Abstract

This experiment was made to evaluate the effect of adding leaves powder of (Moringa olifera), fenugreek seeds (Trigonella foenum), dry yeast (Saccharomyces cerevisiae) and mixture (fenugreek + Moringa + yeast) on growth, carcass traits, nutrients digestibility, some blood constituents and economic efficiency of Sasso broiler chicks. A total number of 150 one day age broiler chicks (Sasso) were divided into 5 groups. Each one composed of 3 replicates (10 chicks each). The first group received a basal diet without any supplementations (control). Whereas, second, third, fourth and fifth groups received the control diet supplemented with 0.5% fenugreek seed powder (FSP), 0.5% moringa leaves powder (MLP), 0.5% dry yeast (DY) and 0.5 % mixture as (0.167% FSP + 0.167% MLP + 0.167 %DY). The obtained results showed that there were significant differences among treatments. The birds fed DY recorded improvement (P ˂0.01) in body weight, body gain, crude protein digestibility, dressing percentage, total serum protein, and economic efficiency compared with the birds fed the other feed additives as growth promoters.
