Effects of Various Dietary Levels of whole Sunflower Seed on Energy and Nitrogen Balance of Broiler Chicks

Abstract

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 differ
ences 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.
