Soaking Panicum maximum var. maximum, P. maximum var. trichoglume and Chloris gayana in 0.75 or 1.50% NaOH solution at 20 ø C for 24 h increased NDF, ADF, cellulose acid detergent lignin, DM digestibility and acetyl bromide lignin digestibility but decreased CP, ash and silica. Hemicellulose content was reduced by 0.75% NaOH but increased by 1.50% NaOH. DM recovery was higher with 0.75% NaOH whereas DDM recovery and in vitro DM digestibility were higher with 1.50% NaOH. It is concluded that 1.50% NaOH treatment is most effective for improving nutritive value of tropical grasses.

This abstract relates to the following species:

Chloris gayana, Panicum maximum
