Abstract:Cilj raziskave je bil ugotoviti, ali si piščanci znajo izbrati bolj primeren nastilj in kako posamezen nastilj vpliva na pojavnost nožnega dermatitisa v posameznem obdobju leta. V raziskavo smo vključili tri vrste nastilja: hoblovino (H), peletirano slamo (PS) in rezano slamo (RS). Živali so bile razporejene v 6 skupin, posamezno skupino smo opazovali dnevno 42 dni, povprečno število živali v je bilo 11800. Piščanci so bili prosto naseljeni po celotnem hlevu, ki je bil razdeljen na tri dele. Vsak del je imel drug nastilj, med posameznimi deli pa ni bilo pregrad. Ko je bil hlev izpraznjen in pripravljen za novo rejo, smo na vsaki tretjini zamenjali nastilj. Na vsakem nastilju smo namestili 6 opazovalnih mest, velikosti 1 m2. Ugotovili smo, da v doseženi masi na izbranem nastilju ni statistično značilnih (P > 0,05) razlik ob kontrolnih tehtanjih, tudi med rejami nismo ugotovili statistično značilnih (P > 0,05) razlik v doseženi masi živali. Pri izbiri nastilja smo ugotovili, da se hoblovina in peletirana slama statistično značilno (P ≤ 0,05) razlikujeta od rezane slame, saj je bilo na rezani slami statistično manj piščancev. Med rejami v posameznem tednu pa smo ugotovili statistično značilno (P > 0,05) razliko. Na hoblovini in peletirani slami smo ugotovili manj poškodb nožnih blazinic kot na rezani slami. Ugotovili smo tudi, da je bilo največ poškodb nog v zimskem obdobju. Odsotnost poškodb je bila največja na hoblovini in peletirani slami.

Title:Litter type and the occurrence of dermatitis in broiler chickens bred under bts breeding conditions
Abstract:The goal of this research was to find out, if the chickens are capable to choosing appropriate litter and how the certain litter effects on their health in different season, in this case, on the occurrence of foot dermatitis. 3 different types of litter were included in this research: wood shaving (H), straw pellets (PS) and cut straw (RS). The observed chickens were divided into 6 groups. We observed one group daily for 42 days where the, average size was about 11800 animals. The chickens were settled across the whole barn, which was divided into three sections. Every section had different litter and there were no barriers between sections. When the barn was depleted and prepared for a new group, the litter in all the sections was changed. In each section, there were 6 observation places in the size of one square meter. There was no statistical significant difference (P > 0.05) in achieved weight at the control weighing among different litters. Also, there were no statistical significant differences (P > 0.05) in the live weight between the groups of chickens, respectively. Concerning the choice of litter, there were some statistical significant differences (P ≤ 0.05). Wood shaving and straw pellets were more settled with chickens than cut straw. There was also statistically significant difference (P > 0.05) in the weekly observation of a group for feet injuries. There were less FPD on wood shaving and straw pellets than on cut straw. The highest number of injuries appeared in winter time. The highest absence of injuries was on wood shaving and straw pellets.
