Can a cow get sick from eating cactus?

Cows can indeed get sick from eating cactus, especially if they consume large quantities of it or if they ingest certain types of cactus that are known to be toxic. Some cacti contain high levels of alkaloids, saponins, and other toxic compounds that can cause a range of health problems in cows. These compounds can irritate the cow's digestive tract, leading to symptoms such as vomiting, diarrhea, and abdominal pain. In severe cases, cactus poisoning can result in kidney failure, liver damage, and even death.

In addition, the spines and thorns on some species of cactus can cause physical injuries to cows, such as cuts and punctures, which can lead to infections and further complications. It's important for ranchers and farmers to be aware of the potential risks of cactus consumption and to take steps to limit their cows' access to these plants, especially during times of drought when other forage options may be limited.
