As i said, the simple fact that the horse even HAS rainrot, lice, etc would tell us that no matter what the horse is eating, he is still deficient in vit. A. therefore, the treatment recommended would have no ill effect since it is making up a deficit plus providing stored Vit A for later use.
Also, consider this....
If we know that green grass is very high in vit A and horses eat it by the tens of lbs daily.....
yet all year we typically feed our supposedly well formulated feed no matter if we have green grass or are feeding hay which is proven to have limited to no vit A within a few months of cure,
Just think how much vit A the horse is missing from the green grass when eating 2 or 3 month old hay this time of the year even tho he is still eating his formulated feed. Not all feeds are created equal either. Clearly, the horse is at a deficit from the summer months when he can graze green grass. There can be no dispute.
Further, if he then develops rainrot or lice etc...we can clearly determine that the vit A he is receiving is nowhere near enough to meet his actual needs since his body had some stored in it as well for a period of time on TOP of his daily feed provided amount.
I would submit that anytime a horse is on cured hay, especially this time of the year when its been sitting awhile, supplementing vit A even on top of many of the formulated feeds out there would be prudent. Since it is stored in the fat, 5 cc once a month seems to work perfectly well IME.
Also, Farnams mare plus has around 3 times the amount of vit A as most feeds and it is typically fed WITH another feed ;) they must know something eh?
It has been suggested than the recommended daily allowance of Vit A for equines is actually too low for horses on cured hay when it may be fine for horses on green grass. Simple deductive reasoning and proof through trial tells me that this is clearly true and I will not easily overdose my horse on vit A by supplementing once a month during hay feeding seasonfor prevention and once a week for treatment of a current visible deficit.
Just food for thought. Ive thought about this alot and know from experience that it is true.
