| 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 The addition of levels of ethanol extract of brown propolis was evaluated by assessing diet degradation in rumen fluid and predicting cumulative in vitro gas production by nonlinear (dual pool logistic and exponential) models. A total of 35 g of crude propolis were extracted in 65 mL of cereal alcohol (95% ethanol). In a completely randomized factorial design, the experimental diets combined four concentrations of extracted propolis diluted in cereal alcohol (0, 50, 70, and 100% of propolis extract) and supplementation doses (4, 8, 12, 16, and 20 mL/kg dry matter), tested in triplicate. Diet (400 g/kg Tifton hay and 600 g/kg concentrate) was incubated for 96 h carried out three times in three different weeks. There was significant interaction... |
