This year, none except possibly a very small drop in consumption-but remember we are feeding the toxin-containing stuff at a fairly low level-about 20% of the ration.

2 years ago we had dry mature cows lay down and die before we figured out the cause. After we changed how we fed it, we still seemed to have an inordinate amount of various health problems-no one big thing, but an assortment of things that could be lumped under "poor immunity response". Retained placentas, displaced abomasums, poor cleaning, weak heats, higher than usual levels of pneumonia, etc. Hit old cows the worst, really raised our cull rate. In the past, without the tests, I would have attributed it to an awful run of bad luck.

For your client, he needs to get some tests on the silage. With any luck, it will show up clean and he'll have to look elsewhere....but he will have one possible cause eliminated. The tests are expensive and take 2 weeks to get results, "here".
