Supplement dated March 12, 2007 to Prospectus dated May 1, 2006

This Supplement sets forth certain changes to the Prospectus, dated May 1,
2006, of The Prudential Series Fund (the Fund) with respect to the indicated
Portfolios of the Fund.  Capitalized terms used in this Supplement and not
otherwise defined herein have the meanings given to them in the Fund's
Prospectus. The Portfolios discussed in this Supplement may not be available
under your variable contract.  For more information about the Portfolios
available under your contract, please refer to your contract prospectus.  The
following should be read in conjunction with the Fund's Prospectus and should
be retained for future reference.

I. Investment Policy Changes
The Board of the Trustees of the Fund (the Board) recently approved investment
policy changes for the Portfolios referenced below. Such changes will become
effective on or about May 1, 2007.

A.    SP International Value Portfolio
The investment and geographic focus for the SP International Value Portfolio
will change as described below. The Portfolio currently invests at least 80% of
its investable assets in issuers located in developed countries that are
represented in the MSCI EAFE Index. Under the revised investment policies, the
Portfolio will: (i) have a non-fundamental policy to invest, under normal
circumstances, at least 80% of the value of its assets in equity securities and
(ii) invest at least 65% of its net assets in the equity securities of foreign
companies in at least three different countries. The Portfolio will not change
its policy of investing at least 80% of the value of its assets in equity
securities unless it provides 60 days prior written notice to contract owners.

CURRENT INVESTMENT AND GEOGRAPHIC FOCUS
The Portfolio normally invest at least 80% of the Portfolio's
investable assets (net assets plus borrowings made for investment
purposes) in the equity securities of companies in developed
countries outside the United States that are represented in the
MSCI EAFE Index.  The MSCI EAFE Index tracks stocks in
Australia, Austria, Belgium, Denmark, Finland, France, Germany,
Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand, Portugal,
Singapore, Spain, Sweden, Switzerland and the United Kingdom.


REVISED INVESTMENT AND GEOGRAPHIC FOCUS
The Portfolio will have a non-fundamental policy to invest,
under normal circumstances, at least 80% of the value of
its assets in equity securities. The Portfolio will not
change this policy unless it provides 60 days prior written
notice to contract owners.

To achieve the Portfolio's investment objective, the
Portfolio will invest at least 65% of its net assets in the
equity securities of foreign companies in at least three
different countries, without limit as to the amount of
Portfolio assets that may be invested in any single
country. A company is considered to be a foreign company if
it satisfies at least one of the following criteria:

.  its securities are traded principally on stock
exchanges in one or more foreign countries;

.  it derives 50% or more of its total revenue from
goods produced, sales made or services performed in
one or more foreign countries;

.  it maintains 50% or more of its assets in one or
more foreign countries;

.  it is organized under the laws of a foreign
country; or
.  its principal executive office is located in a
foreign country.

The Portfolio may invest anywhere in the world, including
North America, Western Europe, the United Kingdom and the
Pacific Basin. The companies in which the Portfolio invests
may be of any size.




The primary risks associated with these changes are the risks of loss from: (i)
increased investments in emerging markets securities and (ii) increased
geographic concentration. Foreign investing involves special risks - including
currency risk and the possibility of substantial volatility due to adverse
political, economic, financial or other developments. Foreign securities may
also be less liquid and harder to value than U.S. securities. These risks are
greater for investments in the emerging markets in which the Portfolio may
invest. In addition, because the Portfolio may invest a large portion of its
assets in a single country or region of the world pursuant to the revised
investment policies, the Portfolio's investments can be geographically
concentrated. This can result in more pronounced risks based upon economic
conditions that affect a single country or region more or less than other
countries or regions.

B.  SP PIMCO Total Return Bond Portfolio, SP PIMCO High Yield Portfolio,
 and SP Diversified Conservative Growth Portfolio

Pacific Investment Management Company LLC (PIMCO) serves as a subadviser for
all or a portion of the assets of the above-referenced Portfolios. With respect
to these assets, PIMCO currently hedges at least 75% of each Portfolio's
exposure to foreign currencies to reduce currency risk. The Board approved a
revised investment policy that would permit each Portfolio to have foreign
currency exposure not exceeding 20% of the total assets directly managed by
PIMCO. In addition, with respect to futures contracts, each Portfolio currently
covers any open positions by segregating or earmarking liquid assets in an
amount equal to a specified percentage of the market value of the futures
contract. However, with respect to money market futures contracts, (which are
cash settled contracts and are marked to market on a daily basis), the revised
investment policy will permit each Portfolio to segregate or earmark liquid
assets in an amount equal to the
Portfolio's daily marked to market (net) obligation, if any, (or in other words
the Portfolio's daily net liability, if any). These changes may result in
increased currency risk, foreign markets risk, and derivatives risk for the
Portfolios.

C.   SP AIM Core Equity Portfolio

The Board approved increasing the Portfolio's ability to invest in foreign
securities from 20% of its assets to 25% of its assets. The Portfolio does not
expect to experience any material changes in its current investment strategy or
operations.
