I want to know the answer to the following question:
What is a major benefit to rabbits having a higher concentration of copper in their diet?
All the background I'm provided with is that "However, higher concentrations of copper (100 ppm, 200 ppm, or 500 ppm) in the diet of rabbits may favorably influence feed conversion efficiency, growth rates, and carcass dressing percentages.". Is that enough to answer the question?
