Abstract The simple extrapolation of management used successfi.illy for the control and handling of sheep in temperate climates to goats does not always work because they are separate species and show very different behavioural pattern in many areas. Here below the effect of some managerial practices applied for goat on the behavioural traits, blood serum cortisol and productive traits of goats are summarized in three experiment as follows. Experiment I: Four group of Baladi kids (n4 each) were castrated at 3.5-4 months of age by either surgery, crushing by a Burdizzo or rubber ring methods. Responses of castrated kids were compared to a control group. Blood serum cortisol was estimated in blood samples taken during the first 3 h after castration. Behavioural observations were performed for 6 weeks after treatment, accompanied by weekly weighing of the animals and the obtained results were as follows: 1. The behavioural response to surgical and Burdizzo castration was significantly decreaseed the feeding (21.542±1.291 and 24.563±1.316 mm/h), and standing times (27.854±1.302 and 32.167+1.41 1mm/h), also the frequency of walking (3.525±0.434 and 4.825±0.477), scratching (3.225±0.434 and 3.525±0.490) and rubbing (0.525±0.157 and 0.950±0.218) were increased, moreover, the sternal (23.396±1.331 and 21.417±1.355 mm/h) and lateral lying time (4.333±0.678 and 1.583±0.449 mth/h) were also increrased. 2. During the 6th weeks after surgical castration there was an increase in the kids’ concern with the site of castration, indicated by a significantly (P<0.0 1) increase of the incidence of tail wagging (1.525±0.287) which was associated with pawing (0.600±0.232). |
