Abstract		The subject of this research was the influence of added bioenzymatic and mineral additivs on air quality, on quality of bedding and on production results in turkey breeding. The comparison of the control building with the test buildings showed that the addition of the bioenzymatic and mineral additive to bedding influenced both the quality of air and bedding. In the building in which the bioenzymatic additive was added to bedding, a 12.00 % drop in ammonia release from bedding was registered. It was also found that the added bioenzymatic additive influences the quality of bedding. The temperature of the bedding grew by 7.27 %, the total nitrogen in the bedding fell on average by 32.17 %, while the nitrogen in dry substance was lowered by 23.88 %. The pH of the bedding was on average 4.77 % higher than in the control building. In the building with the added mineral additive, the ammonia from the bedding was reduced by 17.27 %. The adding of mineral additive also influenced the features of the bedding. Its temperature increased by 6.29 %, the share of total nitrogen in the bedding went down by 23.98 % and the share of nitrogen in dry substance by 15.52 %. The pH of the bedding was on average 2.77 % higher. The largest influence on the emission of ammonia from bedding is exerted by the share of dry substance and nitrogen in the bedding. The influence of both parameters was highest in the control building while, in the building with mineral additive, it was hardly perceptible. By adding the bioenzymatic additive to bedding more frequently, one could achieve a larger drop in ammonia and unpleasant odour emissions. As far as the building with the added mineral additive is concerned, the non-established influences of dry substance and nitrogen in the bedding on ammonia emissions and unpleasant odours lead to the conclusion that the intervals of adding as well as the amount of the used additive were optimal.
Summary		Raziskan je bil vpliv dodajanja bioencimskega in mineralnega dodatka na kakovost zraka in nastila ter na proizvodne rezultate pri vzreji puranov. Ob primerjanju kontrolnega hleva s testnima je bilo ugotovljeno, da dodajanje omenjenih dodatkov nastilu vpliva na kakovost zraka in nastila. V hlevu z bioencimskim dodatkom je bilo ugotovljeno za 12,00 % manjše sproščanje amoniaka iz nastila. Prav tako je bil ugotovljen vpliv bioencimskega dodatka na kakovost nastila: njegova temperatura se je zvišala za 7,27 %, skupni dušik v nastilu se je povprečno zmanjšal za 32,17 %, pH nastila pa je bil v povprečju višji za 4,77 %, vse v primerjavi s kontrolnim hlevom. V hlevu z dodanim mineralnim dodatkom se je po ugotovitvah zmanj*ala količina amoniaka v zraku za 17,27 %. Tudi dodajanje mineralnega dodatka je vplivalo na lastnosti nastila: temperatura nastila je bila višja za 6,29 %, vsebnost skupnega dušika pa se je zmanjšala za 23,98 %. Kislost nastila je bila v povprečju večja za 2,77 %. Na emisije amoniaka v nastilu najbolj vpliva vsebnost suhe snovi in dušika. Na osnovi statistične obdelave je bilo ugotavljeno, da je vpliv obeh sestavin na izločanje amoniaka največji v kontrolnem hlevu, v hlevu z dodatki v nastilu pa je vpliv vsebnosti suhe snovi in dušika zmanjšan, zaradi česar se je zmanjšala količina amoniaka v zraku.
