| ABSTRACT: This study was conducted to evaluate the effect of ractopamine concentrations on swine fat and meat lipid profiles. Ninety finishing barrows, initially weighing 71.9±4.4kg, were distributed in a randomized block design in three ractopamine concentrations (0, 10 and 20ppm) with fifteen replicates of two animals in each. Gas chromatography was used to analyze the lipid profiles of backfat and meat. The inclusion of ractopamine in the diet changed (P<0.05) α-linolenic acid and eicosatrienoic acid concentrations in the backfat but did not affect (P>0.05) any of the other fatty acids or indexes evaluated. In the meat, a significant effect (P<0.05) was observed on nine fatty acids evaluated, with a decrease (P<0.05) in lauric, myristic,... |

| The objective of this study was to evaluate performance, quantitative characteristics of carcass, and visceral responses of barrows maintained on heat stress enviroment and fed diets supplemented with ractopamine. It was used 48 animals with initial weight of 67.3 ± 3.8 kg, distributed in a randomized block design with four levels of ractopamine (0, 5, 10 and 20 mg/kg), each one with six replicates with two animals each. The experimental period lasted 28 days. Air temperature was 31.8 ± 2.0ºC, air humidity was 72.6 ± 10.2% and BGHI was 82.7 ± 2.8. Daily feed intake was not affect by the levels of ractopamine but they improved feed conversion and increased daily weight gain and final weight of the animals. The carcass quantitative characteristics were not... |

| O objetivo do trabalho foi avaliar o desempenho e as características quantitativas de carcaça de suínos machos castrados e imunocastrados, sob alimentação à vontade ou restrição quantitativa. Foram utilizados 240 animais, com peso inicial de 91,49±3,26kg, distribuídos em delineamento experimental de blocos ao acaso, em esquema fatorial 2x2 (dois manejos alimentares e duas categorias), com quatro repetições e 15 suínos cada. Suínos sob restrição alimentar apresentaram consumo inferior (P<0,05) em relação aos alimentados à vontade. O consumo de ração não diferiu (P>0,05) entre castrados e imunocastrados. Suínos alimentados à vontade apresentaram maior (P<0,05) ganho de peso em relação àqueles sob restrição. Os imunocastrados apresentaram ganho... |

| ABSTRACT: To evaluate inclusion levels and residual effects of diets containing yeast extract (YE) plus blood plasma (BP) on the performance of 36 to 60-days old piglets, 105 piglets were used (8.75±0.72kg), and they were distributed under a randomized block experimental design with five treatments (control - 2.0% BP; 1.0% BP plus 0.0, 1.0, 2.0, or 3.0% YE), seven repetitions, and three animals per experimental unit. Piglets were given experimental diets from 36 to 49 days of age. From 50 to 60 day of age, all piglets received the same diet. No effects from treatments (P>0.10) were observed on the performance variables from 36 to 49 day of age. From 50 to 60 day of age, an effect was observed from YE levels on the daily feed consumption (P<0.03),... |

| The objective of this study was to evaluate the inclusion of yeast extract as a partial replacemer of blood plasma in piglet diets and its effect on the performance and intestinal morphometry of pigs weaned at 21 days of age. One hundred and twenty animals were randomized into blocks, with five diets (4.0% blood plasma; 2.0% blood plasma with 0.0; 1.0; 2.0 or 3.0% yeast extract), six replicates and four pigs per experimental unit. At 35 days of age, one pig per experimental unit was slaughtered in order to evaluate duodenal and jejunal morphometry. The levels of yeast extract had a quadratic impact on daily feed intake and final weight, which increased up to the estimated level of 1.91%. Daily weight gain and feed conversion rate were not affected. A... |
