National Farm Animal Care Council Code of Practice：行业守则，不是制定法。NFACC表示，守则的要求在大多数省份并无明文约束力，但可作为动物受困扰的证据。省级法律的援引情况：NL采纳该守则（NLR 36/12；NLR 35/12 s.15规定，守则所禁止的做法即为被禁止的做法），SK规定为适用守则（Reg 1 s.3-4），NB（Reg 2000-4 s.4(2), Sch A）和BC（B.C. Reg. 34/2019，作为普遍接受的做法）将其列为抗辩理由，NS予以接受（Act s.28(b)）。必须评估是否有必要；仅在认定有必要时才进行。

National Farm Animal Care Council Code of Practice: an industry code, not a statute. NFACC says Code requirements are not explicitly binding in most provinces but can be evidence of distress. Referred to in provincial law: adopted in NL (NLR 36/12; NLR 35/12 s.15 makes a practice a code prohibits a prohibited one), prescribed in SK (Reg 1 s.3-4), named as a defence in NB (Reg 2000-4 s.4(2), Sch A) and BC (B.C. Reg. 34/2019, as generally accepted practice), accepted in NS (Act s.28(b)). The need must be evaluated; only when deemed necessary.
