NEW YORK (

TheStreet

) -- The quarterly portfolio holdings revealed after the market close on Monday from Warren Buffett and

Berkshire Hathaway

(BRK.B) - Get Report

showed a big gain in the Oracle of Omaha's exposure to

Johnson & Johnson

.

Buffett added roughly 18 million shares of Johnson & Johnson in the most recent quarter, according to the Securities and Exchange Commission filing.

Among major Warren Buffett portfolio dogs,

ConocoPhillips

(COP) - Get Report

continued to be sold by Buffett in the most recent quarter, with more than 5 million shares of the integrated oil company exiting Berkshire Hathaway's portfolio.

Buffett also unloaded another 1.5 million shares of

Kraft

( KFT). Buffett had been a noted seller of Kraft earlier in the year. Kraft was engaged in its purchase of Cadbury, over which Buffett voiced public displeasure.

There was only one new holding in the Berkshire Hathaway portfolio in the second quarter: information management company

Fiserv

(FISV) - Get Report

, of which Buffett added 4.4 million shares.

Fiserv is a natural for the Berkshire Hathaway stable of holdings. The bank technology company has a stable earnings profile, high return on capital, and relatively safe customer relationships. Even during the worst of the bank crisis, the biggest impact on Fiserv was a flat revenue line.
