Abstract :
To identify a suitable substrate to enhance
sustainable access to affordable quality feed protein in
Uganda, growth performance and nutritional
composition of housefly larvae grown on three common
substrates; cow dung (CD) chicken manure (CM) and
brewery waste (BW) for 5 days was determined.
Eighteen bags were randomly filled with one kilogram
(1000g) of each of the three substrate in six replicates
were allowed to attract adult housefly that deposited
eggs whose larvae were harvested on the 3
rd
, 4
th, and 5th
day. The weight of larvae was 43.72 for CM, 39.65 for
BW and 33.91 for CD. The crude protein ranged from
45.38-44.21 for CD, 48.60-53.0 for CM and 46.24-50, 32
for BW and significantly differed among substrates
(p<0.05) with the highest recorded in chicken manure
(CM). On the other hand, the crude protein was
significantly high in larvae nourished with Chicken
manure (CM) and lowest in cow dung (CD) crude fat did
not significantly differ. Results from the study indicated
that culturing housefly larvae on chicken manure for 3
days post egg laying offers higher biomass and
nutritional quality protein than using cow dung and
brewery waste.
