Use of on-farm emergency slaughter for dairy cows in British Columbia

On-farm emergency slaughter (OFES), whereby inspection, stunning, and bleeding occur on the farm before the carcass is transported to a slaughterhouse, is permitted in some jurisdictions as a means to avoid inhumane transportation while salvaging meat from injured animals. However, OFES is controversial and its use for dairy cows has been little studied. Inspection documents for 812 dairy cows were examined to identify how OFES was used for dairy cows in British Columbia, Canada, over 16.5 mo. Producers used OFES for dairy cows aged 1 to 13 yr (median of 4 yr). Leg, hip, nerve, spinal, foot, and hind-end injuries or conditions (in that order) were the most common reasons for OFES, and some cases may have been a consequence of calving. Foot conditions were disproportionately common among cows 5 yr and older, and hind-end conditions were disproportionately common among cows 6 yr and older. Producers used OFES promptly after traumatic injury (within 1 d) for some cows, but OFES was delayed for others, sometimes until cows had been nonambulatory for 2 to 6 d. In some cases, OFES was used for nontraumatic chronic conditions, such as lameness and hind-end weakness, rather than traumatic injuries such as fractures and dislocated hips. Use of OFES appears to conform to the purpose of the program when used promptly after traumatic injuries, but clear guidelines are needed to avoid inappropriate use and delays that may prolong animal suffering.

在不列颠哥伦比亚省使用农场紧急屠宰牛群

在某些辖区允许在农场紧急屠宰(OFES),以便在将s体运到屠宰场之前在农场进行检查,击晕和渗血,以此作为从受伤动物身上抢救肉时避免不人道运输的一种手段。但是,OFEs引起争议,其在奶牛中的用途还很少进行研究。检查了812头奶牛的检查文件,以确定在加拿大不列颠哥伦比亚省超过16.5个月的情况下OFES是如何用于奶牛的。生产者将OFES用于1至13岁(平均4岁)的奶牛。腿,髋,神经,脊柱,足和后肢受伤或状况(按顺序)是发生OFES的最常见原因,某些情况可能是产犊的结果。在5岁及以上的母牛中,足部疾病比例不成比例,在6岁及以上的母牛中,后部情况不成比例地普遍存在。生产者对一些奶牛在受伤后(1 d内)立即使用了OFES,但对其他奶牛则推迟了OFES,有时要等到奶牛2到6 d不再活动时才使用。在某些情况下,OFEs用于非创伤性​​慢性病,例如la行和后肢无力,而不是诸如骨折和髋关节脱位的外伤性损伤。在外伤后立即使用OFES似乎符合该计划的目的,但是需要明确的指导原则以避免不当使用和延误可能会延长动物的痛苦。在某些情况下,OFEs用于非创伤性​​慢性病,例如la行和后肢无力,而不是诸如骨折和髋关节脱位的外伤性损伤。在外伤后立即使用OFES似乎符合该计划的目的,但是需要明确的指导原则以避免不当使用和延误可能会延长动物的痛苦。在某些情况下,OFEs用于非创伤性​​慢性病,例如la行和后肢无力,而不是诸如骨折和髋关节脱位的外伤性损伤。在外伤后立即使用OFES似乎符合该计划的目的,但是需要明确的指导原则以避免不当使用和延误可能会延长动物的痛苦。
