POLICIES WITH RESPECT TO SECURITY INVESTMENT

THE PRUDENTIAL SERIES FUND
NATURAL RESOURCES PORTFOLIO

SUPPLEMENT DATED FEBRUARY 9, 2007
TO THE
PROSPECTUS
DATED MAY 1, 2006

This supplement sets forth certain changes to the prospectus of The
Prudential Series Fund (the "Fund") dated May 1, 2006 with respect to
the Natural Resources Portfolio. The following should be read in
conjunction with the Fund's Prospectus and should be retained for
future reference.

I. Change to Non-Fundamental Investment Policy

Effective February 9, 2007, a non-fundamental investment policy for Natural
Resources Portfolio will change. The change is specifically discussed below.

Natural Resources Portfolio. The percentage of total assets that may be
invested in foreign equity and equity-related securities is increased from 30%
of total assets to 50% of total assets. To reflect this change, the indicated
sections of the Prospectus are revised as follows:

The first paragraph in the section of the Prospectus titled "Investment
Objectives and Principal Strategies of the Portfolios-Natural Resources
Portfolio" is deleted and replaced with the following:

   We normally invest at least 80% of the Portfolio's investable
assets (net assets plus any borrowings made for investment purposes)
in common stocks and convertible securities of natural resource
companies and securities that are related to the market value of some
natural resource. The Portfolio is non-diversified. As a non-
diversified Portfolio, the Natural Resources Portfolio may hold
larger positions in single issuers than a diversified Portfolio. As a
result, the Portfolio's performance may be tied more closely to the
success or failure of a smaller group of portfolio holdings. There
are additional risks associated with the Portfolio's investment in
the securities of natural resource companies. The market value of
these securities may be affected by numerous factors, including
events occurring in nature, inflationary pressures, and international
politics. Up to 50% of the Portfolio's total assets may be invested
in foreign equity and equity-related securities. While we make every
effort to achieve our objective, we can't guarantee success and it is
possible that you could lose money.

The eighth paragraph in the section of the Prospectus titled "More Detailed
Information on How the Portfolios Invest-Investment Objectives and Policies-
Natural Resources Portfolio" is deleted and replaced with the following:

   Up to 50% of the Portfolio's total assets may be invested in
foreign equity and equity-related securities. For these purposes, we
do not consider American Depositary Receipts (ADRs) and similar
receipts or shares traded in U.S. markets as foreign securities.
