Aiming at developing a tool for assessing the magnitude of farm animal health, an indicator named herd “animal health status” was built. To illustrate the construction of the indicator, serum samples were taken from 923 goats on 17 goat farms in the state of Sao Paulo, Brazil, where three diseases were evaluated along with their impact percentages: caprine arthritis encephalitis, toxoplasmosis and neosporose – all of an infectious and transmissible nature and the cause of considerable economic losses. The mathematical rationale underlying the building of the “animal health status” indicator ranks properties on a 0 - 100% scale in terms of disease positivity in the herd, with the lowest indicator value indicating the highest cumulative disease frequency (0% = all animals tested positive for the three diseases, 100% = all animals tested negative for all diseases). Anti-T. gondii, anti-N. caninum and anti-CAEV antibodies were tested using indirect immunofluorescence reaction (IIFR ≥ 16), Neospora agglutination test (NAT ≥ 25) and agarose gel immunodiffusion (AGID positive or negative), respectively. The animal health status of the farms ranged from 32.38% to 96.40% according to disease positivity. The animal health status value will have a direct reflection on the production chain both on and off the farm, providing not only great market advantages, due to how the expression of animal health will add value to livestock farms, as well as on the consumer who can check the quality of animal health at the beginning of the production chain.

Protocols for rapid habitat evaluation and the biotic indices used in biomonitoring of streams in Brazil provide useful information about water quality and modifications in the ecosystem. However, the interpretation of their results is limited. Previous studies pointed out the low sensitivity of those indices to measure the quality of low-order streams, since they only measure organic impacts. Environmental degradation of these streams is mainly related to impacts caused by landscape change, such as erosion, siltation, channel change, loss of riparian vegetation, and reduction in water flow. The streams of the Serra do Japi are under some of these impacts, caused by agricultural activities. In this study, we evaluated whether the reduction of natural characteristics in these environments would decrease water quality. The Protocol of Habitat Diversity was affected by the impacts of agricultural activities. However, the other three biotic indices: Biological Monitoring Working Party Score System, Average Score Per Taxon, and Index of Benthic Community were not as sensitive to those impacts, since they all indicated a high water quality. An adaptation of the attributes and the scoring system is suggested for defining better policies for the conservation of this area.

Time series tendencies are an important tool for different sectors such as the scientific community, industries and environmental protection agencies who can evaluate the variability of a specific parameter in time, what is very important piece of information for establishing corrective and preventive actions. This work presents a time series model of main physical, chemical and biological parameters of the Water Quality Index (WQI) determined for different selected points of a hydrographical basin form May/2006 to Aug/2010. The statistical model Arima enabled a better understanding of the physical, chemical and biological processes that most clearly influences WQI. The Arima model allowed the assessment of the trend of several parameters used in the calculation of the WQI, showing that dissolved oxygen, turbidity, total nitrogen, and fecal E. coli were highly correlated and are the parameters that caused the index changes over time.

Two experiments were conducted in order to study the effects of seed number, temperature and time of soaking sesame seeds on the results of the electrical conductivity test for physiological quality of seeds. In the experiment I evaluated the electrical conductivity varying the number of seeds (25, 50 and 100) and temperature (20, 25 and 30° C) in experiment II is different soaking periods (2, 4, 6, 8, 12, 16, 20 and 24 h). The tests were performed with three cultivars (cv. Trebol, cv. Cnpa G4 e cv. Comum). The treatments in factorial 3x3x3 and 3x8 in experiments I and II, respectively. The experimental design was completely randomized, with four replications. Means were compared by Tukey test at 5% probability. The characterization of cultivars held through the germination and vigor tests (physical, physiological and biochemical), which rated the Trebol cultivar seeds with better physiological then the Cnpa G4 and Comum. The electrical conductivity test was conducted with four sub-samples of 25 pure seeds soaked in 75 mL of deionized water at 25° C, to separate the lots from 2 hours of soaking, being feasible to evaluate the quality sesame seeds.
