Abstract:Serum concentration of free amino acids was determined in suckling pigs. Body weight was recorded before the pigs sucked milk in the morning of postnatal d 1, 7, 14, 21 and 28. Precaval vein blood samples were obtained from those chosen pigs for analysis of serum amino acids. Serum concentration of arginine increased sharply (60.44%, p < 0.05) during postnatal d 1 to d 7, and decreased progressively (38.16%, p < 0.05) from postnatal d 7 to d 21, and gradually increased (22.73%, p < 0.05) from d 21 to d 28 after birth. Serum concentrations of isoleucine and leucine continued increasing (p < 0.05) from postnatal d 1 to d 28; while that of methionine, phenylalanine and tyrosine decreased progressively (p < 0.05) during the same period. Serum concentrations of histidine and lysine changed in a waveform-like way within postnatal 28 d and decreased (p <0.05) from d 1 to d 7, and d 14 to d 21, and increased (p < 0.05) from d 7 to d 14, and from d 21 to d 28 after birth. Serum concentrations of threonine, valine, alanine, aspartate, glutamate and glycine increased (p < 0.05) from 1 d of age to 14 d of age and then decreased (p <0.05) from d 14 to d 28 of life. Serum concentrations of proline and serine increased (p >0.05) during postnatal 7 d and decreased (p < 0.05) from postnatal d 7 to d 28. The developmental changes of serum concentrations of methionine, phenylalanine and tyrosine were expressed in linear way (p< 0.05); that of isoleucine, threonine, alanine, glutamate and glycine in quadratic way (p < 0.05); that of arginine and serine in cubic way (p < 0.05) and that of histidine and aspartate in quartic way (p < 0.05), respectively.
