growth performance and biochemical parametersof broiler chickens on diets consist of chicory (cichorium intybus) and nettle (urtica dioica) with or without multi-enzyme

a total of 288 broiler chickens (1 d old) were used in a 42-d growth trial to study the effects of chicory (cichorium intybus) and nettle (urtica dioica) with or without multi-enzyme on growth performance, carcass traits, and biochemical parameters. the corn-soybean based control diet and 8 experimental diets were fed to each of 3 pens of chickens (12 chickens/pen). treatments were as follows: 1. basal diet (b), no additives, 2. b + 0.05% enzyme (e), 3. b + 1% chicory (c), 4. b + 1% nettle (n); 5. b + 1% n + e (ne), 6. b + 1% c + e (ce), 7. b + 0.5% n + 0.5% c (nc), 8. b + 0.5% n + 0.5% c + e (nce). a higher body weight gain were found at 42 d of age in chickens fed the e, ce, ne, and nce in diet (p
