I Let out 30 saler bullocks 2 months ago and ever since they have been dropping weight sides going in and rips very slightly visible I know cattle are set back for around 3 weeks after coming out of winter housing but I’m a bit concerned,grass quality is good,maybe a bit on the strong side but that should hold it in them. There grazing alright and weather is dry enough the only thing I could put it to would be stomach worms so they will be given ivermectin tomorrow but I would still doubt it would have that effect another would be a copper deficiency which does have symptoms shown. Any ideas?
