blindness


mate of ours has a full et sir christopher x starbuck full bro to our heifers.
his bull is about 18 months to 2 yo and has just gone blind.Merck vet manual informs me could be
1. genetic - progressive blindness but his 3 full sisters appear fine to date.
2. selenium poisoning from eating plants full of selenium(altho havent been able establish what these might be)
3. vitamin b or a deficiency.
He has been running on "good " dryland feed.

Last year in the drought I had a just weaned bull go blind on me and we got the vet out who couldnt find anything wrong with him and treated him with a course of b complex and A.D +E shots and put him back on milk .took him couple of weeks to get eyesight back.
Any thoughts anyone???

Re: blindness


Here's a little something I found on this subject,

" studies had implicated excessive exposure to UV-B radiation in actinic keratitis, an inflammation of the cornea--the transparent, slightly curved tissue that focuses light entering the eye--also called snow blindness. UV-B may also reactivate herpes simplex virus infections in the cornea of the eye, a potentially blinding condition.

The long-term effects of increased UV-B radiation on the eye also include cataract (clouding of the lens) as well as damage to the conjunctiva, the lining of the eyelid "

vitamine B deficiancy is ussually associated with shaking of the eye, the eye sort of vibrates.
It could perhaps be a case of physical damage to the eye ?

Re: blindness


Dont think there is any physical damage to his eyes.Roger just said that he'd been running in a paddock with some dry cows and when they went to shift him he fell over the 4 wheeler then ran smack bang into a gum tree then rolled himself up in a fence.
Our calf (4 months) had no visual sign of damage.He fell clean over the grain trough then ran swmack into a paling fence the day I noticed there was something wrong with him. The vet said he was definitely blind. I insisted on a coarse of a heavy dose of vitamins and he came good after a week or so.

oh forgot to say reason I insisted on vitamins was that had read in morrisons feeds and feeding that insisdences of blindness had been found in holstein calves that had been fed a principally straw diet(lack of green feed)
