We've got one cow that's a mudder, but she's like that winter or summer. Cows that are not adapted to endophyte have problems, that's a given. But if you select calves that perform well on endophyte they'll continue to do well winter or summer. Our cows generally get fat over the winter on nothing but stockpiled fescue. They tend to carry almost too much condition during the summer, but they wean large calves and breed back. We had a heifer last year that I really wanted to keep. When we pulled them off pasture and gave them a little grain for weaning she slicked right out. She went down the road. We don;t keep anything that needs supplements to carry condition and breed back.
I know of many herds that brought in cattle from different areas that had never been on fescue and the majority of those cattle had problems. A while back a woman moved to Cape G from CO and lost her entire herd to endophyte toxicity.
We keep a good level of legumes to help dilute the endophyte, but thses cows are adapated and selected to work on the forage base available. When we buy breeding stock we insure they were raised on the nasty stuff.
It's worked for us.
