Love this quote! I might have to use it. We live in the fescue kingdom here. We had a fellow rancher kill all his K31 and replace it with MaxQ. He took several years. He did a bunch of talks for the extension on his improved gains and benefits, he is an outstanding record keeper. Last year with the drought, he had to move some cows to a new field he had rented and not converted yet. The pictures of the cows affected were horrible! Several lost their hooves, and he had to put several down. To me, the loss of those few cows can not compensate for the gains he got by converting. If our cows do not make it on fescue, they go. I have a few that I think are borderline, they still have not shed their hair and are the first to the water to cool off, but they still give me a good calf every year so they stay.
I'm still in the dark.....he had to move them to a field that had Ky 31 fescue and they couldn't handle it? Explain.
Because he had converted his pastures to a novel free fescue, his cattle, I assume, lost the resistance to ergovaline that K31 produces. If I remember correctly, the cattle that were affected the worst were newer heifers, just two year old females nursing calves, so they had not been previously exposed to K31 since the pastures had been converted for a few years already. When they were moved from a endophyte free pasture to a hot pasture, they could not handle it and lost switches and a few lost their feet. It is a vaso-restrictor, so it causes the blood vessels to restrict, which is the worst thing in summer. One of the first signs you see is the cattle are tender footed when they first get up, like their feet are asleep. They soon walk out of it, so one thinks it is nothing. But it slowly gets worse. I am not sure if he had any other grasses in the field, but considering it was a dry year with a severe drought for MO, I am pretty darn sure there was no to very little clover. I had the same problem last year, lost most of my clover, but I had rye and OG out there to help water down the fescue. I can tell you that the fescue was about the only thing that survived the drought, and I had to go back and put in a bunch more clover, OG and rye last fall to get the mix I want. People who graze fescue have a love-hate relationship with it. You just have to manage it.
