Effect of Supplementation Locally Probiotic, Imported Bakery Yeast and Multi Enzymes in the Performance of Broiler

Abstract

This study was conducted in the poultry farm of the Backrajw station / College of agriculture / University of Sulaimani, from 27 - 4 - 2004 until 8 – 6 -2004, the objective of the study was to investigate the effect of using Local Probiotic, Imported Bakery Yeast and Multi- Enzymes on the performance of broiler . Six hundred and ninety six one day old (Cobb 500) broiler chicks were used. The birds were randomly distributed to eight treatments – groups with three replication per treatment: Control (T1), 0.5% Probiotic (T2), 0.1% Yeast (T3), 0.1% Multi-Enzymes (T4), 0.5% Probiotic + 0.1% Yeast (T5), 0.5% Probiotic + 0.1% Multi-Enzyme (T6), 0.1% Yeast+ 0.1% Multi-Enzymes (T7), and 0.5% Probiotic + 0.1% Yeast + 0.1% Multi-Enzymes (T8). Results showed that: - The feeding of Local Probiotic either alone (T2) or with Imported Yeast (T5) and with Multi- Enzymes (T6) led to improving (P<0.05) live weight, weight gain and feed efficiency.
