Vpliv hidrolizabilnih taninov na sestavo jajčne lupine in poškodbe grodnice pri kokoših nesnicah : magistrsko deloJavrnik, MonikaKakovost jajčne lupine je pomembna za potrošnike. Skozi poškodovano lupino lahko v jajčno vsebino vdrejo patogeni, ki povzročijo bolezensko stanje. Poškodbe grodnice kokoši nesnic so vedno pogostejše ... v različnih proizvodnih sistemih in veljajo za enega največjih problemov dobrega počutja. Namen poskusa je bil preučiti vpliv prehranskega dodatka, bogatega s hidrolizabilnimi tanini (HTBCO) v krmi kokoši nesnic na sestavo jajčne lupine in pojavnost poškodb grodnice. V poskusu smo imeli 36 kokoši nesnic, pasme prelux-G, dve skupini v šestih oddelkih po šest živali. V treh oddelkih smo nesnice krmili brez prehranskega dodatka, v treh pa z dodatkom. Vpliv dodatka smo opredelili z merjenjem debeline in mase jajčne lupine, vsebnosti kalcija, fosforja in magnezija v lupini, vsebnost vitamina D in holesterola v rumenjakih ter ocenili pojavnost poškodbe grodnice. Ugotovili smo, da dodatek značilno znižuje vsebnost kalcija v jajčni lupini (361 mg/g, p % 0,05) in holesterol v rumenjakih (1179 mg/100g, p % 0,05). Značilno pa se je zvišala vsebnost vitamin D3 v rumenjakih (0,52 %g/100g, p % 0,05).Type of material - master's thesis ; adult, seriousPublication and manufacture - Maribor : [M.
