From The Long Lost Friend:
To Treat A Cow After Milk Is Taken
Give to the cow three spoonfuls of her last milk, and say to the spirits in her blood: "Ninny has done it, and I have swallowed her in the name of God the Father, the Son, and the Holy Ghost. Amen." Pray what you choose at the same time.
