In pigs, ejaculate is expelled in fractions, mainly the sperm-rich fraction (SRF) and the post-
SRF (PSRF), which differ in both sperm content and origin. In addition, intra-ejaculate …

Metabolomic approaches allow the study of downstream gene expression events since
metabolites are considered as the products of cell signaling pathways. For this reason, many …

Background Metabolomic approaches, which include the study of low molecular weight
molecules, are an emerging-omics technology useful for identification of biomarkers. In this …

Donkeys are indispensable livestock in China because they have transport function and
medicinal value. With the popularization of artificial insemination on donkeys, semen …

Simple Summary In the freezing process of boar sperm, there are obvious differences in
