In: Egyptian poultry science journal 2005.v.25(IV)Summary: The objective of this investigation was designed to evaluate the influence of substituting soybean meal (SBM) with graded levels (0, 2, 4 and 6%) of dried yeast (DY, Saccharomyces cerevisiae) in the starter and finisher diet, on performance of broiler chicks. A total number of one hundred and twenty unsexed one-week old Arbor Acres broiler chicks were used. Chicks were randomly distributed into four equal experimental groups.Each experimental group had three replicates, ten chicks each. Starter and finisher diets were formulated to include 21% CP, 2900 Kcal ME /kg diet and 17.5% CP and 3100 Kcal ME /kg diet, respectively. The following findings were obtained during the entire period (7 weeks of age) as follow: Live body weight (LBW) and live body weight gain (LBWG) values of chicks fed diets containing 2 or 4 % DY were not significantly different from those fed the control diet. While, significant differences were appeared between chicks fed the control diet and those fed diet containing 6% DY. Also, significant differences in feed intake (FI) were remarked between both the control group and the treatment of 2% DY and both of the other two experimental treatments of 4 and 6% DY. Moreover, increasing DY level in the diet decreased FI, and the experimental group fed 6% DY insignificantly recorded the least value. Feed conversion (FC), carcass characteristics, specific gravity, crude protein conversion (CPC), caloric efficiency ratios (CER) and chemical analysis of blended carcass flesh were not significantly affected by different experimental treatments. Furthermore, increasing of DY level up to 6% in the diet of broiler chicks, relatively reduced the cost of feed / Kg body weight gain, compared to the control diet, which had the highest price. DY supplemented diets up to 6% improved economic and relative economic efficiency. In conclusion, DY could replace of soybean meal in broiler chicks diet up to 6% without any decline effects on performance and economic efficiency of broiler chicks.
