Drs. Ventura and Zhitnitskiy, faculty members in the College of Food, Agricultural, and Natural Resources and the College of Veterinary Medicine at the University of Minnesota recently published a new article regarding the influence of point-source enrichment on the behavior of gestating sows housed in groups. The article is available in open-access on the Frontiers in Animal Science website.
- Most common observed behaviors were sows being inactive (73%), followed by sham-chewing (16%). Enrichment use made up only 1% of observations.
- Number of observed interactions with enrichment decreased sharply on the second day.
- Low-parity sows, moderately-lame sows, and sham-chewing sows interacted more with the enrichment.
- No increase in adverse effects (agonistic behaviors, sham-chewing) was observed.
