Vpliv talnega gretja na prirast in pojavnost poškodb nog brojlerskih piščancev [Elektronski vir] : diplomsko deloLevanič, MaticCilj raziskave je bil ugotoviti, ali ogrevanje hleva s talnim gretjem vpliva na prirast in pojavnost poškodb nog brojlerjev. V raziskavo smo vključili hlev s in hlev brez talnega gretja pri istem ... nastilju – lesnih oblancih. Meritve smo izvajali enkrat tedensko 35 dni. Pred poskusom smo si v obeh hlevih zamislili 6 merilnih mest v velikosti 4 m2, ki so skozi poskus ostala nespremenjena. Mesta so si bila med seboj ter od krmilnikov/napajalnikov isto oddaljena. V meritvah smo od brojlerjev pridobili podatke telesne mase in ocenili poškodbe nog. Zanimalo nas je tudi stanje v hlevu, zato smo beležili še temperaturo ozračja, nastilja ter delež vlage v zraku. Ugotovili smo, da pri povprečni doseženi masi med hlevoma ni statistično značilnih (P > 0,05) razlik, so se pa statistično značilne (P ≤ 0,05) razlike v telesni masi pojavile glede na teden reje. Po ocenitvi nastilja smo prišli do ugotovitve, da se hleva statistično značilno (P ≤ 0,05) razlikujeta pri dveh ocenah (ocena 1 in ocena 4). Povprečne temperature nastilja in ozračja v hlevih si med seboj niso bile statistično značilno (P > 0,05) različne, statistično značilne (P ≤ 0,05) razlike pa smo lahko beležili pri tedenskih meritvah. Povprečni odstotek vlage je bil po zaključku poskusa višji v starejšem hlevu, med hlevoma pa le v enem tednu reje ni bilo statistično značilnih (P > 0,05) razlik. V vseh tednih reje se pri obeh hlevih prisotnost poškodb nog ni zaznala.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Maribor : [M.
