OBSERVATIONS OF DIFFERENTIAL DECOMPOSITION ON SUN EXPOSED V SHADED PIG CARRION IN COASTAL WASHINGTON-STATE

The decomposition of two pig carcasses in close proximity to each other, one exposed and the other shaded, in a continuous woodland were observed and different rates of decay were recorded. The exposed pig decomposed much faster than the shaded pig, reaching a stable minimal weight two weeks before the shaded carcass. Bloat size, body weight, occurrence of blow fly larvae, and ambient air temperatures are compared. Maggot development appeared to be a major factor in the overall rate of decomposition and was affected primarily by different temperature patterns at the two sites.
