There getting silage but wouldn't be classed as ad Lib. Wasn't able to get it tested. Had fluke issue when Rams went in. Dosed with a certain dose that was told would mix dosing up so not to get resistant to other one. But turned out the stuff I was sold had the resistant ingredient in it so was waste time. 14 ewes died in just under 3 weeks at tupping then when scanned had another 30 empty as result of it. Sent ewe off to lab when I could and came back with bad liver fluke
