Nov 3 (Reuters) - Clinical research company Charles River Laboratories International Inc (CRL.N: Quote, Profile, Research) posted a 18 percent drop in quarterly profit, and cut its 2009 earnings forecast as pharmaceutical and biotechnology clients delayed their spending, sending its shares down 6 percent after the bell.

"We expect this situation (client spending) to worsen in the fourth quarter of 2009, which is the reason that we are reducing guidance for the year," Chief Executive James Foster said in a statement.

The company forecast fiscal 2009 adjusted earnings of $2.28 to $2.32 a share, down from its prior outlook of $2.35 to $2.47 a share.

Analysts on average were expecting earnings of $2.42 a share, according to Thomson Reuters I/B/E/S.

For the third quarter ended Sept. 26, the preclinical drug-testing services firm posted a net income of $37.3 million, or 57 cents a share, compared with $45.5 million, or 64 cents a share, in the year-ago period.
