Behold, the hand of the LORD is upon thy cattle which is in the 
field, upon the horses, upon the asses, upon the camels, upon the oxen, and upon the sheep: there shall be a very grievous murrain.
And the LORD shall sever between the cattle of Israel and the cattle of Egypt: and there shall nothing die of all that is the children's of Israel. And the LORD did that thing on the morrow, and all the cattle of Egypt died: but of the cattle of the children of Israel died not one.
Exodus 9:3,4,6
"The 5th plague, on the livestock (which provided food, milk,
clothing and transportation), was a direct attack on Apis, the sacred
bull god, and Mnevis, a bull-god symbol of fertility, as well as Hathor,
the cow-like mother goddess, and Isis, the queen of the gods, who wore a
cow’s horns on her head.
They were all shown to be imposters."
