Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of Levucell SB when used in feed for suckling piglets, pigs for fattening and minor porcine species. Levucell SB is the trade name for a feed additive based on viable cells of a strain currently authorised as a zootechnical additive for weaned piglets, sows, chickens for fattening and minor poultry species for fattening. The applicant is now seeking authorisation as a zootechnical additive for use with all pigs. In the context of a previous opinion, the identity of the strain was confirmed, and according to the Qualified Presumption of Safety (QPS) approach to safety assessment, it was presumed safe for the target species, consumers of products from animals fed the additive and the environment. Since no concerns are expected from other components of the additive, Levucell SB is also considered safe for the target species, including all pigs, consumers and the environment. Levucell is not a skin or eye irritant or a skin sensitiser. Inhalation exposure is unlikely. Encapsulation used in the existing coated forms is not expected to introduce hazards for users. In previous opinions, Levucell SB was found to have the potential to be efficacious in sows and weaned piglets at the dose of 1 × 10 colony forming units (CFU)/kg complete feedingstuffs. Since the dose proposed for use with all pigs is the same as that demonstrated to be effective in weaned piglets and sows, and it can be reasonably assumed that the mode of action is the same, the conclusion on efficacy for weaned piglets and sows can be extrapolated to all pigs. Therefore, the FEEDAP Panel concludes that Levucell SB has the potential to be efficacious in all pigs at 1 × 10 CFU/kg feedingstuffs.
应欧盟委员会的要求,动物饲料添加剂及产品或物质专家小组(FEEDAP)被要求就乐菌素SB(Levucell SB)用于哺乳仔猪、育肥猪及小型猪种饲料时的安全性和有效性发表科学意见。乐菌素SB是一种饲料添加剂的商品名,其基于一种菌株的活细胞,该菌株目前已被批准作为断奶仔猪、母猪、育肥鸡及小型育肥家禽品种的动物技术添加剂。申请人现寻求将其批准为用于所有猪的动物技术添加剂。在之前的一份意见中,该菌株的身份已得到确认,根据安全评估的合格假定方法(QPS),假定其对目标物种、食用添加该添加剂饲料的动物的产品消费者及环境是安全的。由于预计该添加剂的其他成分不会引起担忧,因此乐菌素SB也被认为对包括所有猪在内的目标物种、消费者及环境是安全的。乐菌素不会刺激皮肤或眼睛,也不是皮肤致敏剂。吸入暴露的可能性不大。现有的包衣形式中使用包囊预计不会给使用者带来危害。在之前的意见中,发现乐菌素SB在剂量为1×10菌落形成单位(CFU)/千克全价饲料时,对母猪和断奶仔猪有潜在的功效。由于提议用于所有猪的剂量与已证明对断奶仔猪和母猪有效的剂量相同,并且可以合理假定其作用方式相同,因此关于断奶仔猪和母猪功效的结论可以外推至所有猪。因此,FEEDAP小组得出结论,乐菌素SB在饲料中添加量为1×10CFU/千克时,对所有猪都有潜在的功效。
