Results: Amount of Manure Removed From Stalls

Six days of data were collected for manure removed from stalls. Mares and geldings produced different amounts of manure. Mares produced less manure with sawdust bedding than geldings and geldings produced less manure with pelleted bedding than mares. Both mares and geldings produced less manure with pelleted bedding than sawdust bedding.

Table 1 (below) shows that mares produced an average of 55.4 pounds of manure per day when bedded on sawdust and 46.6 pounds of manure per day on pellets. Geldings produced 61 pounds and 40 pounds of manure respectively. On a volume basis, mares produced 1.04 cu.ft. of manure per day on sawdust and 0.78 cu.ft of manure per day on pellets. Geldings produced 1.19 cu.ft and 0.65 cu.ft of manure respectively. Combined, all horses produced an average of 58 pounds or 1.12 cu/ft of manure on sawdust, compared to 43 pounds and 0.72 cu.ft. of manure on pellets.

The weight of manure removed per day from pellet bedded stalls was 15 pounds less and 0.4 cubic feet less than the manure from sawdust bedded stalls. When extrapolated over a year, this results in 2.7 tons or 5.4 cu.yd. less manure that would need to be disposed of by the horse keeper.
