To help pig producers plan appropriate strategies to manage post-weaning diarrhoea (PWD) without zinc oxide, Elanco is offering free diagnostic testing to identify the types of pathogens and strains present on farm that can cause the disease.

Jack Fellows, Elanco swine sales lead explains that around 54% of farms in the UK have PWD and the F4 and F18 strains of enterotoxigenic E. coli (ETEC) are responsible for the vast majority of cases, between 50 and 80%.

“Other strains of E. coli can be responsible for PWD and pathogens such as rotavirus, campylobacter and cryptosporidium can also play a role, especially if gut integrity is already compromised by ETEC infection,” says Mr Fellows.

Despite zinc oxide continuing to be available in the short-term, he says producers must start thinking ahead and begin integrating new tools to manage the disease now.

“Knowing exactly what you are dealing with by identifying the likely causative agents on-farm, is important to develop an effective prevention programme. In the absence of zinc, which has served as a silver bullet, multiple measures will be needed,” he says.

For many herds, the options available will include vaccination with Coliprotec™, an in-water oral vaccine that protects piglets against the two main strains of E. coli that can lead to PWD. Piglets can be vaccinated from 18 days of age with onset of immunity within seven days, providing early protection against the disease.

“Vaccination offers a good return on investment, particularly when used in tandem with other measures such as good hygiene and nutrition. Coliprotec™ is helping pig producers reduce the need for zinc or antibiotics, while making a positive contribution to overall health and we’re seeing a growing number of herds integrating the vaccine into their PWD prevention protocols,” he explains.

To determine the suitability of vaccination, producers can access Elanco’s free diagnostic test via their vet practice.

“Request a test at the first onset of PWD, which typically occurs in the first three weeks after weaning. If you have a positive test for the F4 or F18 strain of E. coli, it’s likely this will remain or increase in future batches of piglets,” says Mr Fellows.
