The port number is not after a semicolon. The ports are in red below:

Code:
66.81.1.252.53 > 64.147.113.139.28638

The rest I have to look at the tcpdump source for. I didn't see much explained in documentation.

The next number, 52313 is the DNS query ID which is used to differentiate queries. During the request this can be followed by a + or % to mean Recursion Disabled and Check Disabled bits are set, respectively. There are a few symbols that can be sent with the reply as well: AA*, RA-, TC|, AD$. Will have to look at the DNS RFC for those meanings.

What I was really curious of is that #/#/#. That seems to be the reply counts. AN/NS/AR (Answer, Nameserver, Additional Records).

The SOA record isn't really printed, just that it was in there, as "SOA", then all the A records which you see are the IPs associated.

Lastly you should have seen a (#) which would be the total length.
