| dc.description.abstract | JOSE JONERY SILANGIT. Evaluation of the Physical Properties of Maggot
Meal (Hermetia illucens) Cultivated on Various Types of Livestock Manure.
(Supervised by YUNILAS).
The use of maggot meal from Hermetia illucens larvae as an alternative
livestock feed offers a promising solution to reduce dependence on imported feed
ingredients such as fish meal and soybean meal. Maggots are rich in protein and
fat and can grow on various organic substrates, including livestock waste. This
study aimed to evaluate the physical properties of maggot meal cultivated on
different types of livestock manure. The experiment was arranged using a
Completely Randomized Design (CRD) with four treatments and three replications:
beef cattle manure (P1), layer chicken manure (P2), meat sheep manure (P3), and
dairy goat manure (P4). Observed parameters included bulk density, specific
surface area, angle of repose, tapped density, and compressibility. The results
showed that bulk density ranged from 1.26 to 1.54 g/cm³, specific surface area from
29.34 to 37.57 mm²/g, angle of repose from 35.27° to 43.53°, tapped density from
0.42 to 0.53 g/cm³, and compressibility from 0.50 to 0.75 g/cm³. The highest values
for each parameter varied depending on the type of manure. The maggot media had
no significant effect (P>0.05) on bulk density, specific surface area, angle of
repose,and pile density, but had a highly significant effect (P<0.01) on compacted
pile density. | en_US |
