Fat deposition deficiency is critical for the high mortality of pre-weanling newborn piglets

Background The high mortality of pre-weanling piglets is a dominant challenge which severely restricts the development of pig industry. A number of factors including nutrients imbalance and temperature variation during postnatal period of piglets have been reported to closely associated with the high mortality of postnatal piglets. This study aims to find out the relationship between fat deposition and survival of newborn piglets.
