Abstract:Namen diplomskega dela je ugotoviti vpliv rastlinskih ekstraktov Sapotan powder in Yucca biopowder v reji pitovnih piščancev, na proizvodnost, konverzijo krme, indeks notranjih organov in vezavo NH3 v nastilju. Dnevno smo spremljali količine zaužite krme in vode, merili koncentracije plinov z merilcem Dräger in ocenjevali kakovost nastilja. Tedensko smo beležili maso piščancev in jemali vzorce izločkov. Ob zakolu smo pri treh povprečnih petelinih in treh povprečnih jarkicah v posamezni skupini stehtali očiščen trup, njihove notranje organe (srce, jetra, mlinček, ledvico) in izmerili dolžino tankega črevesja, ter dolžino slepih čreves. Ugotovili smo naslednje, da rastlinski ekstrakti statistično značilno ne vplivajo na ekonomsko pomembne parametre med katere spadajo konzumacija, konverzija in klavni izplen (P > 0,05). Rastlinski ekstrakti nimajo statistično značilnega vpliva na vse notranje organe in dolžino črevesja. Njihov vpliv se statistično značilno izraža v masi jeter pri kateri je signifikantna (P ≤ 0,05) razlika med KONTROLO (39,92 g) ter YUCCA (41,25 g) v primerjav s SAPOTAN I (52,08 g). Ter v masi pankreasa, kjer je statistično (P ≤ 0,05) značilna razlika med SAPOTAN I (3,58 g) in SAPOTAN II (4,42 g). Prav tako smo v poskusu ugotovili, da rastlinski ekstrakti vplivajo na zmanjšanje emisije NH3 v reji pitovnih piščancev, ter da so signifikantne razlike med SAPOTAN II (6,32 ppm) ter YUCCA (6,08 ppm) v primerjavi s KONTROLO (9,17 ppm).

Title:Plant extract usage for reducing nh3 formation in chicken farming
Abstract:The purpose of the thesis was to determine the influence of plant extracts Sapotan powder and Yucca biopowder in broiler chicken, namely their influence on production, feed conversion, internal organ index and reduction of NH3 binding in the litter. We monitored the amount of feed and water consumed daily, measuring the gas concentration with a Dräger meter, and monitoring the quality of the bedding. Weekly tasks included weighing the chickens and taking samples of their excretions. The cleaned carcass, their internal organs: heart, liver, pancreas, kidney and measured the length of the small intestine and the length of the caecum of three average roosters and three average hens in each group were weighed at slaughter. We found that plant extracts do not have a statistically significant effect on economically important parameters including consumption, conversion and slaughter yield (P > 0,05). Plant extracts do not have a statistically significant effect on al internal organs and intestinal lenght. Their influence is statistically significant (P ≤ 0,05) in liver mass, where there is a significant difference between CONTROL (39,92 g) and YUCCA (41,25 g) compared to SAPOTAN I (52,08 g). And in pancreas mass, where there is a statistically significant (P ≤ 0,05) difference between SAPOTAN I (3,58 g) and SAPOTAN II (4,42 g). We also found in the experiment that plant extracts affect the reduction of NH3 emissions in broiler chicken farming, here there were significant differences between SAPOTAN II (6,32 ppm) and YUCCA (6,08 ppm) compared to CONTROL (9,17 ppm).
