Abstract

This study was conducted to determine the effects of dietary supplementation of probiotic and peppermint dry leaves on productive, physiological and immunological performance of a Mandarah strain during the early laying period. 250 chickens of Mandarah strain, 20 weeks old, were used, and they were divided into five treatments with five replicates in a completely randomized design. The experimental groups were either fed a corn soybean meal basal diet control group (T1) or a basal diet supplemented with either probiotic 0.5g/kg diet (T2), probiotic 1g/kg diet (T3), peppermint 15 g/kg diet (T4), or peppermint 20 g/kg diet (T5). The results obtained confirmed that dietary supplementation of probiotics or peppermint dry leaves to the Mandarah laying hens diets, led to significant improvement (P<0.0001) in the measurements of productive, physiological and immunological performance of a Mandarah strain during the early laying period.

Key words: Poultry, dietary supplementations, immunological performance.
