Francesco, You may want to look at relayd from OpenBSD project. The last time I looked it was able to load-balance DNS. If you are looking for an appliance solution, the pfSense project (firewall) had ported relayd and gave it a GUI - though the DNS LB may not be in the GUI. Best is it is free.

I read something about HAProxy but it does not manage udp connection and the interesting security proxy/balancer DnsDist does not pass original client ip for Bind-DLZ... Thank you, regards!
