1. Feed preference of sows (sus scrofa) between ground corn and wheat mill run

2. Objectives Determine preference between ground corn and wheat mill run
Use information to develop palatable feed

3. Materials Used Ground Corn Wheat mill run 6 oz Measuring cup
Hog panels
Stopwatch
10 Yorkshire and Yorkshire cross sows

4. Ground Corn

5. Wheat Mill Run

6. Procedures

7. Test Area

8. 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

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

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

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

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

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

14. Test Area

15. 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
