Mealworm feeding on Giant River Prawn (Macrobrachium rosenbergii)…
Mealworm feeding on Giant River Prawn (
Macrobrachium rosenbergii
)
Why? Justification?
Growing market
act pressure on fish meal (FM)
Mealworm meal (MM) act as alternative meal
etc: catfish, tilapia, trout, frog farming
Same result yield
-MM utilize small land and small maintenance
Pro
low ash + moisture content
slightly high crude lipid
X significant difference v FM
Crude Protein
potential replacement dietary protein
methionine (supplement)
High feed digestibility of protein
-all essential amino acid
High Vitamin & Minreal
-B2 , B12 Zinc , Magnesium
Moisture content
-oven drying (105 °C)
Crude Protein
-Kjeldahl digestion
Crude lipid
-Soxhlet extration
Ash content
-furnace muffler (550 °C)
Gross Energy
-NRC (1993)
E amino acid
-Liquid Chromatography
Research Design
N Prawns
Susceptible to Multiple Treatment (T1, T2 T3...)
Grow Parameter
Specific growth rate
Daily feed intake
Weight gain
Protein retention effciency
survival rate
Feed conversion rate
Proximate analysis
Crude
Protein, Lipid, Fibre
Content
Moisture, Gross energy, E amino acid
Dry matter
Antibiotic residue on shrimp & prawn farming
USA- Malaysia shrimp exporter (red list)
etc: Penang exporter
Antibiotic resistance
MAR index
Contamination encouter with high risk antiobiotic residue (>0.2)
Furazolidine (best efficiency)
-Lincomycin & Oleandomycin (tolerant)
M. rosenbergii
larval
Vibrio
spp
Aeromonas
spp.
Pseudomonas
spp.
Sediment tank
-heavy metal failed (inhibition )
-antibiotic residues
Antibiotics over-dosage
-chloramphenicol
-nitrofuran
-carcinogenic
-bone marrow degrade
Probiotic enriched Mealworm
Enriched with multiple microbes
Synergistic effect of Growth performance
Increased IG level
-fermentation (facilitate digestion)
-high digestible crude protein
Effect on excrete content ? pH?
