[QUOTE="Lucky_P, post: 1717367, member: 12607"] I haven't seen a grub in a cow since sometime back in the late 1970s. I'm sure they're still out there somewhere, but widespread use of macrocyclic lactone (Ivermectin-class) dewormers has mostly eliminated them over large areas of the country - to the extent that any concerns about migrating grubs and issues associated with treatments are largely dismissed in most areas, anymore. The biggest issue with dying migrating grubs causing paralysis or bloating was back in the day when we were still using pour-on (mostly organophosphate) insecticides like Ruelene, coumaphos, diazinon, etc., for grub control. It's been so long since I even thought about them, I'm still unable to pull the name of one out of the deep dark recesses of my cranium, that we used to use... you had to be careful using it on Brahman-influenced cattle... it'd knock 'em off their feet, and killed more than a few. Seems like it started with a F or a T... The bloat/paralysis issue is greatly reduced with the macrocyclic lactones (Ivermectin type dewormers) by comparison. [/QUOTE]
