Forage quality evaluation with several grasses grown at a high altitude pasture situated at 1,000m above sea level was made to determine what is the feed value of these grasses and whether these grasses have any differences in forage quality compared with the grdsses grown at lowland pastures. In this experiment, Common, Venture, and Palaton reed canarygrass (Phahris arundinucea L.) and Climax timothy (Phleum pratense L.) were used and harvested at two different dates, 5 July and 30 September, 1989. Cmde protein (CP) concentrations in the grasses grown in September were higher than in July. Among the grasses grown, Palaton and Common reed canarygrass were highest in CP concentration in July and September, respectively. Acid detergent fiber (ADF) and neutral detergent fiber (NDF) concentrations in the grasses harvested in July were higher than in September. Palaton reed canruygrass was lowest in ADF and NDF concentrations at the both harvest dates. Relative feed value (RFV) in the grases harvested in July was ranged from 92 to 105 and that in September was from 110 to 117. Palation reed canarygrass had the highest RFV of 105 and 117 in July and September, respectively, therefore, the forage quality of this grass was ranked as Grade 2 based on the AFGC Hay Quality Standards. Overall forage quality of the grasses grown at a high altitude pasture seemed to be higher than the forage quality at lowland pastures. Based on the RFV assigned by the AFGC, forages with RFV 92 to 117 in this experiment could only work well in rations for low producing dairy cows.
