| ABSTRACT The gelatin industry wastewater has nutrients in its composition, allowing its use in agriculture as an alternative to disposal and recycling of this residue. However, high application rates can cause the accumulation of elements such as sodium in the soil, and generate negative impacts on the environment. This study aimed to evaluate the effects of the application of rates up to 600 m3ha-1 of gelatin industry wastewater in soil columns, on soil chemical attributes in five depths. The experiment was conducted in a greenhouse, in PVC tube columns (0.20 m diameter) filled with distroferric Red Nitosol soil, of very clayey texture. The treatments consisted of increasing rates of wastewater equivalent to 0, 150, 300, 450 and 600 m3 ha-1, with a single... |

| ABSTRACT We evaluate the application of treated sanitary wastewater (TSW) to provide potassium for crops and reduce demand for fresh water and mineral nutrients. The field experiment was arranged in randomized block design with four replications and five treatments: 50, 100, 150 and 200% of potassium requirements and a control with conventional fertilizer. The TSW was applied to maize (November 2012 to February 2013), cotton (June to November 2013) and bean (April to June 2014). After bean, soil chemical properties were evaluated until 0.8 m depth. Fertigation with TSW to potassium fertilization provided about 50% of water, nitrogen and phosphorus to the bean. The soil nutrient availability and soil organic matter did not increase, whereas sodium had... |

| Deficiências e desequilíbrios minerais em bovinos são descritas em quase todas as regiões do mundo. Os elementos minerais comumente deficientes para bovinos com dieta exclusiva de pasto são: P, Na, I, Cu, Co, e Se. Em algumas regiões sob condições especificas, Ca, Mg e Mn. Por outro lado, Fe e Mn estão, normalmente, em excesso nas regiões do Cerrado Central do Brasil e Pantanal. A ingestão de dietas deficientes ou desequilibradas de elementos minerais torna mais difícil a manutenção de concentrações ótimas nos tecidos . No inicio, causa lesões bioquímicas que induzem a trocas nas formas de funcionamento, concentração e atividade do elemento nos fluidos e tecidos do corpo. Essas alterações diferem conforme os elementos e suas funções, com o grau de duração... |

| ABSTRACT The aim of this study was to evaluate the anesthetic activity of the essential oil (EO) of Ocimum americanum L. in silver catfish (Rhamdia quelen ). In the first experiment, the depressor effects and chemical composition of the leaf EO (LEO) and inflorescence EO (IEO) were compared. Juveniles (n = 10) were placed in aquaria containing different concentrations of EO (25 - 500 mg L-1) to determine the point at which anesthesia was induced and the length of the recovery period. In the following experiment, the effects of 300 and 500 mg L-1 LEO exposure on stress parameters (plasma cortisol, glucose and sodium levels) after air exposure for 1 min were assayed. Fish (n = 10 per sampling time) were sampled immediately or transferred to anesthetic-free... |

| Voltage dependent sodium channels represent an important target for different neurotoxins and there have been identified different binding sites according to these interactions. The so called site 3 toxins comprise a diverse group of peptides obtained from sea anemones and α-scorpions that bind to voltage gated sodium channels slowing down the inactivation process. These polypeptides vary considerably in their affinities for the sodium channels in different excitable cells. In this work we studied the pharmacological action of three toxins: BcIII (isolated from Bunodosoma caissarum), BgII and BgIII (isolated from Bunodosoma granulifera) on isolated cultured neurons of rat dorsal root ganglia. The biophysical effects and the potency of these polypeptides... |

| ABSTRACT The objective of this study was to determine the ideal requirement of sodium to molted laying hens. The experimental period lasted 105 days, divided into five periods of 21 days. Hisex White laying hens 150 with 84 weeks-of-age were used. The experimental design was completely randomized in a factorial scheme (5x3) with treatments constituted by five levels of sodium (0.10, 0.15, 0.20, 0.25, and 0.30%) in the diets, and three postmolt stages (early = 21 days, medium = 63 days, and final = 105 days). Performance and egg quality results were evaluated by Tukey test at 5%. Eggshell resistance and weight gain results were evaluated by polynomial regression at 5%. Except the yolk height, all performance and egg quality variables were affected... |

| Two experiments were carried out using 712 day-old chicks to evaluate the electrolytic balance (Na+K-Cl) in pre-starter (1-7 days) broiler diets. The feed, based on corn and soybean meal with 21.5 % protein and 2,900 kcal ME/kg, was offered ad libitum. In experiment I, K level was fixed, and Na and Cl levels were changed, using four 4 treatments and eight replicates of 16 birds. In experiment II, increasing levels of Na and K were used, with a total of four treatments and five repetitions of 10 birds. In both experiments, the dietary electrolytic balance was 40; 140; 240 and 340 mEq/kg. Electrolytic balance caused a quadratic effect on weight gain and feed:gain ratio, and a linear increase in feed intake when the electrolytic balance was increased by the... |

