After our disastrous last year with Barberpole worm losses I looked into methods of parasite control. I saw that some people were using copper boluses and wire in goats and cattle for worm control. Since most sheep people practically have a heart attack if their feed contains any copper, I investigated copper requirements and health risks in sheep. Sheep DO require copper, just not as much as goats and cattle.
The required range of copper for most sheep is minimum 8ppm and maximum of 15ppm. the range required by the sheep depends on whether they are pregnant, lactating, or dry. Bred ewes require higher amounts of copper (12-15 ppm) for the developing fetus. Lactating ewes require slightly less (10-12 ppm) but more than open ewes since they are putting some of the copper into their milk for the lambs. Lambs also require a slightly higher amount of copper than the 8 ppm minimum since they are developing growing skeletons and bodies. The type and amount of minerals in your hay depends on where it is grown. You can do soil tests through your Extension Agent to determine the minerals in your pasture soil.
I think that the lack of any copper in their diets last year may have contributed to all the deaths in the flock. Our entire lamb crop (15 lambs) died over a eriod of 4-6 weeks after being integrated with the adult ewe flock. While that may have been because the lamb pasture had a minimal Barberpole count and the ewe pasture had a higher count, the lack of copper probably gave the lambs little to no resistance to parasites when exposed to them. The lambs were all about 5-6 months old when turned in with the adut ewes. We also lost 8 adult ewes and several adult rams.
We had been feeding pellet feed with no copper in it for the past 18 months. The protein count in that feed was 10%. Now we have switched to a pellet feed with a copper range of 8 ppm to 15 ppm, and a protein content of 15%. We are hoping the copper ratio will help with worm resistance this year. We also give a mixture of corn and barley on top of that. Corn and barley are low in copper, but higher in Phosphorus and Potassium which helps the processing of copper. Neither of those grains is appreciable in Selenium. To be on the safe side, we vaccinate with Selenium (Bo-Se) before turning in the ram with the ewes. This overcomes any problem with low Selenium in newborn lambs.
I am also utilizing the Poopa's lye method worm protocol from the internet. We burned oak in our fireplace all winter and have been saving the ashes. I will sift them and mix them with their loose salt mineral mixture, also as recommended by Poopa. Another test on using the lye worming process was run by Harmony Shepherdess using fecal counts before and after worming. Whoe she used goats, the tests were quite interesting. She also had the fecals checked by her vet before and after worming. She used 1 tsp lye to 2 cups water mixed into 2 gallons of grain. This recipe is a stronger lye solution than used by Poopa, but had quite impressive results.

I am going to continue using it. The only problem I see with this method is that you can't control the amounts each individual sheep eats. Hopefully between the lye worming, and the additional copper in their feed, my sheep will not be as susceptible to worms this year.
I will be worming again before I leave for California.
I might try using half goat mineral and half sheep mineral as well like Mike suggests.
