| Popis: | Aspects related to good handling practices have significant impacts on animal behaviour with positive effects on the productivity and profitability of production systems. This study investigated the impact of good handling practices on the modification of stress indicators and the behaviour of beef cattle. Thirty-six male castrated bovines at the growth stage were evaluated for 490 days and submitted to two different production systems in Southern Brazil: good handling practices (GHP) and a traditional handling system of beef-cattle farming (THS). Body weight, reactivity indicators (flight distance and composite behaviour score), and blood indicators of stress (glucose and cortisol) were measured. An analysis of variance was carried out with measurements repeated over time, and Pearson's correlation applied between the variables mentioned above. No differences were found (P>0.05) for body weight in any of the evaluations, with initial weights of 196.2 and 196.3 kg and final weights of 431.0 and 413.8 kg for the GHP and THS steers, respectively. The GHP determined better values for the stress and behavioural indicators compared to THS (P |
