Abstract:

In the present study, a total of 60 Jinhua piglets from the same batch were fed with commercial diets under the standard management. Four Jinhua pigs were randomly selected and slaughtered at 45, 90, 150 and 270 days of age, respectively, to determine the ribeye areas, and longissimus dorsi muscle and serum samples were collected to determine the content of amino acids and their derivatives. The results showed that the ribeye areas of Jinhua pigs significantly (P<0.05) increased with age. In the longissimus dorsi: essential amino acids content and total amino acids content significantly (P<0.05) increased first, then significantly (P<0.05) decreased and remained stable after; while nonessential amino acids content increased significantly (P<0.05) first, decreased significantly (P<0.05) later and then increased significantly (P<0.05). In the serum: essential amino acids content remained stable first, and then increased significantly (P<0.05); nonessential amino acids content decreased significantly (P<0.05) first, increased significantly (P<0.05) later and then remained stable; total amino acid content decreased significantly (P<0.05) first, then increased significantly (P<0.05). Most of the amino acids contents in muscle and serum were positively correlated with ribeye areas, where the contents of arginine, valine, isoleucine and leucine contents gave a strong positive correlation with ribeye areas, but glycine content in the muscle and serum was negatively associated with ribeye areas. In summary, the amino acid profiles in the muscle and serum of Jinhua pigs presented developmental changes, and arginine, valine, isoleucine and leucine contents were positively correlated with muscle growth.

Key words: Jinhua pigs, amino acid profile, ribeye areas, muscle growth, developmental changes
