What are the basic principles for selective mating of cashmere goats?

First, the ram should be superior to the doe; when selecting a ram for a doe, he must be superior to the doe in overall quality and grade.

Second, use the ram's strengths to compensate for the doe's weaknesses; when selecting a ram for a doe that has weaknesses and deficiencies in certain respects, a ram with outstanding strengths in those respects must be chosen to mate with her, and a ram with the same weaknesses must never be used.

Third, use inbreeding selectively with caution.

Fourth, summarize and analyze in a timely manner. If the results are good, selective mating can be carried out again according to the original plan; otherwise, the original mating plan should be revised and a different ram should be used for mating.
