Temperature down but

[joy]

The youngster (5yo) has a slightly low temperature but he is eating and behaving normally except he has no get up and go. For a TB on the feed he is getting he should be jumping out of his skin but he is just so run down.
Before I get the vet I might administer a blood tonic.
Any ideas ?

Not all TBs are full of fizz. Is he normally fizzy and cheeky? My TB has been quiet since we got him as a 4yr old - nothing wrong with him, he just doesn't see the point in rushing to get anywhere (unless it's to get food!)
Is he being kept warm enough? If he's cold that could account for the low temperature and he'd be using up energy to keep warm... just some thoughts.
