| ABSTRACT Because of the importance of the ambiance in swine facilities, this study aimed to evaluate the air quality, the sound pressure level, and the thermal environment of two distinct swine nursery styles. A completely randomized block design with a split-plot arrangement was used, in which the main plots were composed of the nurseries and the external environment; the subplots were the hours; and the replications were the collection days. Air temperature data (ºC), relative humidity (%), and black globe humidity index (BGHI) data were collected throughout the day at 10-min intervals, with means compared by Tukey’s test at 0.05 probability level. Instantaneous concentrations of ammonia (ppm), carbon dioxide (ppm), and sound pressure levels (dB(C)) were... |

| The aim of this work was to verify the effect of different levels of true digestible lysine (TDL) and crude protein (CP) on diets on the carcass composition of the swine in the nursery phase. Eighty piglets Landrace x Large White, barrows and females, with initial weight of 9.1±1.2 kg and final weight of 21.5±4.8 kg, weaned at the 28 days, allotted in groups of two during 35 days in the nursery. A randomized block design in factorial 2x4 (two levels of CP - 16 and 18% - and four of TDL - 0.7; 0.9; 1.1 and 1.3%) with five repetitions was used. After weighing, one animal of each stall was sacrificed and the carcass utilized for determination of water (CWP), protein (CPP) and lipid (CLP) percentage and deposition tax of the protein (DTP) and lipid (DTL).... |

| The histological changes in the spleen and the immunohistochemical expression of visfatin in lipopolysaccharide-stimulated piglets are reported to examine the relation between visfatin and inflammation. The results are as follows: (1) After LPS treated, the spleen displayed thicker capsules and trabecula, the thinner periarterial lymphatic sheath, and the more expandable splenic sinusoid, with an increase in the number of splenic nodules, lymphocytes, ellipsoids of the marginal zone, red blood cells and macrophagocytes. (2) Visfatin-positive cells were mainly distributed in the red pulp of the spleen, with less in splenic nodules and periarterial lymphatic sheath. In the LPS-treated group, the signal intensity and quantity of the visfatin-positive cells... |

| ABSTRACT The present study evaluated the effect of variation in the amount of total dietary fiber (TDF) in sow diets, provided from 74 to 114 days of gestation, on the digestibility of nutrients and energy during gestation, as well as productivity and metabolism during gestation and lactation. Thirty-three sows were used in a randomized experimental design. The amounts of TDF in three treatment diets were 156, 223, and 282 g kg−1. The daily intake of nutrients and energy was similar for all diets the entire period of gestation, differing only in the volume of ration consumed, which was 2.1, 2.2, and 2.4 kg day−1 (days 74 to 90) and 2.5, 2.6, and 2.8 kg day−1 (days 91 to 111) for the 156, 223, and 282 g kg−1 TDF diets, respectively. During gestation, the... |

| Two experiments were carried out to study the effects of grinding of soybean hulls (SH) on starting pigs (15-30 kg) diets. Experiment I consisted of a digestibility trial with 12 barrows, initial average body weight 21.9±1.29 kg, in which the best digestibility coefficient (DC) of DM and GE was obtained with SH ground through a 2.5mm screen mesh, evaluated for CP and ME, a best DC was attained with 3.0 mm screen mesh. In the Experiment II, five diets with increasing SH (2.5 mm) levels (0, 3, 6, 9 and 12 %) for starting piglets were formulated. A quadratic response in daily weight gain (DWG) occurred, according to SH inclusion. Worst DWG occurred at 7.75 % SH inclusion. Daily feed intake, feed: gain ratio and plasma urea nitrogen were not affected by... |

| Group B rotaviruses (RV-B) were first identified in piglet feces, being later associated with diarrhea in humans, cattle, lambs, and rats. In human beings, the virus was only described in China, India, and Bangladesh, especially infecting adults. Only a few studies concerning molecular analysis of the RV-B NSP2 gene have been conducted, and porcine RV-B has not been characterized. In the present study, three porcine wild-type RV-B strains from piglet stool samples collected from Brazilian pig herds were used for analysis. PAGE results were inconclusive for those samples, but specific amplicons of the RV-B NSP2 gene (segment 8) were obtained in a semi-nested PCR assay. The three porcine RV-B strains showed the highest nucleotide identity with the human WH1... |

| Lysine requirements for gain in maternal body reserves and piglet birth weight, during pregnancy, in contemporary prolific genotypes, are not well established. This study aimed to evaluate the effect of dietary lysine in late pregnancy on piglet birth weight, and on the gestational and lactational performance of gilts. Pregnant gilts were uniformly distributed into two groups and received, from 85 to 110 days of gestation, either of two lysine levels in their diet: Control group - 28g lysine/day (n=136), and Lysine group - 35g lysine/day (n=141). There were no effects (P>0.10) of supplemental lysine on body weight and backfat (BF) gain of females or on piglet birth weight. Gilts supplemented with lysine tended to have a lower percentage of stillbirths... |

| O objetivo deste trabalho foi verificar se a ingestão diária de diferentes quantidades de lisina digestível, pelas fêmeas suínas primíparas em lactação, influencia o desempenho produtivo, reprodutivo e o perfil sangüíneo dessas matrizes. Utilizaram-se inicialmente 50 porcas primíparas em lactação, distribuídas em 5 tratamentos (10 animais por tratamento), correspondendo a 0,88; 0,99; 1,04; 1,08 e 1,24% de lisina digestível na ração. Utilizou-se delineamento experimental de blocos ao acaso, sendo cada matriz considerada uma unidade experimental. Os resultados foram avaliados através de modelos estatísticos de análise de variância, utilizando-se a regressão linear ou quadrática conforme o melhor ajuste. As variáveis de desempenho das matrizes (perda de peso,... |

| One hundred ninety two swine were used in a trial to assess the relative bioavailability of phosphorus (RBP) in six phosphate sources. Phosphates were three feed grade phosphates (FP), two made in Brasil, and one USA made, and three rock phosphate samples (RP) originated from two mines sites in Brasil, and one mine site in Israel. Levels of calcium, phosphorus and fluorine in RP were 29, 12 and 1.7% (RP source 1), 33, 14 and 1.4% (RP source 2), and 30, 14 and 3.6% (RP source 3), respectively. Pigs were fed a corn-soybean meal basal diet (18% CP, 0.95% Lys, 0.75% Ca, 0.37% P) or the basal diet with 0.15% P from a standard purified grade calcium phosphate (SP), or with 0.15% P from experimental FP or RP. Each diet was fed to six pen replicates of four pigs... |
