We are a chalk, dry farm and blood tests have proved that we are deficient in colbolt and Selenium and so we drenched lambs monthly from end of June - 1st dose done this week - until they go for dispatch or market.
What’s your view on dealing with farms with extremely high molybdenum & trace elements. We have to supplement regularly but always fear toxicity to selenium. Any advice on this?
@@raymondwarrington9950 hi there, I'd want to know a bit more background before actually giving advice, but there are injectible b12/cobalt supplements which contain no other trace elements, so if you were worried that background selenium or levels were already high, you could use these to avoid adding extra selenium to the system (pretty much all cobalt drenches and boluses also contain selenium unfortunately). It would be very very rare for lambs to die from selenium toxicity unless they were being supplemented with it, regardless of the levels in the ground. Hope that makes sense!
Thank you great videos 👍👍👍👍👍
Excellent!
