Evaluation of Black Soldier Fly Meal as a Dietary Animal Protein Source Replacing Fish Meal in Korean Catfish Silurus asotus

AbstractInsects have been proposed as a high-quality, efficient and sustainable dietary protein source. The present study evaluated the protein quality of a selection of insect species. Insect substrates were housefly pupae, adult house cricket, yellow mealworm larvae, lesser mealworm larvae, Morio worm larvae, black soldier fly larvae and pupae, six spot roach, death's head cockroach and Argentinean cockroach. Reference substrates were poultry meat meal, fish meal and soyabean meal. Substrates were analysed for DM, N, crude fat, ash and amino acid (AA) contents and for in vitro digestibility of organic matter (OM) and N. The nutrient composition, AA scores as well as in vitro OM and N digestibility varied considerably between insect substrates. For the AA score, the first limiting AA for most substrates was the combined requirement for Met and Cys. The pupae of the housefly and black soldier fly were high in protein and had high AA scores but were less digestible than other insect substrates. The protein content and AA score of house crickets were high and similar to that of fish meal; however, in vitro N digestibility was higher. The cockroaches were relatively high in protein but the indispensable AA contents, AA scores and the in vitro digestibility values were relatively low. In addition to the indices of protein quality, other aspects such as efficiency of conversion of organic side streams, feasibility of mass-production, product safety and pet owner perception are important for future dog and cat food application of insects as alternative protein source.

Abstract Heat processing may enhance nutrient digestibility of diets based on pulse grains. The objective of this study was to determine nutrient and energy digestibility of extruded lentil-based diets containing either supplemental plant or animal protein source in growing pigs. Two diets were formulated to provide 2.4 Mcal NE/kg and 4.35 g standardized ileal digestible Lys/Mcal NE: 1) soybean meal diet (SBM), containing 50% lentil, 31% wheat, and 12.8% soybean meal; and 2) fish meal diet (FM), containing 40% lentil, 45% wheat, and 10% fish meal. Following mixing, each diet was divided into 2 parts: one part remained mash while the other part was extruded using a single-screw extruder (105°C, 400 rpm, 5 kg water/h). The 2 extruded and 2 non-extruded diets were tested in a 2 × 2 factorial arrangement. Eight ileal-cannulated barrows (32.3 kg) were fed the 4 diets at 2.8 times maintenance DE (110 kcal per kg of BW0.75) for four 9-d periods in a double 4 × 4 Latin square. The FM diets had greater (P < 0.05) AID of DM, GE, and most AA, and ATTD of CP, but lower apparent hindgut fermentation of DM and GE than the SBM diets. The AID of CP and AA were 3.2 and 4.7%-units greater (P < 0.05), respectively, and the ATTD of GE and DE values were 2.1 and 3.1%-units greater (P < 0.05), respectively, for the extruded diets than the non-extruded diets. Interactions between protein source and extrusion were not observed. In conclusion, FM diets had greater ileal digestibility of DM, energy, and AA than SBM diets. Extrusion increased the AID of CP and most AA, and DE value of both plant- and animal-protein diets based on lentil grain, indicating that extrusion can increase the energy and protein value of pulse-grain based diets fed to growing pigs.

Amino Acid Requirements

Increasing demand of protein source for animal feed, particularly fish meal and soybean meal has led to a problem in the future. It is a need to look for an alternative protein source, in order to meet amino acid requirements maintaining livestock production level. Insects possesing high quality, efficient dan rich protein content at all life stages such as Black Soldier Fly (BSF, Hermetia illucens) could be used as one of the alternatives. The flies grow and reproduce easily, have high feed efficiency and can be reared on bio-waste streams. These are neither pests nor vectors of diseases. Insect meal generally possesses levels of chemical contaminants which are below recommended maximum concentrations. The larvae have antibacterial (Escherichia coli O15:H7, Salmonella enterica serovar Enteritidis) and antiviral (enterovirus and adenovirus ) properties. Larvae of BSF could be scaled up easily and possess 40-50% protein content, including some essential amino acids that can be used to replace both fish meal and soybean meal in feed.

Enzyme Supplementation

The effects of enzyme supplementation of shrimp waste meal (SHM) based diets on the performance and nutrient utilization of starter and finisher broilers were studied. One hundred and twenty day old broilers (Anak sirain) were randomly divided into four groups of 30 birds each. Each group was further divided into three replicates of 10 birds each. The birds were assigned the four dietary treatment in 2 X 2 factorial design, Diets 1 and 3 had fish meal as the sole animal protein source, diets 2 and 4 had shrimp waste as the animal protein source. Diets 1 and 2 were without enzymes while diels 3 and 4 were supplemented with enzyme. Records of performance, nutrient utilization, blood parameters and carcass characteristics were taken. The values of average final weight, daily weight gain, feed conversion ratio and protein efficiency ratio at starter and finisher phases were not significantly (P>0.05) influenced by the dietary treatment. The daily feed intake of the starter broilers fed diet 3 (fish meal based diets with enzyme) was significantly (P<0.05) higher than those of other treatment. Birds fed fish meal diet without enzyme had the highest serum uric acid and serum cholesterol at the starter phase. Finisher broiler fed fish meal based diet without enzyme had a significantly (P<0.05) higher serum creatinine value. Carcass characteristics measured were not significantly influenced by the dietary treatments. It was concluded that SWM can be employed as an animal protein source in broiler diets. The exogenous enzyme (Roxazyme G) used did not effect any appreciable improvement on the utilization of SWM based diets.
