Trocar And Cannula Use In Cattle Sometimes cattle on lush fall pastures bloat under certain conditions. You may need to remove them from the pasture, but don’t round them up too quickly. They may bloat more readily from movement and jostling of the rumen. If you have to open up the rumen with a trocar, you can pour the mineral oil in through the trocar cannula. If it’s frothy bloat, foam may plug your stomach tube or trocar cannula. Make sure the gas is still coming through.

You may have to wiggle and blow on the tube to clear it. With a trocar, the cannula stays in and you can push the trocar back through it to remove the blockage, explains Carl Dahlen, beef specialist with North Dakota State University. When we move cattle into risky pastures, there will be some that bloat right away, but usually the greatest proportion will occur a couple days after they were put in, warns Carl Dahlen, beef specialist with North Dakota State University. Many people think the first few hours are the most crucial, and that cattle will be fine if they don’t bloat that first day.


Trocar and cannula have been used for many years for the emergency release of rumen contents and gas in bloat. The anatomical location for incision of skin by trocar and canula is that at flank of cattle behind of last rib.
