Reduced farrowing times with uterotonic, Vetrabutin
Different super script means statistically significant differences (Source: D. Mota Rojas et al., 2005)
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
Inflammation of specific udder segments can occur at any stage during the lactation.
When milk-release is impaired by mastitis in one or more udder segments, there is the threat that FIL (a protein) will be released: when the concentration of this protein in the udder milk in creases, milk production is suppressed and eventually milk flow will stop.
Because hypothermic pigs
require more time after birth to ingest adequate colostrum
generally ingest less colostrum
SCOTLAND - Results from a recent survey indicate that more than 60 per cent of slaughter pigs suffer some degree of Ileitis during their lives. The findings, collected from a comprehensive blood-testing programme carried out in Scotland, provides valuable information on the disease and how control methods could be improved.
