    Comparisons were made of the behaviour, physiology and meat quality of 24-week-old male veal calves (mean live weight 234 kg) that were slaughtered either at the veal unit (the control group) or following 3 h transportation at space allowances of either 0.7 or 0.95 m2 calf-1 and 1.5 h of lairage. Compared with nontransported calves, transported calves had a greater heart rate during the journey and during lairage; greater plasma cortisol concentration immediately after the journey, but not after 1.5 h of lairage; and greater plasma creatine kinase activity immediately after the journey and after 1.5 h of lairage. The transported calves did not lie down during the journey. There was no effect of space allowance on either the heart rate or frequency of potentially traumatic events during the journey or the plasma cortisol concentration and plasma creatine kinase activity sampled after the journey. There was no effect of transport on either carcase bruising or muscle pH 24 h after slaughter. Although compared with ‘on-farm’ slaughter, the transport and handling associated with the journey to the slaughterhouse were stressful to the calves; there were no adverse effects of transport on either carcase bruising or meat quality

    Estudaram-se o efeito do transporte e a mudança de local de manejo sobre a produção e a composição do leite e sobre as variĂĄveis fisiolĂłgicas, utilizando-se 12 cabras da raça Alpina em final de lactação. Semanalmente, foram mensuradas a produção e composição do leite e a contagem de cĂ©lulas somĂĄticas, alĂ©m do volume do leite residual apĂłs administração de ocitocina. Foram colhidas amostras de sangue para dosagem hormonal (cortisol) e enzimĂĄtica (glicose) no plasma no dia do transporte: antes (7h10min) e apĂłs (8h20min, 8h30min e 10h30min) o transporte. Nas trĂȘs semanas subsequentes ao transporte, tambĂ©m foram colhidas amostras de sangue Ă s 8h20min. Obtiveram-se teores mais elevados (P<0,05) de cortisol e glicose apĂłs o transporte e a mudança de local de manejo, e menor produção de leite (P<0,05) um dia apĂłs o evento. Porcentagem de gordura (P<0,05) e contagem de cĂ©lulas somĂĄticas apresentaram diferenças significativas (P<0,05) apĂłs o transporte. Os resultados permitem concluir que o transporte Ă© um agente estressor que pode, momentaneamente, influenciar a produção animal.<br>The effects of transportation and reallocation on milk production and composition and physiological responses were studied in 12 late-lactation Alpine goats. Weekly, somatic cell count, milk production and composition, and residual milk volume (after administration of oxytocin) were monitored. Blood samples were taken for hormonal (cortisol) and enzymatic dosages (glucose) in plasma on the day of transportation: before (7h10min) and after transportation (8h20min, 8h30min, and 10h30min). During the three weeks after transportation, blood samples were also taken at 8h20min. Higher levels (P<0.05) of cortisol and glucose after transportation and reallocation were observed and milk yield was significantly lower (P<0.05) one day after them. Milk fat percentage and somatic cell count (P<0.05) were higher after transportation. Results allow concluding that transportation is a stressor agent that may momentarily influence animal production

    The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities. The ILC has a total footprint of about 31 km and is designed for a peak luminosity of 2x10^34 cm^-2s^-1. This report is the Executive Summary (Volume I) of the four volume Reference Design Report. It gives an overview of the physics at the ILC, the accelerator design and value estimate, the detector concepts, and the next steps towards project realization.The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities.

    This report, Volume IV of the International Linear Collider Reference Design Report, describes the detectors which will record and measure the charged and neutral particles produced in the ILC's high energy e+e- collisions. The physics of the ILC, and the environment of the machine-detector interface, pose new challenges for detector design. Several conceptual designs for the detector promise the needed performance, and ongoing detector R&D is addressing the outstanding technological issues. Two such detectors, operating in push-pull mode, perfectly instrument the ILC interaction region, and access the full potential of ILC physics.This report, Volume IV of the International Linear Collider Reference Design Report, describes the detectors which will record and measure the charged and neutral particles produced in the ILC's high energy e+e- collisions.
