This thread probly isnt in the right section but wasnt sure where to post it. Im just curious to know if anyone knows much about this disease, like is it common, does it affect all ages or just young horses etc? All i really know is that its caused by a lack of calcium growing up... Im asking because when i got my horse i noticed he has a hard bony lump between his eyes that hasn't gone away or gotten bigger. I've had the vet out and they said he might have copped a kick in the head at some point in his life. (hes 6) They also reckon if it gets any bigger or i notice a change in behaviour (agression etc) i need to take him to the vet for x-rays as it might be putting pressure on his brain... It hasnt changed but i wonder if Big Head Disease could be the cause? Ive bought calcium powder and cut his bran off (apparently it stops calcium absorption) and no change but then again if hes had it for years it could just stay that way... I think another symptom is lameness, hes definately not lame but he does have a club foot, does anyone think it could be related? Sorry for the ramble but its been on my mind for a while now and im really keen for more info.
