The amount of waste produced by horse establishments and lack of space for its disposal are serious problems faced by everyone who deal with horses. Another problem is related to the enviroment, specially soil and underwater contamination, flies multiplication and pasture reinfection.
The aim of this work was to verify composting efficacy on equine gastrointestinal parasites elimination.
Six horses were kept in individual stables with wood straw bedding, during 15 days. The saturated bed with feces and urine was collected daily and after this period six piles (1,80x0,90x2,10mts) was built. An aerobic fermentation system, in a slow decomposition process was held during 90 days. Humidity was maintained between 40 to 60% and temperature was monitored daily. 30 grams of compost were collected on day 1, day 5 (begining of the termophilic phase, with higher temperatures), day 30 (mesophilic phase) and day 90 (end of composting process). All sample were transported to Parasitology Lab for analysis. Mean temperature of piles reached 55oC on day 7. On day 30, mean temperature of 40oC was a characteristic of mesophilic phase. After that, temperature remained stable (30 to 35oC), until day 90. More than 50 eggs per gram was found at the beginng of the process (days 1 to 3), and after that, no egg was found. Strongylus spp larvae revealed a peak count on the fifth day (1 larva/gram) showing significant reduction until the end of process.
Helmints eggs disapeared in the first few days due to eclosion, with ideal conditions, for larvae development. Larvae were detected in the begining of composting process and were also eliminated.
Composting of equine bedding revealed to be an easy and efficient method to eliminate eggs and larvae of equine gastrointestinal worms. It is very important for horse welfare and also important for enviromental protection and equine industry sustainability.
