In a recent discussion on Farmscape, swine management experts highlighted the effectiveness of moving pigs in smaller groups for smoother, more efficient handling. Dr. Jennifer Brown, an animal welfare specialist with the Prairie Swine Centre, explained that group size is a critical factor when it comes to easing the movement of pigs, whether it’s from pen to truck or through other handling processes.
Why Smaller Groups?
Dr. Brown noted that pigs naturally respond better to being moved in smaller groups, ideally with five or fewer animals. Large groups can lead to confusion, increased stress, and even physical injury as pigs crowd each other and struggle for space. By moving smaller groups, handlers can maintain better control, allowing the pigs to move more calmly and naturally.
“Pigs in smaller groups respond more predictably, which reduces handling time and labor,” said Dr. Brown. “Handlers have a better chance to guide and manage each group efficiently, and the pigs experience less fear and anxiety.”
Benefits for Animal Welfare and Operational Efficiency
Reduced stress is a major benefit for animal welfare, and it also enhances productivity. Pigs moved with lower stress levels tend to suffer fewer injuries and are less likely to fall ill, resulting in overall improved herd health. Lower stress levels also positively impact meat quality, as stressed animals can experience muscle fatigue that may affect the final product.
Moreover, moving pigs in smaller groups also allows handlers to work more efficiently. By reducing instances of crowding and panic, the need for corrections or pauses during the process is minimized, which can significantly cut down on labor hours and improve operational flow.
Implementing Smaller Groups in Practice
While some producers may see smaller group sizes as requiring more trips to complete tasks, Dr. Brown’s insights suggest that time spent in each trip is shorter, making up for the added number of trips. Smaller groups also require less corrective action, leading to an overall reduction in labor and handling costs.
For producers interested in implementing smaller group handling, it may be necessary to adjust alleyway sizes, gate placements, or pen layouts to streamline the process. Training staff on best practices for handling smaller groups can also optimize the transition to this system.
A Step Toward Industry Progress
As the pork industry continues to focus on animal welfare and operational efficiency, strategies like small-group handling become essential tools. They support better health outcomes for pigs and create a more sustainable and productive work environment for farm staff.
By taking a thoughtful approach to group size in pig handling, producers can address animal welfare, boost productivity, and ultimately improve the quality of their pork products.
