Annually, 1.3 billion of tons food waste is produced worldwide. Vegetal waste (VW) makes 2/3 of this amount. Due to current disposal solutions, this waste contributes significantly to environmental pollution. Recent years have seen several novel waste management strategies, including sustainable utilization of vegetal wastes for the development of animal feed. VW represents an alternative to the current feed material due to its rich bioactive compounds content. This study included an evaluation of apple pomace and oat bran as animal feed supplements. Following analyses were undertaken: proximate analyses, metabolizable energy and protein, mineral, vitamin, fatty acid and amino acid content. Regarding the influence of extraction parameters: time, volume of solvent and temperature on amino acid content, only the mass was a statistically significant parameter. Apple pomace showed small amount of crude protein but a high content of crude fibre, comparing to oat bran which had high crude protein content but low amount of crude fibre. Oat bran showed significant amount of iron and zinc. 37 amino acids were detected in both samples. Apple pomace showed low amounts of amino acids compared to oat bran, except for cysteine. High amount of numerous amino acids was detected in oat bran.
