Effect of tannins of Albizia lebbekoides on the in vitro fermentation of star grass (Cynodon nlemfuensis) during the dry season
Main Article Content
Abstract
(38.7 mL) was much lower than that of star grass (88.4 mL) and by increasing the inclusion level of legume, the potential and the fractional
rate of gas production of the diet were reduced. The lag phase showed a trend to decline, as the inclusion level of the legume was increased (from 40.1 for star grass to 32.3 in star grass + albizia 30 %). The apparent degradability of dry matter diminished as the inclusion level of th legume was increased. It is concluded that the two inclusion levels of Albizia lebbekoides did not affect the fermentation of the basic diet of Cynodon nlemfuensis, except the 30 % level between 12 and 24 h of incubation. However, the potential kinetic indicators of gas production, the fractional rate, and the lag phase were indeed affected. The tannins affected the gas production and influenced on the kinetic parameters of fermentation.
Key words: Albizia lebbekoides, Cynodon nlemfuensis, gas production, tannins.
