  consistent with rainfall patterns in the Corozal area.  After 1.5 years of grazing it is evident that all three  cultivars persisted, but that grazing management is needed  (longer periods of regrowth) during the dry periods},
