## Results: Costs Comparison of Bedding Material

When comparing the cost of the two bedding materials, several items were considered. Table 3 lists the cost of getting the bedding material into the barn storage area.

The initial cost of the pelleted bedding for this project was 15 times more expensive than the sawdust bedding on a weight basis, but only 6 times more expensive on a volume basis.

Table 4 shows that the amount of sawdust used for bedding on a weight basis was almost 1.5 times as much as the pellets, while on a volume basis, 4 times as much sawdust was used. The difference in amount of bedding used for the year was calculated at 20 cubic yards.

The amount of labor to clean the stalls shown in Table 5 was only slightly different, with the sawdust taking about half a minute more per day to clean. A greater discrepancy in time was observed between mares and geldings. It was observed that at the end of the week, the pelleted bedded stalls were dustier than the sawdust bedded stalls.

When considering the initial cost, the amount of bedding used and the amount of manure removed from stalls, the break-even cost of manure disposal would be \$350 per ton or \$110 per cubic yard.
