Much to learn, yes. For example, the COSG standard is rigorous.
The goat's vital signs are tested while it is standing up, while lying on its left side, lying on its right side, lying on its back with legs straight up, and in the difficult position of front legs on the ground, hind legs elevated so the body is at a 45 degree angle. Yes, 5 positions.
Well worth buying a goat that has met this standard.
Insist only upon Elabore or Chronometre grade goat.
