Environmental enrichment of some behaviour the broiler, effects of growth and carcass characteristics and blood parameters

In this study, environmental enrichment in broiler live weight, feed intake, rectal temperature, fear behavior (Tonic Immobility), aimed to determine the effect of some blood parameters walk score. In the study, 280 one-day-old broiler chicks were used in. Weekly live weight, feed intake and feed conversion ratio determined, 3 and 6 weeks in tonic immobility (TI) test done, rectal temperatures are determined. In the same period, liver, spleen and bursa fabricius weights were determined. In week six of the experiment it analyzed the results of the analysis obtained from blood samples taken from all groups. In addition, attempts were made to walk the 6 week test scores. Trial of the control group after 42 days higher than the average live weight was found that the treatment group, but not statistically significant (P>0.05). The rate of feed of the treatment groups was found to be better than the control group. Trial of 21 and 42 days in the lymphoid organs and in terms of the weight of slaughtered chicken rectal temperatures observed no statistically difference (P> 0.05). At the end of the experiment, the tonic immobility of the control group and the treatment group walks important scores (P<0.05) were observed to be high level. As a result, environmental enrichment, we can say that without affecting performance by reducing fear and stress increase animal welfare.
