Article Synopsis
- This study explores the potential of using black soldier fly larvae (BSFL) as a sustainable animal protein source through the manipulation of their amino acid (AA) intake.
- Reducing individual AAs didn't harm BSFL growth, but increasing methionine led to better performance, suggesting it's a key nutrient for their productivity.
- The substrate's microbiome can effectively synthesize AAs to balance deficiencies, potentially enhancing overall nutrition for BSFL, but maximizing growth still requires careful consideration of both substrate and microbial interactions.
Methionine (Met) is a popular nutritional supplement in humans and animals. It is routinely supplemented to pigs as L-Met, DL-Met, or DL-2-hydroxy-4-(methylthio) butanoic acid (DL-HMTBA). We investigated the effect of these Met supplements on jejunal amino acid (AA) transport in male castrated Piétrain × Danbred pigs, also including a non-supplemented group.

Based on a recommendation suggesting that MHA is 65% as effective as DL-Met, many feeding trials have been conducted to challenge this recommendation. A literature search found 25 publications contributing 95 data sets suitable to compute Hedges' g effect sizes used in the meta-analysis.

Furthermore, several different Met sources are available that may have different physiological effects. This study evaluated the mode of action of Met deficiency (no Met-supplementation) and supplementation (0.
