The effect of Aspergillus niger waste, a by product of citric acid extraction (yeast waste) on in vitro digestibility of alfalfa hay at different times of incubation (24 and 48h) and fattening performance of male lambs studies. Different levels (five, 10, 15 and 20 percent) of yeast waste were added to alfalfa hay and subjected to the in vitro digestibility trial. In fattening trial, twenty Sanjabi lambs (20.8 kg initial BW, three months of age) divided into two groups in a CRD design. The use of yeast waste of different levels, increased Dry matter (DM) and organic matter (OM) digestibility of alfalfa hay at initial 24 h of incubation (P< 0.05) but the difference in digestibility at the last 48 h of incubation was not significant. Average daily gain, FCR and DM intake and carcass parts between treatments were not significant.
