The hot, humid days of summer often bring the challenge of coccidiosis in pre-weaned piglets in the farrowing barn, but that challenge has now become more prevalent year-round, according to Dr. Laura Bruner with the Swine Vet Center in St. Peter, Minn.
While biosecurity remains the best option for managing Actinobacillus pleuropneumoniae (APP) outbreaks in swine finishing barns, the recent APP outbreaks in the Midwest has spotlighted biosecurity gaps in this phase of production, according to Swine Vet Center veterinarian Dr. Ethan Spronk.
Herd closures to eliminate porcine reproductive and respiratory syndrome (PRRS) are on the increase due in part to the virulent variant identified as PRRS 1-4-4 L1C.
During winter, swine facilities usually operate at minimum-ventilation rates. But if those rates aren’t correct, high humidity and excess gases will build up leading to increased disease and reduced growth rates.
All types of supplies and equipment enter a hog farm, putting the operation at risk of a disease outbreak. Improved biosecurity protocols with layering help minimize the risks, reported Erin Kettelkamp, DVM, Swine Vet Center.
