Abstract
The study was carried out at the colleges of Agriculture, Kerbala University to determine the effect of thyme ground-leaves added to broiler feeds on the total numbers of bacteria, especially colon bacterium, E.coli, in the broiler alimentary canal and some carcass characteristics. They study, consisted of four nutritional treatments applied on 120chicks one-day old age Hubbard classic broilers of unsexed was initiated on December 7,2008 and terminated on January 19,2009. The thyme ground-leaves were added at rates of 0,5,10 and 15g / kg of feeds by applying completely randomized design (C.R.D.) and using Duncan multiple range for determining significant differences between means of experimental treatments. The results of statistical analysis showed highly significant reduction (P<0.01) in the numbers of total bacteria as well as number of colon bacterium in all experimental treatments compared with control treatment which was devoid of thyme. The addition of thyme ground-leaves, however, had no significant effect on studied characteristics of broiler carcass including whole weight, net weight, weight of edible parts and dressing percentage on the other hand, the control treatment achieved significantly less relative weight of intestines (P< 0.05) when compared with other experimental treatments.
