Abstract:	Cilj raziskave je ugotoviti ali uporaba apna preprečuje pojav salmonele v hlevih za rejo piščancev. Raziskavo smo opravili na perutninskih farmah, kjer smo v enem hlevu (testni hlev) pobelili tla in stene z apneno brozgo in na koncu celoten hlev zameglili z razkužilom Fumagri HA; drugi hlev (kontrolni hlev) pa smo pripravili po navodilih iz priročnika za rejo brojlerjev. Kontrolna vzorčenja smo opravljali po odstranjevanju gnoja, po pranju hleva, po razkuževanju + beljenju, po plinjenju, ter na 0. dan, 7. dan, 14. dan, 21. dan, 28. dan in 35. dan reje. Vzorce so analizirali v laboratoriju NVI po metodi ISO 6579-1:2017. V raziskavi smo opravili 3 ponovitve v istih hlevih. Pojavnost pozitivnih vzorcev smo analizirali s statističnim paketom SPSS 28.1 z uporabo 2 testa. Ugotovili smo, da v fazi razkuževanja ni statistično značilnih (P ≥ 0,05) razlik, v fazi razkuževanje + beljenje smo ugotovili statistično značilno (P ≤ 0,05) razliko med testnim in kontrolnim hlevom, kjer nismo zaznali pojav salmonele. V proizvodni fazi se statistično značilna (P ≤ 0,05) razlika pojavi med hlevoma v 14. dnevu reje, kjer je v testnem hlevu manjša pojavnost salmonele. Pri vzorcih odvzetih s tal in sten ni statistično značilnih (P ≥ 0,05) razlik med hlevoma, saj v fazi razkuževanje + beljenje, plinjenje in 0. dan nismo zaznali pojav salmonele v testnem hlevu. V 35. dnevu reje se pojavi statistično značilna (P ≤ 0,05) razlika med hlevoma, kjer v testnem hlevu nismo zaznali pojava salmonele. Rezultati analiz vzorcev iz krmilnikov, napajalnikov, loput so pokazali, da v fazi razkuževanja ni statistično značilnih (P ≥ 0,05) razlik, saj v fazi razkuževanje + beljenje ni bilo pojava salmonele v testnem hlevu. V proizvodni fazi pa se hleva statistično značilno (P ≤ 0,05) razlikujeta v 14. in 21. dnevu reje, kjer smo zaznali več pozitivnih vzorcev na salmonelo v kontrolnem hlevu.

Title:	Use of quicklime for the prevention of salmonella infantis in poultry stables
Abstract:	The aim of the research was to confirm that the use of lime prevents the occurrence of salmonella in chicken barns. The research was carried out on a poultry farms, where in one barn (test barn) the floors and walls were whitewashed using lime slurry, and at the end of this procedure the entire barn was fogged with the Fumagri HA disinfectant, while the other barn (control barn) was prepared according to the instructions of the from the Broiler Breeding Manual. Control sampling was performed after remuval manure, after washing the barn, after disinfection and bleaching, after fumigation, on day 0, day 7, day 14, day 21, day 28 and day 35 of rearing. The samples were analyzed in an NVI laboratory according to the ISO 6579-1:2017 method. The occurrence of positive samples was analyzed with the SPSS 28.1 statistical package using the 2 test. 3 repetitions were performed in the same barn. We found that there are no statistically significant (P ≥ 0.05) differences in the disinfection phase, except in the disinfection and bleaching phase, there is a statistically significant (P ≤ 0.05) difference between the test barn, where we did not detect the occurrence of salmonella, and the control barn. In the production phase, a statistically significant (P ≤ 0.05) difference appeared between the barns on the 14th day of rearing, where the incidence of salmonella was lower in the test barn. There were no statistically significant (P ≥ 0.05) differences between the two barns in the floor and wall samples, although we did not detect the occurrence of salmonella in the test barn during the disinfection and bleaching, gassing and day 0 phases. On the 35th day of rearing, a statistically significant (P ≤ 0.05) difference between the two barns appeared, where we did not detect the occurrence of salmonella in the test barn. The results of the sample analyses from feeders and hatches showed that there were no statistically significant (P ≥ 0.05) differences in the disinfection phase, although there was no salmonella occurrence in the test barn during the disinfection and bleaching phase. In the production phase, the barns differed statistically significantly (P ≤ 0.05) on the 14th and 21st day of rearing, where more positive samples for salmonella were detected in the control barn.
