Abstract:

Proline is a cyclic α-imino acids,meanwhile it also can be considered as a functional amino acid for mammals and plays an important role in protein synthesis,organism metabolism,wound healing,anti-oxidant and immune reactions. The studys have found that extra dietary supplementation of moderated proline has great significance in improving the growth and development of conceptus,piglets, embryo,mammary gland and placenta of sows,at the same time it also can prevent intrauterine growth restriction. The author reviewed structure characters and physicochemical properties,anabolism and catabolism of proline,and especially focused on its effects on the reproductive performance of pregnancy sows and potential regulation mechanism aiming to provide some help for the researchers in the field of sows.

Key words: proline; sows; biosynthesis and metabolism; reproductive performance
