AbstractThe objective of this study is to determine the effect of diet supplementation with coriander seed and rosemary leaves or a mixture for them on biochemical characteristics of blood, immune organs and bacteria count in meat of broiler carcass (colony forming unit/g). A total of 1080 broiler chicks , Ross-308 at one day old, were randomly allocated for nine treatment groups . Chicks in each treatment group were subdivided for three replicates with 40 chicks for each replicate. Chicks in the first and second treatment are fed on diet supplemented with coriander seed (0.25 % and 0.50 % ) , respectively . While, chicks in the third and fourth treatment are fed diet with rosemary leaves (0.25 % and 0.50 %) , respectively . Also, Mixed of the two medical herbs are added to fifth, sixth, seventh and eighth treatment .Whereas, chicks in the ninth treatment are fed diet without medical herbs supplementation and used as a control group. At marketing age (42d) 12 blood samples are taken to measure the total protein and glucose in serum. Also 9 birds from each treatment group are culled to determine Bursa and spleen weight. Also, the relative weight of Spleen and Bursa Index are calculated. Total bacteria count (colony forming unit(cfu)/ g )and coliform and Salmonella in each one gram of mixed meat from each treatment are recorded.
Data show that dietary treatment doesn't significantly affect the serum protein contain, relative weight of bursa and bursa index. However the dietary treatment is significantly ( p < 0.05) increases the serum glucose and spleen relative weight . Total bacteria count, coliform and salmonella count are not affected by dietary treatment.
In conclusion, diet supplementation with Rosemary or coriander seed has an effect on biochemical characteristics of blood, immune organs and bacterial count.
