Procedures

Test Area

Wilcoxian sign-rank test Statistical analysis Wilcoxian sign-rank test Average time spent eating Initial choice Side preference Spearman rank test Correlation of initial choice and overall choice

Average choice of feedstuffs based on time X=3, P>0.05

Initial choice of feedstuffs Sign Test, X=2, P>0.05

Correlation between initial choice and average time spent eating Correlation of 76.67% Correlation of 93.13%

Number of times sows chose feeds based on proximity to side of release X=3, P>0.05

Confounding factors Motivation Feed presentation Hierarchy Health Curiosity Boars On ground vs. in feeder Pellets vs. ground material

Test Area

Conclusions Sows have no preference for either ground corn or wheat mill run There was no correlation between initial choice and duration of eating that choice Side of release did not affect sows’ choices
