Pasteurized vs Raw goat milk

I drank 32 ounces of raw goat milk 3 times a day nothing else. After few days my body started producing mucus in my throat. I didn’t experience fever or cold/cough just a lot of mucus started showing up in my throat. Mucus went away as soon I stopped drinking it.

I drank 16 ounces of pasteurized milk once to twice a day without experiencing any mucus. However, over time it make it easier to get sick with the cold sometimes weeks of continuous drinking milk or few months later.
