If, as a slaughterhouse, you slaughter at least 50 livestock units per week or provide workers who feed, stun or bleed animals for slaughter, you must appoint a responsible person to the competent authority who will ensure compliance with the requirements of the Animal Welfare Act and the ordinances issued on the basis of this Act.
This provision applies, for example, to subcontractors who have been commissioned by the slaughterhouse operator to carry out the aforementioned activities. Despite the appointment of a responsible person authorized to issue instructions by a subcontractor, the slaughterhouse operator must also appoint an animal welfare officer.

You should note the following conversion of livestock units:

• Adult cattle and solipeds: 1 LU
• Other cattle: 0.5 LU
• Pigs weighing over 100 kg: 0.2 LU
• Other pigs: 0.15 LU
• Sheep and goats: 0.1 LU
• Sheep/goat lambs and piglets under 15 kg: 0.05 LU
