A recent study suggests Porcine Epidemic Diarrhea virus (PEDv) can be carried in livestock feed. The findings were publishing in a recent issue of the pre-reviewed BMC Veterinary Research. Click here to read more.
Even before the study confirmed suspicions and shed new light on how the disease may be transmitted, Kansas State University’s Applied Swine Nutrition Team urged producers to be knowledgeable of feed ingredients and the potential risks associated with their use in swine diets.
“Some swine producers are choosing to take steps to reduce their risk of PED virus being introduced through feed ingredients,” the team wrote in an update here.
The team suggests producers apply one – or more – of the following steps:
- Test porcine-derived products for PED before using them in diets and only use after they’ve been verified as PCR-negative for PED virus
- Replace porcine-based products in diets with bovine-based products (i.e. bovine plasma to replace porcine plasma)
- Consider removing all animal proteins, except milk products, from the diet
The team added, “Because the implications of PED virus infection are much greater for sow farms, some producers are choosing to not use any porcine products in creep feed or in gilt multiplication feed, while using porcine products tested free of PED virus in off‐site nurseries or in wean‐to‐finish production.”
Additional nursery diet options, also available at www.KSUSwine.org, range from removing all porcine-derived feed ingredients to removing specific protein-based ingredients from nursery diets. The team suggests using protein sources such as fermented soybean meal, soy protein concentrate, whey protein concentrate, skim milk powder, and poultry meal.
As always, producers should involve their herd veterinarians, nutrition advisors, feed manufacturers, and ingredient suppliers to determine the best protocols for their herds.
