Crowd gates are often one of the most used tools on a dairy. Not only do they save significant time for employees, but they also help reduce the stress associated with moving cows.
However, just like any tool, crowd gates can be used incorrectly and can sometimes negatively impact cow comfort and welfare. Carolina Pinzon, a Dairy Outreach Specialist with the University of Wisconsin-Madison, highlights the three most common mistakes she sees in crowd gate usage and provides practical strategies to avoid them.
Overcrowding the Holding Area
Occasionally, overcrowding the holding area happens, but Pinzon warns that prolonged overcrowding can negatively impact cow health, production, and welfare. This is especially concerning during summer when cows generate extra body heat and require sufficient airflow.
“Signs of an overcrowded holding pen include cows with their heads up, unable to plant their four feet on the ground, and looking restless and uncomfortable,” Pinzon says. “Short-term overcrowding can also result from misuse of the crowd gate, by employees pushing it too far forward and smashing the cows.”
To prevent overcrowding, Pinzon recommends balancing parlor and pen sizes, so cows spend no more than one hour away from their pens during each milking. Holding areas should allow at least 20 square feet per cow.
“If needed, a large pen can be divided into smaller groups,” Pinzon suggests. “While this means more trips to the parlor for workers, it significantly reduces the time cows spend in the holding pen. Additionally, short-term overcrowding can be alleviated by moving the crowd gate backward to provide more space for the cows.”
Being Careless
While dairy cows are typically gentle giants, they can be stubborn and slow to move. This, however, doesn’t justify using force. Moving crowd gates too quickly or applying electricity can cause unnecessary stress and fear for the animals.
Instead, Pinzon emphasizes the importance of calm and gentle handling. She advises guiding cows to the parlor without pressure or haste.
“Once the cows on one side of the parlor have exited, the crowd gate can be moved forward,” Pinzon says. “This regular adjustment is crucial to accommodate the changing number of animals and available space in the holding area. Automating crowd gates to move forward every time exit gates are open/lift can help reduce misuse.”
Pinzon recommends keeping crowd gates at least three feet from the cows to avoid pressing against their backs. She suggests using sound cues, like bells or ringing, to train cows to move forward, rather than relying solely on gate movement. If the gate gets too close, pull it back to give the cows more space before resuming forward movement. These practices promote a stress-free and productive environment for both cows and workers.
Workers Entering the Holding Area
Crowd gates are valuable tools for safely and efficiently moving cows toward the parlor entrance. However, when employees enter the holding pen to push cows, it can create unnecessary stress for the animals and put workers at risk of injury.
Pinzon highlights the importance of regularly training employees on proper cow handling and the correct use of crowd gates. She stresses avoiding the practice of entering the holding area to chase cows and instead maintaining a calm and consistent environment for the animals.
“Except for when loading the last cows of a pen and fresh cows, the door from the parlor pit to the holding area should remain closed during most of the milking process,” she adds. “This physical reminder is to discourage workers from entering the holding area. In addition, regular maintenance of crowd gates, prompt reporting of issues, and swift resolution of problems by management are crucial for proper gate function.”
Spotting these three common mistakes in crowd gate use and taking proactive steps to address them can significantly improve cow welfare, employee safety, and your herd’s operational efficiency. Regular maintenance, clear protocols, and proper training go a long way in preventing overcrowding and keeping things calm and stress-free for both cows and workers.
