On 14th Aplil i noticed two of my Lley ewes both with twins struggling to stand on their feet, mainly front feet, buckling under at the joint. A quick word with my vet and he suspected Grass Staggers. On the 15th i injected under the skin 75ml of magniject9 as advised by the vet. I moved them with their lambs into the barn with fresh good hay and feeding them twice a day with coarse mix, today one of the ewes is showing signs of improvement but still not good the other is still struggling to stand. I was wondering how long it can last? If i should give more magniject if so how much? is hay and feed ok or do they need to be on grass? Many thanks in advance
