We have a new dairy goat, Isabelle. She kidded on July 10th and we got her four days later. When we first got her, her milk was good and sweet, but lately it seems to be getting more and more bitter. It's not goaty-tasting at all, and I'm almost sure the problem is not sanitation or cooling it fast enough. I'm wondering if she's missing something in her diet. Would that cause her milk to be bitter? By the way, her production is not suffering, just the flavor. Thank you. - Stephanie
