Animal mortality is a fact of life, and in livestock production the challenge is dealing with the number of animals over time and their size.
It is becoming more difficult to find outlets for spent animals, and cost must be considered. Mortality composting has gained in popularity over the years, but with that practice comes concerns related to nutrient management. T
here were several papers on animal mortality management presented at the Waste to Worth Conference held in April 2016. Craig Williams, Extension educator in Tioga County, gave two presentations on mortality composting.
He worked with a swine producer wanting to switch from burial to composting. This operation had a three percent mortality rate, or approximately 250 deaths per year in the finishing operation. The producer built a compost barn with a three-foot center dividing wall.
In the first year, approximately 56 cubic yards of wood chips/bark mulch was used. In the second year, this was replaced with 40 cubic yards of sawdust. The compost temperature is reaching 130 degrees, and so far there have been minimal issues in mixing and turning the compost. | For the full story, CLICK HERE.
