Effects of alfalfa saponin on fermentation functions and protozoal populations in the rumen of sheep

摘要：

Alfalfa Saponins are secondary plant glycasides with a polycyclic aglycone moiety of triterpenoid attached to carbohydrate moiety.Several biological effects have been ascribed to Alfalfa Saponins in nonruminant animals, Some effects in ruminants were pronounced.However,little is known about the effect of alfalfa saponins on microbial fermentation in the rumen.Protozoa,together with bacteria and fungi,are an integral part of the rumen microbial population, all are involved in rumen fermentation and digestion of feed.The objective of this study was to investigate the effects of supplementing sheep with different levels of alfalfa saponins on ruminal fermentation,protozoal populations and to provide some valuable data for use of alfalfa saponins in sheep production.
