Incorporação de probióticos na dieta para juvenis de tilápias-do-nilo: Parâmetros hematológicos, imunológicos e microbiológicos

Probiotics are generally considered as live microorganisms which, when administered in adequate amounts, confer a health benefit to the host. The processing method of diet and the form of inclusion of probiotic can interfere in hematological, immunological and microbiological parameters in fish. The aim was to estimate the hematological, immunological and microbiological parameters in juveniles of Nile tilapia, fed probiotic, included before and after the process of pelletization and extrusion. The experimental design was completely randomized, with five treatments: pelleted diet without probiotic, pelleted diet with inclusion of probiotic before and after processing, extruded feed without probiotic and extruded feed with inclusion of probiotic after processing and five replications. Two hundred and fifty fish were distributed in 25 aquaria (20 L) and fed for 63 days. The blood composition (red and white) showed no significant differences except mean corpuscular hemoglobin concentration of control when compared to other treatments. The phagocytic capacity of the animals that had received the extruded diet supplemented with probiotic was significantly higher when compared to the other treatments. However, there were no differences between the treatments regarding to the phagocytic index. Fish fed the extruded diet exhibited significant improvement in the nonspecific immunity. The probiotic bacteria colonized the intestine, since it was possible to recover them. We can affirm that these fishes remained healthy, because the hematological parameters were not altered during the experimental. The study shows that any form type of inclusion in the feed tested (before or after and after pelletizing extrusion) may be easily used by the fish farmer.

Suscetibilidade magnética do solo e estimação da capacidade de suporte à aplicação de vinhaça

The objective of this work was to evaluate the magnetic susceptibility efficiency for estimating the support capacity of areas for vinasse application. Two hundred forty-one soil samples were collected from a 380-ha area, on which soil chemical properties, clay content, and magnetic susceptibility were determined. Vinasse requirement was calculated for each sample. Data were subjected to descriptive statistical analysis, and regression models were developed between magnetic susceptibility and the other evaluated attributes. The analysis of data spatial dependence was performed using geostatistics. Kriging maps and cross variograms were built in order to investigate the spatial correlation between soil magnetic susceptibility and studied attributes. Based on the map of vinasse requirement, on the soil classes, and on the kriging map, calculations were done for average vinasse dose and average soil support capacity, weighted by the area. Magnetic susceptibility has significant linear spatial correlation with recommended vinasse doses and soil support capacity for the application of this effluent, and it can be used as a pedotransfer function for indirect quantification of soil support capacity.
