Extract

It has been suggested that the beneficial effects of yucca plant (Yucca shidigera) extract when used as a feed additive are based on its demonstrated ability to bind ammonium (Cromwell, et al., 1985; Johnston, et al., 1981). Benefits include the reduction of noxious gasses, the easing of waste management problems and the enhancement of livestock performance. However the amount of ammonium bound is very small (Ryan, et al., 1993; Quinn and Leek, 1994), and it is difficult to explain the observed enhancement of livestock performance, particularly in ruminants, in terms of this effect alone. Consequendy, in order to evaluate the overall effect of Y. shidigera extract on rumen fermentation in this study, samples of ruminal fluid from pre-conditioned hay-fed sheep were incubated with the extract and die effects on ammonium, pH and short chain fatty acids after 24 h were compared.
