I have kept goats since 1987. I very rarely buy milk.
Talk about cheap upkeep. They can live off of the very weeds that you are cutting and mowing to get rid of!
I noticed that my holiday from twice a day milking is almost over, they will be having babies soon, and it will be milk the mama's and bottle the babies.
I leash trained the does last year, and hope to order a driving harness for them this year. Then it is move on up to a plow and a cart that are goat drawn.
I also have Great Pyrenees Mountain Dogs, not as cheap to feed, but, close to the same size as the goats, so I am thinking, they could also be trained to pull a plow or cart... free labor?
When you raise your animals for yourself, they are friendly, and just want to be where you are. I can go for a walk and not need a leash, they want to be where I am. Now, if I also pack train them... they could carry home the blackberries even in terrain too rough for a cart! Although I would need to put something over their udders to protect them from scratches. Pack dogs too? I wonder?
Sure you need to feed them, worm them, and vaccinate as necessary, but for most of us, basic upkeep like that is alot cheaper than the feed bill. Well, with goats you get 75% of their food for free!
Add the male kids go into the freezer, the milk becomes yogurt, kefir, butter, cheese (I am still working on this one), and can be canned or frozen.
They are now coming out with miniature dairy goats, these are various sized based on if they are first, second, or third generation, but they are real dairy animals, in a portable size.
Please consider goats as a major part of any survival, self sufficiency plan, if you have the room to get some.
Goat milk tastes exactly like cows milk, if you feed them well, and are clean in your milk handling. And compared with the upkeep of most other animals that could help with chores... they will help ya... just for the "weeds".
