If I were to get goats (not looking like it at the moment), I was planning on Nigerian. The big issue is that I have never liked goat milk or cheese. However, a goat is probably easier than a mini cow. Also, I acknowledge that I may have hated the milk because of the breed of goats, or that I was just young. Taste buds change.
So I know I need to taste the milk before I buy the goat... Even if saying that makes me laugh because I have "Why buy the cow, when you can get the milk for free?" going through my head.
It's true - a few tips for milk - raw milk is sweet, and has a lot of goodness, and is more easily digestable. (in the us, there's only been about 800 people since 1998 that have had issues with raw milk - pretty much less than any other animal product, store bought or otherwise.)
However, cooking it does kill all the bacteria in the milk - but it also removes all the things that make it so good for you. If you're the one handling your goats, caring for them, knowing where they live, etc, then you can make a choice on how you want to drink the milk.
Limiting their eating to specific types of foods, will change the flavor of the milk - for example, if I eat a lot of garlic, my milk gets garlicy-flavored, and my toddler doesn't like to drink it. Same thing goes for goats. Give them hay, some grain, and table scraps - such as fruit/veggies. My milk will also change color, based on what I eat - or vitamins I take. b12 for example turns my milk *really* bright yellow for a few hours. haha
If they eat a lot of weeds, or plants that taste bitter, or funky, it will change the flavor of their milk, too. Keep your milking goats away from your buck, because his smell will rub all over them, and that musky scent can get into the milk.
Other than that you may have to play around with their diet, to get the right combination of food, to get a milk flavor you like.
years ago a friend of mine had worms in her poop she said, it has haunted me ever since!!!
I had worms once as a kid.... got it from a kitten.
