SUMMARY

In a metabolism trial eighty broiler chicks (Lohmann) were given diets with four levels of whole sunflower seed (WSS) (0, 7.5, 15 and 22.5%). Increasing the dietary level of WSS had no signifi cant (P>0.05) effect on nitrogen intake and excretion. However, there was a linear increase (P<0.05) in nitrogen retention (g/day and as percentage of intake) with each increment increase in WSS. No significant differ­ences were noted for energy intake, excretion and retention due to the dietary treatment. Inclusion of USS up to 22.5% in broiler Chicks diet had no significant effect on daily weight gain. feed intake and feed conversion ratio.
