Effect of reducing crossfostering at birth on piglet mortality and performance during an acute outbreak of porcine reproductive and respiratory syndrome
نویسنده
چکیده
Methods: During the first 10 weeks after an outbreak of acute porcine reproductive and respiratory syndrome (PRRS) in a herd but prior to implementing McREBEL management, crossfostering was performed only within 24 hours of birth; however, because the manager was sizing and sexing all litters at birth, > 85% of piglets were being raised by a foster dam. Under the McREBEL protocol, crossfostering practices were changed so that only the minimal number of piglets needed to fill functional teats (fewer than 15%) were moved between litters.
