ABSTRACT This study investigated the effect of transformed Lactobacillys reuteri on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens. A total of 480 broilers were assigned to six treatment groups and fed a phosphorus-adequate diet, a phosphorus-deficient diet, or a phosphorus-deficient diet containing different L. reuteri recombinants. The results showed that transformed L. reuteri decreased the pH in the duodenum and jejunum of chickens at day 21, decreased drip loss and cooking loss of muscles, and improved muscle tenderness of chickens at days 21 and 42, but did not affect carcass characteristics and only slightly decreased abdominal fat. Transformed L. reuteri also significantly... |

ABSTRACT This study aimed to evaluate the hematological profile, hepatic function, and histopathology of mixed-sex broilers fed rations supplemented with microencapsulated essential oils from Cymbopogon flexuosus (lemon grass) and Lippia rotundifolia (chá-de-pedestre). One hundred and fifty Cobb chicks were housed in cages from 1 to 42 days of age in a completely randomized design, with six replicates with five chickens in each of five treatments (150 total chicks): basal diet without antibiotic growth promoter (negative control), diet with enramicina and salinomycin (positive control), diet with lemon grass essential oil, diet with L. rotundifolia essential oil, and diet with a mixture of lemon grass and L. rotundifolia essential oils. Mean corpuscular... |
