“…In China, various insect species, including BSF, HF, mealworm, or superworm, have been studied in different feeding phases, from weaned pigs to finishing pigs [20][21][22][23]. However, the study with growing pigs was for ileal digestibility determination [23], and the study with finishing pigs was for microbiota and gene expression analyses [21].…”

Among edible insects, black soldier fly (Hermetia illucens), yellow mealworm (Tenebrio molitor), and common housefly (Musca domestica) have been considered as an alternative protein source for pigs.Because they are easy to breed and grow in the organic wastes, and they have well-balanced nutritional value as a protein source for pigs. The black soldier fly larvae and mealworm could replace the fish meal in the diets for weaned pigs without adverse effects on growth performance and nutrient digestibility. Black soldier fly could also be included in the finishing pig's diet without any negative effects on the growth performance and pork quality of the market pigs. Insect products showed a greater standardized ileal digestibility value of amino acids than conventional animal proteins in growing pigs. Due to the limited amount of insect products used for pig feeding study, most previous pig studies have been conducted in the weaned pigs. Thus, further study is needed about the optimal inclusion level of insect products in every phase diet from weaned pigs to sows. The use of insect products in swine diets has some challenges in terms of cost, supply, and safety. Lastly, intrinsic differences among insect species, processing method, and feeding phase should be taken into consideration for the use of insect products in the swine diets.

This review is focusing on effects of inclusion of insect products in pig diets on digestibility, performance, product quality, and health parameters. In 2019 pig feed accounts for 23% of the global feed production. Soybean meal is the most common protein source in pig diets. A shift towards more sustainable feed ingredients can improve the sustainability of entire pig production. Novel protein sources currently evaluated in diets for piglets and growing pigs are insect-based ingredients. Insects are able to convert organic biomass into high-quality protein. Currently the use of insects as protein source in pig diets is not allowed due to transmissible spongiform encephalopathies regulation but it is expected that this will be allowed in the near future. Research efforts on effects of inclusion of insect products on nutrient digestibility, growth performance, product quality and pig health are therefore increasing. Nutrient digestibility of evaluated insect proteins was comparable with traditional protein sources. Nutrient digestibility of insect-based diets as well as effects on growth performance in pigs fed insect-based diets differed between studies. The differences in responses are mainly due to changes in diet ingredients and nutrient composition when insect products are included. Health related parameters were not affected by dietary inclusion of insect products. In general it can be stated that differences in results between studies may be due to different insect species and life stages being used, differences in nutritional value of the insect products, in dietary inclusion levels, in processing techniques applied, effects on palatability of the diet, (weaning) age of the animals involved and research methods applied. Overall, insect products seem to be a good alternative to partly replace traditional protein-rich ingredients in pig diets without adversely affecting growth performance, product quality and health, but more standardised research is required to reduce differences between studies.

“…Moreover, AID of alanine and proline tended to increase with increased inclusion of BSFL. The SID values for BSFL published by Tan et al [53] were close to the one used in the diet formulation, but Tan et al [53] also reported a higher AID coe cient for alanine in BSFL than soybean meal. Proline is high in endogenous losses, attributed to low reabsorption of mucin [54], but no information about BSFL affecting endogenous losses was found in the literature.…”

“…AID of lysine tended to decrease with increased inclusion of BSFL. Tan et al [53] reported a SID coe cient of 0.776 for lysine in BSFL. Overestimation of the SID coe cient in the diet formulation of lysine might be the cause of the tendency of reduced AID of lysine with increased BSFL.…”

Background: Weaning is associated with growth decline and morphological changes in the gastrointestinal tract of the pig. Insects, such as the Black soldier fly larvae (BSFL), are suggested as a sustainable novel protein source in diets for pigs. They contain chitin, medium chained fatty acids, and anti-microbial peptides, which could improve the gastrointestinal function and health in the post-weaning pig. The objective of this study was therefore to investigate the effect of increasing inclusion of full-fat BSFL in diets for post-weaning pigs on growth performance parameters, digestibility, gut morphology, and the microbial community in the colon. Eighty crossbred weanling pigs were weaned at approximately 32 days of age, with an average weaning weight of 10.6 ± 0.8 kg. For four weeks, the pigs were fed one of four dietary treatments: a control diet or one of three diets containing an increasing amount of full-fat BSFL meal: 4.76% (BSFL5), 9.52% (BSFL10), and 19.06% (BSFL20). Results: Increased level of full-fat BSFL in the diet did not affect growth performance or fecal consistency. A reduction in apparent total tract digestibility (ATTD) of crude protein (P = 0.035) was found for increased inclusion of BSFL, whereas the ATTD of crude fat increased (P<0.001). Jejunal, ileal, or colonic morphometry was not affected by the BSFL inclusion. Some changes in the colon microbiota were observed, but no differences in the short-chain fatty acid concentrations were detected between the dietary treatments. At the phylum level, dietary treatment affected the relative abundance of Bacteroidota, Firmicutes, Campilobacteria, and Thermoplasmatota, but there was no clear pattern relationship with the BSFL inclusion level. At the genus level, the inclusion of BSFL in the diet reduced the relative abundance of Lactobacillus (P = 0.015) compared to the control. Conclusions: Collectively, the results indicate that up to 19.06% of full-fat BSFL meal could be included in a balanced diet for PW pigs without affecting growth performance, gut function, or health.
