Chitinase improves the available energy, amino acids digestibility of black soldier fly and fecal microbiota of growing pigs.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe main objective of this study was to determine the energy value and digestibility of amino acids in growing pigs fed black soldier fly (BSF) with chitinase supplementation and its effect on fecal microbiota.
methodsIn Exp. 1, eighteen barrows with initial body weight (BW) of 31.6±1.2 kg were randomly assigned to 3 treatments to determine the digestible energy (DE), metabolizable energy (ME), and nutrient digestibility, including the corn-soybean meal basal group, the BSF (14.6%) with 1,500 mg/kg or without chitinase groups. Fresh feces were collected on day 10 of feeding for analysis of microbial diversity. In Exp. 2, six barrows (36.7±4.2 kg BW) with ileal T-cannulas were arranged in a 6×3 Youden square design, pigs were allotted to 3 dietary treatments to determine the digestibility of the amino acids, including the nitrogen-free group, the BSF with or without chitinase groups.
resultsSupplemental chitinase improved (p<0.05) the apparent total tract digestibility (ATTD) of crude protein and dry matter in the BSF diet, improved (p<0.05) the ATTD of crude protein, ether extract and acid detergent fiber in the BSF, and increased the BSF's DE and ME by 2.34 MJ/kg and 1.37 MJ/kg, respectively. Chitinase supplementation improved (p<0.05) the composition of fecal microbiota of growing pigs, promoted (p<0.05) the colonisation of Bacilli, Lactobacillaceae, and Lactobacillales, and inhibited (p<0.05) the proliferation of pathogenic bacteria Sarcina. Adding chitinase enhanced the apparent ileal digestibility and standardized ileal digestibility of most amino acids in BSF, such as methionine, leucine, and glutamate (p<0.05).
conclusionAdding chitinase can increase the effective energy value and amino acid ileal digestibility of BSF, regulate the composition of fecal microbiota and improve the intestinal health of growing pigs.
