[QUOTE="Ebenezer, post: 1732166, member: 24565"] If she is wormy, good chance they are all wormy. Totally wrong. Worm resistance is an inherited trait and usually 10% of the livestock are producing 90% of the eggs on pasture. Select and cull. First calf heifers are the most vulnerable class of cattle in this discussion. The lack of full immunity and the pre-birth hormone changes set that up. We have not wormed anything over 3 YO in decades. I did not worm calves this year and did FECs at weaning. Less than 25% needed worming by the threshold limits. Those "need-to" animals got marked to go. [/QUOTE]
