This document discusses the benefits of composted bedding re-use in the equine industry. It outlines the operational, financial, and health benefits, including reduced parasites, flies, dust, and odor, as well as lower labor needs. Financially, composted bedding re-use can reduce shavings costs by 40%. Health benefits include improved foot, leg, skin, and respiratory health in horses. The document also examines different composting methods and the mechanisms by which composting reduces pathogens. Clinical observations and studies show relief for horses with hives and respiratory issues when using composted bedding.

15. The Probiotic Effect
“The compost has been through a very hot
phase to kill all pathogens and parasites. It now
has a thriving microbial population to compete
aggressively with the fungal and bacterial
pathogens responsible for infections and
irritations on skin and hooves.”

Notes de l'éditeur
Introduce myself and Michael. Barn owner for 30+ years, managed about 50 horses. Issue arose with manure disposal. Lucky to be in MBA program – met Michael – existing food waste business was able to use existing technology to stable waste. Michael insisted that I try the compost as bedding and I witnessed some interesting things. Not only was the stall drier but my retired show jumper who had suffered from chronic scratches begain to heal. With that I began to research in earnest what information existed on bedding re-use.
More efficient operation adds to the financial well being. Better health adds to the financial well being. Those benefits together with the possibility of a closed loop waste stream and a value added component to the operation of the farm or stable is an enormous opportunity.
Temp log graph form IOS
Temperatures at which the material composts on a uniform basis kills weed seed and parasite larvae. The make up of the composted material reduces dust. The in- vessel composting system eliminates odor and leachate issues.
The material loaded into a vessel decreases in volume within a relatively short period time
Remarkable thing about compost bedding is the fact that it has the benefits of a higher moisture content that shavings therefore less dust and has a higher capability to absorb that shavings. More of the urine will be soaked up by the compost material than with new shavings. It acts similarly to pellets.
Look closely at the bottom right corner. The pellets absorb the moisture well but leaves a very soggy area that the horse will be standing on with the hoof and skin in direct contact with the moisture. ***MBB does it make sense that moist skin/hoof is more susceptible to being irritated.
Benefits of this: highly capable moisture retention with compost on base of stall and a barrier to that moisture provided by the less moisture retentive green shavings.