| Seven hundred and twenty Ross 308 chicks were raised in a controlled environment room, distributed in a factorial design with 3 hatching chick weights (37, 40 and 44 g), 3 geometric mean diameter (GMD) (0.561; 0.783 and 0.997 mm) and 4 total sodium levels (Na) (0.12; 0.24; 0.36 and 0.48%) in the pre-starter diet (1 to 7 days). From 8 to 21 days (d) one single basal diet was used for all treatments. The thirty seven-gram chicks had the smallest yolk sack weight at 4d, smallest body weight (BW) and feed intake (FI) at 7d and 21d, but the same feed conversion (FC) than the other groups of hatching weight. Chicks receiving diet with intermediate GMD had the greatest BW and FI at 7d, but at 21d this effect was no longer seen. The diet with finest particle size... |

| An experiment with 400 one-day-old male chicks (Ross) was conducted to evaluate the effects of different Na levels (0.10, 0.22, 0.34 and 0.46%) and different cation/anion balances (Na+K-Cl) (100, 150, 200, 250 and 300 meq/kg) in pre-starter diets on broiler performance. The corn and soybean-based diets had 22% crude protein and 2,900 kcal/kg metabolizable energy and were fed ad libitum. Performance data showed a positive quadratic effect of increasing Na levels on feed and water consumption, weight gain and feed conversion. Na+K-Cl also had a quadratic influence on feed intake and weight gain. None of the effects tested affected the amount of water measured in excreta. Derivatives of obtained regression equations pointed to optimal Na levels of 0.45% for... |

| The experiment was conducted to evaluate the effect of feed restriction and different sodium levels in the diet on the performance and hematological values (erythrocyte, hemoglobin, hematocrit, mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration and white blood cell) of broilers from 22 to 42 days of age. A completely randomized design was used in a 4 x 2 x 2 factorial (levels of sodium: 0.16%, 0.19%, 0.22% and 0.25%; with or without feed restriction; male and female), and two replicates of thirty broilers each. Sodium levels did not affect performance (p>0.05). Feed restriction resulted in increased feed intake and affected weight gain and feed conversion negatively (p<0.05). Better weight gain and feed conversion (p<0.05)... |

| Soils of the coastal plains of Rio Grande do Sul, Brazil, are affected by salinization, which can hamper the establishment and development of crops in general, including rice. The application of high doses of KCl may aggravate the crop damage, due to the high saline content of this fertilizer. This study aimed to evaluate the effect of K fertilizer management on some properties of rice plant, grown in soils with different sodicity levels, and determine which attribute is best related to yield. The field study was conducted in four Albaqualfs with exchangeable Na percentages of 5.6, 9.0, 21 and 32 %. The management of KCl fertilizer consisted of the application of 90 kg ha-1 K2O broadcast, 90 kg ha-1 K2O in the row and 45 kg ha-1 K2O in the row + 45 kg ha-1... |

| Under NaCl-salinity Na+ and Cl- accumulation of shoot and root vary greatly among glycophyte plants; this is mostly due to genetic diversity and has been utilized to distinguish between plant responses to salinity. The current study aimed to evaluate the accumulation and Na+ and Cl- tissue partitioning and its effect on dry mass gain and K+ accumulation in one-month-old Prosopis juliflora, Leucaena leucocephala, Piptadenia macrocarpa and Mimosa hostilis seedlings grown for 30 days, in sand watered with nutrient solution loading 100 mol m-3 of NaCl, in greenhouse. The Na+ and Cl- accumulation, but not partitioning between shoot and root, depended on plant species. All the plants accumulated Cl- over Na+ both in shoot and root. The K+ content of plants did... |

| The NaCl effects on the growth and inorganic solute accumulation were studied on 30-day-old cashew plants (Anacardium occidentale L.) hydroponically grown for 8 days (short term) and 40 days (long-term) with NaCl at different levels. The shoot fresh mass yielded after 40 days, in response to 50 and 100 mol m-3 NaCl, decreased by 25 and 75%, respectively. This decrease was markedly low in root fresh mass, which did not change under 50 mol m-3 NaCl and decreased nearly to 30% under 100 mol m-3 NaCl, as compared to control plants. In short-term experiment, salinity induced only slight changes of K+ tissue concentrations in the whole plant. In the long-term experiment, K+ tissue concentrations were substantially decreased, particularly in roots. In response to... |
