Helping Giant Pandas Conceive

I saw this on CNN.com.

They are showing videos of panda pornography to pandas to increase their sex drive so that they conceive. From one article:

Giant pandas, especially those in captivity, have such low sexual desires it is threatening their future, prompting workers to turn to artificial insemination to keep the endangered species going.

...

The Chengdu Giant Panda Breeding and Research Base in Sichuan Province is also in on the act, showing sex education films once in the morning and again in the evening.

"Through this kind of sex education, we expect to arouse the sexual instincts of giant pandas, enhance their natural mating ability and raise their reproductive capacity," said Zhang Hemin, director of the China Giant Panda Breeding and Research Center.

A video report at at CNN.

Yaakov Avinu did something similar. In Bereishit 20:

לז וַיִּקַּח-לוֹ יַעֲקֹב, מַקַּל לִבְנֶה לַח--וְלוּז וְעַרְמוֹן; וַיְפַצֵּל בָּהֵן, פְּצָלוֹת לְבָנוֹת--מַחְשֹׂף הַלָּבָן, אֲשֶׁר עַל-הַמַּקְלוֹת.	37 And Jacob took him rods of fresh poplar, and of the almond and of the plane-tree; and peeled white streaks in them, making the white appear which was in the rods.
לח וַיַּצֵּג, אֶת-הַמַּקְלוֹת אֲשֶׁר פִּצֵּל, בָּרְהָטִים, בְּשִׁקְתוֹת הַמָּיִם--אֲשֶׁר תָּבֹאןָ הַצֹּאן לִשְׁתּוֹת לְנֹכַח הַצֹּאן, וַיֵּחַמְנָה בְּבֹאָן לִשְׁתּוֹת.	38 And he set the rods which he had peeled over against the flocks in the gutters in the watering-troughs where the flocks came to drink; and they conceived when they came to drink.
לט וַיֶּחֱמוּ הַצֹּאן, אֶל-הַמַּקְלוֹת; וַתֵּלַדְןָ הַצֹּאן, עֲקֻדִּים נְקֻדִּים וּטְלֻאִים.	39 And the flocks conceived at the sight of the rods, and the flocks brought forth streaked, speckled, and spotted.

I would think that one could translate וַיֵּחַמְנָה and וַיֶּחֱמוּ as "went into heat."
