Bible Verses About Animals: Facts about breeding

That very day Laban removed all the streaked or spotted male goats and every speckled or spotted female goat—every one that had any white on it—and every dark-colored lamb, and he placed them under the care of his sons.

Then he put a three-day journey between himself and Jacob, while Jacob was shepherding the rest of Laban’s flocks.

Jacob, however, took fresh branches of poplar, almond, and plane trees, and peeled the bark, exposing the white inner wood of the branches.

Then he set the peeled branches in the watering troughs in front of the flocks coming in to drink. So when the flocks were in heat and came to drink,

they mated in front of the branches. And they bore young that were streaked or speckled or spotted.

Jacob set apart the young, but made the rest face the streaked dark-colored sheep in Laban’s flocks. Then he set his own stock apart and did not put them with Laban’s animals.

Whenever the stronger females of the flock were in heat, Jacob would place the branches in the troughs, in full view of the animals, so that they would breed in front of the branches.

But if the animals were weak, he did not set out the branches. So the weaker animals went to Laban and the stronger ones to Jacob.

Thus Jacob became exceedingly prosperous. He owned large flocks, maidservants and menservants, and camels and donkeys.

If he said, ‘The speckled will be your wages,’ then the whole flock bore speckled offspring. If he said, ‘The streaked will be your wages,’ then the whole flock bore streaked offspring.

Thus God has taken away your father’s livestock and given them to me.
