The objective of this experiment was to determine the effect of feeding layers two 28-day periods Corn-soybean meal, Corn-raw white lupin and Corn raw white lupin diets with or without live yeast culture. Overall, our results showed that mean egg production (% hen-day basis), feed conversion (Kg feed/dozen eggs), feed consumption (g/hen/day), egg weight (g), egg mass (g/layer/day) and Haugh units among the dietary treatment were not significantly different (P>0.05). It seems microbial additives need much time to play their role in changing gut ecology which is the key of improving digestion. So two periods are not sufficient to determine the effect of feeding lupin. Additional research with longer experiment is necessary to identify the proper nutritional values of white lupin in layers.
