Umbarger Cobboom is a high-fiber, low-energy ration component built to change how cattle look — not how fast they gain. Made from processed corn cobs, Cobboom provides effective fiber that increases rumen fill, body depth, and rib shape, helping cattle appear fuller and more dimensional without pushing additional fat or heat.

Cobboom excels in programs where control matters. It allows feeders to manage rate of gain, stabilize intake, and maintain structural soundness while still keeping cattle eating aggressively. Because it adds bulk without excessive calories, Cobboom is often used to hold cattle, slow them down, or soften the look of cattle that are getting too sharp or too aggressive on higher-energy feeds.

This product is not intended to be fed alone. Instead, Cobboom works best when layered into a complete ration, giving feeders another lever to pull when cattle need more fill, more depth, or more control.


Key Benefits

  • Increases rumen fill and body depth

  • Helps maintain a full, dimensional look

  • Supports intake consistency and rumen function

  • Helps slow rate of gain without pulling feed

  • Useful for holding cattle near ideal condition

  • Adds control when feeding high-energy rations

Choose Cobboom if:

  • Cattle need more body depth and rib shape

  • You want to slow cattle down without pulling feed

  • Cattle are getting too aggressive or sharp

  • You need to hold cattle fresh near their endpoint

Cobboom is not ideal if:

  • Cattle need more energy or gain

  • You are trying to add finish or fat cover

  • You are feeding very young calves without a structured ration

(In those cases, choose a higher-energy base feed and revisit Cobboom later.)
