Signs of excessive intra-uterine pressure during birth:
Slow start of breathing in newborn piglets
Ruptured, profusely bleeding umbilical cords at birth
Strangulation of the piglets by the umbilical cord
Uterine spasm, retarded birth
A typical situation: farrowing was planned for the Thursday but many sows have already farrowed by Tuesday. Weak piglets lead to low milk-release of the sow.
Sow herd vaccination, i.e. against influenza and other viruses that can be transferred from the sow’s blood stream through the uterine blood supply thereby breaking through the uterine barrier: PRRS-virus, Circovirus, Parvovirus
Good body condition and fitness of the sow
