Does every horse need a balancer?

Good day, fellow enthusiasts of equine nutrition. I've been pondering a question that's been swirling in my mind lately, and I'd love to hear your thoughts on it. The topic at hand is: Does every horse necessarily require a balancer in their diet? I understand that balancers can offer a convenient and comprehensive way to ensure horses are getting all the essential nutrients they need, but is it a universal necessity? Are there any scenarios where a horse might thrive without one? I'm particularly interested in hearing about any personal experiences or insights you may have on this matter. Let's delve into this topic and explore the pros and cons of incorporating balancers into equine diets.
