| ABSTRACT: This study was conducted to assess the use of propolis ethanolic extract as an alternative to performance-enhancing antibiotics for piglets. Seventy piglets weaned at 21 days of age, with initial weights of 7.3±0.4kg and final weights of 24.9±1.2kg, were randomly assigned to five diets: positive control (diet with 200ppm antibiotic); negative control (diet without growth promoter); and diets with 100, 500, and 1,000ppm of brown propolis ethanolic extract, with seven replicates of two piglets each. The duration of the experimental period was 35 days. The diets did not influence (P>0.05) daily feed intake, daily weight gain, final weight, and feed conversion of animals. The bacteriological profile of the nasal swab presented a predominance of... |

| ABSTRACT Propolis produced by selected bees Apis mellifera were collected from March to June of 2013 and in March of 2015 and analyzed in order to evaluate the influence of climate, colony of origin, and food supplementation of colonies on the content of total phenolic and flavonoid by chromatographic analysis and antioxidant activity by radical scavenging of 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and ferric reducing antioxidant power (FRAP) methods. The Principal Component Analysis (PCA) was carried out with propolis collected in 2013 and two clusters were formed. Propolis produced in the months of March and April showed a higher content of total phenolic compounds (TPC) and... |
