| ABSTRACT This experiment was conducted to evaluate the growth performance and carcass characteristics of gilts from 25 to 100 kg body weight (BW) fed diets with increased net energy (NE) levels. Seventy-two gilts with initial BW of 23.24±2.47 kg were allotted to one of six dietary treatments (2300, 2380, 2460, 2540, 2620, and 2700 kcal NE kg−1) using a completely randomized block design, with two pigs per replicate, and six replicates per treatment. Corn-soybean meal-based diets were formulated to be fed in three phases (25 to 50, 50 to 70, and 70 to 100 kg BW). Soybean oil was added to replace the inert ingredient kaolin to meet the NE level of each diet. Increasing dietary NE decreased the average daily feed intake (ADFI) and improved the feed:gain ratio... |

| ABSTRACT This experiment was conducted to evaluate growth performance and carcass characteristics of barrows from 25 to 100 kg fed diets with different dietary net energy (NE) levels. Seventy-two barrows with initial body weight (BW) of 25.19±2.13 kg were allotted using a completely randomized block design to one of six dietary NE treatments (2300, 2380, 2460, 2540, 2620, and 2700 kcal kg−1), which had two pigs per replicate and six replicates per treatment. Diets were formulated to be fed in three phases (25 to 60, 60 to 70, and 70 to 100 kg BW). The six different dietary NE densities were met by adding soybean oil in place of the inert ingredient (kaolin) to a corn-soybean meal-based diet. Increasing dietary NE decreased average daily feed intake and... |

| ABSTRACT The purpose of this study was to evaluate the effect of glutamine supplementation plans on performance, carcass yield, and cut yield of broilers reared in a high-temperature environment. A fully randomized design was adopted for the experiment, comprising 900 male Hubbard broiler chicks assigned to five treatment groups (0% glutamine from one to 42 days of age; 0.5% glutamine from 1 to 7 days of age, followed by 0% from 8 to 42 days; 1.0% glutamine from 1 to 7 days of age, followed by 0.5% from 8 to 14 days and 0% from 15 to 42 days; 1.5% glutamine from 1 to 7 days of age, followed by 1.0% from 8 to 14 days, 0.5% from 15 to 21 days, and 0% from 22 to 42 days; 2.0% glutamine from 1 to 7 days of age, followed by 1.5% from 8 to 14 days, 1.0% from 15... |

| ABSTRACT: This study was conducted to evaluate the effects of net energy levels on the lipid profile of adipose tissue and muscle of swines. A total of 90 animals, with initial weight of 71.94±4.43kg, were used, and distributed in a randomized block design in five net energy levels (2,300, 2,425, 2,550, 2,675, and 2,800Kcal kg-1 feed), with nine replicates and two animals per experimental unit. Lipid profiles of adipose tissue and muscle were analyzed using gas chromatography. Increasing the levels of net energy using soybean oil, improved the lipid profile of adipose tissue and muscle, increased linearly (P<0.05) the concentrations of polyunsaturated fatty acids, especially linoleic and α-linolenic acid, reduced linearly (P<0.05) the monounsaturated... |

| 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 evaluate nutritional plans of digestible phosphorus for barrows weighing between 30 and 100 kg. Eighty animals were distributed in a randomized block design with five nutritional plans containing 2.19-1.86-1.71, 2.57-2.23-2.09, 2.94-2.61-2.46, 3.32-2.99-2.84, and 3.70-3.36-3.32 g of digestible phosphorus kg−1 of diet, respectively, for the phases of 30 to 50 kg, 50 to 70 kg, and 70 to 100 kg, with eight replications and two barrows per experimental unit. The nutritional plans of digestible phosphorus had no effect on the final body weight, feed intake, daily weight gain, or feed conversion of barrows. The daily intake of digestible phosphorus increased with the dietary concentrations of digestible phosphorus. Of the... |

| 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,... |
