[QUOTE="Ebenezer, post: 1336765, member: 24565"] We tried the Safeguard blocks one time and we had a single cow eat about all of one block and a number of cows that never tried them. That was years ago. since then, from reading, it seems that some cattle can develop resistance to worms when mature. So we quit worming anything over 3 YO about 10 or 12 years ago. We worm young stock but more therapeutically and really do not see a lot of signs of wormy cattle. Maybe I ought to do like we do the sheep and cull anything that needs worming and quit the treatment of all under 3 YO. The sheep sure seem to have benefited from the selection pressure. [/QUOTE]
