Senna Beans Invasives - 08/27/19
These are bad news. Poisonous to cattle...
Invasive weed. They really propagate when the weather is wet as it has been for two years.
This ranch has them pretty bad. These are about 14' tall. Cutting them before they go to seed. They really need to spray them. But since they pay me to shred them, I can't well complain.

After a few rounds...

Y'all have these?
I'll probably get to the back of this ranch tomorrow. I'll be surprised if they aren't much thicker back there. I'll update with a photo of them REALLY thick.

Toxic Agent
Sennabean plants contain sesbaimide, which is concentrated in the seed. The green and flowering plants are unpalatable; only the mature, dry legumes and seed are consumed. Animals raised in pastures with the plant learn to avoid it and are seldom poisoned. However, naïve cattle, goats or sheep placed on pastures containing dried plants in late fall and winter are often poisoned. Observations of field cases indicate that seeds are much more toxic when they first mature than 2 or 3 months later.
Signs of Livestock Ingestion
Signs of poisoning occur within 1 or 2 days after ingestion and may include: Depression; Diarrhea; Weakness; Rapid heart rate; Labored breathing; Death.
Clinical signs progress rapidly; sick animals often die within 24 hours. Diagnosis is confirmed when seeds and/or seed fragments are found in the rumen contents.
