Mr Arbuthnot said: "I just suggest the Bill should, as the Welsh equivalent Bill does, make it clear the word horse includes ponies and jennets."
Liberal Democrat David Heath intervened and said: "I do think the normal definition of a horse would involve anything which was of the same species as a horse, which is to say equus ferus caballus, which ponies and jennets are.
"The reason donkeys are separately identified is because they are not the same species - they are equus africanus asinus if I remember correctly, so they have to defined separately."
Mr Arbuthnot said: "You are almost certainly right. It is quite clear from your intervention that you know far more than I do about these matters - probably most matters."
He added: "If this amendment is unnecessary and we don't need to define what a horse is, as you suggest, then I will move on."Councils! What would we do without them?
