Dairy Manure Handling Systems Decrease Fly Production

Dairy Manure Handling Systems Decrease Fly Production

Dairy Manure Handling Systems Decrease Fly Production

Stable flies and houseflies are economically-hindering pests on dairies, inflicting damage in different ways. The stable fly sucks blood from dairy cows, which can causes milk production losses due to altered cow behavior during periods of high fly activity. Houseflies become a nuisance to the dairy producer when excessive fly numbers result in complaints from neighbors. As dairy farms grow larger, producers struggle with handling large volumes of manure that is generated by dairy animals and which also can produce excess fly populations. Various manure handling systems exists for dairy producers to handle the manure waste generated on the dairy. Gerald Higginbotham has been evaluating fly production from manure handling systems on local dairies. These systems consist of different types of settling basins where the dairy waste accumulates with the liquid portion draining off with the remaining solid portion used as fertilizer for cropland. Of the systems evaluated, composted dairy manure produced fewer total flies. Dairy producers who utilize this type of manure handling system may generate less fly production from their dairy facility
