Neospora caninum is considered in many countries as one of the key abortion agents in cattle. This study aims to investigate the parasite behavior in dairy cattle in the municipality of Avaré, SP, Brazil, where abortions frequently occur. An ELISA was performed to compare two samplings on a total of 615 animals; tests were performed in the same herds with a gap of 3 years. An increase in the percentage of reactive animals was observed, ranging from 21.6% at the first sampling to 38.9% at the second sampling. Of the 176 animals tested at both samplings, 61.93% retained a non-reactive status, 15.9% retained a reactive status, 19.88% switched from non-reactive to reactive and 2.27% switched from reactive to non-reactive. Of the 100 animals with reproductive disturbances, 50% presented anti- Neospora antibodies, thereby indicating the presence of the protozoa. When comparing cows and their respective female offspring, a predominance of horizontal infection was observed. Moreover, considering the significant percentage of animals that switched from non-reactive to reactive and the abundant presence of dogs among the herds, the N. caninum transmission may be attributed to presence of carnivores. © Springer-Verlag 2012.

The objectives of this study were to validate a non-extractive RIA for seminal testosterone and quantify the hormone using a solid-phase commercial kit, and study the correlation between testosterone in seminal plasma and sperm characteristics. Parallelism showed a correlation index r = 0.992 (Y = -5.47 + 1.073X; R 2 = 0.985), indicating that the nonextractive method presented is indicated particularly for assessment of testosterone when establishing comparisons between samples. Overall mean (±SD) of testosterone level was 0.60±0.65 ng/mL. Correlation was only found between the seminal concentrations of testosterone and pH of the semen. © 2011 Sociedade Brasileira de Zootecnia.

There are few studies for the crambe crop (Crambe abyssinica Hochst), and studies that characterize the sufficiency level of K in the soil and leaves are indispensable to support future programs potassium fertilization for this crop of fall/winter. An experiment was carried out to investigate the response of crambe to K soil. The experiment was carried out on a clayey Red Latossol under no-till in Botucatu, São Paulo State, Brazil. Treatments consisted of seven K levels in the soil, resulting from the application year (2000 to 2010), the summer crop (soybean), 0, 30, 60, 90, 120, 150 and 180 kg ha-1 K2O. Before starting the experiment, soil samples were collected at depths of 0-20 cm and soil K contents determined by the resin and Mehlich-1 method. The sufficiency levels of K in soil and leaves were obtained considering the relative yield of 90%. When the levels of soil K extracted by resin and Mehlich-1, are above 88 and 94 mg dm-3, respectively, equivalent to 26 g kg-1 K in the leaves, the increase in crop yield of crambe is unlikely. These values should match the sufficiency level of crop and are sufficient to achieve relative grain yield of 90%.

Pain is an unpleasant sensory or emotional experience that follows the application of a noxious stimulus. Can be experienced with or without the concomitant occurrence of physical stress signs, which occurs frequently in animals caused by trauma, systemic disease or surgical procedures. The control depends on length, where there are painful impulses and mental status of the animal. It is an important clinical condition, resulting in suffer that will affect quality life. This paper is a review of pathophysiology and pain control in small animals.

In order to have a good visual analysis for the seabed, we created a 'virtual-seabed' according to the real one. The 3D seabed platform in this poster is based on a 'section-drilling' model that can accomplish the modeling, visualization and analysis of the integrated data of the seabed on either website or smartphone.

The objectives of this study were to evaluate the mineral nutrition and the response of physic nut to potassium fertilization as well as to assess whether the species can absorb K from the non-exchangeable soil fraction. The study was conducted in a greenhouse, in randomized blocks, and with four repetitions. Physic nut plants were cultivated in plastic recipients filled with 50 dm3 of a Dark Red Latosol fertilized with rates of 0, 40, 80, 120 and 160 mg K dm-3 of soil. One hundred and fifty days after planting, the height, stem diameter and leaf area of the plants were measured, and the dry mass, concentration in leaf and total accumulation of macro and micronutrients were determined, as well as the soil contents of exchangeable and non-exchangeable K. The K balance in the soil-plant system was also calculated. The increase of potassium fertilization resulted in a greater uptake of K, Ca and Mn but did not alter the total dry mass production of physic nut. The species can release and absorb K from the non-exchangeable soil fraction.

According to the practical requirements of marine scientific research and marine resources exploration, a marine geophysical information sharing platform was designed, configured and developed based on WebGIS technology using MapServer Open Source platform. The platform can provide convenient, efficient and interactive marine geophysical information sharing and visualization through internet or intranet in order to improve marine scientific data exchange and use. © 2010 IEEE.
