and < 50 ppb T-2. The data suggest that in piglets exposed to weaning stress and a natural infection with HPS, DON levels as low as 220 ppb can decrease performance. From day 15-20, all piglets were treated with Vital TSS (Trimethoprimum, Sufathiazolum and Sulfidimidinum). This treatment effectively controlled the HPS infection. During this trial phase no differences in performance were recorde...

Near-infrared reflectance spectroscopy (NIRS) analysis is based on the development of calibration equations that relate constituents and the infrared information spectrum. This study compares 2 chemometric tools for developing NIRS prediction models: the GLOBAL modified partial least squares and the recently calibration strategy known as LOCAL. The LOCAL procedure is designed to select, from a ...

The Andean páramo is notable for high soil carbon storage and its contribution to ecosystem services. However, the páramo’s ability maintain levels threatened by land use change from tussock grassland shrublands agricultural uses. A chronosequence study was conducted in around Quito, Ecuador, determine rate of loss traditional fallow agriculture. In parallel, a cover classification Landsat imag...

The conversion of native forests into pastures is still a common practice in Brazil. Abandoned have great potential for natural regeneration and therefore could play an important role meeting the enormous demand forest restoration. Few studies, however, investigated extent to which spatially-structured environmental variables community structure are correlated with variation species abundance r...

Biodiversity linked to traditionally managed semi-natural grasslands is declining, despite conservation efforts. At the same time, area of novel grassland habitats along linear infrastructure, such as road verges and power line corridors, increasing in some regions surpass grasslands. An open question what extent these can complement or even replace habitat for species. We compared alpha (speci...

Abstract Wood-pastures are semi-natural systems that combine a grazed grassland with tree layer. Shrubs often controlled, mostly to improve grazing potential, resulting in reduction of the available ecological niches. From conservation perspective, it is thus important identify management practices counter this reduction. Our overall objective was determine value small shrubby patches increase ...
