Abstract:

As a part of fatty，PUFAS can influence animal reproductive performance. The appropriate ratio of dietary ω-6 and ω-3 PUFAs can increase animal survival rates，reduce the risk of preterm labor，and improve spermatozoa activity．Herein，the type，classification and metabolic transformation in vivo as well as correlations between dietary polyunsaturated fatty acids and reproductive performance of animals were reviewed．
