Abstract

The purpose of this research project was to investigate the effect that the number of hours kept stalled per day had on the number of strongyle type eggs and larvae in equine manure samples. The independent variable was the number of hours horses were kept stalled per day. Horses were either stalled 0 hours per day (control group) or 8 hours per day. The dependent variable was the number of strongyle type eggs and larvae present in manure samples from these horses. It was hypothesized that the manure of horses stalled 8 hours per day would contain more strongyle type eggs and larvae than that of horses stalled 0 hours per day. The null hypothesis stated that there would be no difference between the two groups. The manure samples were collected, mixed with a sodium nitrate solution, then syringed into two chamber McMaster slides. The eggs and larvae were counted under a light microscope and the eggs per gram was calculated. A two tailed T-test (alpha=0.05) was completed to determine if there were statistically significant differences between the tested groups. The results suggested that these groups were not quite different enough for statistical significance to be considered.
