Possible Vit D deficiency?

[FairyLights]

one of my youngsters has sweetitch, sadly. I have been applying benzyl benzoate and Switch but today,because he started to rub his tail when brought in this morning I have decided that he needs to wear his bug-rug.
Will enough sunshine get through for his body to make enough Vit D or will he need a supplement?
Thanks in advance.

The theory is that even only partial exposure for 30 minutes a day is adequate.

Otherwise, horses kept stabled for 23.5 hours over the whole winter would be deficient.

Also vit d is syhtensised differently in horses I think? Anyway mine has a body rug with good on under Neath and t times trousers... And no vit d problems here - the sunlight makes her skin blister.

Skratch by global herbs worked brilliantly for us of the other stuff doesn't help

Thanks for the replies. Ned is out this afternoon minus rug getting some sunshine. Best way I think, rug will be back on later.
