In Canada, due to cattle population demographics, receiver calves are obliged to undergo significant exposure to transport and handling, co-mingling, auction and some time off feed and water (Schaefer et al., 2003, CSAS Proceedings). Collectively, these novel events result in a significant incidence of Bovine Respiratory Disease (BRD) which has a considerable economic impact on the cattle industry both with respect to health and treatment costs and animal performance (Basarab et al., 1997. Can. J. Anim. Sci. 77:554; Wittum et al., 1996. J. Amer. Vet. Med. Assoc. 209:814). As discussed by Jericho and Kozub (2004. Can. J. Vet. Res. 68:127) the presence of BRD in intensively raised cattle has caused a dependence on antibiotic treatments which in turn has lead to a concern for the promotion of antibiotic resistant microbes. In fact, the ability to treat BRD in cattle is reported to be becoming more difficult due to the emergence of resistance microbes such as pneumonia in multiple sourced co-mingled cattle (Shahriar et al., 2002. Can. Vet. J. 43:863).

在加拿大，由于牛的种群统计数据，接收小牛必须经历大量的运输和处理、混合、拍卖和一段时间的饲料和水（Schaefer等人，2003年，CSAS Proceedings）。总的来说，这些新事件导致牛呼吸道疾病（BRD）的显著发病率，在健康和治疗费用以及动物生产性能方面对养牛业产生相当大的经济影响（Basarab等人，1997年）。可以。j .似的。Sci 77:554;Wittum et al., 1996。j·阿。兽医。医学杂志，2009:814)。正如Jericho和Kozub（2004）所讨论的那样。可以。j .兽医。Res. 68:127)在集约化饲养的牛中BRD的存在导致了对抗生素治疗的依赖，这反过来又导致了对促进抗生素耐药微生物的关注。事实上，据报道，由于在多源混合牛中出现肺炎等耐药微生物，治疗牛BRD的能力变得越来越困难（Shahriar et al., 2002）。可以。兽医。j . 43:863)。
