| ABSTRACT This study was carried out to evaluate the levels of digestible phosphorus in diets for barrows with a high potential for lean meat deposition from 50 to 80 kg. Eighty barrows, with an initial weight of 47.93±3.43 kg, were distributed in completely randomized blocks, with each group given five levels of digestible phosphorus (1.86, 2.23, 2.61, 2.99, and 3.36 g kg−1). There were eight replicates, and two animals per experimental unit. Phosphorus levels did not significantly influence feed intake, weight gain, or feed conversion ratio. Daily digestible phosphorus intake increased linearly as levels of phosphorus in the diet were increased. Phosphorus levels did not significantly influence muscle depth, loin eye area, backfat thickness, or the... |

| ABSTRACT The objective of this study was to evaluate sequential digestible phosphorus levels for gilts from 30 to 100 kg. Sixty gilts were used, with an initial weight of 29.98±3.37 kg and final weight of 100.66±8.82 kg, distributed in a randomized block design, with five nutritional digestible phosphorus levels: 2.19-1.88-1.68, 2.69-2.38-2.18, 3.19-2.88-2.68, 3.69-3.38-3.18, and 4.19-3.88-3.68 g kg−1, respectively, for the growth phases 30 to 50 kg, 50 to 70 kg, and 70 to 100 kg, with six replicates and two animals per pen. The nutritional plans did not influence the final weight, days to reach 100 kg, total and daily weight gain, total and daily feed intake, crude protein intake, digestible lysine intake, or metabolizable energy intake. An increase in... |

| 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... |
