Well-being of the animal

The health or well-being of the animals will not be in any way endangered by the manner of keeping or confinement. This includes enough food, water, attend to special needs such as hoof care for goats and sheep, and skilled care for sick animals.

Condition of animal structures

The facility is in good repair, adequately ventilated, capable of being maintained in a clean and sanitary condition, free of vermin, obnoxious smells, and accumulated waste.

Best practices for miniature pigs

  • Pigs are social animals. It is recommended that owners keep other pets and provide frequent human interaction.
  • Recommendation on the size and configuration of the pen is 10 square feet per pig.
  • An outside run is recommended so that there is an opportunity for the pig to use its natural instincts to forage for roots and fungi.
  • Recommendations for ground cover: Blankets are recommended for the inside of a pen and straw or hay are recommended for outside.
  • Because pigs root, surface material such as rock or mulch won’t stay in place over the long term, although mulch in the outdoor space provides enrichment and may reduce mud

Guidelines on slaughtering

  • Meat is for personal consumption and may not be sold, unless raised as an agricultural use (on land zoned for agricultural uses).
  • Slaughtering should be done out of the public review, view from neighboring properties, and the view of other animals.

Vector control

  • Feed and any supplement used to support animal health must be stored in a sealed container that is not penetrable by rodents or other animals.
