Article Synopsis
- - The study tested the impact of low-bush wild blueberry (LBP) and organic American cranberry (CRP) pomaces, with or without a multienzyme supplement (ENZ), on broiler chickens' growth, organ weight, and plasma metabolites over a 35-day period.
- - Results showed that birds fed BMD were heavier and had better feed conversion compared to those receiving berry supplements; however, LBP led to heavier liver weights and altered plasma metabolite levels, particularly in enzyme-fed birds.
- - Overall, the ENZ did not enhance the growth performance of the broilers, but indicated potential metabolic modulation effects from berry pomaces, with LBP boosting weight in the starter phase and CRP in
Feeding practices have been found to influence gut microbiota which play a major role in immunity of poultry. In the present study, changes in cecal microbiota and humoral responses resulting in the 55 ppm bacitracin (BACI), 1% each of cranberry (CP1) and wild blueberry (BP1) pomace alone or in combination (CP+BP) feeding in broiler Cobb 500 vaccinated or not against coccidiosis were investigated. In the non-vaccinated group, no significant treatment effects were observed on performance parameters.

They have been identified as potential antibiotic alternatives in animal feed, but their antioxidative capacity for maintaining or improving the meat quality in broilers is not well documented. This study was to determine whether cranberry and wild blueberry pomaces in diets could positively influence the broiler meat quality.

A total of 2,800 male day-old broiler Cobb-500 chicks were randomly distributed between 10 diets: control basal diet; basal diet with bacitracin (BACI); four basal diets with 1 and 2% of cranberry (CP1, CP2) and blueberry (BP1, BP2) pomaces; and four basal diets supplemented with ethanolic extracts of cranberry (COH150, COH300) or blueberry (BOH150, BOH300) pomaces. All groups were composed of seven replicates (40 birds per replicate).
