Na przestrzeni ostatnich lat mikropożyczki udzielane małym i średnim przedsiębiorstwom nabrały większego znaczenia w wielu krajach środkowej i wschodniej Europy. Jednakże mało jest jak dotąd empirycznych dowodow dotyczących skutków gospodarczych i społecznych mikrofinansowania. Probując rzucić więcej światła na tę ważną kwestię, niniejsza publikacja opiera się na konkretnym studium przypadku, poddając analizie ekonomiczne skutki wprowadzenia w życie programu mikropożyczek przez łotewski bank rozwoju Hipoteku Banka1. Autorzy przeanalizowali dane dostarczone przez Hipoteku Banka oraz dla porównania posłużyli się wskaźnikami ekonomicznymi dla Łotwy i jej poszczególnych regionów. Ustalono, że średnio w firmach, którym powyższy bank udzielił pożyczki, znacząco wzrósł poziom zatrudnienia w okresie pożyczki. Ponadto, pośród klientów banku przeprowadzono badanie kwestionariuszowe. Jego wyniki wskazują na to, że program mikropożyczek zdecydowanie przyczynił się do wsparcia istniejących firm, jak również do założenia nowych firm, aczkolwiek wpływ mikropożyczek jest rożny, zależnie od branży, w której prowadzona jest działalność gospodarcza.

Selenium (Se) is involved in several biological functions and its supplementation is necessary for farm animals. Se can be provided in organic or inorganic forms, which are metabolized differently. The aim of this study was to compare the effects of switching the Se source in the last 60 days of fattening on beef quality and Se content in meat. Charolaise beef heifers supplemented since the beginning of the fattening period with sodium selenite (162 heads; 517 ± 61 days of age) were divided into two groups, fed the same diet, in which Se (0.2 mg Se · kg–1 DM of feed) was provided as sodium selenite (SS; 82 heads, 450.7 ± 33.7 kg body weight – BW) or selenium-enriched yeast (Se-Y; 80 heads, 454.6 ± 41.7 kg BW). The Se source did not affect growth performance, meat centesimal composition, thawing loss, cooking or drip losses, and pH during 8 days of aerobic storage. Se-Y supplementation improved the meat Se content (P < 0.001) and tended to reduce shear force (P = 0.076) at 48 h post mortem. Lightness (P < 0.01) and yellowness (P < 0.01) decreased with the duration of storage and were higher in the Se-Y group compared with the SS group during 8 days of storage. Meat from group Se-Y also showed a better visual score for colour (P < 0.01), odour (P < 0.05), surface wetness (P < 0.05) and overall appearance (P < 0.01). Under the given experimental conditions, switching beef heifers from inorganic to organic Se in the last two months of fattening improved meat tenderness, shelf life, colour stability and muscle Se content.

The effects of dietary supplementation with selenium enriched yeast on growth, immune and antioxidant status were assessed on 228 newly received beef cattle. During the adaptation phase (54 days), the animals were housed in 38 pens (19 pens per treatment) and supplemented with 0.32 mg · kg−1 DM of Se as sodium selenite (CTR) or selenium enriched yeast (SeY). At days 0, 19 and 54 the animals were weighed and blood samples were collected from one healthy animal per pen. During the experimental trial, bovine respiratory disease (BRD) occurrence was monitored. Blood antioxidant status, selenium serum concentration, bovine herpesvirus-1 (BHV-1) antibody titer and serum bactericidal activity were determined. Growth performance was improved (P < 0.05) and BRD occurrence was reduced (P = 0.06) in SeY group. SeY supplementation increased BHV-1 antibody titre after vaccination, highlighting a positive impact of SeY supplementation on immune system functioning. SeY supplementation improved (P < 0.01) selenium serum concentration and positively affected antioxidant status, expressed as Kit Radicaux Libres value, that tended to be higher (P = 0.07) in SeY group, due to Se higher bioavailability. The obtained results suggest that dietary supplementation with organic form of selenium improves growth performance, immune and antioxidant status in newly received beef cattle
