The aim of the study is to examine the performance and carcass characteristics and some behavioral parameters of geese reared in the areas created by using some objects for environmental enrichment (EE) purpose. For this purpose, a total of 72 one-day-old goose goslings of both sexes were used. Geese were accommodated collectively for the first four weeks, then they were divided in three groups in 3 repetitions according to the EE applications and these were expressed as control (C), broom (B), and mirror (M). At the end of 14th week, live weight (LW), beak length (BL), wing length (WL), head diameter (HD), foot width (FW), body temperature (BT), warm carcass (WC), and cold carcass (CC) weights as well as warm and cold pH values (WpH&CpH), and tonic immobility duration (TID) of the groups were measured. Responses presented during the TI test were expressed as non-responses (NR), medium responses (MR), and high responses (HR). Among the groups, group M had the lowest value (110.08±10.69 s) in terms of TID (P > 0.05). Differences in terms of NR, MR, and HR were significant (P > 0.05). The differences between the groups were not statistically significant in terms of the other characteristics (P < 0.05). As a result, it was determined that geese reared by using the EE objects were affected by such environments, however, there were differences between the groups in terms of fear and stress parameters without having any negative effects on yield. |
