Abstract
Aim: To know the feasibility of hygienic
and environmentally safe method of disposal of
broiler slaughter house waste with coir pith and
caged layer manure.
Materials and Methods:
Compost bins (4 feet x 4 feet x 4 feet) were
established with concrete blocks with air holes to
facilitate aerobic composting. The broiler
slaughter waste and coconut coir pith waste were
collected from the local market, free of cost. The
caged layer manure available from poultry farms
were utilized as manure substrate. Physical
properties and chemical composition of ingredients
were analyzed and a suitable compost recipe was
formulated (USDA-NRCS, 2000). Two control bins
were maintained simultaneously, using caged layer
manure with coir pith waste and water in a ratio
of 0.8:3:1.2 (T2) and another one bin using caged
layer manure alone(T3).
Results: At the end
of composting, moisture content, weight and the
Volume of the compost were reduced significantly
(P<0.01), pH, EC, TDS, total organic carbon and
total nitrogen content were also significantly
(P<0.01) reduced at the finishing of composting.
Calcium, phosphorous and potassium content was
progressively increased during composting period.
The finished compost contains undetectable level
of salmonella. Cowpea and sorghum seeds showed
positive germination percentage when this finished
compost was used. It indicated that all of the
finished compost was free from phytotoxin
substances.
C
onclusion: The results
indicated that, composting of slaughter waste
combined with coir pith waste may be a hygienic
and environmentally safe method of disposal of
broiler slaughter house waste.
