Awais Baig, [05 Oct 2024 at 21:11:22]: Hi Does anyone have serum chemistry values for vitamin and macronutrients for cheetahs? We are doing a project for cheetah conservation in Riyadh, it's needed for their health checkups. If anyone can help regarding that I will be thankful. Riyadh Zoo. KSA Adrian Tordiffe, [06 Oct 2024 at 05:55:31]: Dear Dr Awais. Unfortunately, there are no published reference values for cheetah serum or whole blood vitamin or mineral concentrations. Such reference values have not even been established for domestic cats. The problem is that there is little agreement on the best methodology and then more importantly that serum levels do not often provide a good estimate of total body reserves. My approach is to rather look at the diet in captivity and compare it in terms of composition to what they would get in the wild. I then calculate the vitamin and mineral deficiencies based on the diet.
