A total of 200 day-old male broiler chicks were randomly assigned into five experimental treatments each with four replicates of 10 chicks. The treatments were feeding of commercial diet as a control (CD) and the same supplemented with M. chamomilla at 0.3 (MC-0.3), 0.6 (MC-0.6), 0.9 (MC-0.9) and 1.2 (MC-1.2) per cent levels. The addition of MC did not affect feed consumption. Although there were no differences (P>0.05) among the groups at any of the periods in the feed intake, BW gain and feed conversion ratio. There were, however, differences (P<0.05) in the European production index (EPI) with the index for chickens fed MC-0.6 being higher as compared with all the other treatments. The immune response to Newcastle disease was higher in MC-0.9 and MC-1.2 groups. The counts of lactobacilli in the intestinal digesta were higher (P<0.05) in broilers receiving MC-0.6 and MC-0.9 diets than those fed on the CD diet. In respect of plasma clinical biochemistry, differences (P<0.05) were found in glucose, HDL and uric acid for the different treatments when compared with the control, but the values were within the normal range for poultry. Overall, the present study indicates that the positive effects, if any, of dietary supplementation of chamomile in broilers apparently failed to present a definite trend. Thus, further evaluation is needed in order to establish the proper use, the level of supplementation and the potential beneficial effects that M. chamomilla would impart in broilers.||URI:||http://hdl.handle.net/10553/106804||ISSN:||0972-2963||DOI:||10.5958/0974-181X.2020.00007.4||Source:||Animal Nutrition and Feed Technology [ISSN 0972-2963], n. 20, p. 71-81|
