National Farm Animal Care Council Code of Practice：業界の規範であり、法律ではない。NFACCによれば、規範の要件はほとんどの州で明示的な拘束力はないが、苦痛の証拠になり得る。州法での扱い：NLは採用（NLR 36/12。NLR 35/12 s.15は、規範が禁じる行為を禁止行為とする）、SKは指定（Reg 1 s.3-4）、NB（Reg 2000-4 s.4(2), Sch A）とBC（B.C. Reg. 34/2019、一般に認められた慣行として）は抗弁として明記、NSは容認（Act s.28(b)）している。必要性を評価しなければならない。必要と判断された場合に限る。

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.
