Abstract: The paper aims to develop grape pomace as a new type of feed resources scientifically, we measured the hygienic index, nutrient content and amino acid composition of grape pomace by national standard methods, and analyzed the value of essential amino acids by international general methods. The results showed that: the grape pomace hygienic index, including Pb, As, Hg, Cd, F, aflatoxin, bacteria, total number of molds met the national standard of feed hygiene; the conventional nutrient content in grape pomace contained crude protein of 12.0%, crude fat of 8.4%, crude fiber of 29.5%, crude ash of 3.2%, Ca of 0.82%, total phosphorus of 0.08%; the total amount of amino acids was 10.78%, with the proportion of essential amino acids 34.88%, and the delicious amino acid accounted for 43.43% of the total amino acid; the chemical score (CS), amino acid score (AAS), essential amino acid index (EAAI), biological value (BV), nutrition index (NI) and Score of Ration Coefficient of Amino acid (SRCAA) of grape pomace protein were 43.3, 47.7, 65.8, 60, 7.9, and 76.3, respectively. Grape pomace, with other well-balanced essential amino acids except for the insufficient sulfur-containing amino acids of first limiting amino acid, it is a new feed resource to be developed.
