    The Scientific Opinion on the welfare of animals during transport reviewed the most recent scientific information concerning the main farm species. New scientific evidence and consequent conclusions and recommendations were arranged following the structure of Annex I of EC Regulation 1/2005 . On fitness for transport, recommendations for cattle and poultry were focused on repeated humane handling and careful inspection prior to transport. On the means of transport, use of partitions in horse transport, compulsory fasting of pigs with provision of water at stops, and temperature limits for poultry were major recommendations. Maintaining stability of animal groups was recommended as good practice, with special emphasis on the need to avoid mixing unfamiliar pigs or goats. On watering and feeding intervals, journey times and resting periods, journey duration should not exceed 12 hours for horses and 29 hours for cattle. Horses should be supplied with water one hour before and one hour after transport, and for cattle there should be a 24 hour recovery period with access to food and water. For rabbits, time spent inside the containers during lairage should be considered journey time. Space allowance for horses should be given in terms of kg/m2 instead of m2/animal. For cattle and sheep, it is recommended that space allowances should be calculated according to an allometric equation relating size to body weight. Limits for stocking densities of broilers in containers should be related to thermal conditions. On the navigation systems, temperature monitoring systems should be incorporated. Minimum standards should be established regarding data type to be recorded, the system and the on‐board architecture. Recommendations for further research focused on the thermal limits and regulation for poultry and rabbits, the effects of ventilation on pigs, space allowance for rabbits, newly hatched chicks and pigs, optimal journey times for horses, pigs and calves

    Vaccination of poultry against highly pathogenic avian influenza: Part 2. Surveillance and mitigation measures

    Selecting appropriate diagnostic methods that take account of the type of vaccine used is important when implementing a vaccination programme against highly pathogenic avian influenza (HPAI). If vaccination is effective, a decreased viral load is expected in the samples used for diagnosis, making molecular methods with high sensitivity the best choice. Although serological methods can be reasonably sensitive, they may produce results that are difficult to interpret. In addition to routine molecular monitoring, it is recommended to conduct viral isolation, genetic sequencing and phenotypic characterisation of any HPAI virus detected in vaccinated flocks to detect escape mutants early. Following emergency vaccination, various surveillance options based on virological testing of dead birds ('bucket sampling') at defined intervals were assessed to be effective for early detection of HPAIV and prove disease freedom in vaccinated populations. For ducks, virological or serological testing of live birds was assessed as an effective strategy. This surveillance could be also applied in the peri-vaccination zone on vaccinated establishments, while maintaining passive surveillance in unvaccinated chicken layers and turkeys, and weekly bucket sampling in unvaccinated ducks. To demonstrate disease freedom with > 99% confidence and to detect HPAI virus sufficiently early following preventive vaccination, monthly virological testing of all dead birds up to 15 per flock, coupled with passive surveillance in both vaccinated and unvaccinated flocks, is recommended. Reducing the sampling intervals increases the sensitivity of early detection up to 100%. To enable the safe movement of vaccinated poultry during emergency vaccination, laboratory examinations in the 72 h prior to the movement can be considered as a risk mitigation measure, in addition to clinical inspection; sampling results from existing surveillance activities carried out in these 72 h could be used. In this Opinion, several schemes are recommended to enable the safe movement of vaccinated poultry following preventive vaccination
