Don’t Stress Out Your Wean Pigs This Fall

Stress isn’t good for any stage of the pig’s life, but weaning is certainly a time where lowering stress on the pig is not just a good idea – it’s critical. From the right diet to the right environment, it’s essential that employees are ready to help pigs get off to the best start possible.

“Those piglets are used to having full bellies coming off of their mom at weaning, and so as they transition into the nursery, being able to fill those stomachs and digestive systems with food is very critical,” said Joel DeRouchey, professor at Kansas State University, at the Annual Swine Conference hosted by Carthage Veterinary Service. “Once pigs eat more, they’re going to have a better average daily gain the rest of their lives, and we know that their digestive health is going to be better.”

How Clean is Clean?
When it comes to getting pigs started right in the barn, one area that needs talked about more is sanitation, DeRouchey says.

Although it’s clearly not overlooked, he says studies show opportunities for improvement.

“There are many ways that we clean barns after a group leaves and before the next set comes in,” he says. “I think we need to get back to the basics, making sure not only the pens are clean, but particularly focusing on any rubber or plastic mats that are used group to group, and especially the watering devices, are also clean.”

Data has shown that the watering device, before sanitation, has some of the highest counts of E coli, he points out.

Swine Industry Advances: Biodigesters Lower Emissions and Increase Profits

Video: Swine Industry Advances: Biodigesters Lower Emissions and Increase Profits

Analysis of greenhouse gas (GHG emissions) in the Canadian swine sector found that CH4 emissions from manure were the largest contributor to the overall emissions, followed by emissions from energy use and crop production.

This innovative project, "Improving Swine Manure-Digestate Management Practices Towards Carbon Neutrality With Net Zero Emission Concepts," from Dr. Rajinikanth Rajagopal, under Swine Cluster 4, seeks to develop strategies to mitigate greenhouse gas emissions.

While the management of manure can be very demanding and expensive for swine operations, it can also be viewed as an opportunity for GHG mitigation, as manure storage is an emission source built and managed by swine producers. Moreover, the majority of CH4 emissions from manure occur during a short period of time in the summer, which can potentially be mitigated with targeted intervention.

In tandem with understanding baseline emissions, Dr. Rajagopal's work focuses on evaluating emission mitigation options. Manure additives have the potential of reducing manure methane emissions. Additives can be deployed relatively quickly, enabling near-term emission reductions while biodigesters are being built. Furthermore, additives can be a long-term solution at farms where biogas is not feasible (e.g., when it’s too far from a central digester). Similarly, after biodigestion, additives can also be used to further reduce emissions from storage to minimize the carbon intensity of the bioenergy.
