RE: [RC] Follow up on "tying up" episode - Karen Standefer
I have had a horse, in the past, that
wouldn’t respond to Se supplementation by mouth, initially, and had to be
injected. I would And, I’ve heard of several others in
the PNW with the same troubles. I would check with Heidi or Susan (or
another vet that you trust) about the injections. It’s my
understanding that injections are a viable way to supplement for some Se deficiencies
when they don’t respond to supplementation by mouth.

Please don't even think about injecting
your Buddy with Se (Selenium). It may kill him. A quote from my
ancient text: "Selenium is essential for domestic animals but the
margin of safety is relatively narrow. A low level of Se is essential
to prevent myopathies, liver injury and congenital abnormalities in domestic
and laboratory animals and poultry. ........High dietary Se is toxic to
animals and a defined set of signs and lesions has been established for acute
and subacute exposure to toxic concentrations in several species........The
minimum dietary level of Se, which results in accumulation in the tissues of
animals and ultimately produces signs of toxicity, is about 3 to 4 ppm of the
dry diet." Modern Nutrition in Health and Disease, 6th
edition; by Goodhart and Shils.
