The 12-km2 Ribeirão das Posses Watershed (RPW), which is dominated by Ultisols and Inceptisols, is located in the south of Minas Gerais, Brazil. RPW discharges into the Jaguarí River, one of the most contributing rivers to supply the São Paulo metropolitan area. Over the last century in this watershed, the land use changed from native forests to more homogeneous vegetation for pastures, crops and forest plantations of eucalyptus, which have cumulative impacts on water yield and quality. To address this, a public policy was adopted establishing the Payment for Environmental Services covering three small watersheds of this river basin, including RPW. Since 2004, under such initiative, some small areas with vegetation of native species have been planted, especially in riparian zones, around springs, and at hilltop positions. Also some soil management has been conducted using small dams over the steep slopes and readjusting lines of cultivations to level counters. Therefore it is expected that water and soil ecosystems services will recover over time. The present work compares a streamwater quality monitoring conducted in 2017-2018 to the streamwater chemistry results obtained by other previous studies conducted from 2011 to 2016 in RPW. The main hydrobiogeochemical parameters evaluated here were: flow, temperature, pH, electrical conductivity, dissolved oxygen, carbon, nitrogen and major dissolved ionic elements as well as suspended particulate matter. The results express how it is important that the stream sampling schedule cover rainy periods, which was possible using an automatic water sampler. Overall only a very small increase in water quality parameters was detected. The same was concluded for stream discharge, which depended primarily on the rainfall over the studied years. In the future, it would be interesting to compare the loss of sediments and nutrients from soils during the larger rainfall events, and how this can be accentuated if the changing climate confirms the increase of such events along with the amplification of dry periods. It is important to be aware that the ecosystem services provided by water in fact derived in part from good soil management, in a way that soil provides many ecosystem services, together with water by providing food, water filtration, regulating nutrient cycling, and other essential goods for life. In fact soil processes and functions are fundamental to assess ecosystem services and the effects of land use on them.

Abstract: This study evaluated the effects of isolated or combined prebiotics blended with sodium butyrate and zinc proteinate on performance, intestinal morphometry, and expression of genes associated with nutrient transport and immune response in broilers. 1,400 birds were randomly assigned to 5 treatments (Negative control (NC) without antibiotic; Positive control (PC) with antibiotic; Prebiotic (Prebio) composed of mannan fractions; Blend, composed of sodium butyrate, hydrolysed yeast cell wall and zinc proteinate; and the combination Prebio + Blend), with eight replications and 35 birds per experimental unit. The PC led to higher weight gain (WG) and lowered feed conversion (FCR) from 1 to 7 days of life than the other treatments. The use of prebio and blend resulted in high WG from 22 to 42 days (1773; 1768.9 g, respectively). However, the combination of prebio + blend was similar to PC and NC treatments. The additives resulted in longer duodenal villi when administered alone and in ileal villi (p = 0.001) combined, with no effect on jejunal villi. Crypt depth and duodenal villus: crypt ratio was higher for both additives types. A significant difference among treatments in the expression of the sodium-dependent glucose transporter gene (SGLT1) was noted, with greater expression in birds that received NC. There was higher expression of the neutral and cationic amino acid transporter gene (y + LAT-2) with the prebio and blend, either alone or in combination. The prebio blend with sodium butyrate and zinc proteinate additives used separately in broiler diets supported beneficial changes in intestinal morphometry, nutrient absorption, and performance, indicating their value in antibiotic-free broiler production systems.
