This passage is Mulomedicina, II, 79, 16. The whole chapter deals with disorders of the bladder, nothing to do with gelding. The very old (1748) and, as far as I know, only English translation has the passage as III, 15 and renders it as:
But among the Sarmatians, whose Horses were greatly valued by the Ancients, use found out that if Animals be wrapped up in Cloaths from the Neck to the Feet, and be fumigated with live Coals put under them with Castor added to them, that so the Smoak of the Castor may with its Steam warm the whole Body and their Testicles, and if after the Coals are withdrawn, they presently walk up and down all covered, they will stale.
'Stale' means 'urinate'.

Strive mightily, but eat and drink as friends.
