Abstract :

Crude Protein (CP) from Wolffia meal [Wolffia globosa (L). Wimm.] was used to replace CP from
Soybean Meal (SBM) in the diets of broilers to determine its effect on the broiler’s productive performance
and carcass characteristics. Using Completely Randomize Design, 384 ten-day-old broilers were divided
into 4 treatments; each treatment consisted of 3 replicates of 16 birds each. The treatments were T1: control diet, T2, T3 and T4: 25, 50 and 75% of CP from SBM was replaced by CP from Wolffia meal, respectively. The results indicated that feed intake, average daily gain, feed conversion ratio, protein efficiency ratio and carcass characteristics of control group were better (p<0.05) than other groups. Skin pigmentation of broilers increased with increasing CP replacement from Wolffia meal. It was concluded that less than 25% of CP from SBM could be replaced by CP from Wolffia meal in broiler diets.
