Revamping porcine enrichment (2019)

Heyworth, C.

Abstract

Pigs may exhibit stereotypic behaviors due to lack of proper mental stimulation. Stereotypic behaviors include self-inflicted wounds, biting at the pen, polydipsia, cage destruction, and loud vocalizations. These behaviors may be alleviated with proper daily enriching stimulation. Pigs enjoy a challenge and the degree of difficulty when foraging is fun for them. This article describes a variety of creative edible enrichment ideas for laboratory pigs.
