| Abstract: | Five youth bulls of Sinan yellow cattle were slaughtered to ascertain the meat nutritive property by analysizing their meat general composition, calcium, phosphorus, energy, fatty acids and amino acids.The findings indicate that the contents of protein and fat are 22.95%, 4.94% based on fresh sample, respectively. The ratio of unsaturated fatty acid (UFA) to total fatty acids (TFA) is 42.50%, and the ratio of essential amino acid to total amino acid (EAA/TAA) is 46.30% (tryptophan excepted). Therefore, the ... |
