Abstract:To study the difference of nutritional value of Zhedong geese and Landes geese, the contents of nutritional component in chest and leg muscle of Zhedong geese and Landes geese were determined. The results showed that crude fat content of Zhedong geese was higher than that of Landes geese. However, crude protein and crude ash contents were almost same in Zhedong geese and Landes geese. Both Zhedong geese andLandes geese had a wide variety of amino acids, and their essential amino acids (EAA) compositions and structures fit in FAO/WHO recommended pattern for amino acids. The first limited amino acid in Zhedong geese and Landes geese was methionine + cysteine, and the essential amino acids index(EAAI) ranged 79.46~88.28. However, the content of free delicious amino acids in Zhedong geese was higher than that in Landes geese. The two kinds of geese were rich in oleic acid. Compared with Landes geese, Zhedong geese had a higher level of monounsaturated fatty acids (MUFA) and lower level of polyunsaturated fatty acids (PUFA). The ratio of PUFA/saturated fatty acids in Zhedong geese and Landes geese met with the UK Department Health standard. The content of carnosine in Landes geese was higher than that in Zhedong geese, however, the content of anserine in Zhedong geese was higher than that in Landes geese. These results indicated that the nutritional value of Zhedong geese and Langes geese was very high.
