更新了以前的意见“用于牛肉生产的牛的福利”（SCAHAW，2001年）和“集约化小牛养殖系统中福利不良的风险”（EFSA，2006年）中提供的信息，并审查了有关主题的最新科学证据。使用结构化分析确定福利差的风险，并审查SCAHAW（2001）牛肉意见中未确定的问题，特别是住房和管理对肠道和呼吸道疾病的影响。该意见涵盖了牛肉生产的所有系统，尽管没有考虑乳牛或繁殖公牛的福利。关于肉牛的一章提出了新的证据和建议，涉及热和冷应激、断肢和疼痛管理、与高精饲料有关的消化系统疾病以及与过度饲养、通风不足、动物混养和早期诊断和治疗失败有关的呼吸系统疾病。如风险评估所确定的，为牛肉生产而饲养的牛的主要福利问题是与过度放养、通风不足、牲畜混养和早期诊断和治疗失败有关的呼吸道疾病，与密集精料喂养有关的消化系统疾病，饮食中缺乏对身体有效的纤维，以及与饲养场面积不足和混养有关的行为障碍。白色小牛犊的主要危险被认为是缺铁性贫血，这是膳食铁限制的直接后果，与液体饲料摄入量高和身体有效纤维摄入量不足有关的肠道疾病，与地板和地板空间不足有关的不适和行为障碍。(C)欧洲食品安全局，2012年。
Information given in previous Opinions "Welfare of cattle kept for beef production" (SCAHAW, 2001) and "The risks of poor welfare in intensive calf farming systems" (EFSA, 2006) is updated and recent scientific evidence on the topics reviewed. Risks of poor welfare are identified using a structured analysis, and issues not identified in the SCAHAW (2001) beef Opinion, especially effects of housing and management on enteric and respiratory diseases are reviewed. The Opinion covers all systems of beef production, although the welfare of suckler cows or breeding bulls is not considered. The Chapter on beef cattle presents new evidence and recommendations in relation to heat and cold stress, mutilations and pain management, digestive disorders linked to high concentrate feeds and respiratory disorders linked to overstocking, inadequate ventilation, mixing of animals and failure of early diagnosis and treatment. Major welfare problems in cattle kept for beef production, as identified by risk assessment, were respiratory diseases linked to overstocking, inadequate ventilation, mixing of animals and failure of early diagnosis and treatment, digestive disorders linked to intensive concentrate feeding, lack of physically effective fibre in the diet, and behavioural disorders linked to inadequate floor space, and co-mingling in the feedlot. Major hazards for white veal calves were considered to be iron-deficiency anaemia, a direct consequence of dietary iron restriction, enteric diseases linked to high intakes of liquid feed and inadequate intake of physically effective fibre, discomfort and behavioural disorders linked to inadequate floors and floor space.
