What I learned the hard way:
1. ALWAYS use your better judgement, and double check what your vet recommends for your does. You know them better than you know yourself, get second opinions and educate yourself. Most vets are not familiar with Caprine diseases or their treatments. You can never be too careful when it comes to your doe's health.
2. ALWAYS feed your does pure alfalfa hay. It is imperative. My normal alfalfa hay supplier had dusty hay, so we ended up using our nice grassy horse hay instead. Don't make the same mistake!
3. If your does are eating more minerals than normal, check things out!
4. ALWAYS weigh your grain by weight, with a scale! I stupidly made the beginner mistake of feeding by measuring cups. Huge 'no, no' some grains are heavier than others. I will be weighing my containers of grain from now on (subtracting the container weight, the reason why I Adore Tare function), calculating the average, and feeding that amount from now on. Goat formulated grains usually contain enough vitamins and minerals by themselves, but if you forget to weigh them, you may end up paying a high price--your doe's health.
