Come on folks, let’s try to make some sense of what is going on here. I received correspondence from a producer that, among other things, was giving one tenth of a cc of MU-SE at birth. For starters, the dosage is one cc per 200# of body weight for weanling calves. Not approved for sheep. We are overdosing on selenium immediately and each cc of the product contains 68 units of Vitamin E so we are giving 7 USP units of Vitamin E when the recommended dose is somewhere between 300 to 1,000 units. Now I am not singling out this one instance, I encounter these situations almost daily with these two products. Someone has done a good sales job.

BO-SE is similar, it is recommended one cc per 40# in lambs and that is the minimum weight it is to be given, read the label folks. It also has a whopping 68 units of Vitamin E per cc. It’s not recommended for pregnant ewes due to what is probably a failure to run tests necessary for clearance. Use is common in animals in advanced pregnancy.

What’s the most economical and safest answer? Feeding iodine, selenium and Vitamin E thru the salt. Big Gain Feeds has this product complete, or if you do not live in an area serviced by them, we have products #6249 and #8770 that can be easily mixed with salt, #6249 contains Vitamin E, #8770 does not.
You certainly don’t need Vitamin E when animals are on pasture or early in fall when feed stuffs still retain their Vitamin E. These products provide iodine as well and complete you entire mineral needs for breeding sheep.

What’s the take home? Selenium and Vitamin E should be provided in the ration as a safer and more cost effective route of administration.


About Ask-a-Vet Sheep

Veterinary services, procedures, biologicals, and drugs mentioned in this publication represent the personal opinions and clinical observations of the contributing author. They are in no way intended to be interpreted as recommendations without the consent of the producer’s own practicing Veterinarian. We strongly urge that producers establish a patient-client-veterinarian relationship that allows extra-label use when there are no drugs approved for treatment or if approved drugs are not effective. This procedure allows veterinarians to go beyond label directions when “prudent use” is necessary. The limited availability of drugs and biologics in this country is a major factor in restricting the growth of the sheep industry and allowing producers to compete in the world market place.
