مستخلص: Agonistic behavior is a problem of animal welfare in commercial turkey fattening. In this study, possible influences of the barn layout and the climate of the barn on the behavior of fattening turkeys on a commercial farm were investigated. The study was conducted on a turkey farm with two comparable barns. A modified ventilation system was installed in the trial barn to improve the removal of NH3 and CO2. The drinkers were rearranged to increase the animals' free floor area. In each barn, 3600 male turkeys (B.U.T. 6) were housed. Videos were recorded continuously from housing until removal for three consecutive fattening periods. NH3 and CO2 values were recorded. Turkeys showed increased activity (p < 0.001) and comfort behavior in the trial barn during late fattening (p = 0.002). Agonistic behavior increased during late fattening, particularly around the drinkers (p < 0.001). NH3 levels differed at the beginning of fattening. The study shows that extending the resting area contributes to increased activity and comfort behavior. The rearrangement of drinkers showed no positive effects on agonistic behavior, as the distance between individual drinkers was too small. Due to behavioral differences being most evident in late fattening, no conclusions can be drawn concerning the influence of CO2 and NH3. [ABSTRACT FROM AUTHOR]
