 However, docking of lambs within 24 hours of birth is not recommended, as it may interfere with ingestion of colostrum and/or formation of the maternal bond.In the UK the law requires that docking on sheep using constriction methods must be performed within the first week of the animal's life.The UK Farm Animal Welfare Council has noted that this limitation can be problematic in management of hill flocks where normal practice is to handle lambs as little as possible during the first week "to avoid mis-mothering, mis-adventure and injury."
