Abstract
The objective of this study was to identify the bioactive compounds present in avocado agro-industrial residues that could serve as an alternative ingredient in animal feed in arid and semi-arid regions of Mexico. Residue samples were collected from a guacamole processing plant in the Bajío region of Mexico for proximal chemical analysis and biocompound analysis using gas chromatography coupled with mass spectrometry. Residues had a chemical composition higher than that of some forages, with 93.35 % dry matter, 5.74 % crude protein, 17.5 % ether extract, 32.14 % neutral detergent fiber, 26.58 % acid detergent fiber, and 5.59 % ash content. Additionally, 129 different compounds were identified, including vitamin E, sitosterol, hexadecanoic acid, octadecanoic acid, and pentadecanoic acid. Therefore, the results indicate that avocado agro-industrial residue can be considered as an alternative feed source, because the bioactive compounds it contains may be beneficial when included in the diet of livestock in the arid and semi-arid regions of Mexico.
